What Causes the Failure of the Car Power Steering System?

If the power steering system warning light is on, it may be due to a malfunction in the steering system sensor, steering gear, or power steering pump. It could also be caused by a lack of medium in the vehicle's power steering system, leading to mechanical assistance failure, which can be resolved by replacing the internal power steering fluid. Below is a detailed introduction to the car power steering system: 1. Function: It utilizes the power generated by an electric motor to assist the driver in steering. This system directly provides steering assistance through an electric power steering motor, eliminating the need for components such as the power steering oil pump, hoses, hydraulic oil, transmission belt, and pulley mounted on the engine, saving energy and protecting the environment. 2. Composition: The car power steering system can improve vehicle stability. When the vehicle shows signs of instability, the electronic power steering system can independently brake each wheel and participate in the engine system management to ensure driving safety. The car power steering system mainly consists of a speed sensor, reduction mechanism, torque sensor, electric motor, and electronic control unit.

What is the general capacity of a windshield washer fluid reservoir?

Generally, a windshield washer fluid reservoir holds about 4.5 liters. However, the filling capacity varies depending on the vehicle model. For ordinary sedans, adding 2 liters is usually sufficient. The method to add windshield washer fluid is as follows: 1. Turn on the wiper switch to spray the fluid onto the windshield; 2. Open the washer fluid filler cap and add a small amount of fluid; 3. Turn on the wiper switch to clean the remaining fluid; 4. When no more fluid sprays out from the nozzles during the second attempt, add more washer fluid. The functions of windshield washer fluid include: 1. Cleaning debris off the windshield; 2. Lowering the freezing point of the liquid; 3. Ensuring the windshield remains clear and transparent for good visibility; 4. Eliminating static charges on the glass surface; 5. Reducing friction between the wipers and the glass to prevent scratches.

Is it normal to have a speed of 120 km/h with an engine speed of 3500 rpm?

A speed of 120 km/h with an engine speed of 3500 rpm is not normal; this rpm is relatively high. Generally, most cars maintain an engine speed of around 2000 rpm at 120 km/h. When driving at high speeds, the transmission is usually in a high gear, which helps reduce engine speed and save fuel. Engine speed constantly reflects the working condition of the engine. If the speed is too low, fuel combustion in the cylinders may be incomplete, leading to carbon buildup in the engine, which can cause significant damage over time. Conversely, if the speed is too high, it can result in greater engine wear. Engine speed refers to the number of revolutions an object makes around a circular path per unit of time (different from frequency), with common types including rated speed and maximum speed.

What Causes the Clanking Noise During Cold Start?

Cold start clanking noise can be attributed to the following reasons: 1. If there is a clicking sound within the first half minute that disappears afterward, this is usually caused by the expansion of the catalytic converter as it heats up, which is normal; 2. A loud clicking noise during cold start is mostly due to issues with the engine's timing system, such as wear, elongation, or loosening of the timing belt or chain, or the failure of the chain tensioner to maintain proper tension; 3. If the noise occurs only when the air conditioning is turned on, it may be due to friction in the air conditioning belt; 4. If the noise is present only during the initial moment of cold start, it could be a fault in the starter motor, primarily caused by poor return of the starter gear, inadequate lubrication of the one-way clutch, or slow return of the gear being dragged back by the flywheel. This phenomenon is more common in winter.
