Performance and exhaust emissions of a spark ignition engine using GSeries and E20 fuels

Öz

In this research, performance and exhaust emissions of a spark ignition (S.I) engine (XU7JP/L3) using gasoline-ethanol blend (E20) and G-Series fuels, of GS1 and GS2, comprised of the mixtures of gasoline, ethanol, biodiesel and diesel were investigated. The results confirm that the power and torque of XU7JP/L3 engine decreases (not significantly) 6.5% and 1.2% respectively for the mixtures of fossil fuel and biofuel blends. In these circumstances the rate of fuel consumption increases by 36%. The results show that the rate of both UHC and CO are low with 8% and 47% reduction but CO2 emission is high. As a conclusion, it is found that the XU7JP/L3 engine has the best performance when it runs on E20 (80 v% gasoline and 20 v% ethanol) and GS1 (10 v% ethanol, 2.5 v% biodiesel, 2.5 v% diesel and 85 v% gasoline). Özet: Bu araştırmada benzin etanol karışımı ve (benzin etanol biyodizel ve dizel karışımı) GS1 ve GS2 gibi G serisi yakıt kullanan kıvılcım ateşlemeli bir motorun (XU7JP/L3) performansı ve egzoz salınımı araştırılmıştır. Sonuçlar XU7JP/L3 motorunun güç ve torkunun fosil yakıt kullanan ve biyo yakıt kullananlarında sırasıyla %6.5 ve %1.2 oranında azaldığını doğrulamaktadır. Bu durumda yakıt karışım oranı %36 ya yükselir. Sonuçlar UHC ve CO oranlarının her ikisinin de sırasıyla %8 ve %47 oranında düşük fakat CO2 salınımının yüksek olduğunu gösterir. Bir sonuç olarak XU7P/L3 motoru E20( hacimsel olarak %80 benzin ve %20 etanol) ve GS1(hacimsel olarak %10 etanol, %2.5 biyodizel, %2.5 dizel ve %85 benzin) ile çalıştırıldığı zaman en iyi performansa sahip olacağı bulunmuştur.
