HDGAS Unites 19 Partners For HD Natural Gas Powertrain Project

| Europe

HDGAS Partners 2015Partners in the European Commission’s Horizon 2020 Green Vehicle Initiative project ‘HDGAS’ – a project that aims to develop, demonstrate and optimize advanced powertrain concepts for dual-fuel and pure natural gas powered heavy duty vehicles, have been announced. Partners derive from Sweden, Finland, United Kingdom, The Netherlands, Germany, Austria, Italy and Spain and include OEMs Daimler, Iveco, MAN and Volvo.

Long haul trucks are an essential element of the transportation mix of modern, industrialized society. The primary objectives of HDGAS are to deliver improved fuel efficiency and reduced greenhouse gas emissions for this sector whilst also meeting current Euro VI emissions standards. It aims to develop technologies to address this need whilst also meeting or exceeding the latest Euro VI regulated emissions standards, as well as achieving in-use compliance under real-world driving conditions and CO2 or greenhouse gas emissions reduction.

HDGAS imageThe developed components and technologies will be integrated into three demonstration vehicles that are representative for long haul heavy duty  vehicles in the 40 ton range. The demonstration vehicles will:

  • comply with the Euro VI emission regulations;
  • meet at minimum 10% CO2 reduction compared to state of the art technology;
  • show a range before fueling of at least 800 km on natural gas;
  • be competitive in terms of performance, engine life, cost of ownership, safety and comport to 2013 best in class vehicles.

Ricardo is one of 19 collaborating EU commercial and academic partners on the HDGAS project. Particular areas of focus for the company will be the development of engine and aftertreatment systems that offer the prospect of delivering real driving emissions well below Euro VI limits for heavy duty vehicles. Specifically, the aim of the new systems is to demonstrate improvements in the region of ten percent in torque, power, fuel efficiency and GHG emissions reduction. Through extensive use of simulation methods, Ricardo aims to create a heavy duty natural gas version of its direct injection combustion system that has already been used to great effect in ultra-clean gasoline engines. Technologies that will be investigated in this endeavour include a conceptual study of liquid natural gas direct injection and the application of high energy ignition system based on corona discharge.

Advanced dual-fuel and pure natural gas aftertreatment specification, development and testing is also a critical part the work of the HDGAS project, and an area where Ricardo will lead several partners of the consortium. This work will aim to provide important knowledge around the challenge of controlling tailpipe methane emissions and the impact of natural gas on some of the conventional aftertreatment technologies that might be applied, such as the risk of methane poisoning of SCR catalysts. Having specified the system requirements based on simulation and analysis, this information will be used as the basis for rig testing and development followed by incorporation of the technology on the four new heavy duty natural gas powertrains developed within the project. These will include the Ricardo lean burn direct injection engine and the three other engines being developed by the partners on the project. Ricardo will then complete a Euro VI calibration of the aftertreatment system on the lean burn engine.

“For future heavy commercial vehicles, reducing greenhouse gas emissions is a critical priority,” commented Dr Andrew Noble, Ricardo head of heavy duty engines. “A promising route towards this goal is the more widespread use of natural gas as an alternative to conventional liquid fossil fuels such as diesel. However, the adoption of natural gas power for commercial vehicles faces several technical challenges which are being addressed by the HDGAS project. Ricardo is very pleased to be a partner in HDGAS, contributing innovative technologies in collaboration with the other partners. We look forward to working towards the goal of demonstrating efficient lean burn engines and aftertreatment systems for all the candidate mono- and dual-fuel natural gas engine types.”
