A compressor that has a piston that travels back and forth in a cylinder is a?

It is simply a piston compressor.


Why are connecting rods used in a car engine?

Con rods are used not ony in car engines, but in just about all piston engines. They're needed to turn the reciprocating(back-forth) motion of the piston into the rotary motion of the crankshaft. That rotation is then - via the gearbox, prop shaft etc what propels the car forward.


What is bump clearance?

It is the space between the top of the piston and the bottom of the cylinder head. Great care should be used when putting an engine back together to make sure the bump clearance is not 0 so that the piston will not hit the head cylinder.


What is function of piston pin of a piston?

The piston pin joins the piston to the connecting rod. Igniting fuel / air mixture pushes down on the top of the piston, the piston transfers the force to the connecting rod, which in turn pushes against the crankshaft, converting the up and down motion of the piston to the rotary motion of the crankshaft. The piston pin allows back and forth motion of the connecting rod (as it's other end is moving back and forth in a circular motion with the crankshaft.)...if instead of a pin a solid joint was made from the piston to the connecting rod the engine would not be able to run, as the connecting rod would try to rock the piston back and forth (side to side, not up and down) as the rod was moved sideways with the crankshaft.


How do car engines operate?

car engines work on a simple basis of suck, squeeze bang, blow. this means that in the first stroke of a piston the air fuel mixture is sucked into the cylinder, the valves then close. when the piston travels back up the cylinder it compresses the air fuel mix and then the spark plug ignites this making the explosion and forcing the piston back down the cylinder, this is the bang stage. then finally the piston travels back up the cylinder and blows out all the exhaust gases. this completes the four stroke cycle for the engine.


Differentiate between a reciprocating mortion of a cylinder piston and a rotary motion?

Rotary means going around, like in a Wankel. Reciprocating means going back and forth. like in a ordinary piston engine.


How do you get panties that fak you these would have 1 or 2 dildos inside that would piston back and forth out of you while you were them?

Ask in an adult sex shop for advice on this.


How is a diesel engine different from other internal combustion engines?

Its a compression engine, as opposed to a spark driven combustion. No spark plugs! To start the engine, the piston is forced up (by a starter), it compresses the (heated) fuel in the piston which then ignites (under pressure) forcing the piston back down and initiating the engine to turn over.


What is the speed of an steam engine?

It is the number of strokes (forward and back) the piston makes in one minute. For radial (turbine) and rotary steam engines, it is the number of revolutions per minute.


How does an automobile's power plant works?

I cant really understand exactly what you are saying but if you are talking about the motor it varies upon what car you have, but most engines are piston engines that have a piston on top of a rod that is on top of a crankshaft, that moves when the engine is at work, there are 2 valves per cylinder which open at certain times of the engine cycle, it starts when the intake valve opens allowing gas and air mixture to come in when the piston is pulling down it pulls the mixture in, the piston moves back up and causes compression which at the perfect timing the spark plug fires and causes a explosion in the cylinder pushing the piston back down, the exhaust valve opens and the piston moves back up pushing all the exhaust gasses out and restarting the cycle but remember there are more than one piston in a typical car engine so there are many pistons doing a cycle at different intervals keeping the engine running.


What causes back pressure?

Usually back pressure is caused by worn piston rings, combustion gasses passing the rings into the sump, there are also some engines which have positive oil pan ventilation trough the air filter with a suction pipe (BMW engines)Back pessure goes hand in hand with light blue smoke and lack of compression.


Is gas turbine an ic engine?

Gas turbines are a type of Internal Combustion engine, however; Assuming that you want to know the difference between a recpirocating piston engine and a gas turbine engine, the simple answer is that ICE's (Internal combustion engines) create work by moving a crank that is connected to a piston. An explosion in the piston chamber pushes a piston (or series of pistons) attached to a crankshaft, which turns the shaft. The gas turbine works by turning a shaft connected to a turbine. The turbine is powered by a compressed feul-air mixture. A stream of gas is compressed with air and forced through a chamber containing the turbine. The turbine turns the shaft as a result of complex mechanics that control the movement and flow of the compressed fuel-air mixture. The basic mechanical difference: A reciprocating piston engine uses a linear "back and forth" motion to turn a shaft, and the gas turbine engines relies on a constant circular motion to turn a shaft.
