Why do engines have 4 valves per cylinder?

4 valves per cylinder allows for more airflow than 2 valves per cylinder, as there is larger open area when the valves are open. With the prevention of valve float, engines can rev higher and produce more power. The advantages of two valves per cylinder is a reduction of parts, thus saving cost and complexity.

Is more valves per cylinder better?

While enhanced engine breathing owing to better air flow is one of the biggest advantages of more valves per cylinder, it’s not the only one. Being lighter, the smaller valves also put lesser pressure on the camshaft lobes which control their lift, and if well-engineered, can enhance the durability of the engine.

How does a 4 valve cylinder work?

This technology incorporates Four Valves, two each of the inlet and exhaust valves in the engine. So, two inlet valves mean more opening of the area to suck the air-fuel mixture. The two inlet valves increase the area of the air intake. It allows more air-fuel mixture to get into the cylinder.

What is meant by 4 valve engine?

A four-valve setup is more commonly used on modern bikes or performance motorcycles. The configuration comprises of two large intake valves and two small exhaust valves. Generally, a four valve engine requires a DOHC (Double Overhead Camshaft) or two cams setup.

What is the difference between cylinder and valve?

The cylinder is the power unit of the engine. The inlet valve is where the fuel and air enter the cylinder from the carburettor or electric fuel injector, and the outlet valve is where exhaust gases escape. The exhaust gases created during combustion in the cylinder rotate an axle known as the crankshaft.
