PERINATAL VITAL SIGNS MONITOR

Not Available Compression ignition engines have the highest potential for efficiency, greater mass processing, and torque per cycle of all positive displacement engines, yet they are RPM limited, which severely restricts their power to weight potential. Diesel engine operation allows extreme boosting as autoignition and pressures are controlled by injection. This same injection process which allows extreme mass processing and torque, limits the allowable RPMs, and severs the diesel engine's full potential. A new cycle has now been invented which promises to allow the compression ignition positive displacement engine to reach its full potential, thus achieving extreme mass processing, with RPMs limited only by rod integrity. Pressures can now be controlled mechanically rather than by injection allowing complete injection before top dead center. This cycle known as the Separate Process Diesel Cycle promises to surpass spark ignition engines, as to power to weight, while maintaining diesel efficiencies and emissions more characteristic of spark ignition engines. Military Separate Process Diesel (SPD) designs are modeled after the two stroke spark ignition engine which offers the highest power to weight potential of all positive displacement engines. The SPD engine cycle is carried out by the separation of the compression, combustion, and expansion processes in the SPD engine. This separation of processes allows separate process optimization as is seen in the turbine engine. The inter
