20.500.12556/DKUM-26186 Investigation into the effect of different fuels on ignition delay of M-type diesel combustion process An ignition delay is a very complex process which depends on a great number of parameters. In practice, definition of the ignition delay is based on the use of correlation expressions. However, the correlation expressions have very often limited application field. This paper presents a new correlation which has been developed during the research project on the direct injection M-type diesel engine using both the diesel and biodiesel fuel, as well as different values of a static injection timing. A dynamic start of injection, as well as the ignition delay, is defined in two ways. The first approach is based on measurement of a needle lift, while the second is based on measurement of a fuel pressure before the injector. The latter approach requires calculation of pressure signals delay through the fuel injection system and the variation of a static advance injection angle changing. The start of a combustion and the end of the ignition delay is defined on the basis of measurements of an in-cylinder pressure and its point of separation from a skip-fire pressure trace. The developed correlation gives better prediction of the ignition delay definition for the M-type direct injection diesel engine in the case of diesel and biodiesel fuel use when compared with the classic expression by the other authors available in the literature. ignition delay diesel engine M-type biodiesel zakasnitev vžiga dizelski motor tip M biodizel biodiesel true false true Angleški jezik Slovenski jezik Znanstveno delo 2012-05-31 12:07:55 2012-05-31 12:07:55 2022-04-15 13:22:17 2024-01-03 03:21:49 2008 0 0 str. 103-114 št. 1 Letn. 12 2008 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0354-9836 621.43.013.43 21135621 12315926 10.2298/TSCI0801103B 0354-9836 URN:SI:UM:DK:LGQRNBHZ Thermal_Science_2008_Bibic_et_al._Investigation_into_the_effect_of_different_fuels_on_ignition_delay_of_M-type_diesel_combustion_process.pdf Thermal_Science_2008_Bibic_et_al._Investigation_into_the_effect_of_different_fuels_on_ignition_delay_of_M-type_diesel_combustion_process.pdf 1 21A9E9DA52A229DF3FE215F136B2B52B 38467be62492e8c8af5115ba9ced67f4f07746e43f7d0a18cd075c3ac159810b 607aaa4a-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/12b6115d-c16f-426b-b529-4ade4c482439 https://dk.um.si/Dokument.php?lang=slv&id=113844 http://www.doiserbia.nb.rs/Article.aspx?ID=0354-98360801103B 1 https://dk.um.si/Dokument.php?lang=slv&id=35130 Fakulteta za strojništvo 0 0 0
