This video explains about the diesel engine piston and crank shaft.
Points to be noted:Mechanical Engineering tutorials videos
Piston skirt: It is the side wall of the piston as show in the video, this portion will be encaging with the cylinder walls.Engineering tutorials
1st compression ring: The purpose of this ring is to prevent compression leak. This ring is connected close to the piston top.
2nd compression ring: The purpose of this ring is also to prevent compression leak. This ring is fixed beneath the 1st compression ring.

2nd compression ring: The purpose of this ring is also to prevent compression leak. This ring is fixed beneath the 1st compression ring.
Oil ring: The oil ring is fixed beneath the 2nd compression ring. The function of this ring Hydraulic tutorialsensures effective cooling and lubrication of piston and preventing the engine oil from getting in contact with the heat produced due to compression and power.
Gudgeon pin: This pin is used to fix the crank shaft small end with the piston.
Circlip: This clip is used to lock the gudgeon pin with the piston.
Connecting rod: This unit is used to connect the piston with the crankshaft. Fracture split connecting rod is used in this engine to ensure proper mounting of the crank shaft big end.
Connecting rod small end: This end is fixed with the piston using gudgeon pin.
