Market Growth Factors
1. Technological Advancements in Diesel Engines
The market for diesel common rail injection systems is greatly impacted by ongoing technological advancements with the objective of increasing engine efficiency and performance. The development of electronically controlled, low-pressure common rail systems has been launched, serving small diesel engines in off-highway vehicles. The developments facilitate accurate fuel delivery, leading to efficient combustion and lower emissions. For example, in September 2024, PHINIA Inc. has launched an electronically controlled low-pressure common rail injection system for small diesel engines in off-highway applications with Kohler Engines. Such innovations are very important in complying with strict emission standards without sacrificing diesel’s high torque and fuel efficiency.
2. Regulatory Impact and Emission Standards
Tough emission standards globally are forcing manufacturers to implement sophisticated diesel injection technologies. Governments in Europe, Asia-Pacific, and North America are implementing tougher emissions standards for reduction of nitrogen oxides (NOx) and particulate matter emissions. For instance, in December 2023, laws were passed in Colorado to restrict emissions from stationary engines in order to meet the 2025 NOx reduction goal. These laws require common rail injection systems that can accurately control fuel injection to decrease harmful emissions. Meeting such standards is pushing companies to adopt CRDI systems, which provide greater fuel efficiency and less emission than traditional diesel engines.
3. Rising Demand in Commercial Vehicles and Construction Equipment
The increasing commercial vehicles market is a key motivator for the diesel common rail injection system market. Diesel engines with common rail injection systems find extensive applications in heavy-duty trucks, buses, farm equipment, and construction machinery because of their power, fuel efficiency, and toughness. For example, the size of the commercial vehicles market globally was USD 803.6 billion in 2023 and is likely to grow to USD 1,114.2 billion by 2032, as per IMARC. Such increased production of commercial vehicles has a direct impact on the demand for effective diesel injection systems since producers endeavor to improve vehicle performance and comply with emission regulations.
