MOMENTUM DRIVEN FUEL INJECTION OF STEAM AND FUEL VAPOR FOR COMPRESSION IGNITION ENGINES

The present invention directly affects two primary limitations of diesel fuel: poor vaporization and ease of auto-ignition. Superheated fuel is injected within a cone of steam. As a result, fuel is fully vaporized and steam controls ignition by momentarily isolating fuel from air. In order to achieve high vapor velocities, the present invention uses momentum of circulating fuel and water to propel them through the injector. Momentum is preserved by transfer valves that transfer moving liquids between through paths and injection paths. Momentum is further preserved by an injector design that minimizes turbulence that would absorb energy and reduce injected velocity. The fuel and water may be superheated before injection to convert to steam and vapor upon the release of pressure when injected into the combustion chamber. The injector may also be used to achieve high injection velocity for liquid fuel injection without heating. 1.

Engine provided with cda apparatus and water pump and control method for the same

The present invention relates to an engine provided with a CDA apparatus and a water pump and a control method thereof. The control method comprises: a step in which a plurality of sensors detect vehicle driving information and outputs a signal corresponding thereto; a step in which a controller determines whether a current vehicle driving state corresponds to a CDA driving area on the basis of the output vehicle driving information; a step in which the controller operates a CDA apparatus of a partial cylinder when the current driving state corresponds to the CDA driving area; a step in which the controller determines whether a knocking occurrence ignition timing (DBL; Detonation Border Line) of a cylinder with a CDA apparatus which is not operated precedes minimum spark advance for best torque (MBT); and a step in which the controller operates a water injection nozzle to inject a currently operated cylinder when the knocking occurrence ignition timing (DBL) precedes the minimum spark advance for best torque (MBT).
