Abstract
A two-cycle engine that includes a high pressure fuel pump that pressurizes fuel to produce pressurized fuel and pumps the pressurized fuel from a fuel controller to a fuel injector. The fuel injector injects the pressurized fuel into a cylinder. A high pressure air pump pressurizes air to produce pressurized air and pumps the pressurized air from an air controller to an air injector. The air injector injects the pressurized air into the cylinder.
Claims8
A two-cycle engine, comprising:
- a cylinder;
- a fuel controller that receives fuel from a fuel reservoir;
- a fuel injector;
- a high pressure fuel pump that pressurizes fuel to produce pressurized fuel and pumps the pressurized fuel from the fuel controller to the fuel injector, the fuel injector injecting the pressurized fuel into the cylinder;
- an air controller that receives air;
- an air injector;
- a high pressure air pump that pressurizes air to produce pressurized air and pumps the pressurized air from the air controller to the air injector, the air injector injecting the pressurized air into the cylinder;
- and,
- a piston assembly within the cylinder, the piston assembly including a piston and a sealing mechanism;
- wherein the piston assembly comprises:
- piston slide valves,
- piston slide valves frames connected to the piston side valves,
- piston slide valve return springs on the piston slide valves frames,
- a piston valve action pusher,
- piston valve push return springs connected to the piston valve action pusher, and
- a supplemental piston ring.
