    摘要： An internally cooled internal combustion piston engine and method of operating a piston engine is provided, with the combination of liquid water injection, higher compression ratios than conventional engines, and leaner air fuel mixtures than conventional engines. The effective compression ratio of the engines herein is greater than 13:1. The engines may employ gasoline or natural gas and use spark ignition, or the engines may employ a diesel-type fuel and use compression ignition. The liquid water injection provides internal cooling, reducing or eliminating the heat rejection to the radiator, reduces engine knock, and reduces NOx emissions. The method of engine operation using internal cooling with liquid water injection, high compression ratio and lean air fuel mixture allow for more complete and efficient combustion and therefore better thermal efficiency as compared to conventional engines.

    摘要： An injector nozzle used with an internal combustion engine for shaping a fluid flow is provided. The nozzle has a body and an orifice plate provided at an outlet of the body. The body and the plate extend symmetrically with respect to a central axis. The plate has an interior surface and an opposite exterior surface, which are substantially parallel to each other to define a thickness of the plate. The plate has fluid passageways each having an orifice on the exterior surface. The fluid flow diverges through the fluid passageways to create stream jets. The imaginary extensions the passageways converge to create a focal point and an included angle associated with the focal point.

    摘要： An internal combustion engine is provided equipped with an exhaust gas recirculating (EGR) system and means for internally cooling the exhaust gases by a spray of atomized water into the recirculated exhaust gases prior to ignition. The atomized water spray may be in the intake manifold or directly in the cylinder. The engine may employ spark or compression ignition. The internal combustion engine operates with compression ratios greater than 12:1 and lean air:fuel ratios. Also provided is a method for controlling the amount of exhaust gas recirculated in the engine, and for controlling the amount of water added. The inventive engines have elevated thermodynamic efficiencies and favorable NOx emissions.
