A new clean, efficient and environment-friendly gasoline product

Abstract

A clean, high efficient and environmentally friendly gasoline product with main fractions of C6-C11 has a low octane rating and a low spontaneous ignition temperature. It can be compressively ignited within an internal combustion engine with a compression ratio of 16-19. Small amount of ethanol or dimethyl ether can be added into the gasoline product.

Description

technical field [0001] The invention belongs to the technical field of petroleum refining and petrochemical industry, and is a new internal combustion engine fuel oil (refined oil) product. Background technique [0002] 1. Comparison of diesel engine and gasoline engine [0003] Gasoline engines generally inject gasoline into the intake pipe and mix it with air to form a combustible mixture, which then enters the cylinder, and is ignited by the spark plug to burn and expand to do work. People usually call it an ignition engine. Diesel engines generally spray diesel directly into the engine cylinder through fuel injection pumps and nozzles. The diesel is evenly mixed with the compressed air in the cylinder, and spontaneously ignites under high temperature and high pressure to push the piston to do work. People call this kind of engine a compression ignition engine. [0004] Usually, the thermal efficiency of a diesel engine is 30% higher than that of a gasoline engine. The...
