PROBLEM
The existing fuel injector has a 150 degree spray pattern. During the combustion stroke (process), the current end of injection timing maps can allow the 150 degree spray pattern to temporarily impinge upon the exposed wall of the cylinder liner as the piston moves downward in the bore.
Depending on engine speed and load factors, the fuel making contact with the liner can dilute the oil film or cause excessive soot. The excessive soot can build up to form carbon deposits at the piston lands and grooves, resulting in uneven top ring and groove wear, which may cause ring breakage. This situation is aggravated by contamination within the air and lubrication systems.
