What are the two types of gudgeon pin?
Gudgeon pins use two broad design configurations: semi-floating and fully floating.
What are the three types of piston pins?
There are three methods of attaching a piston to a connecting rod: Shown from left to right are three popular styles of wrist-pin locks: snap ring, wire clip and Spirolocks. Anchored or fixed pin—The wrist pin pivots freely within the little end of the connecting rod, usually with the help of a bushing.
Which are the two types of Bendix drives?
Explanation: Inboard and outboard are the two types of Bendix drives. In the outboard type pinion moves away from the starting motor to engage the flywheel whereas in the inboard type it moves towards the starting motor.
What kind of pin is a gudgeon pin made of?
The gudgeon pin is known as a forged short hollow rod which is mostly made of a steel alloy having high strength and hardness which might be separated physically from both the connecting rod and piston or crosshead. In the case of small or high-revving automotive engines design of the gudgeon pin is quite challenging.
How is the gudgeon pin used in an internal combustion engine?
In internal combustion engines, the gudgeon pin (UK, wrist pin US) connects the piston to the connecting rod and provides a bearing for the connecting rod to pivot upon as the piston moves.
What are the working conditions of a gudgeon pin?
The gudgeon pin operates under the highest temperatures which is experienced inside the engine with most of the difficulties in the lubrication due to its position whereas the small and light remains fit inside the diameter of the piston and does not unduly add to the reciprocating mass.
How is a gudgeon pin clamped to a piston?
The gudgeon-pin is clamped to one of the piston bosses wherein the small-end of the connecting-rod is lined up with an interference-fit phosphor-bronze plain bush bearing. This bush helps in locating the gudgeon-pin and thus provide it a low-friction surface.
