Abstract
A 2-cycle engineis provided with an ignition device; an exhaust control valve; and a controllerfor controlling the ignition deviceand the exhaust control valve. The controllercontrols spark ignition combustion by activating the ignition devicein a high load range, and controls self-ignition combustion of a mixture in the combustion chamberby adjusting pressure in a cylinder chamberwith adjustment of the opening of the exhaust portin a low load range. In a low load and low rotational speed range, moreover, there is formed a stratified mixture field, in which the air and the fuel are much distributed in the central portionof the combustion chamberand in which burned gas remaining in the combustion chamberis much distributed in the outer sideof the central portion of the combustion chamber, so that the self-ignition combustion of the mixture may be performed by forming the stratified mixture field in the low load and low rotational speed range.
