Car Exhaust Vent Engine Energy

Car vent failure analysis: When the copper wire of the low-voltage wire of the distributor is broken, the cross-sectional area of the wire is reduced, which increases the resistance of the primary circuit and reduces the current in the circuit, resulting in insufficient high voltage generated by the ignition coil. When the engine temperature is low, although starting is more difficult, the engine can run normally after starting.

After the engine temperature rises, the temperature of the ignition coil increases, and the resistance increases with the increase in temperature. Therefore, the high-voltage electricity generated by the ignition coil will be insufficient, the high-voltage spark will be weaker, and the fire will even be broken. As the fire is cut off from time to time, the unignited combustible mixture in the cylinder is discharged into the muffler. When it expands in the muffler, it will deflagrate when encountering the sparks in the exhaust gas, which is manifested as the muffler firing.
