Dual-Fuel™ technology takes advantage of the inherent efficiencies of the compression stroke engine and dramatically reduces the consumption of diesel fuel, resulting in an engine that is more powerful and efficient than a dedicated spark-ignited natural gas engine and substantially reduces emissions. Dual-Fuel™ engines offer the best of both worlds with attractive maintenance costs and demonstrable return on investment. The benefits are substantial:

Cost Savings

• Lower operating cost than a diesel engine
• Better fuel economy than a dedicated natural gas engine
• Average in-service gas substitution rates: 75%
• Favourable payback periods
• Can be converted back to dedicated diesel, protecting its resale value

Power and Efficiency

• Power and efficiency equivalent to a diesel engine
• Operates at the same compression ratio as the diesel engine, un-throttled with lean-burn combustion

Low Emissions

• Emissions equivalent to a dedicated natural gas engine, with lower carbon dioxide emission (CO₂)
• Compared to the diesel engine, the Dual-Fuel™ engine delivers lower emissions of:
• Oxides of nitrogen (NOx)
• Particulate matter (PM)
• Soot (smoke)
• Carbon monoxide
• Non-methyl hydrocarbons
• Carbon dioxide (and total greenhouse gases)

Fuel Flexibility

• Dual-Fuel™ engines can operate on 100% diesel if gas is not available
• Dual-Fuel™ engines can operate on either liquid natural gas (LNG) or compressed natural gas (CNG) storage systems

Proven In-Field Operation

• Over 1,600 units proven worldwide over varied duty cycles and applications
• Global warranty and product support service
• Significant cost savings demonstrated by customers
