The purpose of the Wicks Combined Cycle Engine (WCCE) is to provide a very substantial fuel efficiency improvement relative to the liquid cooled, internal combustion, piston engines that are now utilized by virtually all automobiles, trucks, and buses, and most trains and ships. The method is to recover virtually all of the internal combustion engine heat that is normally rejected through the engine coolant radiator and through the engine exhaust, by a Rankine Cycle that is comprised of a feed pump, feed heater, boiler, superheater, turbine or other type of mechanical power producing expander and air cooled condenser. The reference analysis shows a potential efficiency increase from 25% for existing practice engines to 41.8% for the WCCE.

In combination, an internal combustion engine including an exhaust gas flow conduit and a circulating coolant flow loop, a Rankine cycle engine including in flow series an expander, a condenser, a feed pump, and a steam generator, said steam generator receiving the waste heat from the exhaust conduit and the coolant loop, the improvement comprising: said steam generator consisting of three sections, passing the working fluid of the Rankine cycle engine serially through each of the sections, passing the exhaust flow through each of the sections in counter-current flow with the working fluid flow, whereby the working fluid is preheated in the first section, vaporized in a second section, and superheated in a third section, passing the coolant flow through the second section such that the fluid is vaporized as a result of thermal heat exchange with both the exhaust and coolant flows.
