It is in the cylinder head.
Mainly, the difference is that in an overhead cam engine, the camshaft is mounted on the head of the engine, and the valves are still overhead, in an overhead valve engine (sometimes called a "pushrod motor"), the camshaft is in the crankcase.
The camshaft is typically located within the engine, either in the cylinder head (overhead camshafts) or in the engine block (overhead valve configurations). Its primary function is to control the opening and closing of the engine's intake and exhaust valves in sync with the pistons' movements. The precise location can vary depending on the engine design, such as whether it is a single overhead cam (SOHC) or a double overhead cam (DOHC) configuration.
In a dual overhead cam (DOHC, twin cam, etc.) engine, the intake cam is the camshaft contolling the intake valves. Thus the opperation of the exhaust valves is left to the exhaust cam.
It is an engine that has it's one and only cam shaft in the head above the valves. Instead of having it below in the block. A double overhead cam has two cams in each head.
Do you mean Dual Overhead Cam and Overhead Valve. Overhead Valve has the camshaft positioned just above the Crankshaft in the block of the engine and uses Pushrods to actuate the valves. Overhead Cam(Single Camshaft) and Dual Overhead Cam(Twin Camshafts) have the Camshaft positioned in the head directly over the valves. As a rule of thumb OHV(Over Head Valve) engines have smaller and shorter heads while SOHC(Single Over Head Camshaft) and especially DOHC(Dual Over Head Camshaft) engines have much wider and taller heads to fit the camshafts and their accessories. Sometimes you can tell by spark plug positioning but this is not always accurate. Most OHV have the spark plugs on the sides of the heads with the distinct exception of HEMI heads. DOHC usually have the plugs in a North-South(Up-Down) arrangement.
The Saturn 4 cylinder engines were available in 2 styles, the single overhead cam and the dual overhead cam. In both engine types, the camshafts were always in the head, just under the top cover of the engine. If you remove the top cover (where you install the sparkplugs) you will see the camshaft(s).
Its a single cam.. it says " 2.0 Split Cam on the cover of the engine... A dual cam would say " 16V Zetec" on the engine cover.
A twin cam is an engine that has two cam shafts (which open and close the valves). The most common reasons for two camshafts are: If a V-shaped engine design uses one cam shaft for each side of the V - obviously, if a V engine has overhead cams, you would need a cam at the top of each side of the V. Also, a straight in-line engine with two intake valves and two exhaust valves per cylinder might use twin camshafts. Actually, I V-6 or V-8 engine with one camshaft on each head in a overhead cam configuration is still considered a single overhead cam. The only time an engine is classified as a twin cam or double overhead cam is when there are two camshafts on each cylinder head. A double overhead cam V-6 engine would have a total of four camshafts. Two for each head.
The Z24 has a 2.4 L engine that is a Dual Overhead Cam engine. The other models have the 2.2 L engine that is Single Overhead Cam engine.
The camshaft is typically located in the engine, either in the cylinder head (overhead camshaft) or in the engine block (cam-in-block configuration). Its primary function is to control the timing of the opening and closing of the engine's intake and exhaust valves. In modern engines, camshafts are often driven by a timing belt or chain connected to the crankshaft.
Yep.
