Effect of Fuel Enrichment with Hydrogen on Engine Performance and Emission Characteristics of Diesel Engine

Öz

Increase in air pollution and seeking to improve engine performance has increased the need for additional fuels such as hydrogen.  In this study, the effects of hydrogen addition on biodiesel fuel produced from waste frying oil on the operating characteristics of an ignition engine have been experimentally investigated. Hydrogen is introduced into the inlet air at a certain flow rate. Performance and emission values of the diesel engine were examined. Pure diesel fuel is selected as the reference fuel to compare the operational characteristics of the engine with respect to various fuels. As a result, it has been observed that the hydrogen addition increases the engine performance. When hydrogen gas is supplied to engine cylinders, CO and CO2 emissions are reduced and NOx emissions are increased.

Hidrojen ile Yakıt Zenginleştirmenin Dizel Motorun Motor Performansı ve Emisyon Özelliklerine Etkisi

Öz

Hava kirliliğinin giderek artışı ve motor performansı arttırmaya yönelik arayışlar hidrojen gibi ek yakıtlara olan ihtiyacı artırmıştır. Bu çalışmada, bir sıkıştırma ateşlemeli motorun çalışma karakteristikleri üzerine atık kızartma yağından üretilen biyodizel yakıtına (AKY) hidrojen ilavesinin etkileri deneysel olarak incelenmiştir. Hidrojen, giriş havasına belli bir debide verilmiştir. Yapılan testte dizel motorunun performans ve emisyon değerleri incelenmiştir. Katkısız dizel yakıt, motorun çeşitli yakıtlara göre operasyonel özelliklerini karşılaştırmak için referans yakıt olarak seçilmiştir. Sonuç olarak hidrojen ilavesinin motor performansını artırdığını gözlemlenmiştir. Hidrojen gazı motor silindirlerine verildiğinde CO ve CO2 emisyonları azalmış ve NOx emisyonları ise artmıştır.
