Abstract
The invention discloses an oil injection device of a diesel engine. The oil injection device comprises a cylinder sleeve, two pistons and two oil injectors, wherein two opposite pistons are arranged in the cylinder sleeve, the tops of the two opposite pistons form a combustion chamber; the two oil injectors are oppositely arranged on the two sides of the combustion chamber; and oil injection holes at one ends, extending into the cylinder sleeve, of the oil injectors are obliquely arranged toward an exhaust valve. According to the oil injection device of the diesel engine, the fuel oil in the cylinder can be uniformly mixed, benefit is brought to the combustion organization of the engine, the combustion efficiency is improved and the oil consumption is reduced.
Description
Technical field
The present invention relates to a kind of diesel engine fuel injecting device.
Background technique
The oil spout technology that current opposed piston internal combustion engine uses has single oil sprayer or multiple oil sprayer along cylinder circumferentially two kinds of forms, but reasonably organizes fuel distribution also to there is certain problem by the simplest structural type.The spray orifice form of existing oil sprayer cannot the fuel distribution of the flat firing chamber of rationalization's opposed piston type engine, well can not form the optimum Match of fuel oil, air, firing chamber.
In raising diesel powered field, generally only improve compression ratio, for strengthening air inflow, but excessive supercharging can make compression stroke lose power, and therefore effect is undesirable.What also have increases power by high speed, high temperature, and oil, when compressing terminal, is sprayed into cylinder inner carrier top by diesel engine, and oil starts distribution, and heating evaporation, is easily ignited by the spark plug after vaporization.When compressing terminal, in cylinder, temperature is about 450 degree, now exhaust valve temperature side has more than 1000 degree, thus exhaust valve is when compressing terminal, and oil is sprayed on piston top downwards by oil sprayer, thus does not use the temperature of exhaust valve, waste heat energy, and complex structure, not environmentally, fuel consumption is large for firing mode.
Summary of the invention
The technical solution adopted for the present invention to solve the technical problems is: a kind of diesel engine fuel injecting device, it comprises: cylinder sleeve, piston and oil sprayer, two opposed pistonss are provided with in cylinder sleeve, the top of this opposed pistons forms firing chamber jointly, it is characterized in that: the both sides of described firing chamber are opposite disposed two oil sprayers, and the nozzle opening described oil sprayer stretching into one end of cylinder sleeve inside is obliquely installed towards exhaust valve.
The invention has the beneficial effects as follows: the invention enables internal combustion oil of cylinder can realize uniform mixing, have the burning tissues utilizing contraposition engine, improve combustion efficiency, reduce oil consumption.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Accompanying drawing explanation
1, cylinder sleeve, 2, piston, 3, oil sprayer.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of diesel engine fuel injecting device as shown in Figure 1, it comprises: cylinder sleeve 1, piston 2 and oil sprayer 3, two opposed pistonss 2 are provided with in cylinder sleeve 1, the top of this opposed pistons 2 forms firing chamber jointly, it is characterized in that: the both sides of described firing chamber are opposite disposed two oil sprayers 3, and the nozzle opening described oil sprayer 3 stretching into one end of cylinder sleeve 1 inside is obliquely installed towards exhaust valve.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
