The paper presents an overview of the latest achievements in gasoline and diesel injection technology. It is already clear that in 20 years' time the internal combustion engine will still be the drive of choicef or the car. Indeed, it still offers a great deal of development potential. Thanks to sophisticated solenoid and piezo-injectors, engineers can no w build smaller engines without sacrificing performance and torque. They refer to this as downsizing. Less engine displacement and fewer cylinders ensure reduced friction losses and therefore greater efficiency. With the same levels of torque, 25 percent less engine displacement cuts fuel consumption by around ten percent. And lower consumption means less CO2. Gasoline and diesel direct injection makes engines even more economical and eco-friendly. Gasoline direct injection, combustion strategies for stratifled-charge operation, GDI injectors, solenoid GDI injectors, piezo GDI injectors, Common Rail Injectors, Common-Rail injectors with piezo actuator, Common-Rail injectors for commercial vehicles, weaknesses of modern high pressure common-rail injectors, multiple injections, Hydrogen Supply Systems, technical requirements for H2 injectors, control range and duration of injection pulse are presented in the paper.
