GENERAL DESCRIPTION The Mixing Venturi is a device designed to precisely mix the fuel and air to be admitted to gas engines. The Venturi also measures the air flow to the engine. It is used with the ECV5 Emissions Control Valve to replace the carburetor and pressure regulator on both Rich-Burn and Lean-Burn gas reciprocating engines. The VM-350 Mixing Venturi and the ECV5 can be used with any single- or dual-bank natural gas engine in any application where one or more carburetors are used to meter fuel. The fuel metering is very precise in the Venturi, which means engines using two or more carburetors can be balanced to provide the same air-fuel mixture from two or more Venturies. The ECV-5 Emissions Control Valve is used with an appropriate O2 sensor to precisely control the fuel mixture for compliance with the emissions regulations.
