Project details

Short description

This collaboration project will conduct fundamental investigation on dual-fuel engines with different fuel combinations (port injection: natural gas or methanol, direct injection: e-fuels like dimethyl ether or polyoxymethylene dimethyl ethers). This project aims to reveal the in-cylinder mixing mechanism of different dual-fuel combinations, identify the effects of ambient conditions on the ignition limits of different dual-fuel mixtures, and clarify formation and quantity of combustion intermediate products at typical and extreme conditions. This research is also expected to develop methodologies for controllable ignition and combustion in dual-fuel engines and clarify the effects of engine intake and fuel supply strategies on their operation limits and combustion stability. Also, the collaboration is to analyze the energy conversion and distribution in the dual-fuel engine operation, and further provide a fuel efficiency optimization method in dual-fuel engines. Finally, reduction strategies for gaseous emissions and particulate number emissions of these low-carbon dual-fuel engines are to be studied and optimization strategies for efficiency improvement and emissions reduction are to be proposed.
