Fuel Injection System for Gasoline Engines — Description Cars with gasoline engines are equipped with electronic injection systems of various modifications. 1.4 liter petrol engine (E7J) equipped with BOSCH Mono-Jetronic system, 1.4 liter petrol engine (K4J), as well as 1.6...
Ignition and fuel injection systems — general check To carry out systematic checks of the condition of the fuel injection system or to eliminate the identified malfunctions, special measuring instruments are required. They are usually very expensive and are available...
Mono-Jetronic fuel injection system — principle of operation Vehicles with 1.4 liter engine The Mono-Motronic system is an electronic fuel injection system for gasoline engines. Fuel is injected intermittently into the header pipe. Unlike other injection systems, Mono-Motronic...
MPI Multipoint Fuel Injection System — Principle of Operation Vehicles with a 1.6-/2.0-liter petrol engine The electronic multipoint injection system has four injectors, one for each cylinder. The injectors inject fuel into the intake valves sequentially, each one individually...
Catalyst and lambda probe — check If, when checking the CO content, it was found to be in excess, then the condition and functioning of the catalyst should be checked. 1. Make sure that leaded gasoline has not been filled into the tank when refueling....
Throttle body — removal and installation Vehicles with a 1.6-/2.0-liter petrol engine The throttle body needs to be removed for many jobs in the engine bay. Removing 1. Remove the air filter. 2. Disconnect the plugs of the intake air temperature sensor 1, as...
Fuel injectors — check Vehicles with a 1.4-/1.6-/2.0-liter petrol engine (except for 1.4 liter E7J engines). Leaky fuel injectors make it difficult to start a hot engine, cause the engine to run erratically, and cause misfiring. 1. Start the...
Fuel injectors — removal and installation Removal and installation of injectors are shown on the example of cars with a gasoline engine of 1.6 ligres (K7M). For vehicles with a 2.0 liter petrol engine, the procedure is identical. Differences in the removal and...
