What does exactly means when an engine is 1.6L, or 2.0L? I mean, what is 1.6L? A receptacle? A bottle of coke inside the engine?
In: Engineering
Your engine is basically a giant air pump. The internal volume of the engine tells you how much air can be pushed through the pump during a cycle, which gives a rough relationship with how much power it has (engine designers have a bunch of tools to get more work and power from a small engine).
It’s measured by subtracting the maximum and minimum volume of each cylinder and adding all the cylinders up.
When your engine fires, the expansion from burning fuel pushes one cylinder in the engine from the smallest volume to the largest, then the expanded gas is exhausted and the engine takes in new fuel and air (sometimes compressing it) and the cycle repeats. That expansion is what powers the car, or tool.
