Specific implementation mode
Specific embodiment of the present utility model is made into one by the description to optimum embodiment below against attached drawing
Step detailed description.
The utility model specific embodiment is：As shown in Figure 1 and Figure 2, a kind of engine link, including gonnecting rod body 1,
Big end 2 and small end of connecting rod 3 is respectively set in 1 both ends of gonnecting rod body, and the piston pin hole being connect with piston is arranged on big end 2
21, the crankshaft hole 31 being connect with bent axle is arranged in small end of connecting rod 3, and oil storage tank 32, oil storage tank 32 and piston are provided on small end of connecting rod 3
Pin hole 21 is connected with crankshaft hole 31.
Fuel injection passage 5 is provided with and communicated between oil storage tank 32 and crankshaft hole 31, fuel injection passage 5 is set as tapered channel, spray
Oily channel 5 is more than close to the aperture of one end of big end 2 close to the aperture of 3 one end of small end of connecting rod, improves the stream of lubricating oil
