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. WebThis paper reviews the results of various researchers from different countries who prepared biofuels from vegetable oils and animal fats. The performance and emission characteristics can be improved by blending with petrodiesel, changing the fuel injection parameters, adding oxygen-rich fuel additives and employing intake air oxygen enrichment methods.
