Volume 20ml to 300ml cooling water cavity, the cooling water cavity is not more than 1cm cooling water channel compared to more existing aperture, cold
But cooling-down effect is more notable.A water inlet is provided only with the closing lid face of cylinder head to be used for and the water cooling chamber in cylinder block
Connection, eliminate the bore edges of other water channels that cylinder block water cooling chamber connects with cylinder head water cooling chamber and the inlet opening away from
The distance of edge of combustion chamber is more than 1.5cm, it is ensured that have enough distances, sealing effectiveness between inlet opening and cylinder head combustion chamber
Strengthen, and the area that water channel is contacted with sealing gasket diminishes, the reduction of seal failure risk.Simultaneously because eliminating on closing lid face
Other water channels set, also enhance the rigidity in cylinder head closing lid face, when reducing assembling, work when cylinder block and cylinder head
Deformation of joint surface, further ensures the sealing between cylinder block, cylinder liner, cylinder head.
Because cylinder casing is only connected by a water inlet with cylinder block water cooling chamber, other connection water are eliminated
Road, cooling water reduces with sealing surface contact area, so that cooling water is reduced to the cooling-down effect of cylinder casing near sealing surface.
And closing lid face reduces hole, and nearby heat is more rapidly transferred to cylinder head capsule by cylinder casing in cylinder block closing lid face
External wall, by setting fin, auxiliary heat dissipation on cylinder head outer wall, and can lower cooling system power consumption, improve interior
Combustion engine efficiency.
The multiple fin is horizontally arranged in cylinder head outer wall from top to bottom, can simplify manufacturing process, when air-flow from
When being flowed after forward direction, it ensure that fin flattens out row with airflow direction again, it is ensured that air-flow can take away more heats.
The inlet opening for crossing water water channel is arranged on to the closing lid face corner of cylinder casing, is not increasing cylinder head wall thickness
In the case of, delivery port can be made as far as possible away from cylinder holes, moreover it is possible to make the water cooling passageway on cylinder head not influence cylinder head to enter
The arrangement of gas port position.
The upper top surface of cooling water cavity sets technique through hole, and technique through hole can be blocked with plug, is produced during for excluding processing
Impurity can also as later stage upper surface delivery port.
Using above-mentioned utility model, the sealing gasket between existing water-cooled cylinder body and cylinder head can be avoided to be easily damaged
Cause cooling water to enter in combustion chamber, trigger engine scuffing, embrace cylinder and cylinder head cool effect it is poor the problems such as under
Face combines the drawings and specific embodiments, and the utility model is described in further detail.
