What are the effects of pressing the accelerator while depressing the clutch?
1 Answers
When the clutch pedal is fully depressed, the engine and transmission are disconnected. At this time, pressing the accelerator will cause the engine to idle. If the clutch pedal is not fully depressed and the clutch is not completely disengaged, pressing the accelerator pedal will cause the car to lurch forward and accelerate the wear of the clutch plates. Although engine idling does not cause immediate damage, frequent idling can lead to carbon buildup in the vehicle, which is harmful to the engine's intake and exhaust systems. Carbon deposits can block the idle channel, causing the idle control device to stick or exceed its adjustment range. This can result in low idle speed, idle shaking, failure of various auxiliary devices to accelerate, stalling when releasing the throttle, excessive exhaust emissions, and increased fuel consumption. Purpose of revving the engine without load: In cold winter weather, the atomization effect of the fuel injectors may be poor, making it difficult for some low-end cars to start. Revving the engine without load can help start the car by increasing the fuel injection volume, making it easier to ignite. However, repeatedly revving the engine too quickly can flood the spark plugs, making it impossible to start the vehicle.
