Abstract
The utility model relates to a novel water jacket structure of a gas cylinder cover for an engine. The gas cylinder cover assembly is internally provided with a burning room; the inner wall of the gas cylinder assembly is respectively provided with a straight passageway and an inclined passageway above the burning room; the direction of the straight passageway is horizontal and is positioned above the inclined passageway; and the direction of the inclined passageway is oblique and downward. By increasing a cooling water passageway near to an exhausting side, the novel water jacket structure leads the burning room to have two cooling passageways and guarantees that the burning room is adequately cooled, thereby being capable of leading the burning room to obtain the ideal cooling effect.
Description
Technical field
The utility model relates to a kind of jacket structure for water, especially relates to a kind of new work engine cylinder head jacket structure.
Background technique
At present, it is coolant exhaust road and firing chamber that existing engine cylinder cap cooling jacket mainly acts on, but because the compact structure of small displacement engine, effect is undesirable when the cooling combustion chamber, and is overheated easily.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, a kind of compact structure, reasonable in design is provided, increasing cooling water channel, make the firing chamber that two cooling channels be arranged, thereby guarantee the new work engine cylinder head jacket structure that fully cool off the firing chamber near exhaust side.
In order to achieve the above object, the technical solution adopted in the utility model is: have the firing chamber in the cylinder cover complement, on the inwall of cylinder cover complement, the top that is positioned at the firing chamber has straight passage and access ramp, straight passage direction level and be positioned at the top of access ramp, the access ramp direction is tilted to down.
The utility model has the advantages that:
Because the utility model makes the firing chamber that two cooling channels be arranged increasing cooling water channel near exhaust side, guaranteed that the firing chamber fully cools off, thereby can make the firing chamber obtain desirable cooling effect.
Description of drawings
Fig. 1 is the utility model structural representation;
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, have firing chamber 3 in the utility model cylinder cover complement 4, on the inwall of cylinder cover complement 4, the top that is positioned at firing chamber 3 has straight passage 1 and access ramp 2, straight passage 1 direction level and be positioned at the top of access ramp 2, access ramp 2 directions are tilted to down.
The utility model cooling liquid when arranging firing chamber 3 cooling jackets near exhaust side is cooled off firing chamber 3 by two passages, cool off 3 tops, 1 pair of firing chamber of straight passage, 2 pairs of firing chamber 3 inwalls of access ramp cool off, thereby make head combustion chamber 3 cool off more fully.
Claims (1)
1. new work engine cylinder head jacket structure, comprise straight passage (1), access ramp (2), firing chamber (3) and cylinder cover complement (4), it is characterized in that: have firing chamber (3) in the cylinder cover complement (4), on the inwall of cylinder cover complement (4), the top that is positioned at firing chamber (3) has straight passage (1) and access ramp (2), straight passage (1) direction level and be positioned at the top of access ramp (2), access ramp (2) direction is tilted to down.
