While gasoline direct injection technology is one of the fastest growing engine markets, there are several consequences associated with this new type of engine. As it ages, there are a number of potential issues that direct injection technology can cause from a maintenance standpoint. The greatest of which is that with this new direct injection tech can cause severe deposits to form within your engine. These deposits are a result of gasoline being sprayed directly into the combustion chamber without intake valve washing taking place. Port fuel injection systems, on the other hand, helps to wash intake inlets by virtue of their design. Without this washing of the intake valves, deposits occur at higher rates in the direct injection engines. Additionally, direct injection technology engines spray gasoline directly into the combustion chamber under much higher pressure than in a port fuel injection system. This causes the contaminants to blow past the piston rings and into the oil sump. A ... read more
