Why Direct Injection Engines Suffer From Carbon Buildup
What Causes Carbon Buildup on Intake Valves Quick Summary The problem of carbon buildup on the intake valves of a direct injection engine is real. It’s caused by multiple factors, including: • The elimination of the fuel wash that was common in port-injected engines. • More soot generation during cold start operation • Different piston ring and cylinder wall finishes that reduce friction — • Leaner air-fuel mixtures • Longer oil change intervals • Engine designs that change airflow under differing engine conditions. Short trips, extended oil-change intervals, and worn … Read More
