This paper reviews current differential needle valve nozzles as used in the majority of diesels and analyses their limitations. A variable area orifice nozzle is outlined that would correct the limitations of the present designs and give improved performance with lower emissions. Other engine paramenters are also investigated that would lead to improving the diesel. Two engine design concepts are proposed that could provide more that 50 miles per gallon on diesel fuel powering a 4500# car, giving adequate performance with 185 h.p..
