微机控制汽油机点火系以提高点火能量

本文介绍了一种利用微型计算机控制汽油机点火系以提高点火能量的方法,用微机控制初级电路导通的时间,同时减小初级回路的电阻,使得断开电流增大而又不致烧坏点火线圈,提高了点火能量以及最大次级电压,从而可增大火花塞间隙,试验表明用此方法可以燃烧更为稀薄的混合气,使油耗率大为下降。

Improving the Sparking Energy of Gasoline Engine with Micro-computer Control Ignition System

In this paper, a micro-computer control ignition system for improving the sparking energy of gasoline engine is described. The conducting time in the primary circuit is controlled, and the resistance is reduced, consequently the cut-off current is augmented but the coil shouldn't burn out. It improves the sparking energy and the maximum voltage in the secondary circuit, so that the spark gap of the plugs may be increased. The experiments show that by this way, leaner mixture can be burned and the specific fuel consumption of gasoline engines is reduced enormously.
