Abstract
Comprehensive experimental results obtained with a 4-stroke diesel engine are presented. Development of the differential compound engine in its present form, with flexible, multivariable operating controls, is given in detail.
Output shaft torque and power envelopes demonstrate both constant power and implied high torque backup. The possibility of stepless transmissions or, at most, a 2-forward/reverse ratio gearbox, makes the unit particularly attractive for a wide range of transport applications.
