Definition and synonyms of boost from the online English dictionary from Macmillan Education. Derive the mask of High-boost filter. One core would hit 3.6, but all six might only go up to 3.4 GHz when Turbo Boost is activated. How well an engine can convert the heat (thermal energy) into power (kinetic energy) is quantified by an engine’s thermal efficiency. Knock occurs when the fuel-air mixture in the cylinder doesn’t experience an ideal burn (the process of combustion). Even the name “titanium” sounds cool. Looking back nearly 50 years ago, Chevrolet reigned supreme when its ultra- high-performance, 283-cubic-inch small block generated an unprecedented 283 horsepower—one horsepower per cubic inch. However, the relationship among compression ratio, boost pressure, detonation and fuel octane is one that will always remain. However, having a fuel with a burn rate that is too slow can make your engine lose power. As the name indicates, the compression ratio of an engine indicates how much the air-fuel charge is compressed during the compression stroke of the four-stroke process. High boost pressures with high compression ratios. During detonation or knock the burn rate will see a violent 2000 feet per second explosion instead of a burn.
