Heavy Duty Engines
While there is significant research and development on alternative and renewable fuels undertaken worldwide, there are currently few market-ready clean fuel alternatives for heavy transport or stationary applications. Fewer still are alternative fuels that do not compete with food production, or, that can be deployed without major infrastructure development.
Natural gas is the fuel of choice for Trigeneration or remote power applications, either through a reticulated network, or transported to site as bulk LNG.
Propane (LPG) is the most widely used alternative vehicle fuel in Australia serviced by a well developed and distributed infrastructure. Melbourne’s taxi fleet operates on LPG, an option increasingly taken up by private users.
Bennett Clayton Engines are multi fuel capable, and can be specified for LPG, Natural Gas, Ethanol, Methanol, or Biogas applications.
Compared to ultra-low sulphur diesel,
- 90% to 99% less oxides of nitrogen (NOx),
- 80% to 95% less particles,
- 99% to 99.8% less ultra-fine particles
The European Test Programme 2003 compared emissions of 26 vehicle types using petrol, diesel and LPG variants. Tests were conducted to EURO3 certification test cycles and measured pollutants regulated under EURO3 including PM, NOx, HC and CO.
The US Department of Energy analysed “total life-cycle” greenhouse emissions relative to petrol:

While the emissions argument for the adoption alternatives has been self-evident for some time, the economic arguments have not been so obvious in a climate where diesel prices were relatively low.
- Maintenance costs and engine life are enhanced
- Fuel Security
- Escalating Energy Costs
- Reduced downstream health and remediation costs
Bennett Clayton technology, implemented to rigorous engineering and quality standards, enables gas powered engines to meet all operational and power requirements of duty-rated engine applications.
