Compression ignition internal combustion engine using reactive agent

Abstract

The invention discloses a compression ignition internal combustion engine using a reactive agent. Gasoline or diesel oil or methyl alcohol of a gas station serves as fuel, diffusion compression ignition and homogeneous lean combustion control are achieved, the heat efficiency is larger than 45%, the specific oil consumption is smaller than 185 g / kwh, and NOX emission is close to zero. The reactiveagent (fuel additive) capable of reducing the octane number of the fuel is used as auxiliary fuel. The fuel and the auxiliary fuel are mixed into uniform ignition fuel in am ignition fuel mixer. Theignition fuel is injected into a cylinder in a compression stroke of the internal combustion engine and diffuses and spontaneously combusts in compressed air, multi-point ignition is achieved, and acting fuel is ignited. The acting fuel is injected into an air inlet channel in an air inlet stroke or injected into the cylinder to be premixed with air, and relatively uniform mixed gas is formed in the cylinder. The proportion of the ignition fuel in the fuel is about 3-10%. When 92# gasoline is used as fuel, the consumption of the auxiliary fuel is about 0.1% that of the fuel, and about 0.45 L of the auxiliary fuel is consumed when an automobile runs 10,000 kilometers.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines and fuels for internal combustion engines, in particular to a method for realizing compression ignition of internal combustion engines by using reactive agents and the internal combustion engines thereof. Background technique [0002] Common internal combustion engines are gasoline engines and diesel engines. [0003] Gasoline engine uses gasoline as fuel, uses spark plug to ignite, and burns homogeneously. The advantages of gasoline are low viscosity, fast evaporation, easy to mix evenly with air, and not easy to freeze in winter. The disadvantage of gasoline is that as a fuel for a compression-ignition internal combustion engine, its auto-ignition temperature is relatively high, and compression ignition cannot be achieved. The advantages of gasoline engines are small size, high power density, uniform combustion, and better emissions. The disadvantage of the gasoline engine...
