Is Carbon Buildup Severe in Skyactiv Engines?

[StLaura]

Skyactiv engines can experience severe carbon buildup, which leads to the following consequences: 1. Reduced engine power, resulting in uneven and gradually diminishing power output, as well as increased fuel consumption and higher economic burden; 2. Difficulty in cold starts, making the engine harder to ignite; 3. Severe carbon buildup in the combustion chamber can also cause cylinder knocking, noise during low-speed acceleration, and damage to pistons and crankshafts, significantly compromising vehicle safety. The solution for carbon buildup in Skyactiv engines is to spray atomized gasoline onto the intake valves, which helps dissolve and clean the carbon deposits. The Skyactiv engine was introduced by Mazda Motor Corporation of Japan in October 2010, with a compression ratio reaching 14.0:1 for the first time. The high-compression combustion significantly improves engine efficiency, reducing fuel consumption and increasing torque by over 15%.
