How often should the throttle body of a new car be cleaned?

It is recommended to clean the throttle body of a new car every 30,000 kilometers. If the driving environment is harsh, the cleaning interval should be shortened. Method for cleaning the throttle body: If there is a plastic heat shield on the engine, remove it. Then disconnect the air ducts around the throttle body and note their positions. Typically, the side of the throttle body closer to the combustion chamber tends to be dirtier, with black carbon deposits being the main area to clean. Special cleaning solutions or carburetor cleaners can be used, but these chemicals can be harmful to humans, so wear gloves and a mask during cleaning. Spray the cleaner onto the areas with heavy carbon deposits on the throttle body and wait 5-10 minutes. Once the carbon deposits dissolve, wipe them off with a cloth. After cleaning, reinstall the throttle body in its original position and reconnect all air ducts.

What are the precautions when inflating car tires?

Precautions when inflating car tires include: 1. Pay attention to safety during inflation and always use a pressure gauge to check the air pressure to avoid tire bursting due to over-inflation; 2. After stopping the vehicle, wait for the tires to cool down before inflating, as tire temperature rises during driving, which affects air pressure; 3. Check the valve stem. If the valve stem and valve core do not fit smoothly, with protrusions, depressions, or other defects, it will be inconvenient for inflation and pressure measurement; 4. Ensure cleanliness during inflation. The air being pumped in should not contain moisture or oil to prevent deterioration and damage to the inner tube rubber; 5. Do not exceed the standard air pressure excessively and then deflate, nor should you over-inflate due to prolonged inability to inflate while traveling. Excessive over-inflation can cause excessive stretching of the cord, leading to a reduction in its strength.

What are the reasons for the Cruze's lack of power when climbing slopes?

Faults that cause lack of power when climbing slopes include: engine faults (carbon deposits), engine intake system faults, and engine fuel system faults. Below are detailed explanations: 1. Carbon deposits in the engine: The most common is spark plug carbon deposits, which affect the stability of the ignition system, leading to incomplete fuel combustion, increased fuel consumption, and other issues, thereby causing the car's power to weaken and lack strength when climbing slopes. 2. Blockage in the car's intake or exhaust system: This could be due to a clogged air filter or a blocked three-way catalytic converter in the exhaust pipe, affecting the car's exhaust flow, which in turn prevents the engine from working properly, reducing the car's power. 3. Engine fuel system fault: Possible causes include clogged fuel injectors, fuel leaks, aging fuel pumps affecting the engine's power reduction, or a clogged engine oil filter, preventing the engine from functioning properly and causing abnormal vehicle power.

What is the general height of a car?

The height of a car is generally between 1400mm and 1600mm, with lengths ranging from 3800mm to 4300mm and widths between 1600mm and 1800mm. The length, width, and height of a car refer to the outermost dimensions of the vehicle. The front and rear lengths include the length of the bumpers, the width does not include the dimensions of the side mirrors (if the manufacturer provides multiple width measurements, the one excluding the side mirrors is added; if only one measurement is provided, that data is used), and the height includes the roof rack but not the antenna. Specific meanings of car dimensions: Car length refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane, touching the outermost protruding parts at the front and rear of the car. Car width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane, touching the fixed protruding parts on both sides of the vehicle (excluding side mirrors, marker lights, position lights, turn signals, flexible mudguards, folding steps, anti-skid chains, and the part of the tire in contact with the ground). Car height refers to the distance between the vehicle's supporting plane and the horizontal plane touching the highest protruding part of the vehicle. Practical significance of car height: The height of the car body determines its center of gravity and interior space. Most small cars are below 1.5 meters in height, which is much lower than the natural sitting height of a person, sacrificing a lot of headroom for passengers. This is mainly to lower the vehicle's center of gravity, ensuring stability during high-speed turns to prevent rollover. MPVs and small trucks, designed for spacious headroom and cargo space, typically have a height above 1.6 meters. However, this raises the vehicle's center of gravity, making it more prone to rollover during high-speed turns—a significant drawback of taller vehicles. Additionally, most indoor parking lots have height restrictions, usually around 1.6 meters, which imposes certain limitations on taller vehicles.
