The automotive industry has been witnessing a robust growth all across the globe, which can primarily be attributed to the rapid economic growth in developing countries, rising disposable income of people, and emergence of electric vehicles in the market. Because of all these factors, the production capacity of automobile industries has risen significantly. During the time period, 2005–2019, approximately 91.3 million motor vehicles sold worldwide, and the global automotive industry is predicted to generate a revenue of nearly $9 trillion by 2030. Moreover, about 92 million motor vehicles were produced around the world.

Now, it is fairly obvious that with the rising demand for automobiles, the requirement for different automobile components and supporting infrastructure will increase as well. Owing to this, the demand for automotive fuel injection systems is growing swiftly. The engine of an automobile needs to be provided with just the right amount of fuel/air mixture for running efficiently and smoothly. Conventionally, this mixture was taken care of by the carburettor; however, a single carburettor was unable to supply four-cylinder engine with precisely the same amount of fuel/air mixture, which is why engines are now being equipped with fuel injection systems. These engines are more efficient, powerful, and economical than the carburetted ones.

Ascribed to these factors, the automotive fuel injection system market is expected to advance at a substantial pace in the coming years. among heavy commercial vehicles, light commercial vehicles (LCV), and passenger cars, the largest demand for fuel injection systems in the past was created for passenger cars. This is due to the growing disposable income of people and swift urbanizations. Other than this, the requirement for these systems for light commercial vehicles is also predicted to rise considerably in the coming years, on account of low cost of LCVs and their high adoption for logistics supply chains, particularly in emerging economies.

The different components of a fuel injection system are fuel pressure regulator, fuel injector, fuel pump, and engine control unit (ECU). These systems are of two types in terms of fuel, namely diesel and gasoline. The demand for diesel fuel injection systems is expected to be higher in the coming years, which is attributed to the lesser greenhouse gas emissions from diesel engines and their high fuel efficiency. In terms of technology, there are three types of fuel injection systems— gasoline direct injection, diesel direct injection, and gasoline port injection.

Diesel direct injection was the most in demand in the past, as these engines are currently the most efficient combustion engines and have the highest degree of thermal efficiency. The Asia-Pacific region is projected to emerge as the largest automotive fuel injection system market in the coming years. This is because of the high vehicle production and stringent regulations regarding emissions in the region. The enhanced economy and living standards in India and China have led to the increased sales volume of vehicles in the region.

Hence, the demand for fuel injection systems is growing due to the surging sales of vehicles.
