Özet

Performance examinations of a dual-Diesel cycle engine in point of engine performance characteristics such as exergy efficiency, power and power density have been conducted. The effect of design parameters of the engine cycle such as intake temperature, intake pressure, piston friction coefficient, average piston velocity, engine revolution, stroke length, residual gas fraction, engine pressure ratio, engine temperature ratio, compression ratio, ratio of bore diameter to stroke length, and equivalence ratio, on the performance characteristics are evaluated by considering variable specific heats and irreversibilities resulting from exhaust output, heat transfer, incomplete combustion and friction. The results can provide substantial information researchers who study on dual-Diesel cycle engine design and manufacture.
