Description

A kind of internal-combustion engine auxiliary combustion equipment

The utility model relates to a kind of auxiliary combustion equipment, especially a kind of internal-combustion engine auxiliary combustion equipment that improves combustion in IC engine speed.

For improving the combustion efficiency of internal-combustion engine, save fuel oil, reduce the harmful components in the effulent, method commonly used in the prior art has: forcing increases cylinder intake air quantity, perhaps allows together spray in the cylinder after methyl alcohol and the air mixing, perhaps oil emulsion is sprayed into cylinder or the like, but all can not effectively improve combustion efficiency, but also cause complex structure, make difficulty, the high deficiency of cost.Chinese patent discloses the utility model patent of a kind of " internal-combustion engine blower " in addition, its patent No. is 90225014.0, it is as oxidizer with oxygen, and set up oxygen cylinder and various instrument etc., not only cost increases, but also has unsafe factor, therefore, do not adapt to high efficiency, low energy consumption, highly reliable, and the needs of the environmentally friendly modern life.Must make improvement to prior art.

The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of simple in structure, can effectively improve the internal-combustion engine auxiliary combustion equipment of combustion efficiency.

The technical solution of the utility model is: it comprises cylinder and cylinder head, timing-gear chamber cover and camshaft, it is characterized in that be provided with combustion-supporting driving cam on the camshaft and be attached thereto and be located at the combustion-supporting pump of high pressure that timing gear cover and be located at cylinder head on and the oxidizer sparger that links to each other by the combustion-supporting pump of pipeline and high pressure.Described oxidizer sparger and oil sprayer constitute 10-50 ° of angle, so as before injection advance angle or ignition advance angle in 10 degree or the back 30 degree scopes to the in-cylinder injection oxidizer, promote the abundant burning of fuel oil, effectively reduce oil consumption and effulent thereof.Described combustion-supporting driving cam and the camshaft that links to each other with the combustion-supporting pump of high pressure constitutes an integral body, perhaps is movably arranged on the camshaft, so that adjust corner as required.

The utility model compared with prior art has following advantage and good effect: owing to set up the oxidizer sparger on cylinder, and drive driving cam by the rotation of camshaft, make the oxidizer in the combustion-supporting pump produce high pressure, thereby the high pressure oxidizer is sprayed into participation burning in the cylinder, promote the abundant burning of fuel oil, effectively improve power of IC engine, reduced the consumption and the discharging of fuel oil.Other the utlity model has simple in structure, and cost is low, and characteristics such as efficient height are applicable to various internal-combustion engines, and real is internal-combustion engine auxiliary combustion equipment of new generation.

Fig. 1 is the emitter construction schematic representation of the utility model;

Fig. 2 is the suction booster structural representation of the utility model.

Below in conjunction with accompanying drawing the utility model is described further, is not limited to this but hold within the utility model.

Among the figure, 1 is the cylinder body, 2 is cylinder liner, and 3 is cylinder, and 4 is cylinder head, 5 is the oxidizer sparger, the oil sprayer 6 of itself and horizontal position constitutes 30 ° tilt angle, and the entry end 7 of this sparger links to each other with the outlet of the combustion-supporting pump 9 of high pressure by pipeline 8, and 6 is oil sprayer, 9 is the combustion-supporting pump of high pressure, inlet 10 on it is used for providing oxidizer in it, the combustion-supporting pump of this high pressure is installed on the Timing gear cover 11, and makes oxidizer supercharging in it by driving cam 12, described driving cam 12 is installed on the camshaft 13,14 is cam of injection pump, and 15 is oil pump, is installed on the Timing gear cover 11,16 is oil-feed port, and its outlet links to each other with the inlet A end of oil sprayer 6 by pipeline 17.When internal combustion engine, rotation by camshaft 13 drives cam of injection pump 14 rotations, thereby the fuel oil in the oil pump 15 is carried out supercharging, and high pressure fuel is delivered to oil sprayer 6 by pipeline 17, so that to the in-cylinder injection high pressure fuel, when camshaft 13 rotates, by the oxidizer supercharging in 12 pairs of combustion-supporting pumps 9 of driving cam, by pipeline 8 the high pressure oxidizer is delivered in the sparger 5 again, so that in the spray fuel oil, to the in-cylinder injection oxidizer.
