Abstract
A dual intake valve type internal combustion engine comprises a main intake valve and an auxiliary intake valve. The main intake valve is so constructed that the combustible gas mixture introduced into the combustion chamber therethrough is caused to generate a swirl motion. A variable valve lift type of auxiliary intake valve is constructed, and the valve lift of the auxiliary intake valve is varied in accordance with the changes in the engine operating conditions.
