Embodiment Construction

[0016] See Figure 1 to Figure 4 , The cylinder head 12 of this embodiment adopts an upper camshaft type. One end of the cylinder head 12 is provided with a sprocket chamber 20, and the other end is provided with a spark plug hole 15'. The upper part of the cylinder head is provided with a cavity 7 for installing a valve lifting device. A cam chamber 10 is provided between the cavity 7 and the valve holes 6 of the intake and exhaust passages. The two ends of the cam chamber are provided with One of the holes 9 supporting the camshaft communicates with the sprocket chamber 20; the cavity 7 communicates with the cam chamber 10 through the lower guide hole 17, and the upper end of the cylinder head 12 is provided with an upper guide hole 19 corresponding to the lower guide hole. The guide hole 19 is covered with a cover plate 8; the walls on both sides of the cavity 7 are provided with valve adjusting holes 18 and covered with a cover 11. The cylinder head 12 and the cylinder block 14...

Abstract

The invention relates to a cylinder of motorcycle engine, which comprises a cylinder cover and a cylinder body connected via bolt, wherein the cylinder cover and cylinder body are combined on the inlet and outlet channels; the combine surface of cylinder cover is arranged with grooves for forming inlet and outlet channels; said grooves are arranged with valve hole for mounting valve tube; the combine surface of cylinder body is arranged with grooves relative to the grooves of the combine surface of cylinder cover to form inlet and outlet channels; said grooves are through to the inlet and outlet of burning room; the burning room is at the upper part of cylinder hole of cylinder body; the burning room has spark plug hole; the cylinder cover is combined with burning room, and the grooves of cylinder cover and the grooves of cylinder body will form inlet and outlet channels. The invention can change the position of combine surface between cylinder cover and cylinder body, to confirm the sealing property of burning room, to improve the gas charge efficiency of engine and improve the inlet and outlet amounts of engine.

Description

Technical field [0001] The invention belongs to the field of cylinders of combustion engines, and particularly relates to a cylinder of a motorcycle engine. Background technique [0002] At present, the cylinders of motorcycle engines are roughly divided into two categories: One type of cylinder head and cylinder block are separated and fastened together by bolts. Since the cylinder head and the cylinder body are separately processed, this type of cylinder is easy to process and easy to assemble. Therefore, the current motorcycles mostly use this type of cylinder. However, this type of cylinder is generally provided with a combustion chamber on the joint surface of the cylinder head and the cylinder block, and the intake and exhaust passages are arranged on the cylinder head to communicate with the combustion chamber, or on the cylinder block to communicate with the cylinder bore. Because the combustion chamber is located on the joint surface, and the area of ​​the joint surface ...
