“…Compared to engines without that feature benefits such as a lower exhaust emission or a higher output power at a given fuel consumption are achievable [1,2]. However, higher requirements with respect to injection parameters (e.g., injection pulse width, fuel quantity, multiple injections per combustion cycle) demand an injection system with a high reliability.…”

For 'on board' diagnosis purposes of the injected fuel quantity, ceramic flow sensor chips with a diameter of 2.2 mm were integrated into finished Common Rail injection nozzles of the valve covered orifice (VCO) or mini-sac hole (MSH) class. The influence of this integration step on the hydraulic performance of the high-precision injector nozzles which led to an optimized process flow with a minimized disturbance of the fluidic properties was investigated. Electron-discharge machining and electron-beam welding technology proved to be the key technologies for this integration process, providing a reliable solution for injection pressures ranging up to 135 MPa (1350 bar). With a highpressure hydraulic test bench the decrease in the injected fuel quantity as a function of welding parameters was determined for both nozzle classes. The geometrical distortion of the nozzle was mainly attributed to a radial bending of the nozzle tip and is dominated by the heat concentration during the welding process. In comparison, the integration of the ceramic sensor chip causes lower distortion values. By reducing the thermal energy input during welding a negligible influence of the complete integration process with respect to the hydraulic performance of original orifices is demonstrated at MSH injection nozzles.

“…In order to follow the emissions regulations, the diesel engine industry has undergone a great technological development during the last few years. Various strategies have been proposed to reduce the amount of emissions exhausted from the diesel engines, especially NO x and soot [1][2][3][4]. One of the most efficient and lowest-cost strategies is the use of artificial intelligence (AI) methods in engineering management systems (EMS) [5].…”

The objective of this work was to investigate the effects of injection conditions and swirl on D.I. diesel combustion using a transparent engine system. The test engine is equipped with a common rail injection system to control injection conditions and to obtain split injection characteristics. A combustion analysis and steady flow test were conducted to measure the heat release rate due to cylinder pressure and the swirl ratio. In addition, spray and diffusion flame images were obtained using a high speed camera. The LII & LIS methods were also used to obtain 2-D soot and droplet distributions. High injection pressure was found to shorten ignition delay, as well as to enhance peak pressure. The results also revealed that the heat release rate in the premixed combustion region was markedly reduced through the use of pilot injection, while the soot distribution and the heat release rate in the diffusion combustion region were increased. The swirl effect was found to shorten ignition delay at certain injection timings, and to enhance the heat release rate in all experimental conditions.
