デイーゼルエンジン。 A combustion chamber is defined between a cavity that opens at the top of the piston and a cylinder head, a fuel injection nozzle is installed facing the center of the combustion chamber, and two intake ports are opened in the cylinder head in parallel around the injection nozzle. Each intake port has a different inclination angle and flow path shape with respect to the combustion chamber wall of the cylinder head, and an intake valve is installed to open and close each intake port in synchronization with engine rotation. A direct injection diesel engine characterized by having a configuration in which a throttle valve is installed to control the intake air flow ratio introduced from each intake port according to engine operating conditions.
