ABSTRACT:
A fuel injected heat engine of the reciprocating type wherein a piston moves reciprocally within a cylinder to compress gases for the support of combustion and to be moved by burning gases to turn a crank with torque, there being a low compression storage chamber of substantial volume normally open into the cylinder and closed by upward movement of the piston to withhold gases at combustion supporting temperature, there being a high compression auto ignition chamber of limited volume comprising the upper portion of the cylinder and isolated from said low compression chamber by said piston closure thereof for continued compression of combustion supporting gases by said piston movement to auto ignition temperature, and there being constant volume fuel injection means for injecting fuel at high pressure into the auto ignition chamber and at a progressively diminishing rate as the first mentioned storage chamber is re-opened and as the cylinder pressure decreases during the effective power stroke.
