Automobile Desk: While liking a new car in the showroom, our eyes first fall on the shining alloy wheels, sunroof, big touchscreen and safety features. After this, the budget and mileage are calculated, but very few people pay attention to the most important part of the vehicle i.e. its engine. Most buyers get confused when a sales executive mentions a 3-cylinder or 4-cylinder engine. It is generally believed that more cylinders means more power and less cylinders means better mileage. But the reality is quite different from this. The number of cylinders in an engine has a direct impact on your daily driving, vehicle maintenance and travel comfort.
Role of cylinder within engine
To understand the functioning of any petrol or diesel engine, it is important to know the role of the cylinder. The cylinder is a closed part of metal, within which the piston moves rapidly up and down. In this chamber, the mixture of air and fuel explodes, the energy generated from which works to rotate the wheels. The engine which has three such chambers and three pistons is called a 3-cylinder engine. At the same time, the setup with four pistons is called 4-cylinder engine. On paper, it appears to be a difference of just one part, but as soon as they hit the road, the behavior of both changes completely.
3-cylinder engine: combination of economy and lightness
In today's era, the use of 3-cylinder engines has increased rapidly from entry-level hatchbacks to compact SUVs. The biggest reason for this is its compact size and low weight. Due to less parts in the engine, the manufacturing cost of automobile companies gets reduced, which directly benefits the customers in the form of lower prices.
These engines do not disappoint even in terms of fuel economy. Due to low friction and light weight, they provide good mileage in city traffic. However, it is not certain that every 3-cylinder car will give more mileage; It also depends on the total weight of the vehicle, the tuning of the gearbox and the way you press the accelerator. Its biggest practical drawback is engine noise and vibration. Having three pistons causes the engine's natural balance to waver a bit, which can lead to a slight tingling sensation in the steering wheel and cabin when idling. Also, if there are five people sitting in the car and one has to travel on uphill roads, then the lack of power in the normal 3-cylinder engine without turbo is clearly visible.
4-cylinder engine: unmatched smoothness and reliable power
For buyers who want a quiet cabin and smooth driving without any jerks, the 4-cylinder engine becomes the first choice. In this, all four pistons work in perfect coordination, due to which the engine's balance remains excellent. This is the reason that even when the car starts, there is hardly any engine noise or vibration inside the cabin and long journeys do not seem tiring.
Whether accelerating on the highway or safely overtaking a heavy vehicle, the 4-cylinder engine inspires driver confidence with its linear power delivery. Even with a fully loaded car and luggage in the boot, there is not much difference in its performance. However, additional cylinders and parts increase the weight and manufacturing cost of the engine. Because of this, vehicles with 4-cylinder engines are a bit expensive and their fuel consumption may also be higher in heavy traffic.
Choose as per your need
Both the engine technologies present in the market are effective in their respective places. If your daily travel is limited to crowded city roads, the budget is fixed and you want more mileage at less expense, then a car with a 3-cylinder engine will prove practical for you. Conversely, if your driving involves long highway trips, frequent family outings and you want a refined driving experience free from engine noise, it might make more sense to spend a little extra budget and get a car with a 4-cylinder engine.
