DieselGas develop alternative fuels engines. This includes dual fuel engine and dedicated gas engines, engine controllers and specialist gas engine components for low emissions engine.


dual fuel engines

Dual fuel engines are diesel engines that operate using diesel for pilot ignition with the main power coming from compressed natural gas (CNG). Over 22 years DieselGas has developed more than 20 different dual fuel engine types.The DieselGas dual fuel system uses the ST10 engine management controller and DGTech technician interface with mostly purpose designed built hardware components. Each different engine type requires an application engineering development process (see Dual fuel engine development) that allows the engine to operate at 90% gas at full load and meet strict emissions standards.

Dedicated gas engines

Dedicated gas engines are diesel engines that have been modified to operate on natural gas as a single fuel. The engine modifications are significant in that pistons, cylinder head and distributor drives design need to be changed. Dedicated gas engines use the DieselGas ST10 engine management controller and DGTech technician interface along with with mostly purpose designed built hardware components. Lean burn or stoichiometric combustion technology can be used, with or without a catalyst, depending on the emissions and fuel efficiency requirements. Each different engine type requires an application engineering development process (see Dedicated engine development). [more]


Engine controllers

DieselGas maintains electronic hardware and software development capability in house. The SGS Thompson ST10 269 microprocessor used in all DieselGas engine management controllers was develop by the DieselGas team. The DGTech technician interface GUI programme has also been developed by DieselGas. The DGTech graphical interface programme allows technicians to analyse, automatically generated, fault logs and diagnostic logs. Historical and driving cycle data can also be analysed and communicated electronically to the DieselGas factory.DieselGas can offer this engine management system and the development capability to engine manufacturers for alternative fuels or diesel engine applications.

Dual fuel power generation

Electric power generation using purpose built dual fuel engines has been available for many decades. DieselGas has applied its dual fuel technology to existing diesel generators to allow them to operate using pilot diesel for ignition with the power coming from natural gas.The system can be interfaced for grid or stand alone applications with 90% substitution and diesel equivalent fuel efficiency possible in most cases.

Components

DieselGas engine management technology always incorporates the DieselGas microprocessor engine controller. Other components such as gas injection vales, air fuel ratio control throttle bodies, temperature sensors and diesel actuator components are purpose designed and built in house.

Components such as primary gas regulators and pressure sensors are purchased from reputable component suppliers. [more]
