The environmental friendly vehicle light hydrocarbon fuel containing the surface active increased superscript agent can increase, without limitation, auto-ignition temperature of the fuel, improve distillation range distribution of the fuel, increase burning rate of the fuel, enhance power and reduce abrasion of an engine, avoid the formation of piston carbon, and lower consumption of the fuel, with a calorific value≧42000 kJ/kg, being a novel substitute vehicle fuel that is energy saving, environmental friendly, and cost effective.
The contents of the exhaust pollutants of the environmental friendly vehicle light hydrocarbon fuel according to the present invention, are much lower than the P.R.C. GB18352.3-2005 National Standard requirement (Limits and Measurement Methods for Emissions from Light-Duty Vehicles), based on test of contents of the exhaust pollutants CO, HC, and NOx.
The surface active increased superscript agent can be substituted by the following components {circle around (8)}, {circle around (9)}, {circle around (10)}, or mixture thereof, in the environmental friendly vehicle light hydrocarbon fuel according to the present invention, so as to reduce the cost:
