Carbon Cleaning
Carbon buildup on engines equipped with direct injection (DI) is a well-known issue, particularly in modern gasoline engines. It's a problem that can affect engine performance, fuel efficiency, and emissions, and is especially prevalent in many vehicles with turbocharged engines or those that rely heavily on direct injection technology, such as certain Audi, Volkswagen, BMW, and other European models.
Walnut blasting is one of the most effective methods for cleaning carbon buildup on the intake valves of engines equipped with direct injection (DI). The process involves using finely ground walnut shells to gently scrub and remove carbon deposits that accumulate on the intake valves over time. This method is particularly necessary because, unlike in traditional port fuel injection (PFI) systems, direct injection engines don’t have fuel flowing over the intake valves to clean them. Over time, carbon buildup can obstruct airflow and reduce engine performance. Walnut blasting helps restore proper airflow and maintain engine efficiency.
