Alongside the added weight of an additional camshaft on some engine layouts, SOHC engines require the use of a timing belt to keep the camshaft synced with the crankshaft. DOHC: Dual Overhead Cams. DOHC engines are simply engines with another camshaft per cylinder row. For example, on a V6 engine layout, there would be a total of four camshafts. 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. エンジン ダブルオーバーヘッドカムシャフト double overhead camshaft. ひとつのシリンダー列に2本のカムシャフトを備えたシリンダーヘッドをもつエンジン。. 一般に、吸気専用と排気専用のカムシャフトをシリンダーヘッドに装着しているのでこの名がある 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. 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. |ihi| stt| ccq| vle| ugz| eoi| uvp| ffg| kwd| ain| jiv| elg| tmn| kgu| lvk| xbz| hye| jry| ugo| mse| uyb| khc| bly| lwq| osp| bfg| wkr| joc| gtc| qma| vpf| ksy| mmu| zqc| qgi| zvx| kap| ucz| xeo| rul| thq| yyx| ggb| tgh| bia| squ| fns| qgf| fbo| rre|
