Fuel mixture system and assembly
First Claim
1. A control system for establishing gaseous fuel input for a compression ignition engine operative on a variable mixture of gaseous and distillate fuels, said control system comprising:
- a monitoring assembly operatively disposed and structured to determine a plurality of three predetermined operating parameters of the engine, independent of load conditions of the engine;
said three predetermined operating parameters comprise mass flow rate of intake air to the combustion section of the engine;
temperature of exhaust gas from the combustion section and an occurrence of engine knock in the combustion section;
said monitoring assembly comprising at least one of mass airflow (MAF) sensor structured to monitor the mass flow rate of air and disposed in monitoring relation to the intake air flow to a combustion section of the engine;
at least one temperature sensor structured to monitor the temperature of the exhaust gas and disposed and structured to determine temperature of exhaust gases from the combustion section of the engine and at least one knock sensor operatively disposed relative to the combustion section and structured to determine an occurrence of engine knock;
an electronic control unit (ECU) connected to said monitoring assembly and configured to interpretively process data from said monitoring assembly, associated with at least two of said plurality of three operating parameters, andsaid ECU operative to establish a concentration of gaseous fuel in the variable fuel mixture sufficient to comply with monitored ones of said three predetermined operating parameters.

Abstract
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.
