INCREASED DIESEL ENGINE EFFICIENCY BY USING NITROUS OXIDE AS A FUEL ADDITIVE

摘要

A diesel engine fuel delivery system is equipped for addition of N2O to the fuel supply of a diesel engine. Fuel from a tank passes through an outlet tube to a low pressure pump which delivers it through a fuel filter. Simultaneously liquid N2O from a pressurized tank passes through a metering valve where it merges with the fuel before passing through a high, constant pressure, on-demand pump. The N2O-loaded fuel then enters a high pressure manifold, called a common rail, where its pressure is monitored by a sensor before it enters individual injectors which spray it, with proper timing into the combustion zone of each cylinder. The desired fuel injection timing can be adjusted and controlled by an electronic engine control unit similar to those commonly installed on modern vehicular diesel engines.
