Do High Compression Engines Need High Octane Fuel? Why?

Web3 de ago. de 2016 · So, in first part of the "compression" stroke, air is expelled back into intake manifold (so no compression actually takes place), then the valve closes and only the remaining part of the stroke actually compresses. This trick is used in so called "Atkinson cycle" engines that achieve better fuel efficiency at cost of lower power, eg in Prius. WebAn octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without detonating.The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit … Web5 de jun. de 2024 · The highest compression ratio for 87 octane is 10.7:1. This compares to other fuels such as gasoline which has a compression ratio of 14.7:1 and diesel which has a compression ratio of 18.3:1.

Compression Ratio and Coolant Temperature Effects on HC Emissions …

WebShort version: higher compression ratio means higher efficiency, so for the same amount of fuel in you can get more useful power out. Long version, which has a bunch of messy thermodynamics behind it. Higher compression means the charge is smaller when the piston is at the top, and that it's hotter and higher pressure during the power stroke. Web8 de abr. de 2024 · This higher heat of compression in the compression stroke will cause the compressor’s superheated discharge temperature to be higher.
