 Get to know Compressed natural gas (CNG) and conversion systems

Bi-Fuel or Switchable System

Bi-fuel system also called “switchable” system is a CNG Conversion which is only used for gasoline type engines. Through this conversion system the driver can freely switch the engine to run on gasoline or natural gas. No modifications were made to the engine. With the Bi-Fuel CNG system, natural gas is injected into the engine intake air in the same way that gasoline is injected into a gasoline type engine.

Thus, the engine will work in the same way a gasoline engine where the air-fuel mixture is compressed during the piston’s upstroke cycle and ignited by a spark plug where the gases increase mechanical energy in the form of rotation that propels the vehicle. Installation for the Bi Fuel conversion kit is quite simple, where it usually takes less than a day to install onto the vehicle. As information, iveco obd  easy to use in vehicles such as Iveco OBD port to connect a very useful error code eraser.

Due to the simplicity and cost of these injection-type gasoline converters, the cost ranges from US$500 – US$700 (excluding storage tanks), vehicle owners can easily derive maximum economic benefits from the conversion. The only drawback of this Bi Fuel is that because it is usually installed on small-medium size vehicles, the vehicle owner has to give up some of the space for the storage tank.

Dual Fuel System

The Dual Fuel System is mostly used only for diesel engine conversion. Through this conversion the diesel engine can use natural gas along with diesel fuel. This engine is essentially unchanged and continues to use diesel compression ignition for ignition of natural gas fuel. Unlike the dedicated system, where the engine can now only burn natural gas fuel, the engine’s dual fuel system will burn both fuel and diesel at the same time. the mixture of gas and diesel fuel when the truck is operating is highly dependent on factors such as road conditions, traffic conditions, driver behavior, engine performance, engine type ratio, etc.

The advantage of using dual fuel conversion is that the engine can still operate on 100% diesel fuel, or alternately, on a mixture of diesel fuel and natural gas. The disadvantage, however, is that vehicle owners may not be able to fully derive the economic benefits of the lower cost of CNG fuel because the engine will still require a diesel fuel mixture of 40% at best, to 100%. Depending on the size and type of diesel engine, this Custom Conversion System can range from US$4,500 – US$8,500 (excluding storage tank).

Mono or Custom Conversion System

Engines that are converted 100% to CNG are referred to as Mono or dedicated systems when the vehicle after conversion can only run on natural gas. Dedicated conversion is usually done for diesel type engines, where it can be done by replacing the entire engine block with a natural gas engine, known as Repowering, or the original engine itself through limited modifications to the engine, including the piston cylinder. And then, nox 5 emulator is the best part eraser is a standalone device.

The advantage of using this type of conversion is that the vehicle owner can reap the full economic benefits whenever natural gas is cheaper than alternative fuels. The disadvantage, because vehicles can no longer use other fuels other than natural gas, the availability of CNG stations must be available through driving coverage. Depending on the size and type of diesel engine, these Custom Conversion Systems can range from US$7,500 – US$15,000 (excluding storage tanks).
