Libertine, demos hybrid ethanol tech for heavy duty vehicles : Biofuels Digest
With Libertine’s technology, hybrid heavy-duty powertrains using a combination of renewable grid power and renewable bioethanol fuel could offer OEMs a practical, cost effective solution to help achieve this vital transition to sustainable fuels and ‘net-zero’ (carbon neutrality). The project, supported by a grant from the UK Government’s Sustainable Innovation Fund, has shown how a ‘Free Piston’ engine can achieve an improvement in cold start performance using bioethanol by briefly increasing the compression ratio at startup, compensating for chamber wall cooling effects that co...
