Understanding the Role of Engine Valves in Vehicle Performance

The engine valves are not very large in size, but they have an important role in supporting the performance of your vehicle, its efficiency and long life. Being one of the main manufacturers of engine valves and hydraulic valve tappets, the Suzhou Topu Engine Parts Co.,Ltd. appreciates how these important tiny parts impact on the engine functioning. This blog will discuss the roles, operation and effects of engine valves on performance and how they may require any maintenance.

What Are Engine Valves and How Do They Work?

Engine valves Engine valves (intake and exhaust valves) are mechanical gates that regulate the entry of air and fuel into the combustion chamber, and the escape of exhaust gases. They open and close together with those of the engine pistons and this assures ideal combustion.

Intake Valves: Air-fuel mixture let into the cylinder.

Exhaust Valves: Employ in liberating burnt gases during combustion.

Such valves are used together with hydraulic valve tappets (or lifters), which allows keeping zero clearance between valve stem and camshaft to minimize wear and noise. Valves that work fine bring about smooth running of the engine, economy, and power.

The Impact of Valve Timing on Engine Efficiency

The way valves are opened and closed correctly, that is, valve timing, directly influences the work of the engine. When the timing is faulty, then your engine can experience the following:

Lost Power: Inferior intake of air-fuel mixture results in low combustion.

Enhanced emissions: when the exhaust valve timing is incorrect the fuel will not be burned, and seep through.

Increased Fuel Use: The engine has to struggle due to poor operation of valves.

Newer engines employ the technology of Variable Valve Timing (VVT) in which the valves are adjusted to operate best at each speed, enhancing power as well as fuel consumption.

Signs That Your Engine Valves Need Maintenance

Bad valves would cause great damage to an engine especially when neglected. Be on the look out of these red flags:

Valve Wear/Bends: Combustion is disrupted by valves which are worn or bent.

Power loss: Weak sealing minimizes compression.

Ticking Sounds: Pumped up hydraulic tappets, or too much valve clearance.

Oversized Oil Use: The oil can burn due to leakage in the valve seals.

Some preventive repairs such as adjustment of valve clearances and timing belt are simple repairs which can be carried out to prevent expensive repairs.
