Cars are equipped with the following injection systems.
Engine 2.0 l with eight valves (OHC) equipped with a multi-position injection system manufactured by Bosch type Motronic M1.5. Since mid-1995, a new system of the Motronic M1.5.4 type has been installed. It is a single engine management system. In engines of this type, a new exhaust gas recirculation system is installed (EGR), which sends up to 15% of the exhaust gases to the combustion chambers of the engine. The entire series of 2.4 l engines is equipped with the specified injection system.
New 2.2L engine (DOHC), belonging to the series "ECOTEC" with 16 valves, equipped with a multi-position injection system, Motronic 15.4 version. The engine has knock control, an electronically controlled exhaust gas recirculation system, and a secondary air mixing system. It should be borne in mind that this system has not been installed since 1997.
Although, as already mentioned, repair work is not carried out on the injection system, a description of the main elements of the system is given here. Basically, a description of the Motronic M1.5.4 system is given. A description is also given of older injection systems.
To carry out any work in accordance with the instructions given, it is necessary to have some experience with injection systems and related ignition systems. We do not bear any responsibility for any damage that may occur as a result of unskilled intervention in the elements of the system.
