Endoreversible Joule-Brayton cogeneration cycle has been optimized based on a new criterion, total useful energy-rate (including power output and useful heat output), and the efficiency at maximum total useful energy rate has also been determined. The effects of various cycle parameters on the...

Previously, the authors have designed and implemented an active motion control “virtual crankshaft” for a free piston engine, which enables precise piston tracking of desired trajectories. With this mechanism, the volume of the combustion chamber can be regulated, and therefore the pressure,...

The study approach of this paper is to combine experiment and simulation on using butanol as fuel in gasoline engine. First, experiments were performed under full load on a single cylinder spark ignition engine fueled with 35%vol butanol–gasoline blend and the pure gasoline, respectively. The...
