A small and compact, three cylinder, turbocharged DI diesel engine with displacement of 1.08 liter (360 cc/cyl.), has been constructed, and the feasibility of achieving high thermal efficiency together with high power and low noise has been studied. The engine was designed to match the small engine compartment arising from the vehicle design concept of having the same interior space as a Compact Car with a Mini-compact Car size of 1750 lbs inertia weight class. A remarkable engine performance, that is the minimum specific fuel consumption of 208 g/kwh (153 g/psh) and the power of 41 kw (56 PS) at 4800 rpm were obtained, which resulted from combustion system optimization as well as a rigid but lightweight and low friction design. The noise was as low as an ordinary IDI diesel engine. The combined fuel economy based on the '75 FTP reached 90 mpg on a vehicle in the 1750 lbs inertia weight class, with the above research engine.
