Abstract
An induction valve of a direct fuel injection diesel engine has helical flow director flanges formed on the upstream side for directing the inducted air into a vortical flow within the combustion chamber. The flow directing flanges are formed on the valve and the induction port with which the valve is associated has an extremely simple configuration. An induction passage liner is simply configured to reduce the resistance to air flow.
