What is the reason for the engine stalling when the clutch is fully depressed?

The reasons for the engine stalling when the clutch is fully depressed are: 1. The fuel supply pipe is compressed when the clutch is fully depressed; 2. The throttle body is excessively dirty; 3. Malfunction in the computer system; 4. Damage to the clutch cable or clutch disc. The working principle of the clutch is: 1. When the inner race is fixed, the outer race can rotate freely in the clockwise direction as the wedge block does not lock; 2. When the outer race rotates counterclockwise, the wedge block locks, preventing the outer race from rotating. The functions of the clutch are: 1. Gradually increasing the driving force of the car to ensure a smooth start; 2. Temporarily separating the engine and transmission for gear shifting; 3. Preventing overload in the transmission system; 4. Reducing torsional vibration impacts from the engine and extending the lifespan of transmission gears.
When I was learning to drive, stalling the manual transmission car by fully depressing the clutch pedal was terrifying. This usually happens because the clutch switch is faulty and can't detect pedal position, causing signal interruption; or the sensor is covered in oil and dust, interfering with transmission; a stuck idle control valve can also cause unstable engine shutdown. I remember during my first parallel parking attempt, the car would stall if I pressed the pedal slightly harder - so embarrassing. Later inspection revealed it was caused by switch corrosion. I recommend beginners regularly keep the pedal area clean to avoid debris accumulation - safe driving is what matters most. If this happens on the road, immediately turn on hazard lights and pull over, never force a restart.
