ABSTRACT:
Disclosed is an engine for an automotive vehicle designed such that a mixed gas supplied to the combustion is burned first in the periphery of the combustion chamber and then over the entire length in the peripheral direction of a cylinder, followed by burning the mixed gas in the center of the cylinder. Plural sources of ignition, i.e. ignition gaps of spark plugs, are so disposed at a peripheral end portion of the combustion chambers in spaced relationship with each other in a cylindrically peripheral direction as to allow the flame ignited by each of the spark plugs to coincide or collide with each other in the cylindrically peripheral direction and thereafter in the center of the cylinder. This arrangement can eliminate NOx and HC and perform dilute combustion, thereby improving fuel economy.
