What's the burning smell in the engine compartment?

There are six possible reasons for the burning smell in the engine compartment:

1. Poor starting coordination: It may be that the clutch of the starting throttle is not well matched, and the clutch plate smells burnt after high temperature.

Solution: After the running-in period, the smell disappears.

2. Engine Burnout: If the engine speed is too high, it is easy to burn out the engine. From a professional point of view, the larger the throttle opening, the higher the engine speed. The throttle of a gasoline engine controls the throttle opening, not the fuel injection quantity.

Solutions; Go to the 4s shop for repair.

3. Small throttle opening: If the throttle opening is small, less air will enter the cylinder, and the power generated by the engine will be small, and vice versa. The more air mixed into the cylinder, the greater the combustion force, so the greater the force to push the piston. The faster the piston moves, the faster the engine rotates.

Solution: Clean the throttle valve.

4. The anti-corrosion coating and oil stain on the external surface of the engine will give off a burnt smell when heated.

Solution: This situation is normal and does not need to be solved.

5. When the clutch is in semi-linkage state and the engine speed is too high, the clutch friction plate is excessively worn and will have a burnt smell.

Solution: Replace the clutch plate in time.

When the car suddenly accelerates, the tires idling on the ground will smell of burning. If you often leave tires idling on the ground, they will wear out faster.

Solution: Develop good driving habits and avoid sudden acceleration of oil supply. Million car purchase subsidy
