THERE ARE SMALL HOLES IN THE TIMING GEARS THAT LINE UP WITH MARKS ON THE FRONT OF THE HEAD. When the crank pulley is at TDC on the compression stroke, 'E' & 'I' on the camshaft sprockets should be at 12 o'clock.
DOHC. Obviously a v-6 or v-8. DOHC- Double OverHead Camshafts. 2 camshafts per cylinder head.
Real simple exhaust camshafts are the camshafts nearest the exhaust manifolds ( outside if cylinder heads) intake camshafts are on the inside closer to center of engine.
DOHC means Double Over-Head Cam. The engine has 2 camshafts that are located within the cylinder head at the top of the engine.
In a V-type engine, there can be one or two camshafts per bank of cylinders, depending on the design. A V-type engine with a single overhead cam (SOHC) has one camshaft per bank, while a double overhead cam (DOHC) configuration features two camshafts per bank. Therefore, a typical V6 engine may have 2 to 4 camshafts, and a V8 engine may have 4 to 8 camshafts.
To align the camshafts for timing on a Renault Espace, first ensure the engine is at top dead center (TDC) on the compression stroke of cylinder one. Use the timing marks on the camshaft sprockets and the engine block to align the camshafts correctly; there are usually specific alignment marks or notches on both the camshaft gears and a timing cover. After confirming the alignment, secure the camshaft sprockets with the appropriate bolts before rotating the engine by hand to ensure there are no interference issues. Finally, double-check the alignment before reassembling all components.
the wankle engine has no camshaft
DOHC means double overhead cams,which means two camshafts on top of one cylinder bank. 4.6l is the engine displacement.
A single overhead camshaft V-8 has 2 camshafts, one on each head.
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.
Camshafts can be driven by a timing belt, timing chain, or gear mechanism. These mechanisms transfer power from the engine's crankshaft to the camshaft to control the opening and closing of the engine's valves.
It could have one, two or four cams. Depends on the engine
To determine the correct orientation of the camshafts in a 1992 4sfe engine, consult the engine's service manual or a reputable automotive repair resource specific to your vehicle model. Additionally, markings or notches on the camshafts and engine block can indicate their proper alignment. It is vital to follow the manufacturer's guidelines and specifications to ensure correct installation.
