How Engine Sizes Are Calculated

The displacement of an engine is the total internal volume of the cylinders at the bottom (i.e. minimum compression point) of the piston’s stroke.

Thus, a 2.4-litre straight 4 in your Camry will have a single row of four cylinders, each with an internal volume of 600ml. The 1.8-litre engine in your Corolla has a single row of four cylinders as well, each with an internal volume of 45oml.

You can have 1.2, 1.6 and 1.8 litre variants of the same block; the cylinders simply have thinner or thicker walls.

The external size of an engine isn’t a reliable guide to its internal displacement, because the latter only takes into account the size of the holes bored or cast into the cylinder block.

A full engine also includes the cylinder head or heads, manifolds, camshaft and rocker covers, pumps, filters, coolant inlets and outlets, mounting points for other components……and that, is why a 2-litre engine is a lot bigger than 2 litres!

CAR 101: The Four Stroke Engine

So now that we know all the basic parts of the engine, let’s take a look at the movement that actually makes our car move: the four-stroke cycle. Please read our earlier article : The anatomy of the engine . Each piston travels through four strokes to complete a single cycle. Any given cycle is the succession of operations that are constantly being repeated in a cylinder when the engine is running. And a stroke can be defined as the piston moving from the point where it’s the highest in the cylinder to the lowest point in the cylinder, or vice-versa. The above illustration shows the four-stroke cycle in a single cylinder. This is going on in the other cylinders as well. Engines may have 3, 4, 6, 8, 12 or 16 cylinders in "V" or "W" configurations. Repeat this cycle a thousand times in a minute, and you get a car that moves. Twitter and Instagram; @VverteAutoSevcs Email; vverteautosevcs@gmail.com Phone; 09137103730 <script async ...
