Car tire codes indicate the following: Taking 225/60R17 99H as an example, 225 represents the section width, which is the width of the tire tread; 60 represents the aspect ratio, which is the height of the tire sidewall; R stands for the tire type code, with R indicating a radial tire; 17 represents the rim diameter, meaning the tire is suitable for 17-inch rims. 99 represents the load index of the tire, indicating the maximum weight the tire can bear; H stands for the speed rating, which is the maximum speed the tire can handle. Car tires are one of the essential components of a vehicle, directly in contact with the road surface. Together with the car suspension, they help absorb shocks during driving, ensuring good ride comfort and smooth driving performance.

How much oil should be added to the Mercedes-Benz 275 engine?

Recommended 6-7 liters of engine oil. Introduction to engine oil: Engine oil, also known as engine lubricant (English name: Engine oil), plays multiple roles such as lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricants, determining their fundamental properties, while additives compensate for and enhance the performance shortcomings of the base oil, providing certain new characteristics, making them an essential part of lubricants. Preventive measures against oil burning: Use high-quality engine oil. Under prolonged high-temperature conditions, engine oil is highly susceptible to corrosion and aging, leading to thinning of the oil film and making it easier to seep into the combustion chamber and participate in combustion. Therefore, using high-quality engine oil can significantly delay this phenomenon. Pay attention to the cleanliness of the fuel system. During the combustion process, fuel inevitably produces carbon deposits, which are the root cause of various automotive malfunctions.

Why Does a Manual Transmission Car Jerk During Acceleration?

During gear changes in the transmission, the engine speed undergoes variations. If the transmission fails to handle this process smoothly, causing abrupt changes in engine RPM during shifting, the inertia of the engine operation will react against the vehicle. This leads to sudden changes in vehicle speed, resulting in a jerking sensation. Manual transmissions are particularly prone to jerking during rapid acceleration, with the severity increasing the deeper the throttle is pressed. If jerking occurs during sudden acceleration when it previously didn't or was minimal, this may indicate a vehicle malfunction. Lower gears exhibit higher torque multiplication ratios but also more pronounced jerking. Wider gear ratio spacing between gears creates larger RPM differences during shifts, making jerking more noticeable. Potential causes for sudden jerking during acceleration include: 1. Faulty spark plugs or ignition coils - Worn spark plugs that haven't been replaced timely can reduce ignition efficiency or cause misfires. 2. Excessive carbon buildup - Long-term accumulation on throttle bodies, fuel injectors, and intake passages can reduce engine power. 3. Substandard fuel quality - Poor combustion in the engine affects performance. 4. Contaminated transmission - Manual transmission fluid should be changed every 60,000 km; dirty internal components can disrupt oil pressure, leading to jerking.

Can the Clutch and Brake Be Pressed Simultaneously in a Manual Transmission?

Theoretically, the brake and clutch can be pressed together, but pressing the clutch is equivalent to shifting into neutral. Without gear engagement, the braking distance of the car will be extended, which can easily lead to safety hazards. Especially during emergency braking, pressing both the brake and clutch in a manual transmission is more likely to cause a rear-end collision. Correct Approach: During normal driving, try to avoid pressing the brake and clutch simultaneously. The correct method is to press the brake first and then press the clutch when downshifting is required. Starting with the Brake: Foot Brake Start: With the foot brake pressed, depress the clutch, shift into first gear, and release the clutch to the semi-engagement point. When the body slightly vibrates and the front of the car lifts, release the foot brake, and the vehicle will start moving slowly. Hand Brake Start: When starting with the hand brake, there is no need to press the foot brake. This method is used on slopes where the hand brake is engaged to stabilize the parked car. The specific steps are: hold the steering wheel firmly with the left hand, depress the clutch, shift into first gear, place the right hand on the hand brake, release the clutch to the semi-engagement point, and immediately release the hand brake to allow the vehicle to move forward smoothly.
