   A PTO at the rear end of a farm tractor A PTO (in the box at the bottom) in the center of the three-point hitch of a tractor. A power take-off or power takeoff (PTO) is one of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machine.

3. Break-in (mechanical run-in) - Wikipedia

   en.wikipedia.org/wiki/Break-in_(mechanical_run-in)

   The break-in can take place either in the vehicle or on an engine stand. Each engine has specific preparation needs of its own due to factors such as the many different types of engine models, the vehicles it belongs to, and conflicting expert instructions. For example, each engine should be lubricated and run on oil specified by its designers ...

   Engine stand (red) holding a partially disassembled combustion engine. An engine stand is a tool commonly used to repair large heavy gasoline or diesel engines.It uses a heavy cantilevered support structure to hold the engine in midair so that the mechanic has access to any exposed surface of the engine.

   The engine features active turbine clearance control providing the optimal level of cooling air for different phases of flight. [ 18 ] At take-off, the fan displaces up to 1.3 t (2,900 lb) of air per second, the jet nozzle velocity is almost 1,000 mph (450 m/s) and each high pressure turbine blade generates around 800 hp (600 kW), rotating at ...

7. Internal combustion engine - Wikipedia

   The flame is "quenched" by the relatively cool cylinder walls, leaving behind unreacted fuel that is expelled with the exhaust. When running at lower speeds, quenching is commonly observed in diesel (compression ignition) engines that run on natural gas. Quenching reduces efficiency and increases knocking, sometimes causing the engine to stall.
