Abstract
A control apparatus is configured to enhance turbulence in the cylinder produced by the fuel spray, and to improve combustion stability (promote flame propagation) in an ATDC designed to reduce HC and/or achieve early activation of the catalyst. Ignition timing is set to compression top dead center (TDC) or later when needed such as when the catalyst requires warming. In one fuel injection timing, the fuel is injected in two fuel injections with a first fuel injection occurring during the compression stroke, and the second fuel injection being carried out at 45° BTDC or later.
