Analiza procesa zgorevanja in tvorbe onesnažil pri uporabi piroliznega olja iz odpadnih pnevmatik v dizelskem motorju s skupnim vodom

Moškerc, Jan (author), Katrašnik, Tomaž (mentor)

V zaključni nalogi je predstavljena in preizkušena možnost uporabe piroliznega olja iz odpadnih pnevmatik v sodobnem tlačno polnjenem dizelskem motorju s skupnim vodom. Zaradi nizkega cetanskega števila uporabljenega goriva je neposredna uporaba v dizelskem motorju omejena zgolj na visoke obremenitve. V nalogi je pokazano, da je s spremembo parametrov vbrizgavanja goriva, uvedbo predvbrizga in recirkuliranih izpušnih plinov možno razširiti delovno področje dizelskega motorja ob uporabi 100 % piroliznega olja iz odpadnih pnevmatik. Za potrebe meritev je bila zasnovana merilna veriga namenjena merjenju termodinamskih parametrov in izpustov onesnažil. Rezultati meritev kažejo na to, da lahko sodobni tlačno polnjeni dizelski motor s sistemom skupnega voda učinkovito deluje ob uporabi piroliznega olja iz odpadnih pnevmatik tudi pri srednjih in nizkih obremenitvah pri čemer so izpusti plinskih onesnažil primerljivi, kot pri delovanju z dizelskim gorivom

• Title: Combustion and emission formation analysis of tyre pyrolysis oil in a common rail Diesel engine

Abstract

Thesis represents the possibility of using pyrolysis oil, produced from waste tires, in a modern turbo charged and intercooled automotive diesel engine with a common rail system. Due to the low cetane number of used fuel, direct use in a diesel engine was until now limited only to high loads. The thesis demonstrated that by changing the fuel injection parameters, introducing the pilot injection and recirculated exhaust gases it is possible to extend the working area of the diesel engine using 100% pyrolysis oil, produced from waste tires. For measurement purposes, an experimental rig was designed to measure thermodynamic parameters and emissions. The results of the measurements indicate that a modern turbo charged and intercooled automotive diesel engine with a common rail system can efficiently operate with the use of direct pyrolysis oil produced from waste tires even at medium and low loads, while ensuring gaseous emissions comparable to level emitted with diesel fuel.
