Abstract
THE NEW DIRECT-INJECTION diesel engines — the naturally aspirated 16000 and the turbocharged 21000 — were developed to power specific crawler and wheel vehicles built by Allis-Chalmers. Thus the original design and performance specifications were defined by the space available in these machines, and by the power and torque characteristics required by them. Also, the engines had to be suitable not only for commercial applications such as generator sets, shovels, and compressors, but also for oil field and marine service.
Torque and speed requirements indicated that a 5¼-in. bore and 6½-in. stroke would give the desired performance. To meet the low heat rejection and good starting requirements, an open-chamber combustion system had to be used. The three-valve arrangement — two intake and one exhaust — was chosen because it offered low pumping losses and reasonable cost.
This paper describes the design considerations and development work which produced the new diesel engines.*
