Relevance of Small Capacity Turbo Petrol Engines in the Indian Market

The vehicle industry’s present tendency has turned to small-capacity turbo petrol engines. Although this technology is not new or groundbreaking in the automotive industry, it is something that the Indian market and customers have only lately been introduced to.

Prices and acceptability, as with any technology, are first difficult to come by; but, as the technology becomes more mainstream, prices become more inexpensive as a result of increased volume. Smaller turbo petrol engines are a good example.

Apart from the most basic hatchbacks, practically every automobile now has at least the option of a strong turbo petrol engine, in addition to a normally aspirated petrol or diesel engine. There are numerous benefits to having a turbo petrol engine in a car, as well as a few drawbacks. Let us delve a little more into this topic to gain a better knowledge.

Petrol engines with turbochargers are required

The need to start investigating turbo petrol engines for even smaller cars has arisen as pollution standards in practically every country get tougher. Various precautions must be taken to maintain absolute minimal tailpipe emissions (hazardous exhaust gases), otherwise the vehicle will be declared unsuitable and, as a result, prohibited to be on the road. As a result, numerous automakers throughout the world have decided to abandon diesel power trains for good.


Others have stated particular timelines within which they expect to stop supplying diesel engines, while others have removed the diesel product entirely from their inventory. Turbocharged petrol engines were introduced to fill the void left by the lack of a punchy and powerful engine. They provide the same kind of low-end torque that makes diesel engines so appealing while emitting less pollution.

People are always looking for more powerful engine options than they currently have, as has always been the case. As a result, turbo petrol engines began to gain popularity as customers discovered that the power and torque ratings were significantly higher than the normally aspirated unit in the same car.

This increased driving enjoyment, allowing customers to enjoy the thrill of a more powerful power plant even in a smaller vehicle. That is why, above the entry-level market, practically all modern cars have the choice of a turbo petrol engine, with diesel engines being phased out.

Turbo-petroleum engine technology

While we won’t go into the technical details of this technology, we will provide you with a basic overview of how turbo petrol engines work. A turbocharger is made up of a turbine and a compressor that are both positioned on the same shaft.

The turbine is directly attached to the exhaust gas manifold and is powered by the mass flow of the engine’s exhaust gases. This rotates the turbine, which in turn rotates the compressor on the engine’s fresh air intake side. The more fresh air we can get into the engine, the more fuel we can mix with it to produce more power, as we all know.

By compressing fresh air, a compressor aids in the fitting of additional air into the cylinder. That’s the general idea. That is broadly how we can extract more power out of a small capacity turbocharged petrol engine.

Because of a turbocharger attached to the engine, we can use a smaller capacity engine by reducing the number of cylinders and hence, reducing the overall weight of the engine. This has its benefits from the efficiency standpoint as the carmakers are always trying to reduce the weight of the cars to improve the power to weight ratio.

Most importantly, we can avoid dealing with harmful emissions as in the case of diesel engines. The OEMs can keep manufacturing products without any problems of the emissions as petrol emissions are easily managed and control with the help of a 3-way catalytic converter.
