If the clearance in a valve mechanism is too large, it can lead to delayed valve opening and closing, resulting in inefficient engine performance. This excessive clearance may cause a loss of precision in timing, leading to incomplete combustion and increased emissions. Additionally, it may result in increased wear and tear on the components, potentially reducing the overall lifespan of the engine.

What would be the effect on valve opening if the clearance was st to large?

If the clearance on a valve is set too large, it can lead to delayed valve opening and closing, resulting in reduced engine performance and efficiency. This excessive clearance can cause a loss of compression and lead to increased wear on the valve train components. Additionally, it may result in a rough idle and poor fuel economy due to improper timing of the valve events. Overall, maintaining proper clearance is crucial for optimal engine operation.


What is effect for opening valve when clearance volume was set too small?

When the clearance volume is set too small, opening the valve can lead to excessive pressure buildup within the combustion chamber. This can result in premature valve opening or even valve damage due to increased stress. Additionally, insufficient clearance may cause incomplete combustion or misfires, adversely affecting engine performance and efficiency. Ultimately, it can lead to mechanical failure if not addressed.


What would be effect on valve opening if the clearance was set too large?

If the clearance on a valve is set too large, it can lead to insufficient sealing when the valve is closed, resulting in increased leakage and reduced efficiency in the system. Additionally, the valve may not open fully or respond properly, affecting the timing and performance of the engine or mechanical system it controls. This can ultimately lead to decreased power output, increased wear on components, and potential failure of the system over time.

Why must there normally be a clearance between the end of a valve an its opening mechanism?

There must normally be a clearance between the end of a valve and its opening mechanism to ensure smooth operation and prevent jamming. This space allows for thermal expansion, tolerances in manufacturing, and potential misalignments during installation or operation. Additionally, the clearance helps to accommodate any debris or contaminants that may enter the valve area, ensuring reliable functioning without hindrance.
