What is the effect of the ignition advance angle on the engine?

Category:Automobile engine repair - Date:2017-03-26

the ignition advance angle has great influence on the power and economy of the engine. The gas pressure has reached a great value, when the gas pressure is opposite to the direction of the piston movement. Sometimes the crankshaft is reversed to make the engine fail to work. If the ignition advance angle is too small, the piston moves a certain distance down to the stop point at the beginning of the combustion. This loses a part of the expansion work and the combustion is carried out in the work stroke. The contact area between gas and cylinder wall is large, the heat transferred to the cooling water increases, the combustion pressure decreases, the power of engine decreases, and the fuel consumption increases.
