What are the common issues with the Changan 1.6 direct injection engine?

[Roman]

Common issues with the Changan 1.6 direct injection engine may include the following: Oil dilution: This is usually a defect left during engine production by the manufacturer. Since the Changan 1.6 direct injection engine uses a direct injection method, it is difficult to avoid the issue of oil dilution. Prone to carbon buildup: Frequent ignition can lead to carbon buildup, as each cylinder of the Changan 1.6T direct injection engine ignites approximately 50 times per second. Short lifespan of spark plugs: Due to the high ignition frequency of the direct injection engine, reaching around 3000 times per minute, spark plugs are prone to carbon buildup. Excessive carbon buildup necessitates replacement. High fuel requirements: Maintenance costs are expensive. If the fuel quality is poor, the vehicle may emit black smoke while driving. Loud engine noise: The Changan 1.6 direct injection engine produces significant noise during operation. This is because its fuel injection pressure is over ten times higher than that of a conventional engine, and high-pressure injection causes nozzle vibration, resulting in loud noise.
