新型轿车发动机与过去的发动机相比,发生爆燃的机会较少,但一旦发生,却更难查找原因,从而也更难解决问题。新装置带来了新问题。例如,排气再循环装置、敲缸传感器、高能点火系统的离心调节器等,都成为引发爆燃的新因素。因此,爆燃检验也必须从这些方面着手。 New car engines have fewer opportunities for a deflagration than in the past, but in the event of a problem, it is harder to find the cause and make it harder to solve the problem. New device has brought new problems. For example, exhaust gas recirculation devices, knock cylinder sensors, high-energy ignition system centrifugal regulators, etc., have become the new trigger deflagration factor. Therefore, the deflagration test must also start from these aspects.
