Why do you need intake and exhaust valves in an engine?
Why do you need intake and exhaust valves in an engine?
The intake valves of course let air in, and the exhaust valves let exhaust air out. The more air you can move air in and out of the engine the more efficient, and therefor power the engine will have.
Why is the torque peak of an intake port important?
Because the torque peak represents maximum VE, we know that it is the point of greatest cylinder filling, highest charge density, and maximum exhaust volume. By optimizing intake port and exhaust port/header capability to match peak VE we achieve optimum system resonance at the point of maximum efficiency. Max torque follows accordingly.
What are the two types of engine valves?
There are two types of engine valves; intake and exhaust valves. The intake valves of course let air in, and the exhaust valves let exhaust air out.
What is the opening point of the intake valve?
Intake Opening: Looking at the intake valve, its opening point is critical to vacuum, throttle response, emissions, and gas mileage.

When do exhaust gases pass around the intake manifold?
When the engine is cold, all the exhaust gases pass around the intake manifold. When the engine is warmed up, a part of the exhaust gases goes around it, and when the engine is fully warmed up none of the exhaust gases passes around the intake manifold, but goes directly to the exhaust pipe as shown fig.

Where is the intake manifold on a V-8 engine?
The intake manifold has mounted a side of the cylinder block in L-head engines and on the side of the cylinder head in I-head engines. It is situated between the two cylinder banks on V-8 engines.
How does the damper work on the intake manifold?
The damper is controlled thermostatically to deflect the exhaust gases around the intake manifold. When the engine is cold, all the exhaust gases pass around the intake manifold.
The intake valves of course let air in, and the exhaust valves let exhaust air out. The more air you can move air in and out of the engine the more efficient, and therefor power the engine will have.

Is the intake manifold covered on a big block Chevy?
Some aftermarket intake manifolds don’t cover the upper opening, which does not cause any problems. All OEM big-block heads had an exhaust crossover passage for intake manifold heat and automatic choke operation, as well as supplying exhaust gas for EGR-equipped (exhaust gas recirculation) vehicles from the early 1970s on.
