The comparison of combustion, engine performance and emission characteristics of ethanol, methanol, fusel oil, butanol, isopropanol and naphtha with n-heptane blends on HCCI engine

Isopropanol dehydration reaction rate kinetics measurement using H2O time histories

“…14,15 Isopropanol has, however, been studied previously in both spark ignition and HCCI engines to examine its potential as a gasoline additive. [16][17][18][19][20][21] Results of these studies show significantly reduced CO and HC emissions, 16 and virtually zero NO emissions in HCCI engines, being noted as more suitable for HCCI combustion in its knock prevention. 20 Isopropanol has also been studied in diffusion flames 22,23 and more recently in both premixed and nonpremixed flames using more advanced speciation techniques.…”

Homojen Dolgulu Sıkıştırma ile Ateşlemeli Bir Motorda N-Heptan-Tetrahidrofuran Karışımlarının Yanma, Performans Ve Emisyonlara Etkisi

“…Günümüzde araştırmacılar elektrikli araç teknolojisi ve alternatif yanma modelleri üzerine birçok çalışma yapmaktadır [11][12][13][14][15]. Düşük sıcaklık yanmasına sahip homojen dolgulu sıkıştırma ile ateşlemeli (HCCI) motorlar son yıllarda araştırmacıların oldukça ilgisini çeken yeni bir yanma modelidir [16][17][18][19]. HCCI motorların en önemli özelliği hava yakıt karışımının SI motorlarda olduğu gibi önceden hazırlanması ve yanmanın CI motorlarda olduğu gibi sıkıştırma zamanı sonunda basınç ve sıcaklığın etkisi ile kendiliğinden meydana gelmesidir [20][21][22].…”

Research of Energy and Ecological Indicators of a Compression Ignition Engine Fuelled with Diesel, Biodiesel (RME-Based) and Isopropanol Fuel Blends

“…When using 25% isopropanol in petrol blends with combustion control, there is a direct relationship between octane number and combustion parameters of isopropanol. Start of combustion (SOC) is delayed by increasing isopropanol content in the blend because isopropanol is more resistant to jerky engine operation [39]. By reducing spark time in a petrol engine, isopropanol-gasoline blends (with isopropanol content up to 30%) had lower NO x emissions than those found at the initial spark time [40].…”
