Development of a Turbocharged Two-Cycle Air Cooled Diesel Engine

This paper describes the development of the turbocharged 2-cycle air-cooled diesel engine with 4-,6- and 10-cyl engine series featuring unique designs in their respective component parts. Development was initially begun on a single-cylinder engine, on which tests were carried out. Following that, full-scale engine experimentation was carried out using a 4-cyl prototype engine, after which successive tests were made on each cylinder series. The turbocharged 2-cycle air-cooled diesel engine is especially noteworthy for such features of its construction as its mechanically driven exhaust turbocharger, cooling methods for cylinder, cylinder head, and piston.
