Abstract
A diesel engine ( ) has: a flow adjuster ( ) for throttling exhaust flow; an intake heater ( ) for heating intake air; a thermal medium circulator ( ) for circulating a thermal medium to warm the diesel engine ( ); a cylinder cut-off device ( ) for conducting cylinder cut-off; and a fuel injection timing advancing device ( ) for advancing timing for supplying fuel to a cylinder, the respective devices being actuated at least from pre-high-idle step to a neighborhood of high-idle condition, so that fuel combustion stabilization of the diesel engine ( ) can be rapidly enhanced during a period where less fuel is supplied into the cylinder and fuel combustion time is short, thus greatly reducing discharge of white smoke and possibility of engine bunching.
