Why invest in car navigation?
Although the market there are a lot of gadgets, which are available to the driver, most people reaching for automotive technical innovations selects navigation. It is without a doubt the most popular device, which allows for maintaining the route, even without knowing the map. What's more, most of the satellite navigation sets us some runs and we can decide, according to which we will go. Most people reach for this little device, above all, because it allows not to get lost in an unknown area; by navigation you can also quickly reach the destination in many cases. Fashion for having such a gadget automotive lasts for several years and so far, you can expect that these articles will continue to be very readily bought by drivers.
Most truck and automotive diesel engines
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.
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.
