As a core component of the engine's fuel supply system, the fuel injector directly affects the engine's power output, fuel economy, and exhaust emissions. It plays a crucial role in the automotive industry, and its performance stability is essential for the long-term operation of vehicles.
Bosch is a major manufacturer of high-pressure diesel injection systems, and its common rail injection system technology has undergone continuous iteration. In 1997, Bosch first launched a common rail injection system for passenger cars. Its injection pressure increased from 1350 bar in the first generation to 2200 bar in the fourth generation.
In the commercial vehicle sector, for example, the VG1034080002 injector is adapted to the Sinotruk D12 series diesel engine and is used in tractor trucks, cargo trucks, and other models. This model uses a multi-hole nozzle design with a rated injection pressure of 1800 bar. Under high-intensity operating conditions such as long-distance transportation, it is claimed to improve fuel economy by 3%-5% and help reduce particulate matter and nitrogen oxide emissions.
In the passenger car performance field, new technologies are also continuously being applied. For example, the performance package for the 2024 Ford Mustang Dark Horse includes upgraded fuel injectors.
