Diesel engines typically operate at 50-150 RPM. Here are some usage precautions for diesel engines: 1. Engine oil: Diesel engines have different oil requirements compared to gasoline engines and require specialized engine oil. The oil change interval should preferably not exceed 6,000 kilometers. Additionally, it's essential to enhance the inspection and maintenance of three types of filters: the air filter, oil filter, and diesel filter. 2. Pay attention to RPM: When starting a diesel vehicle, avoid pressing the accelerator pedal, and don't start too quickly or operate at excessively high RPMs. After prolonged high-speed operation, do not shut down the engine immediately. Instead, let it idle for two to three minutes to allow the temperature to decrease before shutting it off to prevent heat accumulation.

Where is the antifreeze added

TRC being turned off does not affect driving, it only means that when wheel slippage occurs, the engine will not reduce power output, which may lead to wheel spin on slippery roads. As an auxiliary driving system, TRC helps to some extent with driving stability. Here is some information about TRC: 1. TRC stands for Traction Control System, also known as the Anti-Slip Regulation system, whose main function is to maintain vehicle stability. 2. The TRC system allows the vehicle to start or accelerate smoothly on wet or muddy roads, ensuring smooth acceleration. 3. If the car shows that TRC is off, turning the car off and then restarting it will automatically turn TRC back on, or you can press the button on the steering wheel to activate the TRC system.

Do You Need to Accelerate When Downshifting?

Downshifting does not require acceleration. Here are the details about downshifting: Downshifting Operation Introduction: When downshifting, release the accelerator pedal, quickly press the clutch pedal, shift the gear lever into neutral, then release the clutch pedal. Quickly tap the accelerator pedal with your right foot (adding "empty throttle"), press the clutch pedal again quickly, shift the gear lever into a lower gear, and release the clutch pedal following the fast-stop-slow technique to allow the car to continue driving in the new gear. Downshifting Timing Introduction: While driving, if you feel the engine lacks power and the speed gradually decreases, it indicates that the current gear can no longer maintain normal driving. You should promptly and quickly shift to a lower gear. If the speed drops significantly, you can skip a gear when downshifting.

What are the benefits of coated glass?

Coated glass offers benefits such as corrosion resistance, high temperature resistance, and easy cleaning. Below are detailed explanations: Corrosion Resistance: The hard non-organic (glass crystal) coating itself does not oxidize and also prevents external corrosive substances like acid rain, insects, and bird droppings from damaging the car paint. The dense glass crystal coating provides superior corrosion resistance, effectively protecting the car paint from damage caused by acidic substances and preventing color fading. High Temperature Resistance: The glass crystal itself has high temperature resistance properties, effectively reflecting sunlight and external heat radiation to prevent damage to the car paint from high temperatures. Easy Cleaning: The ion coating has excellent self-cleaning and water-repellent properties, making it less likely to accumulate dust and dirt. Cleaning can be done with just water, maintaining the vehicle's high cleanliness and gloss.

Is 16 Gauge Battery Jumper Cable Enough?

For small cars, a 16 gauge battery jumper cable is just sufficient. How to use jumper cables: Turn off the running vehicle, open the hood, attach the red jumper cable to the positive terminal of the battery, and the other end to the positive terminal of the dead battery. Attach the black negative cable to the negative terminal of the battery, and the other end to the negative terminal of the dead battery. Start the running vehicle, then start the dead vehicle. Once started, quickly remove the jumper cables from the battery. Precautions when using jumper cables: The order must not be mistaken: positive to positive, negative to negative. It can also be understood as red to positive, black to negative. A 12V vehicle cannot jump-start a 24V vehicle, and a 24V vehicle cannot jump-start a 12V vehicle.
