Bent connecting rod after Hydrolock Same connecting rod, turned 90°. Hydrolock (a shorthand notation for hydrostatic lock or hydraulic lock) is an abnormal condition of any device which is designed to compress a gas by mechanically restraining it; most commonly the reciprocating internal combustion engine, the case this article refers to unless otherwise noted.
The agency says in documents posted on its website Monday that connecting rod bearings on vehicles with 3.5-liter V6 engines can fail, leading to complete engine failure. Connecting rods link the ...
The National Highway Traffic Safety Administration's probe affects the 2016–2020 Acura MDX, 2018–2020 Acura TLX, 2016–2020 Honda Pilot, 2017–2019 Honda Ridgeline and 2018–2020 Honda Odyssey.
A connecting rod, also called a 'con rod', [1] [2] [3] is the part of a piston engine which connects the piston to the crankshaft. Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. [4] The connecting rod is required to transmit the compressive and tensile forces from ...
Excess bearing clearance increases the pressure loss between the first and last bearing in a series. Depending on condition, an engine may have acceptable gauge pressure, and still only 5 psi pressure at one connecting rod, which will fail under high load. The pressure is actually created by the resistance to the flow of the oil around the ...
The crankpin connects to the larger end of the connecting rod for each cylinder. This end of the connecting rod is called the "big end", as opposed to the "small end" or "little end" (which connects to the wrist/gudgeon pin in the piston). The bearing which allows the crankpin to rotate around its shaft is called the "rod bearing". [5]
It is also a significant cause of failure in components subjected to rolling or rolling/sliding contacts, such as rolling-contact bearings, gears, and cam/tappet arrangements. [5] The alternating stress field in RCF can lead to material removal, varying from micro- and macro- pitting in conventional bearing steels to delamination in hybrid ...
Gudgeon pin connection at connecting rod. Gudgeon pin fits into gudgeons inside piston.. In internal combustion engines, the gudgeon pin (English, wrist pin or piston pin US English) connects the piston to the connecting rod, and provides a bearing for the connecting rod to pivot upon as the piston moves.
