HOW IT WORKS

Gas is mixed with air by a common mixer installed before the turbocharger(s). Gas flow is controlled by a throttle valve, which is electronically operated by the ComAp control system InteliDrive BF according to the required engine output and speed.

In order to avoid knocking of the engine, ComAp knocking detector/controller DENOX is installed, thus enabling engine operation at the most efficient gas/diesel ratio.

System for conversion of industrial diesel engines to bi–fuel operation by substitution of typically 50–80% natural gas for diesel.

• Suitable for all High Speed Engines, 1200–1800 RPM
• No reduction of engine power or efficiency
• Smooth transition between diesel and bi–fuel operations at any time
• Gas and air are blended behind air filter before turbocharger by central mixer
• State of the art electronics maximizes the amount of injected gas while keeping all engine parameters within limits specified by the engine manufacturer
• No modifications of internal engine components are required

MAIN FEATURES

• Completely automatic system
• Cheaper electricity production
• Non–derated output power
• The same response to load steps
• The amount of gas is maximized as much as possible under varying conditions at any time
• High stability and increased protection of the engine
• Lower emissions
• Possibility of pure diesel operation maintained
• Prolonged service intervals
• Turn-key solution
• Easy operation

TYPICAL CONVERTIBLE ENGINES

High-speed (1200 – 1800 rpm)

ELEMENTS OF THE SYSTEM

• Air / gas mixer(s)
• Gas throttle valve with actuator
• ComAp bi-fuel controller/governor InteliDrive BF
