High efficient natural gas engine concepts for long haul transportation

Description

Different natural gas engine technologies can be applied for commercial vehicles and those investigated in the HDGAS project are:
- Positive ignition natural gas engine with direct injection
- Dual fuel natural gas engine (premixed gas and pilot diesel injection)
- High pressure gas injection with pilot diesel injection
This paper will describe the challenges and solutions of the different engine concepts in combination with LNG tank systems in respect of
- Greenhouse gas reduction potential including measures to improve gas engine efficiency
- Emission compliance to EU VI
