-49- "INTERNAL COMBUSTION ENGINE AND OPERATING CYCLE" ABSTRACT OF THE DISCLOSURE A cylindrical rotor is mounted for rotation in a stator and the rotor includes a plurality of cylindrical bores disposed annularly around the axis thereof which are generally parallel to the stator bore. Pistons reciprocate within these bores and connecting rods or links of the pistons engage within the profile of an annular cam secured to the stator so that as the rotor rotates, the pistons reciprocate due to the cam profile. The cycle can be of a diesel type with a fuel injection or of the gasoline/air mixture type with conventional spark plugs. Of importance, is the ease with which the expansion ratio can be made greater than the compression ratio thus util- izing more of the energy normally expelled and wasted in the exhaust gases with the conventional cycles. The thermodynamic cycle in conjunction with the novel engine provides a dwell at the top or combustion stroke to provide a combustion temper- ature of not greater than 4000°C for improved engine efficiency and pollution control. Engines operating in accordance with the present thermodynamic cycle utilize the formula: Image -50- where: k is the ratio of specific heats; C is the compression ratio; 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°C to 4000°R.
