Abstract

In a four-stroke cycle, the expansion ratio is greater than the compression ratio thus utilizing more of the energy normally wasted. A cylindrical rotor 15 is mounted for rotation in a stator 10 and includes a plurality of cylindrical bores 18 disposed annularly around the axis thereof generally parallel to the stator bore. Pistons 19 reciprocate within the bores 18 and connecting rods or links of the pistons engage within the profile of an annular cam 24 to turn the rotor. A dwell may be provided at the top of the combustion stroke to provide a combustion temperature of not greater than 4000 DEG C for improved pollution control. The air standard thermal efficiency is given by <IMAGE> where: J is the mechanical equivalent of heat; k is the ratio of specific heats; R is the gas constant; C is the compression ratio, Cv is the specific heat at constant volume; E is the expansion ratio; Tb is the temperature at the end of compression; and Tc is the temperature at the end of combustion and is from about 3000 DEG C to 4000 DEG R. <IMAGE>
