A crankshaft is the component of an engine that consists of a rotating shaft, which is used to convert the reciprocating motion of pistons into rotational motion. Crankshafts are most commonly found in internal combustion engines and include four different parts: main journals, crankpins, crank webs and counterweights. If you want to know โhow crankshaft worksโ here we give some simple answers.
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.
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.
- Problems when trying to start a vehicle
- Complete engine failure
- The vehicle is stalling and you donโt know why
- The check engine light is illuminated
Grinding, machining, heat treatment and straightening of crankshafts and main bearing journals are all common services that need to be carried out in both private and commercial vehicles. For example, a bent crankshaft in a ferry is a common cause of engine failure. Take a look at how we dealt with this emergency when a ferry's crankshaft became bent [https://www.in-situmachiningsolutions.com/project/in-situ-machining-solutions-respond-quickly-to-major-crankshaft-failure-on-a-ferry/].
