Dual-Fuel™ Engine Technology Facts:
- Engine runs on natural gas with diesel pilot ignition
- At full power diesel fuel is 10% of total fuel - normal operation is up to 85% natural gas substitution
- Runs on 100% diesel fuel until engine coolant is at operating temperature
- Under normal operation, can run solely on diesel at light loads*
- Under normal operation, can run solely on diesel at full power*
- Uses a standard electronically-controlled diesel engine
- Maintains electronic control of both gas and diesel injection
- Base diesel ECU is retained
- Dual-Fuel™ ECU controls gas operation and modifies diesel demand for the diesel engine ECU
- Automatically reverts to diesel only when gas supply is out of acceptable parameters
- Recent introduction of a combustion knock sensor protects the engine from variable gas quality
| * | The operating system in the technology automatically switches the engine from diesel to natural gas when the truck reaches optimal load, making it particularly suited to long haul heavy trucks. Dual-Fuel™ can be turned off at any time, enabling the engine to operate totally on diesel. This switch from diesel, or to dual fuel is almost imperceptible, even while the vehicle is moving. |
