Filed: 2002-11-26
Abstract: <P>PROBLEM TO BE SOLVED: To effectively inhibit generation of black smoke in a fuel injection type internal combustion engine when injection timing is moved from a compression stroke to an intake stroke.  <P>SOLUTION: Immediately after the injection timing is moved from the compression stroke to the intake stroke, a retard amount for countermeasures against black smoke dinj is set (S120) and the fuel injection timing is temporarily retard (NO in S118, S120). Thanks to this, in the intake stroke, fuel injection is implemented with a piston sufficiently separated from a fuel injection valve. At the start of injection in the intake stroke, therefore, adding a large amount of fuel to adhering fuel accumulated on the piston top face at the time of injection in the compression stroke is prevented. As a result, the amount of fuel burning in an after-burning state can be reduced and the generation of the black smoke can be effectively inhibited.  <P>COPYRIGHT: (C)2004,JPO
