ECV 5 Air-Fuel Ratio Control Gas Valve

The ECV 5 is a complete Emissions Control System for Gas Engines. The ECV 5 can be configured for controlling either Rich Burn or Lean Burn Gaseous Fueled engines (fuel can be either Natural Gas or other Alternative fuels). The system consists primarily of the variable pressure control valve which accepts an input from either a narrow band or a wide band Oxygen sensor located in the exhaust of the engine. The ECV 5 valve will vary the fuel pressure based on an O2 setpoint compared to the actual O2 reading from the oxygen sensor. This closed loop, variable pressure control technique is patented by Continental Controls and it offers a superior method for minimizing emissions.
