parallel to the cylinder bore therefore the injector targeting detailed in table 1 taken with a 27 5 u00b0 injector installation angle indicates the actual in cylinder spray targeting this installation angle of the injector is provided as an example but identical in cylinder jet targeting can be obtained for other installation angles by adjusting the location of the jets on the injector the jet angles in table 1 should be considered as a range centered about the value in the table plus or minus 5 u00b0 the x y and z coordinates change accordingly from the specifications in table 1 for individual spray jets within the specified range the spray jets were designed to avoid valve wetting and to minimize liner and piston wetting in addition the jets were designed to interact with a shallow bowl piston design to produce a stable stratified mixture around the spark plug for cold start stability and emissions reduction jets 1 4 are provided for good mixing in homogeneous charge operation jets 1 and 3 spray are targeted between the intake valves and reach as far as possible on the exhaust side with minimal bore liner wetting jets 2 and 4 are oriented to minimize valve wetting as valve wetting is a major source of soot jets 3 5 and 6 provide good combustion stability for light stratified charge at cold start operation by ensuring that the jets are substantially contained in the shallow piston bowl it has been found that more jets targeting the piston bowl aid in producing a stable and rich mixture around the spark plug that improves.
