What is the actual lifespan of the X-Trail CVT transmission?

Under normal circumstances, the lifespan of the X-Trail CVT transmission can exceed 100,000 kilometers. Function of the transmission: The transmission is a mechanism used to alter the speed and torque from the engine. It can fix or change the gear ratio between the output and input shafts in steps, hence also known as a gearbox. The transmission consists of a gear transmission mechanism and a control mechanism, with some vehicles also featuring a power output mechanism. Most transmission mechanisms use ordinary gear transmission, while some employ planetary gear transmission. Ordinary gear transmission mechanisms typically use sliding gears and synchronizers, among others. Transmission maintenance knowledge: Understand the replacement cycle for automatic transmission fluid. For most automatic transmissions, the fluid replacement cycle is generally every two years or 40,000 to 60,000 kilometers. It is recommended to replace the fluid 2,000 to 3,000 kilometers in advance. Correctly replace the transmission fluid. The better method for fluid replacement is dynamic replacement, using specialized transmission fluid replacement equipment. During the operation of the transmission, the old fluid is thoroughly circulated and completely drained before adding new transmission fluid, achieving a replacement rate of over 90% and ensuring a good replacement effect.

What is the fuel tank capacity of the BAIC E130?

The fuel tank capacity of the BAIC E130 is 56 liters. In terms of power, it is equipped with a 4A90M 1.3L inline four-cylinder gasoline engine, delivering a maximum horsepower of 99hp at 6000rpm and a peak torque of 12.8kgm at 4000rpm. Maintenance for the fuel tank is as follows: Drain accumulated water and sediment from the tank, and check for any oil leaks at the fuel pipe joints and switches. For fuel tank caps equipped with air valves and vapor valves, also ensure the vent holes are clear. The filter screen at the fuel filler neck should remain intact to prevent impurities from entering the tank during refueling and clogging the fuel lines. The sealing gasket on the fuel filler cap should also be in good condition to prevent fuel spillage while driving. To check the remaining fuel level, observe the fuel gauge on the right side of the instrument panel, marked with 'E' and 'F'. When the needle is near 'E', it indicates low fuel, while near 'F' means sufficient fuel. Methods to open the fuel tank: Mechanical key opening: Commonly found in rugged off-road vehicles, this method is rarely used in modern family cars. In-car switch method: The location of the in-car fuel tank switch varies by model. Remember to turn off the engine before refueling. Press-to-open method: The press-to-open fuel tank door is currently the most convenient method.
