Is it normal for the engine to knock at idle but stop when the throttle is applied?

It is not normal for the engine to knock at idle but stop when the throttle is applied. Causes of this phenomenon: During cold starts, there may be insufficient lubrication between the piston and cylinder wall, excessive clearance between the piston and cylinder wall, or excessive cylindricity of the piston. This causes the piston to swing and strike the cylinder wall under high-pressure gas during the power stroke, resulting in a metallic knocking sound. Hazards of engine idling: When the engine is idling, the lower temperature and pressure inside the cylinder prolong the ignition preparation time. Combined with reduced cylinder sealing, this makes knocking more likely, shortening the engine's service life.

What does EPB malfunction mean?

EPB stands for Electrical-Park-Brake in English, which is the electronic parking brake system. An EPB malfunction means there is a fault with the electronic handbrake. Here is some extended information: 1. Function of EPB: EPB controls the parking brake through electronic circuits, serving the same purpose as a mechanical lever handbrake. When starting the vehicle, there's no need to manually release the electronic handbrake; it will automatically disengage when you press the accelerator. 2. Causes of malfunction: An electronic handbrake malfunction could be due to faults in components such as wheel speed sensors, throttle position sensors, handbrake switches, wheel speed sensors, motors, etc. Any abnormality in these components could cause the EPB light to illuminate.

What does transmission fluid WS mean?

Transmission fluid WS is a specific model of oil, exclusively used by Toyota. Its viscosity, lubrication performance, and heat dissipation performance are all matched. Using other oils may cause problems with the transmission. Hazards of not replacing transmission fluid: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Affects the normal operation of the transmission, leading to damage to the transmission valve body. Transmission fluid is different from engine oil. Although both oils serve a lubricating function, their effects are different and should not be confused. Differences: Engine oil is the lubricating oil for the engine system, possessing certain properties such as oxidation resistance, anti-wear, and anti-corrosion. Transmission fluid, on the other hand, is mainly used to keep the gear system clean and extend the service life of internal transmission components. Because the structure and operating environment of the transmission and the engine are different, transmission fluid cannot be used as engine oil, nor can engine oil be used as transmission fluid.

How to Remove Dried Automotive Spray Paint?

Paint thinner can be used to clean spray paint. Apply the thinner to the paint, wait for it to soak in, then rinse with water to remove the paint. For larger areas, improper handling can easily damage the car paint, causing scratches, fading, discoloration, or a matte finish. It is recommended to visit a professional automotive detailing center for paint surface treatment. Additional information about automotive painting is as follows: 1. Introduction: Automotive painting involves applying a layer of paint to the car's surface to protect it. Baking paint is commonly used for automotive painting. In automobile manufacturing plants, after the frame and body are welded, the next step is painting. Types include standard paint, metallic paint, and pearl paint. The automotive painting process includes applying putty, sanding, and painting. 2. Composition: Automotive paint generally consists of four basic components: film-forming substances (resins), pigments (including extender pigments), solvents, and additives.

Will electric cars short circuit when driving through water?

Most of the abnormal noises when the car is bumpy are due to the aging and hardening of the shock absorber top rubber. There is rubber where the vehicle's shock absorber connects to the body, and this rubber is called the shock absorber top rubber. The function of this rubber is to provide cushioning for the body and reduce vibrations. Over time, the rubber will age, and aged rubber will harden, so when driving over some bumpy roads, abnormal noises will come from the body. Additional information is as follows: 1. Antifreeze usage tips: It is best to use antifreeze all year round. In addition to its anti-freeze and cooling functions, antifreeze also has cleaning, rust removal, and anti-corrosion effects, reducing corrosion of the radiator and protecting the engine. Pay attention to choosing the correct color of antifreeze and do not mix different types. 2. Brake fluid usage tips: The function of the brake system is closely related to the brake fluid. When checking or replacing brake pads, brake discs, and other hardware, do not forget to check whether the brake fluid needs to be added or replaced.

How to Read the Fuel Gauge in a Cadillac?

In the Cadillac dashboard's driver information center, you can check the fuel tank status. On the left side of the display screen, within the tachometer information panel, you can view the fuel level information. A reading of 1 indicates a full tank, while 0 signifies an empty tank. Additional Information: 1. Introduction to the Fuel Tank: A container for storing fuel in aircraft or automobiles, it is a specialized vessel in hydraulic systems for storing hydraulic oil or fluid. Fuel tanks can be categorized into open-type and closed-type tanks. 2. Purpose of the Fuel Tank: In hydraulic systems, besides storing oil, the fuel tank also functions to dissipate heat, separate air bubbles from the oil, and settle impurities. The tank is equipped with various accessories such as coolers, heaters, air filters, and liquid level gauges.
