Abstract
The utility model relates to a cylinder head for single-cylinder horizontal wind-cooling diesel engines with 100 millimetric cylinder diameter, which is improved on the basis of original cylinders. An oil atomizer fixed hole (1) is arranged on the windward lateral surface of the cylinder head, and an vent outlet (2) is arranged on the relative other lateral surface of the cylinder head, an air inlet (3) is disposed on the upper lateral surface of the cylinder head. When in work, an oil atomizer installed on the oil atomizer fixed hole (1) is cooled by cold air, therefore the utility model has the advantages that the cooling effect to the oil atomizer is favorable, the needle valve of the oil atomizer is prevented from deadlocking owning to overheating, the early start performance of diesel engines is improved, and the discharge of black gas is reduced and the like.
Description
One, technical control territory
The utility model is a kind of cylinder head that cylinder diameter is 100 millimeters a single-cylinder horizontal air-cooled diesel engine that is used for.
Two, background technique
The cylinder head of common single-cylinder air-cooled horizontal cylinder diesel engine, its mounting hole of oil sprayer is on the top of cylinder head, during use, oil sprayer is positioned at the crosswind face that cooling air flows to, cooling effect is poor, causes oil-fuel injector needle-valve stuck because of overheated sintering easily, causes faults such as diesel engine starting difficulty, over-emitting black exhaust.
Three, summary of the invention
For overcoming above-mentioned shortcoming, the purpose of this utility model is can make the oil sprayer good cooling results for 100 millimeters single cylinder minister formula air-cooled diesel engine provides a kind of, prevent the overheated single-cylinder air-cooled diesel engine cylinder head that the sintering stuck phenomenon occurs of oil-fuel injector needle-valve for cylinder diameter, so that improve the diesel engine starting performance, reduce the over-emitting black exhaust phenomenon.
To be the purpose that reaches above-mentioned be located at the side that facings the wind of cylinder head with mounting hole of oil sprayer to the utility model, and relief opening is located at relative another side, and suction port is located at the upper side of cylinder head, and intake duct is a spiral inlet duct.Oil sprayer is located in the windward side that cooling air flows to like this, substantially improved the cooling effect of oil sprayer, make oil-fuel injector needle-valve can be not poor because of cooling effect, to cross thermal sintering stuck, thereby reduced single-cylinder horizontal air-cooled diesel engine starting difficulty, faults such as over-emitting black exhaust have improved the functional reliability of single-cylinder horizontal air-cooled diesel engine.
Four, description of drawings
Fig. 1 is the utility model schematic representation;
Fig. 2 is the plan view of Fig. 1.
Five, mode of execution
As shown in drawings, mounting hole of oil sprayer of the present utility model (1) is located at the side that facings the wind of cylinder head, and relief opening (2) is located on the relative another side, and suction port (3) is located at the upper side of cylinder head, and intake duct is a spiral inlet duct.Oil sprayer is installed on the mounting hole of oil sprayer (1), its concrete structure and size:
Mounting hole of oil sprayer (1) is 21～25 ° with bottom surface angle α, and mounting hole of oil sprayer (1) is to the centre distance A of cylinder of diesel engine
1Be 5～9 millimeters, A
2It is 9～11 millimeters;
Relief opening (2) is that 23～27 millimeters, longitudinal pitch E are 13～16 millimeters to the transverse pitch D of cylinder of diesel engine.
Suction port (3) is that 9～12 millimeters, longitudinal pitch C are 23～27 millimeters to the transverse pitch B of cylinder of diesel engine.
During the utility model work, the guide housing of cooling air on diesel engine blows to the utility model, at first oil sprayer cooled off, again to other position cooling of the utility model, discharge through relief opening then, the outlet pipe on the diesel engine that is installed in the utility model relief opening (2) is cooled off.The required fresh air of diesel combustion then by suction port (3) after intake duct forms intake swirl, enter in the cylinder of diesel engine.
Because on the side that facings the wind of cylinder head, cooling-air is at first right with mounting hole of oil sprayer (1) design for the utility model Fuel injector cools off, and has avoided the overheated of fuel injector. Therefore, the utlity model has and can make the fuel injector good cooling results, It is stuck to prevent effectively that oil-fuel injector needle-valve from crossing thermal sintering, improve diesel engine early moving performance, reduce the spies such as generation of over-emitting black exhaust The point.
Claims (4)
1, a kind of single-cylinder horizontal air-cooled diesel engine cylinder head, it is characterized in that mounting hole of oil sprayer (1) is located on the side that facings the wind of cylinder head, relief opening (2) is located on the relative another side, and suction port (3) is located on the upper side of cylinder head, and intake duct is a spiral inlet duct.
