Abstract
An internal combustion engine of the four cycle reciprocating piston type wherein intake and exhaust of working fluid and combustible fuel into the engine cylinder is controlled by poppet valve means, while induction air is diverted by rotary valve means between intake and exhaust, said valve means being operated in timed relation with respect to each other at half crank shaft speed of rotation, utilizing blower induction of air as the working fluid which is diverted between intake and exhaust, and advantageously employing fuel injection through a valve plenum that is ported and through which the working fluid is controlled by the cooperatively timed rotary and poppet valve means.
Claims17
A four stroke internal combustion reciprocating piston and cylinder engine including;
- induction and exhaust stacks, blower means supplying air to said induction stack, a first valve means opening into the cylinder and controlling intake, compression, power and exhaust strokes thereof, and a second valve means opening sequentially (1) to divert induction air into the cylinder through said first valve means during the intake stroke, (2) to divert induction air into the exhaust stack during the compression and power strokes, and (3) to divert exhaust gases from cylinder and through said first valve means into the exhaust stack during the exhaust stroke, there being means for timing the said first and second valve means and for timed induction of fuel during the power stroke.
A four stroke internal combustion engine of the reciprocating piston and cylinder type, and including;
- a head having a valve plenum with adjacent induction and exhaust stacks at one side thereof, blower means supplying air to said induction stack, a first valve means opening from the other side of the plenum and into the cylinder, and a second valve means operating within a port defined by the plenum to extend between said induction and exhaust stacks and controlling said plenum stacks to divert working fluid sequentially (1) from the induction stack and through said first valve means and into the said cylinder during the intake stroke, (2) from the induction stack to the exhaust stack during the compression and power strokes, and (3) from the said cylinder and through said first valve means to the exhaust stack during the exhaust stroke, there being means for timing the said first and second valve means and for timed induction of fuel for the power stroke.
