To use the exhaust brake in a vehicle: 1. Move the lever backward to the 1st gear, which activates engine braking in 4 cylinders, generating 66% of the engine braking power; 2. Shift to the 2nd gear to activate engine braking in all 6 cylinders, achieving 100% engine braking power; 3. The exhaust brake is an auxiliary braking device used during prolonged downhill driving to assist with braking through engine exhaust braking. The exhaust brake switch is located on the wiper control and is widely used in large diesel vehicles. A regulating valve is installed on the engine exhaust pipe, and closing this valve increases the pressure in the exhaust stroke, utilizing the generated negative pressure to obtain braking force.

What is the difference between nitrogen and air in car tires?

Tire pressure is more stable when filled with nitrogen compared to air. There are three advantages to filling tires with nitrogen: 1. Nitrogen has low sound transmission, which can reduce noise: it minimizes vibrations, making driving more comfortable and quiet; 2. Improves the shock absorption elasticity of the tire: enhances the tire's grip during turns, acceleration, or braking, improving adhesion to the road and making driving more controllable; 3. Nitrogen contains no oxygen, delaying the aging of tire rubber: it is free of water and oil, slows down rubber aging, extends tire lifespan, and reduces oxidation corrosion on the wheel hubs.
