The Adiabatic Engine for Advanced Automotive Applications
The high temperature adiabatic diesel emerges as a possible contender for future automotive powerplants. The powerplant under consideration is the insulated diesel type engine without a cooling system. A waste heat recovery system is considered for further improvement. Considerable progress has been made in this technology by many organizations. Currently the thermodynamics, high temperature tribology, materials, design emissions and performance aspects of the adiabatic engine are being investigated worldwide. The possible role of the adiabatic engine in future automotive type engines, and the rotary Wankel type engine are also presented. Its potential performance improvement is discussed. The advantages of the adiabatic engine concept for multi-fuel capability in direct-fired coal combustion and other degraded fuels are covered. Finally, the technical problem areas holding back its commercialization are presented.
