CO2 neutral heavy-duty engine concept with RCCI combustion using seaweed-based fuels
This paper focusses on the application of bioalcohols (ethanol, butanol) derived from seaweed in Heavy Duty (HD) Compression Ignition (CI) combustion engines. Seaweed based fuels don’t claim land and are not in competition with the food chain. Currently, the application of high octane bioalcohols is limited to SI engines. The Reactivity Controlled Compression Ignition (RCCI) combustion concept allows using these low carbon bioalcohol fuels in CI engines with associated higher than SI engine-like efficiencies. This contributes to reducing tailpipe CO2 emissions as is required by (future) legislation and reducing fuel consumption, i.e. Total-Cost-of-Ownership (TCO). Furthermore, it opens the HD transport market for these low carbon bioalcohol fuels from a novel sustainable biomass source .
