How to Check for Engine Misfire?

[MacMadeline]

Engine misfire can be checked by observing whether the engine operates abnormally or lacks power, whether the engine runs unevenly and vibrates rhythmically at high, medium, and low speeds, and whether the muffler emits black smoke and backfires. The hazards of engine misfire include: 1. Decreased engine speed and power; 2. Increased fuel consumption and emission pollution; 3. Accelerated wear of moving parts, shortening the service life of lubricating oil. Engine misfire refers to engine failure resulting in insufficient power, leading to loss of power, fewer cylinders operating, or some cylinders not working. Engine misfire can shorten the service life of lubricating oil and may cause sudden stalling, excessive fuel consumption, black smoke emission, and lack of power.
