Abstract
The utility model particularly relates to a small-sized diesel engine cylinder end, and belongs to the technical field of diesel engines. The cylinder end comprises a cylinder end body and an oil spraying nozzle; a gas inlet path and a gas exhausting path are respectively arranged at two sides of the cylinder end; a venting path for increasing the radiating of the oil spraying nozzle is arranged at the inside of the cylinder end body; the gas inlet path and the gas exhausting path are parallel; an included angle smaller than 90 degrees is formed between the gas inlet path and the venting path. As a radiating piece and the venting path are additionally arranged, the radiating of the whole cylinder end is enhanced, and the radiating of the oil spraying nozzle is also improved due to wind from the venting path, so the seizure probability of oil spraying needle holes due to carbon deposition is greatly reduced when the cylinder end is in normal use.
Description
Technical field
The utility model belongs to Diesel Engine Technique Field, refers in particular to a kind of cylinder head of small diesel engine.
Background technique
Usually, the layout of the intake valve of cylinder head and exhaust valve in small air-cooled diesel engine, be the straight line that is parallel to crankshaft center line along, and the line of centres of intake valve, exhaust valve is parallel with crankshaft center line, and two the projection of line is overlapping, and the cooling duct of setting passes through in the intake valve place.It is the cylinder head entity part that this structure makes between intake valve and exhaust valve, cooling air carries out wind cooling temperature lowering from the entity that cooling duct to intake valve forms the intake valve place, but, be in the condition of high temperature when working due to oil injecting nozzle, oil injecting nozzle can not well dispel the heat, easily cause oil spout pin hole carbon distribution stuck, affect the normal operation of diesel engine.
Summary of the invention
The purpose of this utility model is to provide a kind of cylinder head that strengthens the small diesel engine of oil injecting nozzle heat radiation.
The purpose of this utility model is achieved in that a kind of cylinder head of small diesel engine, comprise cylinder head body, oil injecting nozzle, the cylinder head both sides are respectively arranged with intake duct and air outlet flue, and wherein, described cylinder head body inboard is provided with the ventilation flue for increasing the oil injecting nozzle heat radiation.
, according to a kind of cylinder head of small diesel engine of the above, wherein, be arranged side by side respectively intake valve valve seat and exhaust valve valve seat near air inlet road junction and exhaust road junction on described cylinder head body end face.
According to a kind of cylinder head of small diesel engine of the above, wherein, described ventilation flue is vertical and between intake valve valve seat and exhaust valve valve seat.
According to a kind of cylinder head of small diesel engine of the above, wherein, described intake duct and air outlet flue are parallel to each other, and intake duct and ventilation flue form the angle less than 90 °.
According to a kind of cylinder head of small diesel engine of the above, wherein, described air outlet flue one side has additional a radiating fin.
The utility model outstanding and useful technique effect compared to existing technology is:
1, owing to having increased radiating fin and ventilation flue, the heat radiation of whole cylinder head is improved;
2, the wind from ventilation flue also is improved the heat radiation of oil injecting nozzle, make its during normal use the stuck probability of oil spout pin hole carbon distribution greatly reduce.
