What is valve actuating mechanism?
Mechanism with side camshaft and Mechanism with overhead camshaft both valve actuating mechanisms are used to operate inlet or exhaust valves.

Wt is the material used for inlet and exhaust manifold?
cast iron
What is the work of 4 valve in one cylinder head?
Two inlet and two exhaust valves. Multiple valves are usually used because they provide more efficient gas (read air/fuel mixture, or exhaust gas dependent on which valves) flow than one valve of the same surface area.
Why 2 springs used in inlet and exhaust valve in 4 stroke engine?
Two springs are used for the inlet and exhaust valves in a four-stroke engine to ensure reliable operation and better performance. The dual spring configuration provides enhanced valve control, reducing the risk of valve float at high RPMs, which can lead to engine damage. It also helps maintain consistent pressure on the valves throughout their operation, ensuring proper sealing and reducing wear. Additionally, using two springs can balance forces more effectively, improving overall engine efficiency.
What is a VW combi valve?
A combination valve is a pneumatically actuated shut-off valve. It is integrated into a valve housing and is typically used for blocking and releasing a flow between an inlet and an outlet
What is a valve grinder used for?
There are many things that a valve grinder is used for. Typically, a valve grinder is used for helping a fuel air mixture to come in and to exhaust the burned gasses.
Term inlet valve lead and the reson why it is used?
The term "inlet valve lead" refers to the timing of the inlet valve opening relative to the position of the piston in an internal combustion engine. It is crucial for optimizing engine performance, as it allows the intake air-fuel mixture to enter the combustion chamber efficiently at the right moment. By adjusting the inlet valve lead, engineers can enhance engine power, fuel efficiency, and overall responsiveness, ensuring that the engine operates effectively across different speeds and loads.
What are the functions ofengine inlet and exhaust manifolds?
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.
Why egr is not used where vvt is used?
no need to externally fitted EGR .Reason VVT have valve actuate various angle depends engine speed that time valve overlapp is high . in end of exhaust stroke both valve open condition exhaust gas easy to mix with fresh air . it acting on same as EGR
What is main inlet valve used in hydroelectric power plant?
Main inlet valve or shortly we say MIV is the spherical valve which installed before water enter into spiral casing of the hydro turbine.Water from the dam go to the penstock and before water enter the turbine, MIV is a component in between stop the water for small maintenance purpose in the turbine hall
What is the difference between valve and control-valve?
Control valve: Used to modify flow rate in a process control system.It has characterization: linear,equal percentage and quick opening Pressure inlet must be higher than the output pressure Regulator:Diapghram operating valve which controls outlet pressure (reducing application),control inlet pressure (back pressure) or either (differential reducing and differential relief applications
