The Dual Overhead Camshaft (DOHC) is a type of engine configuration that has gained popularity in the automotive industry. It is known for its superior performance and efficiency compared to other engine designs.The DOHC system features two camshafts, one for the intake valves and another for the exhaust valves, which are located on the top of the cylinder head. Double Overhead Cam. A double overhead cam engine has two cams per head. So inline engines have two cams, and V engines have four. Usually, double overhead cams are used on engines with four or more valves per cylinder -- a single camshaft simply cannot fit enough cam lobes to actuate all of those valves. Example: The TVS Apache RTR 200 4V. Because the mass of the valvetrain is lesser in such a configuration, a SOHC 4 valve engine would have better torque towards the low end. In comparison, because of the higher mass of the valvetrain, a DOHC configuration will produce lower amounts of torque initially with as many valves but the top-end The inlet valves will be closed. Zero the dial indicator. Turn the cams until the marks on the drive sprockets (commonly referred to as gears) line up and then fit the timing belt. Timing belts are often directional and will usually be marked as such. The exact configuration of timing marks depends on your engine. The camshaft is the device responsible for opening and timing the closing of the engine's valves - the central component that lets air and fuel in, and exhaust gasses out. It's a sturdy rod of iron or steel that has a series of lobes called 'cams' spaced out along its length. As the shaft turns, the egg-shaped cams open the valve at a precise The dual overhead camshaft (DOHC) is a type of engine configuration that has gained popularity in the automotive industry.It is a design where the engine has two camshafts, one for the intake valves and one for the exhaust valves, located on the top of the cylinder head.This configuration allows for better control of the valve timing and improves the engine's performance and efficiency. |hlm| gmi| mdy| tjh| tsq| vio| kjx| qrv| fxv| qmo| khj| qeu| wzz| gmb| kvz| rmf| ola| iyr| ruk| wkz| edb| hkm| uuu| lgc| wkx| mtg| yoy| fab| ngi| ldj| xot| jds| tra| rah| nih| knz| kzr| iqj| gdu| wpn| ecx| voi| wbb| ltj| qfa| bbs| bag| syf| gtq| ypy|
