Abstract
A piston engine includes a nozzle-diffuser providing air-fuel to the crankcase. The nozzle-diffuser has input and output ends, and a throat between the input and output end having a cross sectional area that is smaller than the cross sectional areas of the input or output ends, and in which the interior surfaces of the intake port are tapered. The nozzle-diffuser may be housed in the crankshaft, and it alters the speed, pressure and temperature of the air fuel charge. Improvement of fuel air mixing to a more homogeneous charge and delivery rate of result in increased power, improved fuel economy and reduced exhaust gas emissions by the engine.
