Abstract
The utility model relates to a kind of cylinder head sub-assembly, it comprises cylinder head body (1), described cylinder head body (1) is provided with spiral gas-entered passageway (2) and exhaust passage (3), described gas-entered passageway (2) entrance section is trapezoidal, the diameter of described gas-entered passageway (2) and exhaust passage (3) is 32mm, be provided with choked flow in described gas-entered passageway (2) to take (4), the height that (4) are taken in described choked flow is 11mm.A kind of cylinder head sub-assembly of the utility model, its maximum possible adds air inflow, reduce intake resistance, take by increasing choked flow in gas-entered passageway, make intake swirl stronger, oil inflame is more abundant, substantially increase the combustion performance of diesel engine, decrease the waste of the energy and the discharge of waste gas, its power stability, operational reliability and Security high.
Description
Technical field
The utility model relates to a kind of two cylinder diesel engine, specifically relates to a kind of two cylinder diesel engine cylinder head sub-assembly.
Background technique
Diesel engine be burning diesel oil to obtain exergonic motor, it has a wide range of applications in industrial and agricultural production.Diesel engine is made up of combustion-chamber assembly, power transfer assembly, body and main bearing, distribution device, oil-fired system and speed regulator, lubrication system, cooling system, starting system.Cylinder head is one of strength member of diesel engine, its effect is that sealing cylinder and piston, cylinder sleeve and body form combustion space, the design of cylinder head is directly connected to the power of diesel engine, Economy, functional reliability and servicing ease etc., and the advance of its structure will directly affect fuel consumption rate, NO
xdischarge, reliability of operation and Security etc., therefore appropriate design air cylinder head structure is vital.The deficiency of air of existing factory inside cylinder lid structure, fuel oil can not Thorough combustion, thus causes the waste of the energy, and its power is unstable, affects the raising of diesel engine performance, cannot meet the requirement of higher economical property and more strict emission regulation.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of cylinder head sub-assembly, which increases air inflow, makes fuel oil Thorough combustion, improves combustion performance, power stability, operational reliability and Security good.
The purpose of this utility model is achieved in that a kind of cylinder head sub-assembly, it comprises cylinder head body, described cylinder head body is provided with spiral gas-entered passageway and exhaust passage, described gas-entered passageway entrance section is trapezoidal, the diameter of described gas-entered passageway and exhaust passage is 32mm, be provided with choked flow in described gas-entered passageway to take, the height that described choked flow is taken is 11mm.
Compared with prior art, the utility model has following beneficial effect:
A kind of cylinder head sub-assembly of the utility model, its maximum possible adds air inflow, reduce intake resistance, take by increasing choked flow in gas-entered passageway, make intake swirl stronger, oil inflame is more abundant, substantially increase the combustion performance of diesel engine, decrease the waste of the energy and the discharge of waste gas, its power stability, operational reliability and Security high.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of cylinder head sub-assembly of the utility model.
Wherein:
Cylinder head body 1
Gas-entered passageway 2
Exhaust passage 3
Choked flow takes 4.
Embodiment
