2. Component parts of internal combustion engines - Wikipedia

   en.wikipedia.org/wiki/Component_parts_of...

   A piston is a component of reciprocating engines. It is located in a cylinder and is made gas-tight by piston rings. Its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In two-stroke engines the piston also acts as a valve by covering and uncovering ports in the cylinder ...

3. Engine control unit - Wikipedia

   en.wikipedia.org/wiki/Engine_control_unit

   The Ford EEC (Electronic Engine Control) system, which utilized the Toshiba TLCS-12 microprocessor, went into mass production in 1975. [ 7 ] The first Bosch engine management system was the Motronic 1.0 , which was introduced in the 1979 BMW 7 Series (E23) [ 8 ] This system was based on the existing Bosch Jetronic fuel injection system, to ...

4. Piston - Wikipedia

   en.wikipedia.org/wiki/Piston

   Consequently, steam engine pistons are nearly always comparatively thin discs: their diameter is several times their thickness. (One exception is the trunk engine piston, shaped more like those in a modern internal-combustion engine.) Another factor is that since almost all steam engines use crossheads to translate the force to the drive rod ...

5. Two- and four-stroke engines - Wikipedia

   en.wikipedia.org/wiki/Two-_and_four-stroke_engines

   The M4+2 engine, also known as the double-piston internal combustion engine, is a type of internal combustion engine invented by Polish patent holder Piotr Mężyk. [1] The M4+2 engine took its name from a combination of two-stroke engines and four-stroke engines. The two-stroke combustion engine is characterized by a simple construction and ...

6. Reciprocating engine - Wikipedia

   en.wikipedia.org/wiki/Reciprocating_engine

   Ray-traced image of a piston engine. There may be one or more pistons. Each piston is inside a cylinder, into which a gas is introduced, either already under pressure (e.g. steam engine), or heated inside the cylinder either by ignition of a fuel air mixture (internal combustion engine) or by contact with a hot heat exchanger in the cylinder (Stirling engine).

7. Engine tuning - Wikipedia

   en.wikipedia.org/wiki/Engine_tuning

   Engine tuning is the adjustment or modification of the internal combustion engine or Engine Control Unit (ECU) to yield optimal performance and increase the engine's power output, economy, or durability. These goals may be mutually exclusive; an engine may be de-tuned with respect to output power in exchange for better economy or longer engine ...

8. Aircraft engine controls - Wikipedia

   en.wikipedia.org/wiki/Aircraft_engine_controls

   Cowl flap position control - Cowl Flaps are opened during high power/low airspeed operations like takeoff to maximize the volume of cooling airflow over the engine's cooling fins. Cylinder head temperature gauge - Indicates the temperature of all cylinder heads or on a single CHT system, the hottest head. A Cylinder Head Temperature Gauge has a ...

9. Dead centre (engineering) - Wikipedia

   en.wikipedia.org/wiki/Dead_centre_(engineering)

   In a reciprocating engine, top dead centre of piston #1 is the point from which ignition system measurements are made and the firing order is determined. For example, ignition timing is normally specified as degrees of crankshaft rotation before top dead centre (BTDC). [2]
