How does engine size affect petrol consumption in a car? Many people assume that a bigger engine means better petrol consumption but it does not affect it as much. Here is a guide on the engine size and its effects on petrol.

What does Engine Size Mean?

The size of an engine refers to the engine capacity, ie the total volume of cylinders. Larger engines have more space for fuel than smaller engines. An engine is measured according to the liters it holds and its power is also determined by this size. Many may assume that larger older cars have a powerful engine that is cheaper than modern cars, however, this isn’t necessarily the case. Due to recent developments in engines, smaller cars have more horsepower than they used to have while consuming less fuel. Cars like Toyota Etios and Suzuki Ignis have powerful turbocharged engines and are better equipped than older, bigger engines.

Cylinders

The power unit of engines is determined by their cylinder. The more power and cylinders it has, the more power it has. Most cars have a cylinder count of four, six, or eight. Cylinders determine the effect of petrol used and engines with more cylinders will use more air and an increasing amount of fuel. What this means is that engines with fewer cylinders will produce a better fuel economy.

Know the Difference of Numbers Like 2.0, 1.2 and 1.3

Numbers like 2.0, 1.2, and 1.3 refer to the engine’s capacity and the number of cylinders. As explained, the greater number of cylinders, the great the engine power. Choosing a larger engine is therefore not always necessary when determining the fuel consumption in a car. A larger engine may consume more fuel than a smaller engine (and that’s not including the higher purchasing costs of owning a bigger-engineered car). A less powerful engine will save you money on fuel and everyday trips – which is also an added reduction in Co2 emissions, making it a better choice for the environment.

Of course, your car’s engine size is not the only factor determining the effect on petrol. Your driving style also affects your fuel consumption, as well as your tire maintenance and inflation.
