Summary of the invention
The technical problems to be solved in the utility model is, in order to remedy the deficiency of existing cylinder block, and provide a kind of ventilate unimpeded, lubricating oil return road rationally, the engine cylinder body of compact structure.
The utility model is to solve the problems of the technologies described above to adopt following technological scheme: a kind of engine cylinder body, include one group of cylinder and around the water jacket of cylinder, the cylinder block end face connects cylinder head, and the bottom is a crankcase chamber; It is characterized in that: the vent hole that up/down perforation also is set on cylinder block air inlet side.
For making the machine oil above the cylinder cap get back to oil sump, the spill port of up/down perforation is set also on cylinder block.
For the pressure balance of crankcase chamber inside, described crankcase bearing seat centre also is provided with vent hole, bearing support seat side yet is provided with vent hole.
Be to shorten the motor total length, describedly at the cylinder block front end oil pump is set deep gouge is installed.
Good effect of the present utility model is, by with back oil road and vent design on cylinder body, and deep gouge is installed in cylinder body Front-end Design oil pump, make oil pump can be directly installed on cylinder interior, thereby reach compact structure, cooling water flow tissue is rationally; Fluting and punching make between adjacent each cylinder to be communicated with on the cylinder block-crankcase main bearing seat, can make when motor inclination several angle the crankcase inner ventilation smooth and easy like this.
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Description of drawings
