2. Aircraft engine starting - Wikipedia

   en.wikipedia.org/wiki/Aircraft_engine_starting

   Hand starting of aircraft piston engines by swinging the propeller is the oldest and simplest method, the absence of any onboard starting system giving an appreciable weight saving. Positioning of the propeller relative to the crankshaft is arranged such that the engine pistons pass through top dead centre during the swinging stroke.

3. Starter (engine) - Wikipedia

   en.wikipedia.org/wiki/Starter_(engine)

   An automobile starter motor (larger cylinder). The smaller object on top is a starter solenoid which controls power to the starter motor and engages the Bendix drive.. A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power.

4. Air-start system - Wikipedia

   en.wikipedia.org/wiki/Air-start_system

   A direct start system as used on a marine slow-speed diesel is required to have up to 12 starts on a non-reversing engine or 6 starts on a reversible, or geared, engine. When starting the engine, compressed air is admitted to whichever cylinder has a piston just over top dead center, forcing it downward. [2]

5. Coffman engine starter - Wikipedia

   en.wikipedia.org/wiki/Coffman_engine_starter

   The Coffman engine starter (also known as a "shotgun starter") was a starting system used on many piston engines in aircraft and armored vehicles of the 1930s and 1940s. It used a cordite cartridge to move a piston, which cranked the engine.

6. Rope start - Wikipedia

   en.wikipedia.org/wiki/Rope_start

   Starting a Lazair II ultralight aircraft's JPX PUL 425 engine, equipped with a recoil starter. A rope start device housed in a Nose bullet of a Junkers Jumo 004 turbojet.. Rope start (also called ripcord [citation needed], pull start [citation needed], or rewind start [citation needed]) is a method of starting an internal combustion engine, usually on small machines, such as lawn mowers ...

7. Compression release - Wikipedia

   en.wikipedia.org/wiki/Compression_release

   The most common kind of small engine compression release uses a camshaft mounted mechanical lever that pushes the exhaust valve tappet slightly, venting engine compression through the exhaust valve. Once the engine spins to starting speed, centrifugal force causes the lever to move out of the way, and the exhaust valve is allowed to seat fully.

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

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

   The focus of breaking in an engine is on the contact between the piston rings of the engine and the cylinder wall. There is no universal preparation or set of instructions for breaking in an engine. Most importantly, experts disagree on whether it is better to start engines on high or low power to break them in.
