The skirt portion of the VAS 5054A piston means of the lower portion

The skirt portion of the VAS 5054A piston means of the lower portion of the piston, its role is to keep the piston in the reciprocating movement of the vertical posture, that is, the guide portion of the piston. The shape of the piston skirt is very particular about especially like cars light passenger cars, the designers from the structure and performance of the engine, the often brains piston skirt, compact and smooth operation to try to make the engine structure.

The piston pin is a piston connected via a piston pin and connecting rod supporting portion, located above the portion of the piston skirt. Is unique in that a high-speed engine piston pin pin housing bore and the piston is not necessarily in the same centerline plane can be offset to one side a little bit, namely the work of stroke piston contact with the side of the offset of the cylinder wall, so after the piston to the upper dead point transform direction the piston percussion Gangbi degree VAS 5054A  reduced, thereby reducing the engine noise.

The automotive big to have tens of thousands of parts, such as the crankshaft, gearbox, small spring washers, bolts, nuts. Each part has its role, such as piston rings "Little Dot", from the shape appears to be simple, very light weight, the price is very cheap, but the role was no small matter. Lack of it of course, the car could not move, even if it just a little small problems, the car will not normal, either fuel or underpowered. Whole piston group with cylinder and piston group real contact with the cylinder the cylinder wall, piston rings, it fills the gap of the piston and the cylinder walls, closed NEXIQ 125032 combustion chamber, so it is the engine most likely to wear parts .
