  1. 1. Filtering Pressure Oscillations in a Common Rail Pressure Signal with IIR Notch Filters for Injected Fuel Amount Estimation

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Marcus Akkila; Denis Ramsden; [2023]
    Nyckelord :DSP; Water hammer effect; IIR; Common-rail; Injected fuel amount estimation; Notch filter; Water hammer effect; IIR; Digital signalbehandling; Injektionsmängd; Common-rail; bandstoppfilter;

    Sammanfattning : This project concerns an inline six-cylinder (I6) diesel truck engine equipped with common-rail injection system. It has been done at the Swedish truck manufacturer Scania CV AB. The main focus is digital signal processing of the rail pressure sensor signal from the injection system. LÄS MER

  3. 2. Pressurizing of high-pressure fuel system forsingle cylinder test cell

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Gustaf Glaad; [2019]
    Nyckelord :Alternative fuels; Ultra high-pressure fuel system; Common rail direct injection fuel system; Diesel-like fuels; Compression ignited fuels;

    Sammanfattning : This master thesis covers the development of a high-pressure fuel system for compression ignitedfuels such as diesel and diesel-like fuels that will be deployed into a single cylinder test cell at AVLMTC Södertälje, Sweden. The test cell is used by AVL to conduct research and testing of new fuelsfor their customers and this new fuel system will widen the span of fuels able to be tested by theequipment. LÄS MER

  4. 3. Modelling of high-pressure fuel system for controller development

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Eric Pettersson; [2019]
    Nyckelord :Common-Rail Direct Injection; fuel system; water hammer; pressure oscillations; physical modelling; state-space representation;

    Sammanfattning : This master thesis treats the modelling of a common-rail direct fuel injection system where pressure generation is decoupled from the injection process. It has been shown that the fuel pressure plays a vital role for the general performance of the engine, affecting both emissions and efficiency, and it is carefully regulated to achieve optimal performance at different operating points.

  5. 4. Fuel Pressure Modelling in a Common-Rail Direct Injection System

    Master-uppsats, Fordonssystem

    Författare :Kurt Källkvist; [2011]
    Nyckelord :diesel; pressure; modelling; injection; common-rail; fuel; diesel; insprutning; tryck; modellering; common-rail; bränsle;

    Sammanfattning : The fuel pressure is one of the central control variables of a modern common-rail injection system. It influences the generation of nitrous oxide and particulate matter emissions, the brake specific fuel consumption of the engine and the power consumption of the fuel pump. LÄS MER
