One believes you are talking about piston engines- such as a V-l2 or Flat-6 as opposed to Jet or turbine engines. almost all automobiles with the exception of the Rotary-engined Mazda, use piston internal-combustion engines. With aircraft there are piston engined, Turbo-Prop, and straight turbine or turbo-jets. Rockets are a bit out of the pale for common use.
all car engines are internal combustion most car engines are Reciprocating piston some mazdas use wankel rotary engines hybrids use reciprocating piston engines in combination with electric motors
The central part of the top of a piston, often raised in some engines.
Airbus aircraft all have jets, not piston engines.
An aircraft propelled by jet engines rather than piston engines.
piston engines have more torque than jet engines..
jet engines, turbojet engines, turbo-prop engines, four-stroke piston driven engines... Can you be more specific?
All vehicles with piston engines.
Diameter of the piston head.
This is a device that is commonly used on very large displacement engines and large steam engines. The crankshaft connecting rod is attached at the slider end to a piston shaped object. This object is the attached bay another beam or rod to the piston the does the work. In a steam engine this allows the upper connecting rod to be sealed so the piston can make power going in both directions. If you look at video of steam trains you can see this in action In large diesel engines it reduces wear on and failures of the piston.
Piston engines vary from little 1 cylinder engines that power a weed trimmer or leaf blower to HUGE 12-18 cylinder engines that power a large ship or a railroad train. There is no one answer to your question. A piston engine can weigh a few ounces to many tons.
Gasoline-fueled piston engines and turbojets.
