FIXING CAR FUEL INJECTION SYSTEM

Early ideas made the fuel injection system on a gasoline car inspired by the pump fuel injection diesel engine was found by Robert Bosch. In a nutshell since the year 1960, VW car companies already use injection system D-Medtronic, was the first to use an electronic control system. Since the current system of Fuel Injection on a gasoline engine (EFI) is the more developed and have become better.

Fuel injection system/EFI petrol on the car is used primarily to reduce exhaust emissions so that more environmentally friendly, fuel-efficient, good engine performance, as well as fewer treatments. Well, that's why fuel system a conventional gasoline engine aka carburetor began to be abandoned by the automotive industry.

As usual, the name of the technology certainly did not escape from deprivation. For EFI systems, its main deficiencies are to be handled by special EFI technicians and have the proper equipment. Thus, when your vehicle strikes anywhere due to problems with the injection system, then there is no other way except model must be towed to a repair shop. However, a common problem on the injection system or EFI will be avoided if you are orderly conduct routine maintenance as specified in the vehicle service book issued by the manufacturer.

A Common Problem That Is Common On Car Engine Fuel Injection System

When there is a problem with the injection system is also demonstrated by the lights check engine on a car dashboard. To check on your chain of electronics covers all sensor-sensor and actuator, then the tool used is a digital multimeter, the test lamp, scanner, to the oscilloscope. The following problems could occur on a car when a troubled injection system:

The Machine Can Not Live, And Starter No Problem

The engine hard-living or living but trembling voice is indeed a problem that often occurs at the injection system, however, this also applies to damages on the part of the other. Therefore needs to be done to find the troubleshooting problem.

Well for that before examining the parts of the injection system, it needs to be checked first if the ignition system is still optimal. A section on the injection system that should be checked is the start of the fuel flow, signal towards the injector, check air intake leakage throttle, IAC sensor, ECT, folder, the pressure of compression, and lastly check the possibility of damage to the ECM.

Wastes Fuel

If there is a disruption in the system, then the EFI engine can also be wasteful of fuel, but can also be caused by other problems. For that thing to also review other than the injection system is the ignition system starting from components including spark plugs, spark plug wires, to slip the clutch and timing settings.

Damage/deterioration that could happen which includes injection system is; the TPS sensor, ECT/folder that is not appropriate, the damage to the fuel delivery system, VVT is damaged, and damage to the ECM. EGR valve that does not match (if fitted), the imperfect valve seating, low compression, the defective thermostat can also cause wasteful fuel injection system on the machine.

The Engine Choked

This can be felt when Accelerator released especially when the vehicle is running in all the gear speed. Damage or general problems that occur on the system is injector; ranging from electronic sensors namely TPS, ECT/folder that puny, VVT system broken, problems in ECM, injectors, fuel pressure is not appropriate, and the EGR valve does not work. Other damage can also cause a problem the engine bogged down was plug damage or cracks, as well as a low compression engine and the heat could also be a possibility of other causes that need to be examined.

Lackluster Engine Or Not Powered

The problem the engine feels sluggish and lackluster is a common problem on the injection system. This requires an examination performed intensively the infinite in the injection system. As the above problem, problem other than injection problems could be the cause is; damage to the ignition coil, the spark plug/spark plug cable coil, ignition is damaged, fuel pipe blockage, leakage gasket/gasket on intake manifold, engine overheating, setting the wrong gas cable, slip clutch, brakes jammed, low compression. For injection system that needs to be checked is all sensors, VVT, ECM, injectors, EGR and if equipped.

The machine cannot be idling or round idle does not match the specification is too high/low If EGR valve is fitted this needs to be checked is likely to occur a problem or nuisance problem idling, including injector, TPS sensor, ECT/folder weak, VVT, damage and breakage or weak vacuum hose. Weak compression, engine overheating can also be the cause.
C02 On Excessive Exhaust Gas.

Damage to the spark plug and the spark plug wires that are already saggy or leaked, Coil/Igniter is damaged, weak, compression of the pollution on catalytic converter, damage to the systems control emissions, fuel pressure spec does not match, the system of feedback the TP sensor damage problematic, sensor ECT/folder, damaged injectors, ECM is damaged, abnormal engine temperatures, clogged air filter, vacuum leaks, and possible damage to the system VVT.

The Nitrogen Content Of Oxides/NOx

This will be known when the exhaust gas test is done, even so, conditions can indicate excessive NOx problem on the machine especially the fuel injection system. Engine too hot or too efficient could have caused the fuel injector or oxygen sensor problems that eventually led to NOx. Problem with the fuel pump can also be the cause. The catalytic converter could be the cause but merely catalytic converter system for a special three-way. Carbon buildup and the problem could also be the EGR valve cause.

Problem with the car's engine is indeed diverse, sometimes one problem could be caused by a system other than the injection system e.g. ignition systems etc. Therefore required a series of checks that we refer to as troubleshooting to be able to find the real problem.

Specifically to find out the problem of damage to the injection system, then it takes some special tools namely scanners, digital multitester, test lamp led, an oscilloscope. To ensure accuracy in determining the layout of the disorders of the injection system situated on the procedures and the reading scanner tool on the basis of the technical data of the vehicle/machine that should.
