Замена топливного фильтра на Калине своими руками

Одним из основных условий стабильной работы любого автомобиля является качественное, чистое топливо. Для очищения топливной смеси на машину устанавливают специальные фильтры. Обычно используется два типа этих расходников: грубой очистки (представляет собой сеточку и ставится на приемник забора горючего) и тонкой очистки (устанавливается между бензобаком и двигателем). В зависимости от вида топливной системы, различают фильтры для карбюраторных, инжекторных и дизельных двигателей. На все модификации Лада Калина устанавливаются инжекторные моторы.

Когда необходимо заменять топливный фильтр

Инжекторы Лады Калины очень чувствительны к чистоте подаваемого топлива. В случае засорения фильтра во время движения авто водитель немедленно ощутит рывки и дергание. Особенно это заметно на малых скоростях. Поэтому не следует дожидаться появления описанных неисправностей и своевременно заменить деталь. Срок эксплуатации расходного материала, указанный в технической документации к машине, составляет 50 тысяч километров пробега. Но автолюбители советуют не ориентироваться на этот показатель.

Так как топливо на российских бензоколонках не отличается высоким качеством, рекомендованная периодичность замены составляет 30 000 километров пробега.

Топливный фильтр имеет монолитную конструкцию, поэтому невозможно провести визуальную оценку его состояния. Но определить его пропускную способность достаточно просто по давлению на выходе, подсоединив к выходному шлангу манометр. При работающем бензонасосе давление должно составлять 2,7 атмосферы. Если оно ниже указанной нормы, требуется заменить расходник.

Выбор фильтра на Калину

Несмотря на большое разнообразие фильтров на рынке запасных частей и расходных материалов, они одинаковы для всей линейки данных авто от АвтоВАЗа. Топливная система Лада Калина ничем не отличается в машинах с двигателями, имеющими один распредвал и 8 клапанов, и с двухваловыми моторами с 16 клапанами. Сам расходник во всех машинах находится под топливным баком в правой части кузова.

Чтобы правильно выбрать фильтр, необходимо разобраться в особенностях его конструкции. Основной составляющей этого расходного материала является фильтрующий элемент, который характеризуется двумя важными показателями: площадь и размер ячеек, или пористость. Обычно он изготавливается из специальных сортов бумаги. Для увеличения площади фильтрации бумажную полоску складываю в гармошку, затем склеивают края. Полученную конструкцию в виде гофрированного цилиндра помещают в металлический или пластиковый корпус, имеющий два штуцера для входящего и выходящего потоков.

Описанная конструкция характерна для всех известных топливных фильтров без исключения, вне зависимости от производителя, поэтому оценка эффективности работы этого устройства проводится по площади (или диаметру) фильтрующего элемента, размеру ячеек и числу ребер.

Высококачественный топливный фильтр на Калину обладает большой площадью (или диаметром) и мелкими ячейками.

Фильтры по диаметру, размеру ячеек и количеству ребер

Бренд	Диаметр фильтрующего элемента, мм	Размер ячеек, мкм	Количество ребер
Lada Big	44	50	38
SCT	42	50	55
Pekar	41	50	48
Hola	42	55	54
Ween	41	50	45
Bosch	48	45	65

Анализ результатов исследований показывает, что в первой группе наилучшими показателями обладают товары брендов «JC Premium», «General Motors» и «Mann», которые имеют максимальную площадь фильтрующего элемента и минимальный размер ячеек. Во второй группе лидером является «Bosch», отличающийся большим диаметром, маленькими ячейками и максимальным количеством ребер. Самые хорошие образцы, как правило, наиболее дорогие.

Как поменять расходник

Замена топливного фильтра на Калине проходит по тому же алгоритму, что и на других моделях авто. Деталь является расходным материалом и не подлежит ремонту, однако ее довольно просто заменить своими руками. Прежде всего необходимо сбросить давление в топливной системе — для этого нужно обесточить бензонасос. Эту процедуру можно выполнить двумя способами:

1. Вынуть предохранитель, отвечающий за работу насоса (он находится под крышкой, рядом с ручкой коробки переключения передач).
2. Откинув задние сиденья, снять металлическую заглушку и отсоединить провод питания бензонасоса.

