ABSTRACT:
Improved engine performance and reduced temperatures of combustion and engine components giving lower NO exhaust emission results when a turbocharged Roots blown two-cycle diesel engine is provided with a flow restricting aftercooler between the positive displacement Roots blower and the engine cylinders. A preferred arrangement for a V-type engine mounts the after cooler in the engine cylinder block within the air box space between the cylinders and beneath the cylinder block-mounted Roots blower for a compact arrangement with simple connections to the engine coolant jacket and minimum changes to engine airflow. High velocity airflow in the cooler and scrubbing of the cooled air box lower wall provide good cooling efficiency as well as avoiding plugging of cooler air passages with carbon and other airborne particles.
