In bi-fuel operation an engine uses gas and diesel at the same time, with natural gas the main fuel and diesel used for the ignition of the gas/air mixture inside the cylinder. Here, ComAp explores the five things you should know before deciding to use bi-fuel in your application.

1. Lower fuel costs

Up to 70 per cent of diesel consumption can be replaced by gas, which, due to the lower price of gas compared to diesel, allows for dramatically reduced operational costs.

2. Fuel flexibility

ComAp’s system allows for extended run-times without refuelling, without compromising the power output of the engine. It’s also possible to return to full-diesel mode at any time, with a smooth transition, with no loss of power.

As well as natural gas, (both tanked and mains supplied) the system can also use bio-gas, or even gas that is usually flared in mining or oil operations.

3. Environmentally friendly

The use of gas instead of diesel can give you a significant reduction in environmentally harmful emissions. Reduced emissions can include Nitrogen Dioxide, Sulphur Dioxide, and Carbon Dioxide, which can all be reduced by between five per cent and 40 per cent.

4. Adaptive system

ComAp’s system allows for fully automatic compensation for changes in gas quality (typical in Oil and Gas applications), gas pressure, and temperatures. This ensures the best performance in every situation, regardless of gas quality or temperature.

5. Multiple engine systems

ComAp has different bi-fuel systems available for different applications. InteliBiFuel Lite is designed for single speed engines with an output of up to 200kW. InteliBiFuel is suitable for any single speed engine with an output over 200kW. The latest product is InteliBiFuel Mobile, which is designed for any mobile, variable speed applications such as mine-haul and frack trucks.
