The Direct Injection has become the foremost choice of automakers for petrol powered models.
The direction-injection petrol engine also describes as a gasoline-direct injection (GDI) or simply the DI, the technology has revolutionized the petrol engine in many ways.
It offers great benefits and has significant advantages over the traditional indirect injection petrol engines. The notable benefits include better fuel efficiency and low carbon emissions.
Advantages of Direct Injection
The DI technology has reshaped the traditional petrol engine pattern; the DI has not only increased fuel efficiency but also enhanced engine performance. However, the fuel injection is a fundamental benefit of this technology. It is important to mention that the traditional indirect petrol engine technology allowed the mixture of air and fuel before the combustion chamber and then the mixture was injected for the combustion process to ignite.
On the contrary, the latest direct injection technology has enabled the petrol engine to directly inject the fuel in the combustion chamber of the cylinder with the help of the specifically designed piston. The combustion process ignites with the less fuel with the help of DI technology. It has helped to overcome the fuel losses and resulted of better fuel efficiency.The efficient and fast combustion process means the less gasses exhausts, thus, the new petrol-powered vehicles deliver better fuel efficiency as well as low carbon emission figures.
Significant Developments
The engineers had developed a couple of other important technologies with the direct injection for petrol engines. The other revolutionary technologies include the turbocharging, variable valve timing, cylinder deactivation and exhaust gas recirculation. All these technologies work simultaneously in a modern petrol engine and help to achieve more power, vectoring torque, better fuel efficiency and low carbon emissions figures.
The new petrol car models are being developed with the direct injection technology. It has made the petrol engine perfect choice for millions of motorists across the globe. The direct injection petrol engine technology is expensive and it requires sophisticated technical expertise because of its complexity. The race has already begun to make it viable and affordable option for all petrol fuel models.
