摘要： A fuel injection system (10) for delivering metered amounts fuel into the combustion chamber or cylinder of an engine. The fuel delivered can selectively comprise a gaseous fuel, a liquid fuel or a fuel mixture comprising the gaseous fuel and the liquid fuel. When the fuel delivered comprises a mixture of the gaseous fuel and the liquid fuel, the quantity of liquid fuel comprises a metered quantity. The quantity of gaseous fuel also comprises a metered quantity, with the metering of the gaseous fuel being regulated by prediction. The injection event involves delivering the liquid fuel and the gaseous fuel, with the metering of the gaseous fuel delivered being adjusted to allow for the quantity of liquid fuel delivered with the gaseous fuel. The injection system (10) comprises a liquid fuel circuit (11) and a gaseous fuel circuit (13), both communicating with a fuel delivery injector (15) that delivers fuel to the combustion chamber. The fuel injection system (10) further comprises an electronic control unit (ECU) for controlling operation of the fuel injection system (10). The ECU controls operation of the fuel delivery injector (15) and a fluid metering injector (31). The ECU determines the proportions of liquid fuel and gaseous fuel required to meet the fuelling demand. The ECU operates the fluid metering injector (31) to deliver the required quantity of liquid fuel into a holding chamber within the fuel delivery injector (15). The ECU also predicts the gaseous fuel flow required to deliver the necessary proportion of gaseous fuel and operates the fuel delivery injector (15) accordingly. In particular, the ECU refers to a “look-up” map or table to determine the operating parameters of the fuel delivery injector (15) to deliver the necessary quantity of gaseous fuel in conjunction with the metered quantity of liquid fuel.

摘要： If the pressure in a supply passage drops at a speed greater than a first determination speed in a state in which a first mode for supplying gas fuel to an internal combustion engine is selected, a control apparatus inhibits selection of the first mode. Then, the control apparatus switches from the first mode to a second mode, in energy other than gas fuel is used. In this state, if the pressure in the supply passage drops at a speed greater than a second determination speed, the control apparatus maintains the state in which the second mode is selected. If the pressure in the supply passage drops at a speed lower than the second determination speed, the control apparatus cancels the inhibition of selection of the first mode when it is detected that a manual on-off valve is opened.

摘要： A gas substitution ratio control system varies natural gas flow to a bi-fuel engine based on detected diesel flow to maintain a desired gas substitution ratio (GSR), without any requirement to sense engine load. In other words, GSR is controlled without monitoring engine load level. In one system, an engine is first calibrated to map actual gas and diesel flows to provide the correct GSR for all engine loads. The calibration data is then stored and diesel flow rate is monitored. The current detected diesel flow rate is used to determine the required gas flow rate for correct GSR. Gas flow to the engine is then adjusted to correspond to the required gas flow rate. Other embodiments meter gas to maintain the diesel flow rate at the same minimum level for all loads, or meter gas and diesel fuel flows to match a map of the limiting fuel energy based GSR (gas fuel energy rate/total fuel energy rate) at all loads for each engine model.

摘要： A method of controlling fuel injection in a dual fuel engine system includes determining, with a first controller, a diesel injection pulse indicative of a first amount of diesel fuel to be injected into a combustion chamber of the engine and a first timing at which the first amount of diesel fuel is to be injected. The method also includes determining, with a second controller, a combined injection pulse based on the diesel injection pulse. The method further includes injecting the second amount of diesel fuel and the third amount of natural gas into the combustion chamber in accordance with the combined injection pulse. In such a method, injection in accordance with the combined injection pulse results in a combustion event characterized by a second combustion characteristic substantially equal to a first combustion characteristic associated with the diesel injection pulse.
