The ellipse shape is called a "cam grind." Normally the cam grind on a piston is between 0.020 to 0.045 inch. That isn't much, but it is critical because piston dimensions change as it reaches operating temperature. A number of pistons also incorporate a "barrel grind" or finish. This means the skirt bulges outward below the oil ring ...Web

Crankshaft. The combustion of fuel shoots the piston straight down the cylinder, it's the job of the crankshaft to convert this linear motion into rotation - basically by swinging around and pushing the piston back up the cylinder. The terminology of a crankshaft is quite specialist, so we'll start with naming a few parts.Web

This Mahle piston illustration reveals how a 1.0mm-1.0 mm-2.0 mm ring package tightens the ring stack enough to position the oil ring land above the wrist pin. This helps with ring durability and improved oil control. These pistons also would not need the oil support rail commonly used on pistons where the wrist pin bisects the oil ring land.Web

Grinding/squeaking when braking. A stuck piston can make all kinds of sounds, some of which can be described as "squeaking" or "grinding." Other sounds that might occur can be loud thuds or clunks. Sometimes these sounds are from worn brake pads or rotors, but can also be due to a stuck piston. Reduction in braking abilityWeb

As with a crankshaft though, the forging process gives us a part that is much denser with greater ductility than a cast piece. All cast pistons contain a certain amount of silicon, generally 10-12 percent, the amount of which is known as the "eutectic point.". Changes to the aluminum alloy can, however, produce stronger cast parts better ...Web
