 Piezo direct injection – taking fuel economy to new levels

Since 2006 the trend setting piezo technology has also been implemented with gasoline engines – particularly for higher displacement engines. By using piezo direct injection we facilitate a stable combustion in a stratified lean operation, thus achieving the greatest possible fuel savings in an extended engine operating range. Compared to conventional port injection, this can result in fuel consumption reductions of up to 20%.

  In addition to our injector know-how, our comprehensive system solution portfolio also includes efficient high pressure pumps, generating fuel pressure of up to 20 MPa (200 bar), and intelligent engine management control units. The modular and scalable engine management platform, based on our EMS 3, allows us to meet challenging quality targets despite ever shorter development cycles and the constantly growing number of variants. Furthermore, we also offer injection systems for alternative fuels such as compressed natural gas, liquefied petroleum gas and ethanol, which can make a contribution to reducing global CO2 emissions.

Solenoid direct injection – increased torque at lower engine speeds

 In turbocharged, homogeneous combustion gasoline engines, in combination with variable valve timing, our solenoid direct injection technology offers significant fuel saving potential, a reduction in emissions and an increase in lower engine speed torque compared to port injection. Our DI XL3 solenoid injector provides enhanced linearity due to very fast opening and closing times and multi-stream spray geometry enables optimal adaptation to all engine-specific requirements.

  Port injection – proven technology

 Particularly in the high-volume segments port injection continues to dominate the market because of its attractive cost benefit ratio. Specifically for this type of engine, we have developed the DEKA VII injectors – with reduced weight, extended range of operations and improved performance.

. Extremely fine atomization improves the combustion process, thereby reducing emissions of the engine. Adaptability to different applications is a key property of the DEKA VII family: all three body lengths can be combined with any nozzle length option and retain identical characteristics. Furthermore, a wide range of spray forms can also be adjusted to suit different intake manifold geometries.
