How to Avoid Stalling and Rolling Back on the Slope Start in Subject 2?
2 Answers
Here are the methods to avoid stalling and rolling back on the slope start in Subject 2: 1. Do not suddenly release the clutch when stepping on the accelerator; lift the clutch slowly, as doing it too quickly can easily cause stalling. 2. Tighten the handbrake and release it slowly. 3. Press the foot brake all the way down to maintain sufficient braking force. 4. Use the clutch's semi-engaged state to overcome the resistance of the downhill slope. Here is additional information on the causes of engine stalling: 1. Abnormal resistance of the crankshaft position sensor can cause the crankshaft speed signal to disappear after the engine heats up, leading to stalling. 2. Prolonged operation of the fuel pump can change its resistance, preventing it from providing normal fuel pressure and causing the engine to stall. 3. Ignition system failure or overheating of the ignition module can prevent normal operation and cause the engine to stall. 4. Abnormal throttle signal voltage can cause the engine to stall while driving. 5. Loose wiring can cause intermittent engine stalling.
To avoid stalling or rolling back during the hill start in Subject 2, I believe the key lies in coordinating movements. As a coach who frequently instructs students, I would recommend breaking it down into steps: First, press the clutch pedal all the way down, shift into first gear, and gently press the accelerator to raise the engine speed to around 1,500 RPM. Then, slowly release the clutch to the biting point, where you'll feel a slight vibration in the car body, indicating the engine is preparing to engage. Next, as you release the handbrake, continue smoothly releasing the clutch while slightly increasing the accelerator. The coordination between hands and feet should be like dancing—don't rush. If the clutch is released too quickly, the engine may stall; if the accelerator isn't sufficient, the car may roll back. Start practicing on a gentle slope to get familiar with the feeling before tackling steeper ones. Remember, keep the car's nose pointed straight uphill and avoid distractions like checking the dashboard, as this will help you master the technique faster.
