ABSTRACT:
An improved internal combustion engine is disclosed having no rotating crank shaft. Each piston rod of the engine is connected to a hydraulic piston and cylinder the output of which drives the rotating output shaft of a hydraulic motor. A take off from the shaft of the hydraulic motor drives an air compressor which feeds compressed air to the combustion chamber through the latter's intake valve. Fuel is mixed with the compressed air before entering the combustion chamber and a conventional spark plug and coil is employed to ignite the fuel/compressed air mixture. The compressed air also is used to actuate the intake and exhaust valves of each cylinder through a solenoid controller. A computer is adapted to send signals to each valve solenoid to control its movement and to each spark plug coil in response to a throttle input and a piston displacement input applied to the computer. The input signal sensing piston displacement in each cylinder is derived from a linear potentiometer coupled between the piston rod and the hydraulic cylinder. The computer also operates a master hydraulic valve between the hydraulic cylinders and the hydraulic motor to control the direction of rotation of the hydraulic motor output shaft. Water injection means are provided for cooling each combustion chamber thereby dispensing with a conventional radiator cooling system.
