Embodiment 1

[0012] See attached figure 1 , mainly composed of water tank 1, water pump 2, pressure regulator 3, electric control nozzle 4, electric control nozzle 5, intake pipe 6, exhaust pipe 7, intake valve 8, exhaust valve 9, piston 10, connecting rod 11, Compositions such as fuselage 12, machine base 13 (due to four-stroke gasoline engine and diesel engine oil supply system are different, do not mark among the figure).

[0013] The water tank 1, the water pump 2, and the pressure regulator 3 generate stable water pressure. When the piston of the internal combustion engine runs to the exhaust stroke, through the electronically controlled nozzles 4 and 5, water is regularly sprayed to the top of the moving piston, and the water vapor evaporated by heat Helps expel exhaust gases from the combustion chamber. After the exhaust is completed, the water vapor left in the combustion chamber will be decomposed into hydrogen and oxygen under the action of high temperature and high pressure whe...

Embodiment 2

[0015] See attached figure 2 , mainly consists of water tank 1, water pump 2, high-pressure water pump 3, nozzle 4, nozzle 5, intake pipe 6, exhaust pipe 7, intake valve 8, exhaust valve 9, piston 10, connecting rod 11, body 12, machine Seat 13 etc. are formed (due to four-stroke gasoline engine and diesel engine oil supply system are different, do not mark among the figure).

[0016] The water tank 1 and the water pump 2 send water to the high-pressure water pump 3. After the expansion stroke of the internal combustion engine is almost finished and the exhaust valve is opened, the water pressure is rapidly increased through the high-pressure water pump 3. When the water pressure is greater than the spring force inside the nozzle 4 , the needle valve inside the nozzle 4 is jacked up, and the high-pressure water is sprayed out through the small hole on the nozzle (the same is true for the nozzle 5). Water is regularly sprayed to the top of the moving piston, and the heated an...

Embodiment 3

[0018] See attached image 3 , mainly composed of water tank 1, water pump 2, high-pressure water pump 3, nozzle 4, nozzle 5, scavenging air port 6, exhaust pipe 7, scavenging air box 8, exhaust valve 9, piston 10, connecting rod 11, body 12, machine Seat 13 etc. are formed (due to two-stroke gasoline engine and diesel engine oil supply system are different, do not mark among the figure).

[0019] The water tank 1 and the water pump 2 send water to the high-pressure water pump 3. The combustion expansion of the internal combustion engine and the exhaust scavenging stroke, when the exhaust valve is opened and before the scavenging port is opened, the water pressure is rapidly increased by the high-pressure water pump 3. When the water pressure was greater than the spring force inside the nozzle 4, the needle valve inside the nozzle 4 was lifted up, and the high-pressure water was ejected through the small hole on the nozzle (the same is true for the nozzle 5). Water is regular...

Abstract

The invention discloses water-spraying and exhaust-assisting energy-saving and emission-reduction method and device for internal combustion engine, which overcomes the problem that the internal combustion engine can not completely discharge waste gas, utilizes a water tank, a water pump, a nozzle and the like, and is characterized in that during the process that the exhaust valve of the internal combustion engine is turned on, water is sprayed to the top of a piston through the nozzle at regular time; water vapor evaporating by being heated helps to completely discharge waste gas in a combustion chamber, and the water vapor remained in the combustion chamber is decomposed into hydrogen and oxygen under the action of high temperature and high voltage when combustion explosion occurs in the combustion chamber, thus greatly improving combustion condition. The method has wide application scope, simple structure, and good energy-saving and emission-reduction effect.

Description

technical field [0001] The invention relates to an energy-saving and emission-reducing method and device for water spraying to assist exhaust, in particular to an energy-saving and emission-reducing method and device for internal combustion engine to spray water to assist exhaust. Background technique [0002] Since the piston internal combustion engine came out in the 1860s, it has been a relatively complete power machine through continuous improvement and development. It has been widely used due to its high thermal efficiency, wide range of power and speed, convenient matching and good maneuverability. Various types of automobiles, agricultural machinery, construction machinery, small mobile power stations and chariots all over the world are powered by internal combustion engines. Merchant ships at sea, inland watercraft and conventional ships, and some small aircraft are also propelled by internal combustion engines. The number of internal combustion engines in the worl...
