Where is the HOWO exhaust brake button located?

[DelMackenzie]

The HOWO exhaust brake switch is located on the left side of the clutch pedal. Exhaust brakes are widely used in large diesel vehicles, where a regulating valve is installed on the engine exhaust pipe. Closing this valve increases the pressure in the exhaust stroke, utilizing the generated negative pressure to obtain braking force. More related information is as follows: 1. Function of the exhaust brake: When going downhill, especially on long slopes, turning on the switch blocks the engine's exhaust, preventing it from expelling gases. Since the vehicle is in gear at this time, the engine acts to brake the wheels. 2. How the exhaust brake works in the engine: Most systems work by closing the engine's exhaust passage, causing the engine pistons to encounter gas backpressure during the exhaust stroke, thereby resisting engine operation and generating braking force to control vehicle speed. However, there are some restrictions: when using the exhaust brake, you must not shift to neutral or disengage the clutch, otherwise the exhaust brake will be ineffective and may lead to driving accidents.
