Fuel Pumps
Pumps which are used for the injection of fuels into diesel engines are the technically most demanding members in the family of pressure generators. The provision of fuels under high pressure to common-rail injectors and fuel injection valves calls for robust dimensioning of the pump drives, the determination of optimum clearance in the pump element and the application-oriented selection of high-strength steels with special heat treatment processes. In addition, our pumps are characterized by know-how developed over decades in terms of helices in the case of conventional pump-line-nozzle systems (PLN), component coatings, sealing elements or valve engineering. The results obtained combining hydraulic simulation, static finite elements modeling and nonlinear finite elements analysis already provides clear-cut data in the preliminary design phase as regards delivery rates and efficiency levels, component loads or lifetimes as well as the minimum surface pressures necessary for sealing.

Cooled Injection System CIS
GERSTEL Cooled Injection System - internationally the most frequently used PTV-type universal inlet, with patented septumless sampling head.
Gas chromatographic analysis is now more versatile, reproducible and has lower detection limits than ever before, thanks to temperature programmed sample injection using GERSTEL Cooled Injection System.
The GERSTEL CIS provides two essential system-functions:
- Universal injection system for all injection techniques: split, splitless, on-column and large-volume up to 1000 µl.
- Cryotrap enrichment system in combination with sample preparation systems, for example, the GERSTEL ThermalDesorption System TDS, the Thermal Desorption Unit TDU or the GERSTEL MultiPurpose Sampler MPS.
The high temeprature version CIS 6 enables automated pyrolysis of liquid polymer suspensions in combination with the MPS autosampler. The CIS is easily and conveniently controlled from the GERSTEL MAESTRO Software - stand alone or through the Agilent Technologies ChemStation software. One method and one sequence table controls the complete system including GC/MS.

Fuel injection valves
As components of pump-line-nozzle injection systems, conventional fuel injection valves ensure that when a defined opening pressure of the fuel supplied by the injection pump is exceeded, the fuel is injected very quickly in a uniform fine atomization. Here not only a precise begin of injection is very important but also fast closing at the end of the injection process. Proper static and dynamic design of the injection hydraulics prevents so-called needle shocks. This reliably prevents from even very minor unintended post-injection with after-dribbling effects, something that is necessary to ensure smokeless engine operation.
