Why does the tachometer not move when stepping on the accelerator?

What is valve clearance?

Valve clearance refers to the gap between the valve and its transmission components when the engine is in a cooled state and the valve is closed. Below is an extended introduction: 1. When the valve clearance is too large: The intake and exhaust valves will open late, resulting in insufficient air intake and incomplete exhaust, leading to a decrease in power. It also increases the impact on the valve train components, accelerating wear and increasing noise. 2. When the valve clearance is too small: As the engine operates and the temperature rises, component expansion can cause gas leakage, naturally reducing power. Over time, carbon deposits may form on the sealing surfaces, and in severe cases, the valves may collide with the pistons.

Does Low Washer Fluid Affect Driving?

Low washer fluid does not have a significant impact on driving, but insufficient car washer fluid may affect driving safety. In dusty environments or when driving on highways during rain, if the windshield becomes blurry and there is no washer fluid, using the wipers alone will not clean the windshield effectively, posing a major safety hazard. Additional Information: Below are some details about washer fluid: 1. Regular Checks: In dusty environments or when driving on highways during rain, washer fluid is consumed very quickly. It is safest to perform regular checks and keep spare washer fluid in the car for easy refilling when needed. 2. Refilling Notes: Car washer fluid is a consumable item in vehicle use. If you run out, you can purchase and refill it yourself or visit a 4S shop or repair shop for assistance. Avoid using plain water directly, as it can damage the wipers and glass. 3. Consequences of No Washer Fluid: Continuously operating the washer fluid lever without fluid can cause the motor to overheat, leading to expensive repair costs.

What Causes Air Brake Failure?

Reasons for air brake failure include insufficient air pressure in the braking system, suggesting inspection of pipelines and the air pressure pump; it may also be due to excessive brake clearance, recommending adjustment of brake pad clearance. Below is relevant content introduction: 1. Parking Brake: Conventional parking brakes lock the drive shaft, while foot brakes use compressed air entering the brake chamber to lock the wheels. The parking brake fails when there is a mechanical fault in the parking brake or drive shaft; the foot brake fails when there is a fault in any part of the air pump, pipeline, air reservoir, or brake valve. The air break brake can effectively avoid these dangers. 2. Before Starting: Before starting the vehicle, the control lever of the manual valve should be moved back to the position that releases the parking brake, allowing compressed air from the parking brake air reservoir to fill the parking brake chamber.

Will There Be a Jerking Sensation When Accelerating and Decelerating at Low Speeds?

There is a jerking sensation when accelerating and decelerating at low speeds. Below are detailed explanations: 1. Reasons: Clean engine carbon deposits, check the oxygen sensor, and regularly replace the three filters. 2. Content: When driving at low speeds, the jerking sensation is noticeable during acceleration and deceleration. Cleaning engine carbon deposits is essential; excessive carbon buildup can be addressed by adding a certain amount of cleaner during refueling and driving at high speeds for a period, which helps increase exhaust flow and carry away carbon particles. Checking the oxygen sensor is crucial as it monitors the air-fuel ratio in the engine. A damaged oxygen sensor can disrupt the air-fuel ratio, leading to a sudden increase in fuel consumption. If the oxygen sensor is faulty, the vehicle will emit darker exhaust gases from the tailpipe during driving, indicating the need for replacement.
