Heavy Duty Gas Engines integrated in vehicles
HDGAS (Heavy Duty Gas Engines integrated in Vehicles) is a three-year project responding to the Horizon 2020 Green Vehicles call in 2014 about future alternative powertrains for heavy duty vehicles. The overall project objective is to develop, demonstrate and optimize advanced powertrain concepts for dual-fuel and for pure natural gas operation engines, perform integration thereof into heavy duty vehicles, and confirm achievement of Euro VI emissions levels.
Specifically, Ricardo is developing a lean-burn direct-injection spark-ignited natural gas engine for the heavy duty on-highway market. In addition, the activity is investigating, developing, calibrating and testing advanced aftertreatment systems for natural gas powertrains to meet Euro VI.The project target is a 10% fuel economy improvement over a 2013 natural gas best-in-class engine. This equates to a fiscal reduction for end users, where fuel costs can approach 50% of the operational expenditure. With CO2 emissions reduction at ≥10%, the technology being developed in the project has the potential to avoid significant levels of CO2 emissions being produced.
The technology being developed by Ricardo and its partners consists of a high-tumble heavy-duty combustion chamber, lean-burn combustion with corona ignition system, and direct natural-gas injection, as well as a state-of-the-art methane oxidation catalyst to meet tailpipe methane targets.
