What it Camshaft? A camshaft is a tool used in piston engines to run valve or valves. As the picture below shows there are some bumps pointed. And it used to depress the valve "visor" exhaust or suction. This camshaft located in the cylinder head.
After that, what the acronym SOHC and DOHC. It's Simple ... SOHC namely "Single Over Head Cam" while DOHC is "Double Over Head Cam". Of these abbreviations, we can guess that SOHC has a Single Camshaft. And DOHC has a Dual Camshafts. That's all?
Both types of machines still used by many manufacturers, according to various needs, and not also mean it is not a good SOHC by DOHC. Some reasons remain to be used between the two types of machines.
In contrast to the DOHC, SOHC still uses the trigger to depress valve. DOHC was no longer using the trigger again because each camshaft has been divided into two parts, and immediately played through the swivel ring that is connected to the machine.
LACK OF EXCESS "SOHC" AND "DOHC"
Excess SOHC
- Classified as more efficient fuel
- The price of this machine is cheaper.
- Cheap Treatment
- Workers at a large round bottom
- Machines become lighter due to the use of a single Camshaft.
Disadvantages SOHC
- Round up the lower RPM
- The sound produced is greater
- Lose power on lap top
excess DOHC
- Ability to move the valve stably
- Sucking maximum fuel
- Power output is greater
- Round maximum high engine
Disadvantages DOHC
- The price of these types of machines are relatively more expensive
- Machines become more severe
- Relatively wasteful of fuel
- Part more expensive
- Treatment relatively more difficult
Well ... now you know the differentiations of SOHC and DOHC.
I think SOHC engine is more suitable for city or touring.
