The Japanese producer is working on a new motor which has reached 50 % thermal efficiency in examining
Petrol engines are in fact pretty wasteful. The majority of the power generated from the combustion period goes to waste through temperature and sound in however, most efficient power plants, yet there are improvements to be produced on this front in ICE’s twilight years.
Nissan is cooking upward a new engine that has currently achieved 50 per cent heat efficiency in testing. For many people reading this, some framework is required, which we can provide via the 1 . 6-litre turbo charged V6 used by the Mercedes-AMG F1 team. It’s probably the most thermally efficient internal combustable engine produced thus far, and in addition it manages 50 per cent heat efficiency.
Probably the most thermally efficient production powerplants out there meanwhile is Toyota ‘s ‘Dynamic Force’ motor, which manages 41 %. We should imagine Mazda’s spark-controlled compression ignition SkyActiv-X unit at least manages an identical figure, potentially a better 1 (we’ve asked Mazda UNITED KINGDOM if it can reveal several numbers).
fifty per cent, then, is an amazing achievement. The number isn’t completely comparable, however , and as just for why, the clue’s within the branding – ‘e-Power’. The particular engine won’t directly energy the wheels – it is instead used as an electrical generator for an electric motor. This enables it to stay at the best engine speeds for the best trade-off between power and performance.
Like the SkyActiv-X engine (above), Nissan’s brand new powerplant uses a high data compresion ratio to combust the lean fuel/air mixture. Upon that subject, Mazda mentioned a few years ago that it was focusing on something called ‘SkyActiv-3’, that could reach a staggering 56 percent efficiency, rivalling the exhausts of some fully electric powered cars depending on the charge supply.
We do not know when either SkyActiv-3 or this new edition of Nissan’s e-Power can reach production. Regardless, it is interesting to see that the very humble petrol engine still includes a few tricks up the sleeve while manufacturers convert their attention to batteries plus motors.
