Why does pushing the car help when it won't start?
1 Answers
Because the battery is low on power and the starter cannot start the engine, pushing the car helps. The method involves putting the car in gear and pushing it, allowing the chassis to drive the engine and provide an external rotational force to ignite the engine. However, if the issue is not a weak battery or a faulty starter—such as an engine malfunction itself—pushing the car will not help, and the engine still won't start. Below is relevant information: 1. Working Principle: The principle is simple: after the engine is turned off, the starter gear remains engaged with the flywheel without disengaging. When the car is pushed, the force causes them to separate. Hence, pushing the car can help restart the engine. 2. Reasons for Failure to Start: When the battery voltage is insufficient to power the motor normally, the car won't start. However, the battery may still have enough power to supply the high-voltage coil for ignition. In such cases, putting the car in gear (usually 3rd gear is most suitable) and pushing it manually will cause the gear to drive the generator crankshaft. Once the crankshaft rotates, the engine will start.
