Abstract
The utility model relates to a cylinder cover of an engine of a four-cylinder small displacement mini vehicle. Four combustion chambers (2) are abreast arranged on the cylinder cover (1), two inlet valves (3) and two exhaust valves (4) are arranged on each of the combustion chambers (2), two camshaft seat bores (5) with the same structural shape are abreast arranged on the cylinder cover (1), and also two oil channels (6, 7) communicating with the two camshaft seat bores (5) are arranged on the cylinder cover (1). Since the utility model applies a four-valve double camshaft and double oil channel lubricating systematic structure, the power per liter of the engine is increased, the dynamic performance of the engine is notably increased, and thus the engine better adapts to the requirements of rural road conditions and service conditions.
Description
Technical field
The utility model relates to motor, relates in particular to the cylinder cap of the little car engine of the little discharge capacity of four cylinders.
Background technique
At present, discharge capacity disposes the four cylinder engine that cylinder diameter is 65mm, i.e. 465 motors mostly in the minicar below 1 liter.The cylinder cap structure of 465 motors as shown in Figure 1, four firing chambers 2 have been arranged side by side on the cylinder cap 1, on each firing chamber 2 to an intake valve 3 and an exhaust valve 4 should be arranged, be called two air valve structures, camshaft holder hole 5 on the cylinder cap 1 has only one, be referred to as the single camshaft gas distribution structure, what its lubrication system adopted is single oil channel structure, promptly only is provided with an oil duct 6 on cylinder cap 1.The minicar that disposes this motor is used on urban road carrying that the people travels is no problem, but in fact a lot of minicar of China is sold to the rural area, fast development along with agricultural economy, at present the rural market need a large amount of mini vans be used for riding instead of walk, manned, also want double as goods to use simultaneously, because the road conditions in rural area is poor, the existing little car of little discharge capacity generally is short of power, and its performance of operating condition can not satisfy the needs of rural market.
The model utility content
Problem to be solved in the utility model provides a kind of little car engine cylinder cap of the little discharge capacity of four cylinders that helps to improve the power per liter and the power character of motor.
For solving the problems of the technologies described above, the little car engine cylinder cap of the little discharge capacity of four cylinders provided by the utility model, four firing chambers have been arranged side by side on the cylinder cap, each firing chamber all is provided with two intake valves and two exhaust valves, camshaft holder hole on the cylinder cap has two that are arranged side by side, the structure shape in these two camshaft holder holes is identical, also is provided with two oil ducts on the cylinder cap and is connected with above-mentioned two camshaft holder holes respectively.
In the utility model, owing to adopted four valve twin cam shaft structures, can not only improve the power per liter of motor, also make the distribution device of motor be more convenient for disposing, two oil channel structures make the lubricating oil path on the cylinder cap no longer so circuitous, the circulation of lubricant oil is more smooth, and two oil circuits are lubricated two camshafts respectively, have improved the lubrication effect of distribution device.
The beneficial effects of the utility model are: improved the power per liter of motor, engine power performance is able to obvious raising, can adapt to the requirement of rural area road conditions and service condition more.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the existing little car engine cylinder cap of the little discharge capacity of four cylinders.
Fig. 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 2, all be provided with two intake valves 3 and two exhaust valves 4 on four firing chambers 2, each firing chamber 2 being arranged side by side on the cylinder cap 1 of the little car engine of the little discharge capacity of four cylinders (cylinder diameter is 66mm), camshaft holder hole 5 on the cylinder cap 1 has two that are arranged side by side, the structure shape in these two camshaft holder holes 5 is identical, and cylinder cap 1 is provided with two oil ducts 6,7 and is connected with above-mentioned two camshaft holder holes 5 respectively.Owing to adopted four valve twin cam shaft structures, can not only improve the power per liter of motor, also make the distribution device of motor be more convenient for disposing, two oil channel structures make the lubricating oil path on the cylinder cap 1 no longer so circuitous, the circulation of lubricant oil is more smooth, article two, oil circuit is lubricated two camshafts respectively, has improved the lubrication effect of distribution device.
In Fig. 2; in the spark-plug hole 8 of firing chamber 2 spark plug conduit 9 is installed; spark plug conduit 9 is pressed in the spark-plug hole 8 by the drive fit mode during installation; because engine spark plug need often be got dress; utilize spark plug conduit 9 to help to protect the hole wall of spark-plug hole 8; spark plug conduit 9 also has the function of oil removal simultaneously, to prevent that spark plug is by greasy dirt etch on every side.
As can be seen from Figure 2: be used on the cylinder cap 1 bolt hole 10 that links to each other with engine cylinder- body oil duct 6 or 7 and tappet hole 11 between and more close oil duct 5, just outwards move the position of bolt hole 10, reserve more space and process tappet hole 11, to simplify the processing technology in tappet hole 11.
Claims (3)
