Siemens is a technology company operating in four core sectors: industry, energy, healthcare and smart infrastructure. With a history of more than 170 years, Siemens is present in over 200 countries and employs around 293,000 employees worldwide. Siemens has 289 production and manufacturing sites in different regions and markets. Some of the largest plants are located in Germany, where the company's headquarters are located in Berlin, Munich and Erlangen. Siemens is characterized by innovation, quality and a commitment to sustainable development and the digitalization of industry and infrastructure.

Siemens is a leading company in the development and manufacture of injection systems for internal combustion engines. Injection systems are devices that regulate the quantity and timing of fuel introduction into the engine cylinder, which directly influences the performance, efficiency and emissions of the vehicle. Siemens offers different types of injection systems, adapted to the needs and characteristics of each engine and vehicle. Some of the most notable Siemens injection systems are:

- Gasoline Direct Injection (GDI): This system allows fuel to be injected directly into the combustion chamber, improving performance and reducing fuel consumption and emissions. The Siemens GDI system features piezoelectric injectors that enable precise control of fuel flow and pressure, as well as rapid response to variations in engine load.

- Indirect fuel injection (PFI): This system injects fuel into the intake manifold before the inlet valve. Siemens' PFI system uses electromagnetic injectors that offer good value for money and easy integration into the engine.

- Common rail diesel injection (CRDI): This system uses a high-pressure pump that feeds a common rail that distributes the fuel to the injectors. The Siemens CRDI system uses piezoelectric or solenoid injectors that allow multiple and precise injection of fuel, which optimizes combustion and reduces noise, consumption and emissions.

- Pump-injector injection (PDE): This system consists of one pump-injector per cylinder, which generates the pressure required to inject the fuel directly into the combustion chamber. The Siemens PDE system uses electromagnetic or piezoelectric injectors that guarantee high pressure and precise control of injection time and quantity.