Затем необходимо завести двигатель и сжечь оставшееся топливо в системе, сбросив в ней давление. Когда мотор заглохнет, можно приступать к демонтажу фильтра, который находится с правой стороны топливного бака. Для этого нужно снять входящий и выходящий шланги, отжав пластиковые клипсы, после чего демонтировать расходный материал с фиксирующего кронштейна. Поскольку в топливопроводах и в самом фильтре есть остатки топлива, требуется приготовить небольшую емкость для их слива. Установка нового расходника производится в обратном порядке.

При монтаже нового фильтра необходимо повернуть его корпус в соответствии с изображенной на нем стрелкой, чтобы она совпадала с направлением движения топлива.

Топливный фильтр надежно защищает форсунки от загрязнения. Он обеспечивает бесперебойную работу двигателя, потому менять расходник необходимо своевременно. Для автомобиля Лада Калина существует огромное разнообразие фильтров различных брендов. Хотя практически все расходники такого типа производятся в Китае или Южной Корее, разброс цен на них очень широкий. За фильтр известного бренда придется выложить немалую сумму.

90000 How to Change Your Vehicle’s Fuel Filter 90001 90002 90003 90004 90003 Home & Garden 90004 90003 Car Repair 90004 90003 Fuel System 90004 90003 How to Change Your Vehicle’s Fuel Filter 90004 90013 90014 By Deanna Sclar 90015 90014 Changing the filter on a fuel-injected vehicle can be tricky. On fuel-injected vehicles, you need to disable the fuel pump to relieve the pressure on the fuel lines, which may be secured to the filter with clamps, threaded fittings, or special quick-connect fittings.Lines with threaded fittings require a special flare-nut line wrench. Lines with special quick-connect fittings may require special tools to disconnect them. Ask the clerk at an auto parts store or the service department at your dealership which type of filter your vehicle has. 90015 90014 If doing this infrequent job requires purchasing special tools, it’s probably cheaper to have it done by a technician. If not, the first thing you need to do is find the filter. Your owner’s manual should show you where your fuel filter is and whether there’s more than one on your vehicle.If it does not, ask someone in the service department at your dealership or consult a service manual for your vehicle’s make, model, and year. (Although it’s a good idea to own one, you can usually find these manuals at your local library.) 90015 90014 If your engine has fuel-injection, your fuel filter is located somewhere in the high-pressure fuel line, either under the vehicle near the fuel tank as shown here: 90015 90014 A fuel filter located under the vehicle near the fuel tank. 90015 90014 Or under the hood in the fuel line near the engine, as shown here: 90015 90014 A fuel filter in the fuel line under the hood.90015 90014 Some vehicles also have a fuel filter in the fuel pump as well as a filter screen inside the fuel tank. If they get blocked up, only a professional should deal with them. 90015 90014 Here are step-by-step instructions for changing a fuel filter. Before you get started, read them carefully and make sure that you want to do this job yourself. 90015 90002 90003 90014 Relieve the pressure in the fuel line before disconnecting it. To do so, you have to disable the electric fuel pump before you start the engine.90015 90014 To disable the fuel pump, do the following: 90015 90002 90003 90014 With the engine off, remove the fuel pump fuse from the fuse box. (Your owner’s manual should show you where it is.) 90015 90004 90003 90014 Make sure that the parking brake is on and that the vehicle is in Park or Neutral, and then start the engine. It will not run very long after you start it up, but the pressure in the fuel lines will be reduced. 90015 90004 90003 90014 Turn off the engine. With the fuel pump disabled, you’re ready to disconnect the fuel lines from the filter.90015 90004 90013 90004 90003 90014 Look at the old filter and the new one before disconnecting anything. 90015 90014 You should see an arrow stamped on both filters that shows in which direction the fuel flows through it. If the new one does not have an arrow on it, look to see in what direction the old filter is installed so that you can tell which end of the new filter goes where. 90015 90004 90003 90014 Remove whatever is holding the old filter in place and remove it. 90015 90004 90003 90014 Put the new filter on in the same position as the old filter.90015 90004 90003 90014 Replace whatever holds the filter in place, and make sure it’s secure. 90015 90004 90003 90014 Replace the fuse for the fuel pump in the fuse box. 90015 90014 Make sure that the parking brake is on and that the vehicle is in Park or Neutral, and then start the engine and check for leaks around the filter. 90015 90004 90013 .90000 How to Replace the Fuel Filters in Your Outdoor Power Equipment: eReplacementParts.com 90001 Fuel filters remove debris before it hits the carburetor in your gas-powered lawn equipment.

