There are many reasons for the unstable idling speed of Wuling Hongguang. Excessive Carbon Deposits: Dirt from the air and sludge from gasoline can easily cause the vehicle's throttle to become dirty, leading to poor operation of the idle speed control valve. Excessive carbon deposits can result in incomplete valve sealing, poor fuel injector atomization, and insufficient combustion. Other Reasons: Exhaust pipe blockage, leading to poor exhaust flow, or air leakage causing insufficient vacuum. Aging wiring or issues with the ECU—these phenomena are unlikely to occur in the short term, so it is recommended that owners avoid installing additional devices on the vehicle. Insufficient cylinder pressure or natural wear—these phenomena also do not occur in the short term.

What Causes the Shaking When Releasing the Accelerator?

The shaking when releasing the accelerator is caused by: mismatched engine and transmission, clutch issues, or gaps created by loose ball joints in the steering linkage. Precautions when pressing the accelerator include: 1. Press and release the accelerator pedal gently and smoothly; 2. Coordinate the release of the clutch with pressing the accelerator promptly and precisely; 3. Select the appropriate gear to keep the engine running mostly at medium speed and with a larger throttle opening to save fuel; 4. Before stopping or turning off the engine, release the accelerator pedal first and avoid revving the engine abruptly. The working principle of the accelerator is: pressing the accelerator pedal directly controls the throttle, increasing the throttle opening, which allows more air into the engine. The ECU then commands the fuel injection system to inject more fuel, increasing the engine's RPM and accelerating the vehicle.

What is the working principle of a car handbrake?

Car handbrake works as follows: Brake disc transmission tension: For small cars, some handbrakes are located behind the transmission, connected to the driveshaft with a brake disc, similar to a disc brake (though some use drum brakes). The tension is transmitted through steel cables to achieve parking braking. Hydraulic auxiliary cylinder drives air valve: When the handbrake is pulled, it uses a hydraulic auxiliary cylinder to push the main hydraulic cylinder beneath the car, which then drives the air valve. After the air valve moves, it brakes the driveshaft. Electronically controlled handbrake: High-end cars use electronic control. When the handbrake is engaged, an electric traction motor activates, tightening the steel cable and locking it after the air brake is completed.
