Web9 jan. 2024 · Otto cycle thermal efficiency potential = 1 – 1/CR^0.4, where CR is compression ratio. So for 7.8 compression ratio, thermal efficiency potential is 56%, for 12.5 CR it is 64%, i.e. a theoretical 14% increase in power and/or economy. This is why, for HE engines, Jaguar increased compression ratio up to 12.5. Web1.5M views 1 year ago Boost School In today's video we're talking about your engine's compression ratio.
