Technically both, before the vehicle is running on its own via combustion the crankshaft rotates and moves the pistons, once combustion has occurred the pistons take over if you will and turn the crank which rotates the next piston into position for combustion

How does the egine make the car move?

The engine has a crankshaft that is connected to all the pistons in the engine. When the engine is running the pistons are moving up and down and are turning this crankshaft. The crankshaft in turn is spinning a shaft connected to the transmission. The transmission is turning a driveshaft that is connected to the differential which in turn is turning an axle connected to the wheels.


Where is the crankshaft on a 1997 Jeep Cherokee?

Generally speaking the crankshaft is located deep within the engine. The pistons are connected to the crankshaft and it is the device that turns the up and down motion of the pistons into a horizontal motion that drives the transmission and in turn the drive shafts that turn the wheels. If you ever have an opportunity to see your crankshaft that means your engine has been torn completely apart for a major overhaul.


What is the basic motion of the car?

The basic motion of a car is linear motion produced by the crankshaft, which is achieved by vertical motion of the pistons in the cylinders to turn and produce linear motion of the crankshaft.


What is the function of the crankshaft?

Is the crankshaft a internal combustion engin?

The crankshaft is part of a piston engine, which can be either an internal combustion engine (one that runs on gasoline, diesel, propane, natural gas or carbon monoxide) or an external combustion engine (a steam engine). The pistons are connected to the crankshaft through connecting rods. The pistons turn the crankshaft, which creates the rotating motion you bought the engine for.


Does the crankshaft move the pistons up and down?

the pistons drive the crankshaft via the connecting rods, though on start up the starter motor drives the crankshaft in its proper rotation direction to get the ball rolling


What is the force that keeps the crankshaft turning?

The crankshaft has counterweights which are placed in such a way as to provide momentum when the the power stroke of any piston is absent. This drives the crankshaft to spin until the next power stroke of a piston drives it further.


Can a diesel crankshaft and pistons work in a gas engine?

No.


What is the purpose of the crank shaft?

The crankshaft is an internal component of the engine that converts an up and down movement of the pistons to a rotational movement of the the crankshaft. This is provided to the powertrain for movement. The bottom of the pistons are attached to the crankshaft with main bearings.
