The methods include a synchronization method where an alternative fuel injector control signal is synchronized among two or more alternative fuel injectors throughout the engine's energy demand range; a method for transforming non-sequential conventional fuel injector control signals to individual cylinder timed alternative fuel injector control signals; a method for transforming sequential multi-port conventional fuel injector control signals to throttle body alternative fuel injector control signals; and a method which includes adjusting the timing of the start of the injection relative to the valve opening event as a function of fuel flow.Field of SearchFuels, lubricants and additivesActuator circuit (e.g., engine condition responsive electronic circuit actuates injector valve) Having microprocessor Having specific transducer Fuel viscosity sensor (e.g., temperature sensing) Combined liquid and gaseous fuel Gaseous fuel and air mixer Diverse fuel supply Electrically actuated injector | |
