    摘要: An apparatus and method for utilizing any arbitrary mixture ratio of multiple fuel gases having differing combustion characteristics, such as natural gas and hydrogen gas, within an internal combustion engine. The gaseous fuel composition ratio is first sensed, such as by thermal conductivity, infrared signature, sound propagation speed, or equivalent mixture differentiation mechanisms and combinations thereof which are utilized as input(s) to a “multiple map” engine control module which modulates selected operating parameters of the engine, such as fuel injection and ignition timing, in response to the proportions of fuel gases available so that the engine operates correctly and at high efficiency irrespective of the gas mixture ratio being utilized. As a result, an engine configured according to the teachings of the present invention may be fueled from at least two different fuel sources without admixing constraints.

    摘要: The invention relates to balancing the cylinders of an internal combustion engine. The invention comprises cylinder-specific pressure sensors (1) installed in the cylinders of an internal combustion engine for measuring the cylinder pressures as well as an adjustment unit (2). The adjustment unit is arranged to determine the maximum pressure and knock value of each cylinder as well as the mean maximum pressure of the cylinders as a response to the measurements of cylinder pressures and to determine the differences between the maximum pressure of each cylinder and the mean maximum pressure. The differences are compared to a certain deviation range of the mean maximum pressure and the knock value to a certain knock limit value. The duration of the fuel injection of the cylinder is adjusted in case the difference of a single cylinder exceeds the lower limit of the deviation range and the knock value of the cylinder is less than the knock limit value or the difference of the cylinders exceeds the upper limit of the deviation range.

    摘要: A hydrogen engine 10 supplies hydrogen, oxygen, and an argon gas serving as a working to a combustion chamber 21 to combust the hydrogen. H2O in a recirculating gas discharged from the combustion chamber 21 is separated and eliminated from the gas by a condenser 66. A three-way valve 72 is switched over in such a manner that the recirculating gas flows through a product eliminating section 70 (a carbon dioxide absorbing unit 71), when the concentration of carbon dioxide in the recirculating gas is higher than a predetermined concentration, so that the carbon dioxide is separated and eliminated from the recirculating gas.

    摘要: A gaseous fuel injector 3 supplies gaseous fuel from a compressed gas cylinder 1 into a measuring portion thin tube 5 and pressure change in the tube is measured by a pressure measuring device 4 through a small hole provided in the thin tube 5. An extension thin tube 6 for removing the influence of reflected waves is provided on the downstream side of the measuring portion thin tube 5. There is provided at the downstream side end of the extension thin tube a back pressure valve 13 for uniformly increasing the pressure in the tube and for bringing the pressure close to the actual environment in the engine cylinder. Also, a tapered-shape nozzle is arranged in the measuring portion thin tube 5. Pressure measured by the pressure measuring device 4 is transduced into mass flow rate in the thin tube according to a predetermined calculation formula. Accordingly, it is possible to measure instantaneous mass flow rate of gaseous fuel injected from the gaseous fuel injector.
