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.Źródło: https://en.wikipedia.org/wiki/Internal_combustion_engine

Winnings in contests - why they are often associated with the automotive industry?

We can easily notice that the cars or motorcycles are very often one of the main prizes in various competitions or sweepstakes.
Why is it like that ? Well, these machines are often very valuable and can significantly make life easier for the winner.
So valuable prize is designed to encourage more participants to take part in the common play or boot from the competition.

However, one should check if the person you want to give away no longer has such a home. Available on the market, however, is much different proposals in this regard, that will certainly find something suitable, as well as inexpensive.
