Reciprocating
Classification
There are several possible ways to classify internal combustion engines.
Reciprocating:
By number of strokes
Two-stroke engine
Clerk Cycle 1879 6
Day Cycle
Four-stroke engine (Otto cycle)
Six-stroke engine
By type of ignition
Compression-ignition engine
Spark-ignition engine (commonly found as gasoline engines)
By mechanical/thermodynamical cycle (these 2 cycles do not encompass all reciprocating engines, and are infrequently used):
Atkinson cycle
Miller cycle
Rotary:
Wankel engine
Continuous combustion:
Gas turbine
Jet engine
Rocket engine
Ramjet
The following jet engine types are also gas turbines types:
Turbojet
Turbofan
Turboprop

Different vehicles - the different categories of driving license
There is no doubt that the most popular is the driving enabling management of passenger cars. Today, few who do not already have such a document. But there are many other categories of driving licenses, which entitle to drive other vehicles. Such courses are also conducted in the centers involved in the training of drivers of passenger cars. Why go for a license in a different category? Primarily related to an increase in opportunities. Those fascinated by motorcycles are not allowed to drive them without holding a driving license in the category. The same is true for buses and big trucks and other vehicles.
Ignition
Ignition
Internal combustion engines require ignition of the mixture, either by spark ignition (SI) or compression ignition (CI). Before the invention of reliable electrical methods, hot tube and flame methods were used. Experimental engines with laser ignition have been built.15
Spark Ignition Process
Bosch Magneto
Points and Coil Ignition
The spark ignition engine was a refinement of the early engines which used Hot Tube ignition. When Bosch developed the magneto it became the primary system for producing electricity to energize a spark plug.16 Many small engines still use magneto ignition. Small engines are started by hand cranking using a recoil starter or hand crank . Prior to Charles F. Kettering of Delco's development of the automotive starter all gasoline engined automobiles used a hand crank.17
Larger engines typically power their starting motors and Ignition systems using using the electrical energy stored in a lead?acid battery. The battery's charged state is maintained by an automotive alternator or (previously) a generator which uses engine power to create electrical energy storage.
The battery supplies electrical power for starting when the engine has a starting motor system, and supplies electrical power when the engine is off. The battery also supplies electrical power during rare run conditions where the alternator cannot maintain more than 13.8 volts (for a common 12V automotive electrical system). As alternator voltage falls below 13.8 volts, the lead-acid storage battery increasingly picks up electrical load. During virtually all running conditions, including normal idle conditions, the alternator supplies primary electrical power.
