History
Main article: History of the internal combustion engine
Etymology
At one time, the word engine (from Latin, via Old French, ingenium, "ability") meant any piece of machinery ? a sense that persists in expressions such as siege engine. A "motor" (from Latin motor, "mover") is any machine that produces mechanical power. Traditionally, electric motors are not referred to as "Engines"; however, combustion engines are often referred to as "motors." (An electric engine refers to a locomotive operated by electricity.)
In boating an internal combustion engine that is installed in the hull is referred to as an engine, but the engines that sit on the transom are referred to as motors.3

Motorcycle driver's license
Difficulties in obtaining the right to drive a motorcycle may result already from the fact that he sat on a motorcycle we need to maintain balance. Not everyone is easy to achieve. On the basis of the fact that - from the need to maintain a balance, and ending with the fact that driving license for motorcyclists is difficult, because the instructor is not in the same vehicle, every student - we can say that getting a license for a motorcycle requires really a lot of effort. However, this does not discourage people who want to manage their own engine. It is true that, during the practical lessons in this category may appear to be much more problematic and dangerous events, but this challenge can be met through a systematic science.
Most truck and automotive diesel engines
Diesel cycle
Main article: Diesel cycle
P-v Diagram for the Ideal Diesel cycle. The cycle follows the numbers 1?4 in clockwise direction.
Most truck and automotive diesel engines use a cycle reminiscent of a four-stroke cycle, but with a compression heating ignition system, rather than needing a separate ignition system. This variation is called the diesel cycle. In the diesel cycle, diesel fuel is injected directly into the cylinder so that combustion occurs at constant pressure, as the piston moves.
Otto cycle: Otto cycle is the typical cycle for most of the cars internal combustion engines, that work using gasoline as a fuel. Otto cycle is exactly the same one that was described for the four-stroke engine. It consists of the same four major steps: Intake, compression, ignition and exhaust.
PV diagram for Otto cycle On the PV-diagram, 1?2: Intake: suction stroke 2?3: Isentropic Compression stroke 3?4: Heat addition stroke 4?5: Exhaust stroke (Isentropic expansion) 5?2: Heat rejection The distance between points 1?2 is the stroke of the engine. By dividing V2/V1, we get: r, where r is called the compression ratio of the engine.
