[JosephineLee]

HOWO Exhaust Brake Switch The symbol for the HOWO exhaust brake switch is a valve in the middle of a pipeline, located to the left of the clutch pedal. Additional Information: 1. HOWO: HOWO is China's most advanced and premium new-generation heavy-duty truck developed by Sinotruk Group in 2004. It incorporates key global heavy truck technologies, targets both domestic and international markets, and aligns with international technical standards while possessing independent brand and intellectual property rights. 2. Exhaust Brake: Exhaust brakes are widely used in large diesel vehicles. A regulating valve is installed on the engine exhaust pipe. Closing this valve increases the pressure during the exhaust stroke, utilizing the generated negative pressure to obtain braking force. The regulating valve is generally driven by a control mechanism using compressed air or vacuum, often sharing the same power source as the main brake. The exhaust brake is typically activated by a manual switch. To prevent engine stalling when stopping and to avoid exhaust brake operation during fuel injection, the exhaust brake automatically disengages when the accelerator or clutch pedal is pressed.
