Fuel mixture system and assembly

摘要

A system and attendant structural assembly operative to establish a coordinated mixture of gaseous and distillate fuels for an engine including an electronic control unit (ECU) operative to monitor predetermined engine data determinative of engine fuel requirements and structured to regulate ratios of the gaseous and distillate fuel of an operative fuel mixture for the engine. The system and assembly includes at least one mixing assembly comprising an integrated throttle body and air gas mixer directly connected to one another, wherein the throttle body is disposed in fluid communication with a pressurized gaseous fuel supply and the air gas mixer is disposed in fluid communication with a flow of intake air to a combustion section of the engine. In use, the throttle body is structured to direct a variable gaseous fuel flow directly to the air gas mixer for dispensing into the intake air flow to the combustion section.

主权项

1. A control system for establishing gaseous fuel input for an engine operative on a variable mixture of gaseous and distillate fuels, said control system comprising:
a monitoring assembly comprising a plurality of sensors disposed and structured to monitor a plurality of operating parameters over a plurality of variable load conditions of the engine, said plurality of sensors further comprising a plurality of mass airflow (MAF) sensors, a plurality of temperature sensors, and a plurality of knock sensors, an electronic control unit (ECU) configured to interpretively process data from said monitoring assembly associated with said plurality of operating parameters, and said ECU operative to establish a concentration of the gaseous fuel in the variable fuel mixture to comply with any of said plurality of operating parameters being monitored.
