What does 'push' mean on a truck?
1 Answers
Truck's 'push' refers to the exhaust brake button. Here are the specific details about its meaning: 1. Introduction: Exhaust brakes are widely used in large diesel vehicles. A regulating valve is installed on the engine exhaust pipe, and the pressure during the exhaust stroke is increased by closing this valve, utilizing the generated negative pressure to obtain braking force. 2. Usage method: The exhaust brake is generally activated by a manual switch. To prevent engine stalling when stopping and to avoid exhaust brake operation during fuel injection, the exhaust brake is automatically released when the accelerator pedal or clutch pedal is pressed.
