Check and adjustment of installation of a corner of an advancing of ignition/injection of fuel of the petrol engine
The general information The ignition moment is measured in degrees of an angle of rotation of a cranked shaft of the engine and is important for operation of spark plugs at a given time a compression step. It is ideal, if the spark from a spark plug sets fire to an air-fuel mix in the chamber of combustion at the moment of passage by piston VMT of a step of compression. In this case the air-fuel mix will burn down and extend. Extending gases will push the piston downwards in a working course, rotating, thus, a cranked shaft. For full поджига a working mix fractions of a second are required. Therefore for observance of normal working process of combustion (full combustion of a mix) in the engine some advancing of ignition is necessary. The advancing is measured in degrees to ВМТ. If the engine advancing makes 7 degrees to ВМТ, it means that pressure on a candle should arrive while the cranked shaft is in 7 ° to ВМТ a step of compression of the first piston. However, it is fair only for a case when the engine works on single turns. If the cranked shaft rotates faster, means, also pistons faster move. Therefore for full burning of a mix of a candle should set fire to it even earlier. To answer these conditions, ECU corrects the ignition moment according to increase in speed of rotation of the engine. Electronic control by the ignition moment is known under name ESA and is defined by program ECU. Tracing speed of rotation of a cranked shaft, weight of soaked up air, engine temperature, position throttle заслонки and other factors, microprocessor ECU operates the ignition moment on all power setting from cold start to a mode of full loadings. System simple, noncontrollable and reliable. Check |
