Inlet manifolds are actually called intake manifold and this is to allow air to be injected into the fuel for either a rich or lean mixture for either performance or gas mileage (which can be adjusted). The Exhaust manifold is used to expel your burnt fuel, or air/fuel mixture, during the exhaust stroke on a 4-cycle engine to allow room for the intake stroke to bring in your fuel, or air/fuel mixture. The exhaust manifold simply directs the exhaust and become extremely hot. The exhaust is pushed out by the exhaust stroke.
Air does not come out of an intake mainfold, because the intake manifolds are under a vacuum. Now exhaust manifolds, that a different story.
this is a mechanics job you have to remove inlet manifold,exhaust manifolds,and then remove heads to replace the valves
The crossover pipes on a 7.3 ford diesel engine are the pipes connecting the exhaust manifolds to the turbo compressor inlet.
With No1 cylinder at TDC adjust the following valve clearances, No. 1, inlet and exhaust No. 2, inlet No. 3, exhaust No. 4, inlet No. 5, exhaust Then turn the crankshaft 1 full turn so that No 6 cylinder is at TDC and adjust the following valve clearances, No2. , exhaust No. 3, inlet No. 4, exhaust No. 5, inlet No. 6 inlet and exhaust. Both inlet and exhaust clearances ar 0.4 mm with engine cold. This info is from the original service manual
Start with undressing the cylinder head inlet and exhaust manifolds get a container for bolts and any other small stuff undo all of the cylinder head studs and lift off the cylinder head.
An inlet and exhaust valves are two separate things. The inlet valve lets the fuel/ air ,ix into the cylinder. The exhaust valve opens to let the pressure out after the mix has burned, releasing the gasses. Then the process starts over again.
Hi, inlet is 25mm and exhaust is 22mm
The air/gas mixture from the carb is drawn into the cylinder through the Inlet manifold. The inlet manifold is designed so that there is sufficient volume of air/gas to meet the engine needs at all revs. Each branch is designed to create minimum air turbulence thus allowing the intake mixture to be sufficiently abundant at high revs to prevent power tail off. The exhaust gasses are forced through the Exhaust manifold to the exhaust pipe. The exhaust manifold and exhaust system are designed to over handle the volume of exhaust gasses so that there is not a loss of power at high revs. Exhaust manifolds, helped by the cylinder firing order, have even heat dissipation to prevent cracking.
the difference is that the inlet valve takes air (oxygen) from surrounding in order to combution of fuel which result in blast by air fuel mixture and piston rotates while the exhaust gases removed from the exhaust valve.again the inlet valve opens first before blast and exhaust valve opens afterward
yes
metal (steel)
angle of the exhaust is to produce more power like the toyota supra almost all the exhaust are angled out so they get better flow which means more power the inlet is for different types of pipes like 2 inch inlet for a civic and 3 inch inlet recommended for turbo performance cars. inlets are to fit multiple different types of cars
