Abstract
The utility model relates to a special water tank for an in-cylinder water injection engine, which comprises a water tank body. The special water tank is characterized in that: the special water tank also comprises a water pipe, one section of the water pipe is positioned in the water tank body, and both ends of the water pipe penetrate out of the water tank body and are respectively communicated with a coolant circulation water pipe of an engine; the section of the water pipe positioned in the water tank body presents an helix shape. When the special water tank is adopted, the coolant came from an engine cooling system carries out heat exchange in the water tank body which is used for containing water jetted into a cylinder and heats water jetted into the cylinder. Compared with a common water tank, the special water tank not only can ensure the regular service of an in-cylinder water injection device in the condition of frozen environment in northern winter but also can lighten the heat radiation load of the engine cooling system, thereby water jetted into the cylinder is quickly evaporated so that the time of liquid water existing in the cylinder is shortened, and the possibility that parts in cylinder are eroded the by liquid water is lowered; the consumed energy used for heating water jetted into the cylinder with the gas in the cylinder is reduced, so that more energy is used for doing work for water evaporation and expansion.
Description
Technical field
The utility model belongs to field of internal combustion engine---and the annex of combustion engine relates to a kind of in-cylinder water injection engine special water box.
Background technique
The name of submitting simultaneously with the application is called the utility application of " 4 stroke petrol engine inner-vat sprinkler ", a kind of ECU (Electrical Control Unit) that comprises is provided, water tank, 4 stroke petrol engine inner-vat sprinklers of forming by water pump, water rail and the water spout etc. of the control of described ECU (Electrical Control Unit); The water outlet of water pump is communicated with by the water intake of water pipe with the water rail in this inner-vat sprinkler, and water spout is connected with water outlet, water tank and the water pump of water rail by water pipe respectively, and it is indoor that the water orifice of water spout stretches into petrol engine combustion.
Existing vehicular engine---petrol engine, generally all use the pump circulation water-cooled, cooling system is mainly by the water channel in cylinder body, the cylinder cap, compositions such as water pump, radiator (water tank), fan, connection water pipe, cooling liquid in the water channel is taken away the heat that gives out in the cylinder, avoids engine overheat; Early stage cooling liquid directly makes water, and present most vehicles use antifreeze liquid as cooling liquid, and antifreeze liquid can be avoided freezing at north of china in winter, radiating effect even be better than using merely water-cooled; The cooling liquid radiating and cooling of higher temperature after water channel recycle.
Above-mentioned " 4 stroke petrol engine inner-vat sprinkler " in use, the water that sprays in the cylinder should not add antifreeze liquid, if adopt common water tank to be filled with water, and the interior water freezing of north water tank in winter, to cause inner-vat sprinkler to use, reduce the auxiliary practical usefulness of doing power engine of in-cylinder water injection.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned deficiency of the prior art, by the liquid circulation water pipe is passed tank box, the water in the tank box can be heated, guarantees " 4 stroke petrol engine inner-vat sprinkler " can normally use, the in-cylinder water injection engine special water box of energy efficiency thereby provide a kind of.
Content of the present invention is: a kind of in-cylinder water injection engine special water box, comprise: tank box, it is characterized in that: also comprise a water pipe (2), a section of this water pipe (2) is positioned at described tank box (6), two ends and passes tank box (6) and be connected with the liquid circulation water pipe of motor respectively; This water pipe (2) can be connected with liquid circulation water pipe in the engine-cooling system from the water channel of the water channel of the water channel of the water channel of the cylinder cap front end on the motor, cylinder cap rear end, body front end or body rear end or cooling system water tank etc.
In the content of the present invention: a section of tank box (6) of being positioned at of described water pipe (2) is preferably shape in the shape of a spiral, is beneficial to heat exchange.
Compared with prior art, the present invention has following characteristics and beneficial effect:
(1) adopts the utility model, the cooling liquid that attracts from engine-cooling system, cooling liquid with spray under the non-touching situation of water in the cylinder, reduce coolant temperature, raising need spray into the temperature of the water in the cylinder, by carrying out heat exchange in the employed tank box of the water in spraying into cylinder, for the water that sprays in the cylinder is heated; Compare with common water tank, not only under the environment of northern ice up in winter, guarantee that " 4 stroke petrol engine inner-vat sprinkler " can normally use, but also can bring the added advantage of three aspects: alleviate engine-cooling system heat radiation load; Help water and spray into the faster vaporization of cylinder, shorten the time that liquid water exists in cylinder, reduce the possibility of part in the liquid water corrosion cylinder; Reducing gas in the jar is to add to hold the spent energy of water that sprays in the cylinder, makes more heat be used to water vapor expansion acting;
(2) adopt the utility model, the water that sprays in the cylinder is heated rapidly in tank box, as in north winter, after automobile is parked for a long time, the water that sprays in the cylinder may freeze, and by this mode ice is melted rapidly, makes inner-vat sprinkler enter normal working; Water is heated before spurting into cylinder, sprays in the cylinder to vaporize rapidly, avoids the part corrosion that exists liquid water to cause piston, piston ring, valve, air valve seat ring, spark plug in the cylinder; Spray into after the heating in the cylinder, can reduce heating liquid water institute calorific requirement, more heat is used for water vapor expansion acting;
(3) simple in structure, produce easy to install, practical.
Description of drawings
Fig. 1 is the utility model embodiment user mode structural representation.
Among the figure: 1-motor, 2-are connected high-pressure water pipe, 4-return pipe, 5-water (being used for directly spraying into cylinder), 6-tank box, the 7-high-pressure water pump of high-pressure water pump and water rail with water pipe, the 3-that the engine coolant circulating pipe is communicated with.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Embodiment 1: referring to accompanying drawing.
A kind of in-cylinder water injection engine special water box is made up of tank box 6 and water pipe 2, and a section of this water pipe 2 is positioned at tank box 6, two ends and passes tank box 6 and be connected with the liquid circulation water pipe of motor respectively; This water pipe 2 can be connected with liquid circulation water pipe in the engine-cooling system from the water channel of the water channel of the water channel of the water channel of the cylinder cap front end on the motor, cylinder cap rear end, body front end or body rear end or cooling system water tank etc.; Water pipe 2 be positioned at one section of tank box 6 shape in the shape of a spiral, be beneficial to heat exchange.
During use, inject the water 5 that is used to spurt into cylinder in the tank box 6; After the engine start, engine temperature rises, in the cooling waterpump drive liquid circulation of in-engine cooling system; Cooling liquid in the liquid circulation water pipe 2 of drawing from motor begins to flow, and brings the heat that produces in the motor into tank box 6, is used to spurt into the water 5 of cylinder in the heating water chamber casing 6.High-pressure water pump 7 in " 4 stroke petrol engine inner-vat sprinkler " can place liquid circulation water pipe 2 central authorities, is heated as early as possible before spurting into cylinder and keeps higher relatively temperature to guarantee water spray.
