Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The starting point of engine braking is marked by a vertical green line, and the end point is marked by a vertical red line.

HyMethShip seeks to fuel ship engines with hydrogen from methanol

Green Car Congress

The EU-funded HyMethShip project developed a system that innovatively combined a membrane reactor, a CO 2 capture system, a storage system for CO 2 and methanol as well as a hydrogen-fueled combustion engine to power ships. The bottom part shows how hydrogen for the engine is obtained from methanol in the reactor (blue arrow).
