An analysis of a highly compounded two-stroke-cycle compression-ignition engine

Presents an analysis of a compound engine operating with manifold pressures ranging from 60 to 110 lb/sq in. absolute. The effects of engine limits (peak cylinder pressure and turbine-inlet temperature) and component efficiency are discussed. A range analysis is used to evaluate the merit of the engine. The analysis indicates that specific-fuel-consumption values of 0.32 lb/bhp-hr and specific weights of 0.8 lb/bhp are obtainable at high manifold pressures.

Experiments on self-ignition of liquid fuels

This report examines the cause and effect of the energy conversion in airless-injection engines. In order to obtain a criterion for the chosen working method, it takes into consideration the time relations between the individual processes. Observations of the engine alone do not suffice to obtain the necessary basis for a critical analysis of the processes.
