What Is A Strutted Piston? - Wiseco

Box strutted pistons work well in certain high-stress situations, but not so well in others. "It could be a high-revving application where you don't want to carry a 2.750 pin. But you could carry a 2.250 pin. Again, you can design the piston to simulate a longer wrist pin and give you more integrity on the pin axis," says D'Agostino.

General Information for 60 Series Detroit Diesel Engines ...

Piston Pins: Third generation engines have two different weight piston pins (heavy and light). Both piston pins are the same OD but differing ID bores. The heavy pin has a 0.86" inside bore and the light pin has a 1.02" inside bore. It seems that updating to the heavy piston pin is preferred, BUT this must be done in complete sets only.

Gudgeon pin - Wikipedia

The gudgeon pin is typically a forged short hollow rod made of a steel alloy of high strength and hardness that may be physically separated from both the connecting rod and piston or crosshead. The design of the gudgeon pin, especially in the case of small, high-revving automotive engines is challenging.

Wrist Pin Locks: Different Styles and How To Install Them

Anchored or fixed pin—The wrist pin pivots freely within the little end of the connecting rod, usually with the help of a bushing.The piston is locked to the pin using screws that go through the pin bosses into the pin. This method is used mostly in industrial engines and never seen in the performance market, unless perhaps a rare vintage application.

Automotive Mechanics: Piston designs

 · Petrol engines use a slipper-type piston (Figure 6.10). Cutting away the skirt of the piston not only reduces the mass of the piston, but also provides clearance for the crankshaft balance weights when the piston is at BDC. This enables shorter connecting rods to be used, permitting a more compact engine design.

The name 'trunk piston' derives from the 'trunk engine', an early design of marine steam engine. To make these more compact, they avoided the steam engine's usual piston rod with separate crosshead and were instead the first engine design to place the gudgeon pin directly within the piston. Otherwise these trunk engine pistons bore little ...
