The reasons why a car's RPM increases but the speed doesn't go up are: 1. Burning of clutch discs; 2. Insufficient tightening torque of the friction plate clutch; 3. Transmission oil hasn't been changed for too long or damage to the hydraulic mechanism in the transmission; 4. Slippage of internal friction plates in the transmission; 5. Failure in the engine's electronic control system. Car RPM refers to the rotational speed of the car's engine. The car's tachometer is located on the instrument panel, symmetrically placed with the speedometer. Its functions are: 1. To promptly reflect the operating condition of the engine; 2. To allow the driver to better coordinate the transmission gear and throttle position; 3. To keep the car in a better working state; 4. To reduce consumption and prolong the engine's lifespan.

How often should the carbon canister in a sedan be replaced?

The carbon canister in a sedan is not a wear-and-tear part and does not have a fixed replacement interval. If the car exhibits symptoms such as jerking, increased fuel consumption, or a gasoline smell, and troubleshooting proves ineffective, it is necessary to check whether the carbon canister needs replacement. When gasoline in the fuel tank produces vapor, releasing it directly into the air would cause environmental pollution. Therefore, the carbon canister stores these vapors and introduces them into the engine cylinders for combustion under appropriate operating conditions. The carbon canister is typically installed between the fuel tank and the engine. Since gasoline is a volatile liquid, the fuel tank often contains vapor at normal temperatures. The fuel evaporation emission control system is designed to direct these vapors into the combustion process and prevent them from evaporating into the atmosphere.
