摘要： A secondary fuel injection system determines (precisely) a maximum amount of secondary fuel that can be injected into a cylinder during a cycle based upon the rotational speed (RPM) of the engine. A primary fuel injection pulse width of the prior cycle and is used to determine how much heat energy was requested by an engine control module based upon the duration of the injection pulse. Secondary fuel is injected into the intake port of the cylinder after the exhaust valve closes in an amount that is calculated based upon the maximum that can be injected during the allowed calculated time of crankshaft rotation and the amount of heat energy requested in the prior cycle and to include the amount of primary fuel that is then injected into the cylinder is being reduced based upon the amount of heat energy provided by the secondary fuel that was previously injected.

摘要： The invention presents a method of converting a diesel fueled engine to a blended-fuel engine capable of operating on blended gaseous fuel and diesel fuel, where the diesel fueled engine has a plurality of cylinders, a plurality of diesel fuel injectors for injecting diesel fuel into the cylinders, and an Engine Control Unit (ECU) for controlling at least the operation of the diesel injectors by sending diesel fuel injector control signals to the diesel fuel injectors.
