Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
The utility model provides a kind of heavy-duty engine, referring to figs. 1 through Fig. 4, the heavy-duty engine that the utility model provides comprises cylinder cap and has the cylinder body 10 of multiple cylinder barrel, with reference to Fig. 2, the multiple intake ducts 24 be communicated with each cylinder barrel are respectively formed in cylinder cap, and between intake duct 24 and cylinder barrel, be provided with intake valve 25, the air inlet of motor is controlled by time opening or closedown intake valve 25.In addition, heavy-duty engine also comprises the air inlet cavity 22 be arranged on cylinder cap, and this air inlet cavity 22 is communicated with multiple intake duct 24 simultaneously.Gas enters air inlet cavity 22 from heavy-duty engine outside, then participates in burning in the cylinder barrel being entered cylinder body 10 by intake duct 24.It should be noted that, the shape, size etc. of air inlet cavity 22 carry out designing according to actual needs, as long as the parameters such as the swirl rate of gas, the pressure loss can be made to meet the requirements, thus can make cylinder interior air inlet fully.
The cylinder cap of heavy-duty engine of the present utility model is compared with existing cylinder cap, owing to being provided with air inlet cavity 22 on cylinder cap, thus the weight of cylinder cap correspondingly reduces, and air inlet cavity 22 instead of existing intake manifold, thus decrease the weight and volume shared by component such as intake manifold, pad and bolt, in addition, again because improve the efficiency of assembling of heavy-duty engine without the need to installing intake manifold.
In addition, each cylinder barrel on cylinder body 10 can be communicated with two intake ducts 24, and gas (fresh air or flammable mixed gas) is sucked in cylinder body more, thus ensures that heavy-duty engine air inlet is abundant, when air inlet is abundant, heavy-duty engine sends larger power.But the utility model does not limit the number of the intake duct 24 be communicated with each cylinder barrel, can design according to specific needs.
With intake duct 24 accordingly, with reference to Fig. 2, the heavy-duty engine that the utility model provides also comprises the multiple air outlet flues 27 be communicated with multiple cylinder barrel, and air outlet flue 27 is also arranged in cylinder cap.The coconnected air outlet flue more than 27 with each cylinder barrel in theory, the exhaust efficiency of heavy-duty engine is higher, but also have that oil consumption increases thereupon, the manufacturing process of cylinder cap becomes the shortcoming such as complicated relatively, therefore, the preferred set-up mode of the utility model is that each cylinder barrel is communicated with an air outlet flue 27, and an air outlet flue 27 can meet the exhaust requirements of heavy-duty engine.
In addition, the loss of weight to heavy-duty engine is realized by the weight reducing heavy-duty engine cylinder body, with reference to Fig. 4, the utility model is under guarantee heavy-duty engine cylinder body bears the prerequisite of high detonation pressure state, preferably, the wall thickness in the non-bearing region of heavy-duty engine cylinder body is designed to 3.7-5.3mm, and this is much less than the thickness range 4.5-6.5mm of existing heavy-duty engine cylinder body, thus greatly can reduce the own wt of heavy-duty engine cylinder body.
Particularly, non-bearing region can be skirt section or oil return cavity, and the thickness of skirt section or oil return cavity can be designed as 3.7-5.3mm.
Finite element analysis (FEA can be passed through in above-mentioned non-bearing region, FiniteElementAnalysis) computational methods etc. calculate, the wall thickness in non-bearing region is designed to thin relative to the wall thickness in non-bearing region of the prior art, finally reaches the object of the weight reducing heavy-duty engine.
