Does the Auto Start-Stop Function Harm the Engine?

Auto start-stop function has a certain impact on the engine, but the impact is very minimal and does not affect the engine's service life. When car manufacturers produce engines with auto start-stop, the designed lifespan of the auto start-stop function is 500,000 cycles. Even if it starts 100 times a day, it would take about 17 to 18 years to reach that limit. The real significant impact on the engine occurs during cold starts, when the oil circuit and engine oil are circulating. Auto start-stop involves hot starts, where the engine already has oil lubrication. Therefore, even frequent start-stops cause minimal wear to the engine. The start-stop function only stops the engine from working, but the oil system continues to operate, ensuring better lubrication when the car starts again, which also helps protect the engine.

Solutions for being afraid to drive after buying a car are as follows: 1. Familiarize yourself with various buttons: This helps you know what to do in emergency situations while driving and reduces fear of the vehicle. 2. Drive familiar routes: Taking routes you know well can alleviate fear. 3. Stick to the same car: It's best to use the same car when you're just starting out. Precautions for novice drivers include: 1. Carry necessary documents: Always have your driver's license, vehicle registration, ID card, etc., to avoid being mistaken for driving without a license. 2. Know traffic rules: Deepen your understanding of traffic regulations to avoid last-minute decisions at intersections about turning right or making U-turns.

How to Drive Better During the Break-in Period?

Better driving techniques for beginners during the break-in period are as follows: 1. Avoid overloading: The load capacity of the car during the break-in period should not exceed 75% of the rated load. New cars should be loaded below the specified weight and number of passengers, and must not be overloaded. 2. Do not drive at high speeds: There are speed limits for new cars during the break-in period. Domestic cars should stay within 40~70 km/h, while imported cars generally should not exceed 100 km/h. 3. Use high-quality gasoline: The gasoline used for new cars during the break-in period should not be lower than the octane rating specified by the manufacturer. Do not add anti-wear oil additives to avoid insufficient break-in despite reaching the required mileage.

What is the difference between with T and without T?

There are the following differences between with T and without T: 1. With T: A car with T refers to the engine using turbocharging, where T stands for "TurboBoost", meaning turbocharging. Turbocharging utilizes the high-speed exhaust gas from the engine to drive the turbine, increasing the intake pressure, thereby increasing the intake air volume, making the fuel-air mixture burn more completely, and significantly improving the engine's power and torque, achieving exhaust gas reuse. 2. Without T: Without T means the car uses a naturally aspirated engine. A naturally aspirated engine only uses the negative pressure formed by the piston's downward movement to draw air into the cylinder and combustion chamber, while the exhaust gas is directly discharged without reuse. For engines of the same displacement, the naturally aspirated engine has a smaller intake air volume, and its power and torque are also lower.

What is the actual fuel consumption of the Foton Cummins 3.8?

Foton Cummins 3.8 fuel consumption is around 16 liters. The reasons for the high fuel consumption of Cummins engines are as follows: Insufficient tire pressure: If the tire pressure is insufficient, fuel consumption will increase; if the tire pressure is normal, you can check the degree of tire wear. When the tires are severely worn, slipping often occurs, which also increases fuel consumption. Excessive carbon deposits: This can lead to higher fuel consumption in the car, which is likely caused by the use of substandard fuel. Oxygen sensor failure: The oxygen sensor mainly monitors the air-fuel ratio of the engine. Once it is damaged, it will cause an imbalance in the engine's air-fuel ratio, inevitably leading to abnormally high fuel consumption.
