Dijelovi automobila

[scooter21ba]

na jednoj temi sam se raspravljao kako se sta zove na autu pa da ne idemo offtopic odlucio sam otvoriti temu

sta je spojler ?
i kako je ispravno odbojnik branik ili karambolka?


svi ostali nazivi itd postavljajte pa da vidimo misljenja?

Spojler je uglavnom plasticni dio koji se ugradjuje na auto ili dolazi serijiski, a sluzi za pravilno usmjeravanje zraka radi bolje aerodinamike. S tim da kod nas vise od pola ljudi spojlere stavljaju nigdje veze!
A ovo troje je sve pravilno.

Jel se moze postavljati,kako sta radi,sta za sta sluzi i slicno da ne idem off ako ne moze

moze sve samo da odgonetnemo nazive dijelova auta i za sta sluze i gdje se nalaze

Jos malo o motorima


OHV, OHC ili SOHC i DOHC


OHV engine design


OHV means OverHead Valve - an engine design where the camshaft is installed inside the engine block and valves are operated through lifters, pushrods and rocker arms (an OHV engine also known as "Pushrod" engine). Although an OHV design is a bit outdated, it has been successfully used for decades. An OHV engine is very simple, has more compact size and proven to be durable.
Downside: it's difficult to precisely control the valve timing at high rpm due to higher inertia caused by larger amount of valve train components (lifter-pushrod-rocker arm). Also it's very difficult to install more than 2 valves per cylinder or implement some latest technologies such as Variable Valve Timing - something that could be easily done in a DOHC engine.




OHC or SOHC engine


OHC in general means OverHead Cam while SOHC means Single OverHead Cam.
In the SOHC engine the camshaft is installed in the cylinder head and valves are operated either by the rocker arms or directly through the lifters (as in the picture).
The advantage is that valves are operated almost directly by the camshaft - easy to achieve the perfect timing at high rpm. Also it's possible to install three or four valves per cylinder
The disadvantage - an OHC engine requires a timing belt or chain with related components - more complex and more






DOHC or Twin cam engine


DOHC or Double OverHead Cam - the setup used in many today's cars. Since it's possible to install multiple valves per cylinder and place intake valves on the opposite side from exhaust vales, DOHC engine can "breath" better meaning that it can produce more horsepowers with smaller engine volume. Compare: The 3.5-liter V6 DOHC engine of 2003 Nissan Pathfinder has 240 hp, similar to 245 hp of the 5.9-liter V8 OHV engine of 2003 Dodge Durango.
Pros: High efficiency, possible to install multiple valves per cylinder and adopt variable timing.
Cons: More complex and more expensive design.

nisam mislio na ovo al ajd neka ga
mislio sam na ono sta je to remen kais sta je spojler sta je branik kako se zove ono sto radi ono i sto stoji tu i tu al ajd fino je i ovo neka malo
ipak ne vjerujem da ce obicni vozaci ikad imati neku vecu dodir sa klipovima zamajcem itd itd

Pa moze , evo cim budem uhvatio malo vremena ja cu napisati svoje vidjenje sta je spojler
