Patent ID: 6889636

Claim:
A two cycle engine comprising: (a) a valve housing having a reversibly displaceable valve member displaceable in a substantially vertical direction, said valve member having a valve head and a valve stem, said valve member being displaceable between an open position and a closed position; (b) a cylinder housing being substantially vertically aligned and secured to said valve housing, said cylinder housing having an upper section and a lower section forming a combustion chamber containing a reversibly displaceable piston member, said cylinder housing upper section having (1) at least two air intake ports, (2) a fuel injection port, and (3) means for igniting a fuel and air mixture, said cylinder housing lower section having an exhaust port for egress of exhaust gases; (c) a crank housing coupled to said cylinder housing lower section for containing a crank member coupled to said piston member; (d) an air intake plenum located within said valve housing and surrounding said valve stem, said air intake plenum in fluid communication with said intake ports; and, (e) valve control means for initiating displacement of said valve member when said valve member is in a substantially open position and terminating displacement of said valve member when said valve member is in a substantially closed position, said valve control means including: (i) a solenoid having a solenoid actuating rod extending through a wall of said valve housing; and (ii) valve trigger means located internal said valve housing, for intercepting said valve member when said valve member is in said substantially open and closed positions, said valve trigger means being pivotally coupled to said valve housing wall and coupled to said solenoid actuating rod.
