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.

Exclusive cars - only for the richest
Luxury car brand virtually since their inception are surrounded with an aura of mystery for average earners. Although over the years the exclusive, global brand cars were beginning to reveal its secrets to the outside world and show their offer, however, to this day, some car models are intended only for the richest people in the world. Luxury cars are a sign of prestige and good luck, while allowing very stand out in the crowd. Most of them are made of special materials and to achieve a surprisingly high speed. Another advantage of these cars is equipped with many different, sometimes very expensive gadgets.

Turbofan Jet Engine
Jet engines use a number of rows of fan blades to compress air which then enters a combustor where it is mixed with fuel (typically JP fuel) and then ignited. The burning of the fuel raises the temperature of the air which is then exhausted out of the engine creating thrust. A modern turbofan engine can operate at as high as 48% efficiency. 24
There are six sections to a Fan Jet engine:
Fan
Compressor
Combustor
Turbine
Mixer
Nozzle
