By using diesel engines with high torque and instant response as offered by those with a suitable supercharging system, it proves possible to shift the average operating point close to the engine efficiency optimum. Computer analysis confirmed by chassis dynamometer tests of two car sizes equipped with Comprex charged IDI engines show a potential improvement in fuel economy of 19 - 26%. Comparison is made with a NA engine having equivalent road performance as defined by the acceleration rate.
