Energy-saving and environmental-friendly internal-combustion steam engine

Abstract

The invention discloses an energy-saving and environmental-friendly internal-combustion steam engine which relates to mechanisms such as cylinders, a piston, a machine body, a crankshaft connecting rod, and the like of the prior internal-combustion engine. The internal-combustion steam engine is characterized in that two cylinders, i.e. an internal-combustion cylinder and a stream cylinder are adopted as a unit and matched to finish a work doing process; the internal-combustion cylinder 22 and the stream cylinder 21 are arranged on a same crankshaft 20; an exhaust port of the internal-combustion cylinder and an air intake of the stream cylinder are connected through a channel 9; when an exhaust stroke is carried out after an internal-combustion cylinder piston 24 finishes air intake, compression and an expansion stroke, the steam cylinder simultaneously performs an intake stroke; all highly-heat waste gas enters the stream cylinder to compress so as to ensure that the temperature is raised once again; a water nozzle 2 sprays atomized water containing a catalytic reduction agent and a carbamide solution so as to evaporate, expand and push a piston 23 to do work; and exhaust steam is recovered through a cooler 14. The waste gas heat energy discharged after the internal-combustion engine does work can be sufficiently utilized and purified so as to save the energy and reduce exhaust amount. The environmental protection can reach a national IV standard, and the internal-combustion steam engine can be used for automobiles, steamships, trains, electricity generation, military use and other fields.

Description

1. Technical field [0001] The present invention relates to an internal combustion steam engine, in particular to a steam engine which adopts the cooperation of the internal gas cylinder and the steam cylinder, and compresses, sprays water, evaporates, and expands all the waste gas heat energy discharged after the internal gas cylinder does work in the steam cylinder, and then pushes the piston to do work and purify. , An energy-saving and environment-friendly internal combustion steam engine that cools and recovers steam for recycling. 2. Background technology [0002] Internal combustion engines are widely used in human beings, such as automobiles, trains, ships, power generation and other fields. Internal combustion engines are compressed, burned and expanded by fuel and air in the cylinder to push the piston to do work and exhaust exhaust gas, and a large amount of heat energy generated is not used and discharged. Exhaust gas contains a large amount of harmful gases such ...

Problems solved by technology

Air pollution and energy shortage have become a major problem in the world, and most of the pollution comes from internal combustion engines. Although the existing internal combustion engines have been improved many times, they are still not ideal

Patent No. CN200510044165.X's Chinese patent titled "six-stroke fuel-saving internal combustion engine" establishes two nozzles on the cylinder head, an oil nozzle and a water nozzle, so that the piston produces six strokes, i.e. three After one stroke, add a valve opening exhaust stroke, add a water spray vaporization power stroke, and add an exhaust stroke, which is similar to the six-stroke engine invented by American engineer Bruce Crower, which is to spray water after the exhaust stroke of the four-stroke engine. Into the cylinder to generate steam expansion to push the piston to do work, so that most of the heat energy has been discharged and only a small amount of heat energy is used, which is not very effective in terms of emission reduction and environmental protection
