System of injection of fuel of the petrol engine The general information and security measures at work The car is equipped by an electronic digital control system of the engine (DME/BOSCH-MOTRONIC).The electronic control system of the engine allows to realise following advantages: - Exact dosage of fuel in any mode of operation that provides the small expense of fuel at high capacity. - Reduction of the maintenance of harmful substances in the fulfilled gases thanks to exact dispensing of fuel and application catalytic the converter. - Self-diagnostics of a control system by the engine, provides possibility of fast troubleshooting. The control system of the engine has memory of malfunctions. If defect it is brought in memory of the device while in service comes to light. If the engine has malfunctions by means of the special device it is possible to deduce their list, allowing to reveal and eliminate defect independently. Address to Section Diagnostics of malfunctions. Work it is desirable to spend HUNDRED in conditions. The engine management block represents the minicomputer with high speed. It defines optimum time of injection and quantity of injected fuel. Thus there is a coordination of work of the block of management with other systems of the car, for example, to a control system of a check point or blocking from stealing. Elements of a control system of the engine keeps the high working capacity for a long time and practically does not demand service. Replacements at carrying out of maintenance service demand only the air filter and spark plugs. Serious works on adjustment and repair demand application of difficult diagnostic devices. Address to Section Diagnostics of malfunctions. Adjustment of number of turns of idling and concentration WITH within the limits of maintenance service carrying out is not required. Security measures at work with a control system of the engine / the petrol engine The fuel system is under pressure! At system opening fuel emission is possible. Therefore the flowed out fuel is necessary for wiping a rag. Gasoline steams are poisonous and горючи. Use goggles. Watch good ventilation of a workplace. Have on call the fire extinguisher. For an exception травмирования and-or damages of system of injection and ignition the following is necessary to observe people: - Do not concern and do not disconnect ignition wires at the working engine or at the included starter. - Disconnect and attach pipelines of system of injection and an ignition wire, and also electric wires of devices of measurement only at the switched off ignition. - It is not supposed to work with electronic system of ignition to people with a warm stimulator. - At compression check it is not supposed to make fuel injection.
