摘要:
A gas powered internal combustion engine in which the gas is provided from the gas phase of a pressurized liquid gas in an liquified petroleum gas container and in which the liquified petroleum gas container is rigidly mounted adjacent to the internal combustion engine at a preselected angle to be in conductive heat transfer relationship to the internal combustion engine and in vibration receiving relationship to the internal combustion engine whereby the liquified gas in the liquified petroleum gas container is heated and vibrated and the effective surface area thereof is thereby increased. A pressure regulator is provided for receiving the gas from the liquified petroleum gas bottle regulating the pressure of the gas transmitted to the internal combustion engine and at least one flexible hose is connected to the pressure regulator for transmitting the gas therethrough. A vibration and/or heat limiting member may be incorporated to reduce the frequence and amplitude of the vibration and limit the amount of heat transferred to the liquified petroleum gas.
摘要:
A heated fuel filter assembly (5), particularly for use with engines operating using plant oil as a fuel. A filter housing (42) is connected to a filter head (39). A cylindrical filter screen (43) within the housing, separates the interior of the housing into internal (44) and external (45) portions. An inlet fuel conduit (40) communicates with the internal portion, and an outlet fuel conduit communicates with the external portion. An elongate heating member (46) projects axially into the internal portion so as to heat fuel within the filter assembly. The heating member may be a hollow member through which engine coolant circulates.

摘要:
The present disclosure refers to a device and method for operating an internal combustion engine. The internal combustion engine may be configured to be operated in an operation mode in which fuel of a specific type injected into at least one combustion chamber, and in a standby mode in which no fuel is burned in the at least one combustion chamber. The method may comprise the steps of circulating heated fuel during the standby mode of the internal combustion engine and circulating lube oil (35,40,50,60,70) during the standby mode of the internal combustion engine. Thermal energy may be transferred in a heat exchanger (25) from said circulating heated fuel (20,30) to said circulating lube oil (35,40,50,60,70), such that said lube oil is heated thereby during the standby mode of the internal combustion engine. Said circulating heated lube oil may be supplied to the at least one injector (15) for heating purposes during the standby mode of the internal combustion engine.
摘要:
The present invention provides a heated catalyzed fuel injector that dispenses fuel substantially exclusively during the power stroke of an internal combustion engine, wherein ignition occurs in a fast burn zone at high fuel density such that a leading surface of the fuel is completely burned within several microseconds. In operation, the fuel injector precisely meters instantly igniting fuel at a predetermined crank angle for optimal power stroke production. Specifically, the fuel is metered into the fuel injector, such that the fuel injector heats, vaporizes, compresses and mildly oxidizes the fuel, and then dispenses the fuel as a relatively low pressure gas column into a combustion chamber of the engine.
