The engine is the heart of a traditional internal combustion engine. Gasoline burned inside the cylinder and generated power to move the vehicle. When we are planning to purchase a new gasoline vehicle, we mainly look for its cylinder capacity. Because it determines the vehicle power, speed, and fuel consumption, you may know that it affects the engine parts’ lifetime.

01. What is cylinder capacity?

The majority of the vehicles running in the world still run on internal combustion engines. There’s a small part of the electric vehicles. In an electric car, its power is given to the wheels by the motors. There can be two motor or four motor vehicles.

In simple words, Cylinder capacity is the combined capacity of the total cylinders in an internal combustion engine. Let’s talk about it more profoundly in a technical way. The total capacity of the cylinders under the piston head (where it can fill fuels for burn) in an engine is simply referred to as the cylinder capacity.


02. What is two litter, 2.0 litter, 1.5L engine, or 1499cc engine, means (L vs. CC in the engine)?

It’s the total gasoline that can fill in inside the engine’s cylinders. Like Cylinder capacity measured in CC, gasoline capacity is measured in liters (L). CC means cubic centimeters. If we talk about it deeper, if the vehicle has a 2L 4-cylinder engine, then each cylinder has a capacity of 500cc (2,000/4=500). So each cylinder can fill 500ML gasoline.

Then we call it 2,000 CC or 2L engines. Although it does not completely fill the fuel in practice, each cylinder fills with air and a bit mix of fuel. It fills according to the air-fuel ratio (AFR). Petrol or Diesel engine has different AFR, petrol engine AFR is 14.7:1, and Diesel Air-Fuel Ratio is 14.5:1. That’s a standard ratio, but it can change.


03. Cylinder capacity and power.

The gasoline engine’s power is determined by the total capacity of each cylinder in an engine. The large engine has the ability to burn more fuel in its cylinders and generate more power than the smaller engines. So large engine has more RPM (revolution it turns in a minute).

Here, you may think that higher engine power has a higher speed, but it’s not always true. For example, heavy load transporting vehicles such as trucks, tippers, buses, the train has higher engine capacity, than cars, SUV, hatchbacks, but their speed considerably low. These heavy-duty vehicle engines need to pull the weight of the vehicles before they go faster.


04. Cylinder capacity and speed

As mentioned earlier, the engine of a vehicle basically expects not only speed but a lorry with a lot of noise is not going as faster. In these heavy automobiles, cylinder capacity is used more to pull the weight of heavy vehicles. Also, regardless of the number of cylinders in the vehicle, the gearbox gets more power to control the vehicle’s speed. Thanks to today’s new technology (gearbox), lower cylinder capacity vehicles can get a higher speed.


05. Put more weight on smaller engines.

It’s not suitable for loading more weight than the recommended size of a vehicle, especially for vehicles with small engine capacity. If you put too much weight on a longer period of time, it can cause the engine to run out quickly, and the longer run can expect more services. If you are planning to purchase a vehicle for heavy loads, you better go for a higher engine capacity.


06. Durability and capacity.

In this case, even if the cylinder capacity is low, the engine will wear out quickly as the engine gets more tired even if the speed is adjusted through the gearbox from other gimmicks. Simply put, when the engine is running at a low speed, the engine always needs to run at its maximum working capacity. As a result, vehicles with low engine capacity wear out quickly. In the case of cars, vehicles with a slightly larger cylinder capacity are less likely to pay, as they always run on less power.


07. Oil and engine size.

When the engine size exceeds 1500 cc, its fuel consumption is significantly reduced in cars. In other words number of miles it can run per gallon is reduced dramatically. Accordingly, the smaller engine has better fuel consumption. Although it has a few drawbacks, a lower engine size has less comfortable. For instance, Range Rover (which has a 2,995cc engine capacity) has better comfortability than the Audi hatchback A1 (which has a 1,390cc engine capacity).

If you consider using a car for your everyday uses with a better fuel economy without heavy loads, you can go for small engine-sized cars. If you overuse the small engines, then you can expect early maintenance than the manufacturer’s recommended time; for instance, use heavy load.
