The gasoline injection device of the engine comprises cylinder covers matched with diesel engine cylinder blocks, wherein injecting rail seats are arranged on the cylinder covers. Nozzles connected with gasoline pumps are fixed on the injecting rail seats, and the number of the injecting rail seats coincides with the number of engine air cylinders. Center holes of the injecting rail seats are respectively communicated with air inlets of the diesel engine. The nozzles are arranged in an inclined mode, and injecting included angles of the nozzles are uniform with injecting included angles of the gasoline engine. Injecting devices are arranged on the cylinder covers of the engine, so that injecting requirements of gasoline are met. Besides, the gasoline injection device of the engine has the advantages that original components of the diesel engine are reasonably used, cost is saved, and working efficiency is improved.
Description
Technical field
The diesel engine that relates to the utility model repacks petrolic technical field into, particularly the gasoline injection system of motor.
Background technique
At present, domestic still have a lot of old machines to use diesel engine, but the noise of well-known diesel engine is big, seriously polluted, so now a lot of enterprises want diesel engine is replaced with petrol engine, particularly mostly the state-run enterprise of those old types, agricultural, engineering machinery are to adopt diesel engine, if will start whole replacings, must need substantial contribution to buy new engine, increase cost of production, simultaneously also can cause a large amount of diesel engine to be left unused, also waste original diesel engine money.At present more thirst for reequiping on the basis of original diesel engine, but because that the some combustion technology of gasoline and diesel engine are lighted principle is different, generally understanding is that diesel engine is compression ignite, petrol engine is a combustion technology, therefore need increase the device of injected petrol in original diesel engine, this brings certain degree of difficulty for the repacking of diesel engine.
Summary of the invention
The purpose of this utility model provides a kind of low cost of manufacture, be convenient to diesel engine repack the gasoline injection system of petrolic motor into.
For achieving the above object, the utility model has adopted following technological scheme: a kind of gasoline injection system of motor, comprise the cylinder cap that cooperates with diesel motor cylinder, described cylinder cap is provided with the spray rail chair, connect petrol pump nozzle be fixed on the spray rail chair, the quantity of described spray rail chair and number of engine cylinders are coincide, and the mesopore of spray rail chair communicates with the intake duct of diesel engine respectively, and it is consistent with petrolic injection angle that described nozzle is skewed layout and sprays angle.
Owing to adopt above technological scheme, at the cylinder cap of motor injection apparatus is set, satisfy the gasoline eject request, rationally utilize the original parts of diesel engine, save cost, increase work efficiency.
Description of drawings
Fig. 1 is the structural representation of cylinder cap;
Fig. 2 is the plan view of cylinder cap;
Fig. 3 is the A-A sectional view of Fig. 2;
Fig. 4 is the structural representation of nozzle and spray rail.
Embodiment
As Fig. 1, a kind of gasoline injection system of motor, comprise the cylinder cap 10 that cooperates with diesel motor cylinder, described cylinder cap 10 is provided with spray rail chair 11, connect petrol pump nozzle 21 be fixed on the spray rail chair 11, the quantity of described spray rail chair 11 and number of engine cylinders are coincide, and the mesopore 111 of spray rail chair 11 communicates with the intake duct 12 of diesel engine respectively, and it is consistent with petrolic injection angle that described nozzle 21 is skewed layout and sprays angle.That is to say that a cylinder block correspondence is provided with a spray rail chair 11, correspondence is provided with a nozzle 21 on each spray rail chair 11, and each nozzle 21 all is connected with petrol pump, and petrol pump connects fuel tank, guarantees that gasoline is injected into each cylinder.Petrolic injection angle is to guarantee that motor reaches fuel oil under the optimum state and sprays into the angle that wire track and intake duct axis are, nozzle 21 is spurted into intake duct with gasoline, under the effect of air flue vortical flow, fully mix with inhaled air, form the arms oil gas mixture, realize lighting of gasoline.The present invention reequips diesel engine on the basis of original diesel engine, providing one with the new cylinder cap of the original cylinder body of diesel engine coupling and be installed in nozzle on the cylinder cap, is the equal of that the injection apparatus on the petrol engine is applied on the diesel engine.After cylinder cap is offered spray rail chair 11, set up injection apparatus and just can satisfy petrolic fuel supply requirement, realize that diesel engine makes petrol engine into, rationally utilize the original parts of diesel engine, save cost, this structure is comparatively simple simultaneously, be easy to realize, lowered diesel engine significantly and be transformed into petrolic difficulty, effectively increase work efficiency.
As Fig. 2 and 3, described spray rail chair 11 is for being arranged on diesel engine cylinder cover, boss on 10, offer on this boss for the mesopore 111 that nozzle 21 is installed, the axes intersect in the axis of described mesopore 111 and diesel engine intake road 12 and angle α and the petrolic injection angle of two axial lines are consistent.Nozzle 21 is installed in the mesopore 111, and the axis of its axis and mesopore 111 coincide, and the position of determining mesopore 111 axis has equaled to determine indirectly the angle of inclination of nozzle 21, for nozzle 21 provides good location.
The scope of described angle α is 35 °-65 °, can reach best oil gas admixture when nozzle 21 is in slant range, improves the fuel utilization ratio that gasoline has started.
As shown in Figure 4, the head of described nozzle 21 places in the mesopore 111 of corresponding spray rail chair 11, the head that described nozzle 21 is positioned at mesopore 111 is provided with seal ring 23, the cross section of seal ring 23 is O type structure among the present invention, nozzle 21 is installed in seal ring 23 meeting generation extrusion-deformations in back in the mesopore 111, realize sealing, thereby effectively prevent the gasoline seepage.
Described spray rail chair 11 is tilted-putted quadrangular structure, and seamed edge is parallel with the axis of mesopore 111.The upper-end surface of spray rail chair 11 is square structure, the location when this structure is convenient to nozzle 21 installations.
