It is necessary to meet increasingly stringent emission standards of IC engines, reducing the emission values. While improving engine parameters and combustion chamber geometries can reduce emissions, also the research continues for alternative fuels. Diesel production from waste cooking oils has advantages in terms of recycling, environment, and cost. Waste cooking oils can be used as fuel with minor modifications. Waste cooking oil-based biodiesel can be used in neat form or blend with diesel. In this way, there is no need to make any modifications to the existing diesel engines. In this study, diesel was blended with biodiesel at 20% (B20) and it was used as fuel in a CI engine. The performance and emission values of this blend were compared according to neat diesel fuel. As a result of the experimental and CFD simulation studies, it was observed that the use of the B20 fuel blend reduced CO emissions by 10.5%, NOX emissions by 2.3%, and soot emissions by 10.2% according to neat diesel usage. In addition, the maximum pressure inside the cylinder has decreased by 2.5%.

Sıkıştırma Ateşlemeli Bir Motorda Kullanılan Atık Yemek Yağı Biyodizel Karışımının Deneysel ve Sayısal Analizi

Öz

İçten yanmalı motorların emisyon değerlerinin azaltılması, gittikçe katılaşan standartların karşılanması için gereklidir. Motor parametreleri ve yanma odası geometrilerinin iyileştirilmesi emisyonları azaltabileceği gibi, alternatif yakıt arayışları da sürmektedir. Atık yemek yağlarından dizel üretimi, hem geri dönüşüm ve çevre duyarlılığı bakımından hem de maliyet bakımından avantajları olmaktadır. Atık yemek yağlar, küçük modifikasyonlarla, yakıt olarak kullanılabilecek duruma gelmektedir. Üretilen biyodizel saf halde kullanılabileceği gibi, dizel ile karıştırılarak kullanılabilmektedir. Bu şekilde, mevcut kullanılan dizel motorlarda herhangi bir modifikasyon yapmaya gerek kalmamaktadır. Bu çalışmada, kütlesel %20 oranında biyodizel, dizel ile karıştırılarak, yakıt olarak sıkıştırma ateşlemeli bir motorda kullanılmıştır ve saf dizel yakıt kullanıma göre performans ve emisyon değerleri karşılaştırılmıştır. Deneysel ve CFD simülasyon çalışmaları sonucunda, B20 yakıt karışımı kullanımıyla, CO emisyonlarında %10.5, NOX emisyonlarında %2.3 ve is emisyonlarında %10.2 oranında azalma gözlemlenmiştir. Ayrıca silindir içi maksimum basınç, %2.5 oranında azalmıştır.
