Extension Of DOHC And Its Function

YOGYAKARTA - For the community, the term DOHC may be familiar, because it is often listed on motorbikes or cars. However, not all people understand the meaning of the term used.

DOHC stands for one type of engine used in vehicles. The extension of DOHC itself is the Double Overhead Camshaft or the double top steering axis. Currently, DOHC itself is widely adopted by world car manufacturers, especially in the production of the latest cars.

What exactly is the function of DOHC? And what is the system or how it works? To answer this question, see the explanation below.

As previously explained, Camshaft's Double Overhead stands for DOHC. DOHC is a new type of machine developed by automotive experts as opposed to SOHC machines.

DOHC itself has several quite important functions in the car. Below is the full function.

The function of the next DOHC is to increase fuel burning to make it more efficient. This certainly has a major impact on reducing exhaust emissions so that cars are more environmentally friendly. This condition can occur because in the DOHC car engine, there are two steering axes (camshafts) that control the opening valves in each engine cylinder so that fuel burning will be more efficient.

The main function of DOHC in cars can be said to be the main driver in producing wheels and power.

In addition to improving engine performance, DOHC can also make car speed increase. Even cars can reach higher RPM and top speed. This condition can occur because in DOHC there are four klepts or valves (2 fuel valves and 2 gas disposal valves) and two nokens.

The DOHC engine can provide a much larger and more responsive power in engine performance. This can happen because there are many opening valves and components that are more precise and accurate. So the engine performance will increase.

The DOHC engine on the car has its own way of working, and it can be said to be more complex than how its predecessor worked, the SOHC machine (machine with two valves and one noken as). The working mechanism of the DOHC engine on the car, begins when the piston moves from the TMA (The Top Dead Spot) to the TMB (LOW Dead Point) at the time the valve (klep) condition opens and the valve (klep) comes out closed. Thus, the incoming valve can suck air and carry it into the combustion chamber.

The next step, the piston will move from the TMB (Land Dead Point) to the TMA ( Top Dead Point) when the valve condition (klep) comes out and enters in a closed position simultaneously. This condition makes the air in the combustion room undergo a compression process.

Before the piston goes up to TMA (Titik Mati Atas 0), there will be a timing ignition process. The process is marked by a busi that lights up and burns the air (gas) in the fuel room. So that the air pressure on the fuel chamber will increase so that it drives the piston from TMA to TMB. At this time, the power to move the engine is obtained.

That's the review of the extension of DOHC. Hopefully useful. Visit VOI.id to get other interesting information.
