What Causes the Burnt Smell When Accelerating Hard?
1 Answers
Reasons for the burnt smell when accelerating hard are: 1. Electrical system malfunction in the vehicle; 2. Severe brake pad wear generating heat and producing a burnt odor; 3. Aging of plastic pipes in the vehicle. The functions of the accelerator are: 1. Controlling the engine speed by adjusting the pedal pressure; 2. The accelerator regulates the carburetor to determine the engine's output power. The working principle of the accelerator is: Pressing the accelerator pedal directly controls the throttle valve, increasing its opening to allow more air into the engine. The ECU then commands the fuel injection system to increase fuel supply, raising the engine's RPM and thus accelerating the vehicle.
