DIRECT INJECTION = Carbon around Intake Valves

7 Janvier 2016

The new generation direct injection engines used injectors located directly inside the cylinders, and not on the outside and above the intake valves. Thus, only the air and gases passing throu gh the intake valves in a direct injection engine, and therefore, no injection of gas under pressure repetitive do help clean intake valves.

n an older engine which uses the conventional injection, that is to say, in the intake duct, the injectors are located above the intake valves. When they spray the fuel in the cylinder, fuel "cleanse" the top of the intake valves in passing.

En route to the cylinders, oil and gases vapors cross the intake valves, called the oil vapor deposition, and they can leave deposits in the form of sludge. Over time, the accumulation of grease can cause a lot of trouble. The effects may be worse on turbo engines with direct injection, generating more heat and pressure responsible for the oil vapor deposition.

To remedy this problem TITAN created two complete cleaning fuel system kits.
