what does 3 valve engine mean?
438512
Unlike a two-valve engine, where there is only one intake valve, a three or four-valve setup allows manufacturers to design the engine in such a way that each intake valve opens at a slightly different time. The technique is also known as variable valve timing.

What does engine size mean? The size of an engine basically means the capacity its pistons have to push through air and fuel, across all of its cylinders. ... Engine size is rounded to the closest tenth of a litre, so a 1,020cc power unit would still be called a 1.0-litre engine, while a 1,160cc would be a 1.2-litre.

Every cylinder in an internal-combustion engine contains one intake valve and one exhaust valve. ... The intake valve is the larger of the two valves. It controls the flow of fuel into the combustion chamber. The exhaust valve controls the flow of exhaust gases out of the cylinder.

These valves are defined by the number of ports they use. 2 way valves, as their name suggests, consist of two ports: an inlet port “A” and an outlet port “AB.” On the other hand, 3 way valves consist of three ports: “A,” “B,” and “AB”.

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.

What Is The Difference? A 4 cylinder engine contains 4 pistons while a 6 cylinder contains 6, all driving the power of your engine. ... Four cylinder engines are typically inline engines (the 4 cylinders are in a straight line as opposed to a V shape like most 6 cylinder engines), making them smaller and lighter weight.

In internal combustion engines, variable valve timing (VVT) is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems.

Basically, the valves are opened by hydraulic pumps, which are operated by the ECU. The valves can open several times per intake stroke, based on engine load. The ECU then decides how much fuel should be injected to optimize combustion. At steady load conditions, the valve opens, fuel is injected, and the valve closes.
