Coal water slurry compression-ignition internal combustion engine

Abstract

A coal water slurry compression-ignition internal combustion engine relates to the fields of coal water slurry fuels, internal combustion engines, and air compressor components. The important components of the compression-ignition internal combustion engine are pistons 1, a round notched crank shaft 2, a crankshaft 3 and cylinder bodies 4, wherein the pistons 1 as well as the cylinder bodies 4 are arranged opposite horizontally; the round notched crank shaft 2 is embedded in the circular interior of the round notched crank hole 1-1 of the pistons 1; the notched crank groove 2-2 of the round notched crank shaft 2 is connected with the crankshaft 3 through a crank 3-1; the notched crank shaft 2 and the crankshaft 3 are integrally embedded in the cylinder bodies 4. The compression-ignition internal combustion engine adopts the design concept of an eccentric crankshaft of a rotary engine, so as to reduce vibration and friction of the crankshaft, and reduce length and diameter of the crankshaft by half, reduce the size of the internal combustion engine, and improve fuel economical efficiency to reduce fuel cost. The compression-ignition internal combustion engine is long in stroke, can realize the compression-ignition technology for various fuels to a diesel mode, and is particularly suitable for compression-ignition combustion of fuels such as gasoline, diesel oil, methanol and coal water slurry, thereby greatly improving combustion efficiency of the internal combustion engine.

Description

Technical field: [0001] The invention relates to the field of coal-water slurry fuel and internal combustion engine and the field of air compressor parts, in particular to coal-water slurry fuel, horizontally opposed piston, round notch crank, crankshaft and horizontally opposed cylinder of internal combustion engine and compressor. Background technique: [0002] The advent of coal water slurry originated from the world oil energy crisis in the 1970s. At that time, after the great economic recession caused by the oil energy crisis, the whole world clearly realized that oil and natural gas, as clean energy, were not inexhaustible, and abundant coal was still a long-term reliable main energy source. However, the historical lessons of severe air pollution caused by traditional coal burning cannot be repeated. Therefore, coal liquefaction, vaporization and pulping have become a research topic that advanced industrial countries generally attach importance to. Coal water slurry ...

AI Technical Summary

Problems solved by technology

[0003] The piston of the existing internal combustion engine is a separate individual piston, which is moved by the crank connecting the piston and the crankshaft. The mechanical wear is relatively large, and there are relatively many parts, which makes the crankshaft longer, with more crankshaft supports and relatively large volume. Therefore, the manufacturing cost is higher and the parts are more
