Steam internal-combustion engine

Abstract

The invention provides a steam internal-combustion engine, which replaces a spark plug of ordinary internal-combustion engine with a water injection spark plug, if an engine reaches the preset temperature limit, when the fuel combustion cycle starts, the water injection spark plug injects a small amount of water close to boiling point to a combustion chamber. A steam internal-combustion engine controller monitors the temperature of the engine, receives and changes the oil-injection pressure, starts and closes a water injection solenoid valve, and controls the water injection volume accurately. The steam internal-combustion engine provided by the invention can changes the ordinary automobile into a steam internal-combustion locomotive, can change water into hot water through effectively utilizing waste heat from combustion and discharge, and then changes the hot water into steam; the generated additional useful work pushes a piston, thereby reducing the consumption and emissions of fuel oil. The efficiency of the steam internal-combustion engine is of 40%, and is not 20% of the existing internal-combustion engine. The steam internal-combustion engine provided by the invention can be used for not only most automobiles but also any otto cycle (Otto Cycle) internal combustion engine, such as, the generator, the lawn mower and the like.

Description

technical field [0001] The invention belongs to the field of internal combustion locomotives, in particular to a steam internal combustion engine. Background technique [0002] Internal combustion engines have been the main source of power for motor vehicles for the past hundred years, and a typical internal combustion engine consists of more than one piston-cylinder group. During the intake stroke, the air-fuel mixture is forced into the cylinder, compressed, then ignited and generates high pressure creating kinetic energy and waste heat. Because this process produces a large amount of waste heat, the efficiency of the internal combustion engine is relatively low, generally around 20%. [0003] There have been many attempts to convert this waste heat into mechanical energy. These examples include six-stroke internal combustion engines, which inject water into the combustion chamber to increase one power stroke. However, the power effect of water injection is very limited. ...

AI Technical Summary

Problems solved by technology

It improves the so-called urban kilometers per gallon, however, it does not directly address the fundamental problem of using the waste heat of the internal combustion engine, so it can be said that hybrid vehicles do not improve the actual efficiency of the internal combustion engine at all

[0006] In U.S. Patent No. 7,367,306, Holden introduced a fuel-water mixture injector for internal combustion engines, but it required major modifications to the original fuel injector, a critical and expensive component in the vehicle; meanwhile, Due to the small space of the injector itself, it is often difficult to reassemble it back into the current car, and it also lacks a feedback mechanism to adjust the amount of water sprayed, so it does not fully improve the efficiency of the engine