[Back to Top] What We’re About 90006.90000 How to Replace a Fuel Injector 90001 90002 All modern vehicles with injection systems use indirect injection. A fuel pump pushes fuel under pressure from the fuel tank to the engine fuel rail. Depending on the particular system, the fuel is sprayed into either the inlet manifold or the inlet port. This works much like the spray nozzle from a spray bottle, ensuring that the fuel comes out as a fine mist, known as atomization. The fuel mixes with the air passing through the inlet manifold or port and the fuel / air mixture enters the combustion chamber.90003 90002 Some cars have multi-point fuel injection where each cylinder is sprayed by its own injector in an intake port. This type of system is complex and can be expensive. It’s more common to have single-point injection where a single injector feeds all the cylinders, or to have one injector to every two cylinders. 90003 90002 Performance vehicles have direct fuel injection where each cylinder is sprayed by its own injector directly on top of the cylinder in the combustion chamber. This is common on vehicles with hemispherical cylinder heads.90003 90002 There are two types of fuel injectors on vehicles: continuous injection and timed injection. Continuous injection is where the fuel is squirted into the inlet port always as the engine is running. The injector simply acts as a spray nozzle to break up the fuel into a fine spray; it does not actually control the fuel flow. The amount of fuel sprayed is increased or decreased by a mechanical or electrical control unit; in other words, it is just like turning a tap on and off. 90003 90002 Timed injection, or pulsed injection, is where the fuel is delivered in bursts to coincide with the induction stroke of the cylinder.As with continuous injection, timed injection can also be controlled either mechanically or electronically. 90003 90002 Some vehicles use multiple fuel injectors for each cylinder. Cold start injectors are used to help aid the combustion when starting vehicles in cold climate weather conditions. Cold start injectors are usually located on the intake runner rather than the intake port. Pre-injectors are designed to help aid in the main injector for more performance. This is when the operator presses the accelerator pedal to the floor causing the secondary injector to spray.This allows more fuel to mix into the combustion chamber creating more power. 90003 90002 A bad fuel injector manifests itself in a number of ways, whether in engine performance issues or the smell of fuel in the car, or even a sign as simple as a check engine light. 90003 90002 90003 90002 The following are engine light codes related to the fuel hose on vehicles with computers 90003 90002 P0087, P0088, P0170, P0171, P0172, P0173, P0174, P0175, P0213, P0214 90003 90022 90023 90024 Note 90025: It is recommended to replace the fuel injectors with original manufacturer equipment (OEM).Aftermarket fuel injectors may produce more or less power that specified for the vehicle. Also, aftermarket fuel injectors may have different electrical connections making the vehicles harness not match up. 90026 90027 90028 Part 1 of 6: Verifying the condition of the fuel injector condition 90029 90002 90024 Step 1: Start the engine 90025. Check the dash for any engine lights and listen to the engine operation for any cylinders not firing correctly. 90003 90002 Feel for any vibrations during engine operation.90003 90002 90024 Step 2: Shut the engine off and open the hood 90025. Check for any wiring that may be broken or damaged around the injectors. 90003 90002 If your vehicle has individual injectors per cylinder and you can disconnect them, start the engine and disconnect one injector at a time. This is a test procedure called a cylinder cut out test, allowing you to determine if the disconnected injector causes the engine to become rough running or develop no change. If there is no change, then the injector was not working.90003 90028 Part 2 of 6: Removing the fuel injector 90029 90002 Having all of the necessary tools and materials prior to starting the work will allow you to get the job done more efficiently. 90003 90002 90024 Materials Needed 90025 90003 90022 90023 Allen wrench set 90026 90023 Boxed end wrenches 90026 90023 Drip pan 90026 90023 Flashlight 90026 90023 Flat tip screwdriver 90026 90023 Floor jack 90026 90023 Fuel hose quick disconnect kit 90026 90023 Fuel resistant gloves 90026 90023 Jack stands 90026 90023 Protective clothing 90026 90023 Ratchet with metric and standard sockets 90026 90023 Safety glasses 90026 90023 Torque wrench 90026 90023 Torque bit set 90026 90023 Wheel chocks 90026 90027 90002 90024 Step 1: Park your vehicle on a flat, hard surface 90025.Make sure that the transmission is in park (for automatics) or in 1st gear (for manuals). 90003 90002 90024 Step 2: Place wheel chocks around the rear tires 90025.

