Bi Fuel Conversion Systems

Conversion Of Diesel Engines To Bi-Fuel ( Diesel And Gas ) Operation

Diesel engines users who have a suitable gas available can benefit now from the bi-fuel conversion technology .

What does bi-fuel operation actually mean?

Bi-fuel operation means the engine uses two fuels ( gas and diesel oil ) at the same time . Natural gas is intended as the main fuel and diesel oil is used for the ignition of the gas / air mixture inside the cylinder (a portion of diesel oil is injected at the end of the compression stroke , thereby maintaining the original diesel operation principle ). How it works?

Gas is mixed with air by a common mixer installed before turbocharger(s) . Gas flow is controlled by a throttle valve , which is electronically operated according to the required engine output and speed . In order to avoid knocking of the engine , knocking detector / controller is installed , thus enabling engine operation at the most efficient gas / diesel ratio .

General information

System for conversion of industrial diesel engines to bi-fuel operation by substitution of typically 50-80% natural gas for diesel system 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 Diesel Fuel are blended behind air filter before turbocharger by control mixer. The state of art electronics maximizes amount of injected gas while keeping all engine parameters in limits specified by engine manufacturer No modifications on internal engine components are required . Bi Fuel conversion is the process of converting normal diesel engines to utilize both gas fuel and diesel fuel at the same time. The main advantage is substantial reduction in diesel fuel consumption thus greatly reducing the running cost. " Power House " converts diesel engines to bi-fuel operation by
  • Individual gas – valve technology for slow and medium speed engines .
  • Central gas / air mixer for high speed engines .
