What is a crankpin in an engine?
The crankpin is a mechanical part of an engine. Which allows the connecting rod to be attached to the crankshaft very firmly. The surface of the crankpin is cylindrical, to give the rotative force to the large end of the connecting rod. These are also known as connecting rod journals.
What is a crankshaft?
An engine crankshaft is the main revolving component of an engine. It sits within a combustion engine, on top of the engine block, connected to the pistons via connecting rods. The combination of pistons, connecting rods, and crankshaft are what create the ‘crank’ mechanism.
There are two different types: monolithic crankshafts and assembled crankshafts. The former is used in multi-cylinder engines and the latter can be found in motorbike engines. Usually, most crankshafts are made from iron, forged steel, or steel alloys.
What type of engines use crankshafts?
All engines feature a crankshaft including ships, aeroplanes, trains, and cars.
What are the signs that a car’s crankshaft is damaged?
If your vehicle’s crankshaft position sensor is faulty or there are problems with the wiring, the crankshaft signal could cut out, whilst the engine is running resulting in your engine stalling. Wiring problems and faulty crankshaft position sensors are two common issues.
Watch out for the below warning signs:
– Problems when trying to start a vehicle
– Complete engine failure
– The vehicle is stalling and you don’t know why
– The check engine light is illuminated
Connecting rod journals
The connecting rod journals are offset from the axis of rotation, and are attached to the big ends of the pistons’ connecting rods. Confusingly, they are commonly also called crank pins or rod bearing journals . A feed of pressurised oil comes through an angled oil passage drilled from the main journal.
Some connecting rods have an oilway drilled through them to to allow oil to be sprayed onto the cylinder wall. When this is the case, the connecting rod journal bearings will have a groove to allow a feed of oil into the connecting rod.
