Does Idling Consume More Fuel?
1 Answers
Vehicle idling does consume more fuel. The following are the reasons related to idling: 1. The air intake of the car is affected: During idling, the air intake of the car is affected. At this time, the car cannot inhale enough air for fuel combustion. In this state, the energy released by incomplete combustion of gasoline is far less than the heat generated when the car has sufficient air intake. However, the engine still needs to provide the energy required for the normal operation of various parts of the vehicle, so more gasoline is consumed. 2. Torque and fuel injection increase: During idling, the engine must be ready to respond to the driver's starting operation. When starting the car, it changes from a stationary state to a moving state, so the engine needs to exert greater torque than during normal driving. The amount of fuel injected by the fuel injector will be slightly more than during normal driving. Additionally, the engine speed increases during starting, which also increases fuel consumption.
