What does engine traction mean?
3 Answers
Engine traction refers to the force generated by the engine through the transmission system applying torque to the wheels, which then interacts with the ground through the driving wheels. The direction of this force is the same as the direction of the vehicle's movement. Definition of engine: The car engine is the device that provides power to the vehicle, serving as the heart of the car. It determines the vehicle's power, fuel efficiency, stability, and environmental performance. Depending on the power source, car engines can be classified into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid systems, among others. Precautions for engine maintenance: Regularly maintain the engine by servicing it according to the recommended schedule and mileage, and use the appropriate engine oil. Keep the coolant clean to ensure good heat dissipation for the engine. Periodically clean the engine's fuel and air intake systems to ensure smooth fuel and air intake channels.
Engine braking is the use of the engine's own resistance to help slow down the vehicle. For example, when going downhill, shifting to a lower gear allows the car to slow down steadily without heavy use of the brakes. This is because the movement of the pistons inside the engine creates resistance, which is transmitted to the wheels through the drivetrain. I particularly love using this technique when driving on mountain roads, especially during long descents. I've seen brake pads overheat and glow red too many times. Using engine braking not only protects the braking system but also makes the ride smoother for passengers. I remember once driving an automatic car down a steep slope—I simply switched to manual mode and shifted to second gear, and the speed was perfectly controlled. This technique is incredibly useful for improving driving safety.
Simply put, when the engine is not receiving fuel, it actually becomes a decelerator for the vehicle. The principle is similar to how, when coasting downhill on a bicycle without pedaling, the chain pulls on the rear wheel to slow it down. When driving, releasing the throttle to coast or downshifting in a manual transmission causes the engine's compression resistance to be transmitted through the transmission to the wheels. I've found this deceleration method to be exceptionally smooth, preventing passengers from lurching forward or backward. Especially on slippery roads during rain or snow, sudden braking can easily cause skidding, whereas relying on engine braking for deceleration is safer. Moreover, many modern automatic transmission models can achieve the same effect by using paddle shifters to downshift.
