Deng), and former piston cooling nozzle oil leab 13 is entered by crankcase front end (i.e. X-direction) former oblique oil duct 12, it is piston
Machine oil needed for cooling offer, while there is one lubricating oil to be shunted by former oblique oil duct 12, pass through the vertical oil cylinder head way 14 in former front end
Into cylinder cap system (referring to Fig. 2).But cast analysis is shown, in the former OCV Oil Control Valve mounting platform 15 of former OCV Oil Control Valve 16
Place is (referring to Fig. 3).Due to the excessive generation thermal center of wall thickness, there is blow hole and rarefaction defect in inside；Due to the position that stomata is loose
Setting between oilhole and bolt hole, running through for stomata can cause oil leakage fault.In addition former main oil gallery 11 is connected to live with original
The horizontal tiltedly oil duct 12 in former front end for filling in the front end of cooling nozzles oil leab 13 is inclination oil duct, it is impossible to precasting, can only pass through machine
Add, but machine adds the manufacturability of oblique oil duct poor, there are requirements at the higher level to equipment cutter etc., machine add aluminium skimmings, burr cleaning remove compared with
Difficulty, so as to cause cylinder body machine to add rear product qualification rate low.Therefore, there are further improved need in the former scheme of crankcase oil circuit
Ask.