The bulb pulls fuel through the filtered fuel line and into the carburetor and then it also pushes it out of the carburetor and out the unfiltered return line. 90033 90003 90002 90005 With correct 90006 fuel line 90005 installation 90006, 90005 fuel is pulled in through 90006 the line with 90005 the fuel filter 90006 and 90005 pushed 90006 out out 90005 the unfiltered 90006 return 90005 line 90006.After mixing up the fuel line orientation, performing a test is the only way to make sure that the lines are installed correctly. [Back to top] 90033 90003 90002 90005 1. Install the lines and test the orientation. 90006 90033 90003 90002 Make a guess and 90005 install the lines 90006 on the carburetor. 90003 90002 90005 Test the orientation 90006 of the fuel lines by placing the ends of both lines in 2-cycle fuel (never water) and then prime the bulb.90003 90002 90003 90012 90013 If fuel is pushed out of the unfiltered line, then the orientation was guessed correctly and the test is complete. 90033 90016 90013 If bubbles emerge from the line with the fuel filter (pictured above), then the lines were installed incorrectly, must be switched, and then tested again. 90016 90023 [Back to top] 90002 90005 2. Reverse the lines and perform the test again (if needed). 90006 90003 90002 In the event that bubbles emerge from the fuel filter during the test, reverse the lines and perform the test again.90003 90002 90003 90002 Bubbles out the unfiltered return line verify that the new fuel line placement is correct. 90003 90002 [Back to top] 90003 90002 90031 90005 Fuel Line Routing for «Remote Primer» 2-Cycle Engine Carburetors 90006 90035 In the carburetor design pictured below, the primer assembly is separate from the body of the carburetor. 90003 90002 The fuel line routing for these «remote primer» carburetors is just a little more complex than the routing of local primer carburetors because of the addition of a third line.The important thing to remember with 90005 remote primer carburetors 90006 is that the primer assembly needs to 90005 90101 pull 90102 fuel through the carburetor 90006, 90101 not 90102 push the fuel into the carburetor. 90003 90002 The diagram above represents the correct flow of fuel through a remote primer carburetor. To determine the correct fuel line routing for remote primer carburetors, follow the steps below. [Back to top] 90005 1. Test the primer assembly.90006 90003 90002 Fuel only flows one way through primer assemblies. 90003 90002 So, the first step in determining the overall fuel line routing in this type of carburetor is to determine which are the input and output sides of the primer. 90003 90002 90003 90002 Attach fuel lines to the primer assembly, submerge both lines in some 2-cycle fuel, and prime the bulb. 90003 90002 Bubbles will emerge from the fuel line attached to the outgoing side of the primer — the return line — meaning that fuel is being pulled through the line that is not producing bubbles.90003 90002 The line not producing bubbles is the one that must be attached to the carburetor, since fuel must be pulled through the carburetor and into the primer bulb. [Back to top] 90033 90005 2. Test the fuel line routing with the carburetor. 90006 90003 90002 Attach the incoming line on the primer assembly to one of the ports on the carburetor and attach a third fuel line to the other carburetor fuel line port. 90003 90002 Submerge the ends of both fuel lines in some 2-cycle fuel and test the line configuration by depressing the primer bulb.90003 90002 90003 90012 90013 If bubbles and / or fuel emerge out of the primer assembly return line, then the line configuration was guessed correctly and the test is complete. 90016 90013 If the primer bulb becomes stuck or returns very slowly after being depressed (pictured above), then the line configuration was guessed incorrectly and the test must be conducted again. 90016 90023 [Back to top] 90005 3. Reverse the lines and perform the test again (if needed).90006 90033 90002 If the primer bulb sticks or returns slowly in the first test, switch the positions of the fuel lines on the carburetor and perform the test again. 90003 90002 90003 90002 Bubbles will emerge from the primer assembly’s return line when the line routing is correct. If the primer assembly return line is lifted out of the fuel while priming, fuel will be seen squirting from the line.
