Bi Fuel Mixer : Diesel – Natural Gas Mixer Valve

Bi-fuel mixers are a component in the conversion kit used to add a secondary fuel source to a diesel engine. The entire conversion kit includes a gas train, air-gas mixer, fuel control valve and control panel. The mixer  is installed between the air intake and turbocharger and is connected to the gas train via the fuel control valve. The gas train feeds the air-gas mixer(s) via an infinitely adjustable throttle valve (butterfly-style) giving better control over the system than anything else on the market. OptiBlend® uses the fumigation method and Venturi-style mixers to introduce natural gas into the intake air of a diesel engine, ensuring natural gas is only ever drawn into the engine and is never forced in under pressure. This design is inherently safer because it cannot result in over-fueling the engine.

Bi Fuel Gas Train

The OptiBlend® bi-fuel gas train can be connected to gas sources such as liquefied or compressed natural gas, wellhead gas, methane, low/high BTU methane, hydrogen, propane, and bio-methane. A gas train assembly includes a filter, manual ball valve, lock-off solenoid and zero pressure regulator. The supply gas pressure must be in the 3–5 psi range, and a primary pressure regulator may be required to lower the supply pressure if it is over 5 psi. The filter prevents particulate contaminants that may be present in the supply gas stream from entering the gas train and engine. The gas lock-off solenoid is controlled by the Programmable Logic Controller (PLC). The last component in the train is the zero pressure regulator, which detects fluctuations in engine vacuum through the mixer to maintain atmospheric pressure and prevent over-fueling.

Installing OptiBlend Bi Fuel Mixer Valve and Gas Train

The OptiBlend® air-gas mixer is sized specific to your engine and application by our team of engineers. Proper system design of the dual fuel conversion kit ensures site installation, start-up, and tuning phases go smoothly.

Good news…you don’t have to go to the Netherlands to access a #dualfuel system…

Did you know that Optiblend can be used

Optiblend was developed using pipeline natural gas and syngas. It has also been used with propane, LNG, and biogas.
