The paper describes an analytical and hardware design study aimed at evolving a low heat loss version of a current turbocharged production diesel engine, the Ford Dover engine.
The analytical approach was done using the Ford engine simulation program and aimed to establish whether reduction in heat loss would be advantageous for this particular engine. Various levels of insulation were assumed on the piston crown, the cylinder head and the cylinder liner, and the effect on power output and fuel economy was assessed. It was found that reduced heat loss could be implemented without any major design changes and would result in benefits in both power output and fuel economy. New pistons and alterations to the combustion space were then evolved and specified in detail to bring about the desired reduction in heat loss. Thermal analysis of these designs using finite element and other approaches confirmed their suitability.
The paper describes the approach, the various stages in the development of the designs, their assessment, and the predicted performance of the proposed low heat loss Dover engine.
