Exhaust brakes should not be used continuously for extended periods. Each use should be intermittent, with pauses of about 5 seconds, otherwise, it may damage the valves. Method of using the exhaust brake: 1. Move the lever backward to the first gear, activating engine braking in 4 cylinders, generating 66% of the engine braking power; 2. Then move the lever to the second gear, activating engine braking in 6 cylinders, achieving 100% engine braking power; 3. The exhaust brake is an auxiliary braking device used during prolonged downhill driving to assist the brakes by utilizing engine exhaust braking. The exhaust brake switch is located on the wiper lever and is widely used in large diesel vehicles. A regulating valve is installed on the engine exhaust pipe, and by closing this valve, the pressure in the exhaust stroke is increased, utilizing the generated negative pressure to obtain braking force.

Press the brake, shift gears, and hold for a few minutes or drive for a while, which can generally restore normal idle speed. Reasons for cleaning the throttle body: Over time, carbon deposits form at the throttle body opening, affecting the operation of the throttle plate, leading to engine stalling when not pressing the accelerator and unstable idle speed. The throttle body is a controllable valve that regulates air intake into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. The throttle body is connected to the air filter at the top and the engine block at the bottom, and is referred to as the throat of the car engine.
