چکیده
Yanma odasından dışarıya transfer edilen ısı miktarı yanma verimini direkt etkilemektedir. Isı miktarının artması azaltmaktadır. Motorlarda termal kaplama yöntemleri ile azaltılarak verimi artmaktadır. Fakat odasının tamamının malzeme kaplanması buji ateşlemeli motorlarda vuruntu temayülünün artmasına ve emisyon değerlerinin kötüleşmesine neden olmaktadır. Vuruntu azaltılmasında en etkiyi yöntemlerinden biri de su-buhar enjeksiyon yöntemidir. Su yöntemi motor performans parametrelerinde kötüleşme olmadan değerleri kayda değer oranlarda azaltılabilmektedir. Çalışmada, arttırmak için piston üst yüzeyi rezervi yüksek MgOZrO2 seramik kısmi kaplanmıştır. Kaplamalı motora, anlık yakıt tüketiminin %10, %20 %30 kütlesel oranlarında emme manifolduna su püskürtülmüştür. İki yöntem aynı anda kullanılarak parametreleri egzoz emisyonlarında iyileşmeler elde edilmiştir. TBL pistonlu motorda güç, tork, özgül sarfiyatı, efektif verim HC emisyonları iyileşirken NOx Emme yapılması durumunda ise artan azalmaktadır. % 20 püskürtme oranında torku güçte 4,1, sarfiyatında, %3,8 verimde %3,9 saptanmıştır. standart verilerine göre azalma Ayrıca 33’e varan azalmalar

Effect of electrode erosion on the required ignition voltage of spark plug in CNG spark ignition engine
In this article, the electrode erosion and the gap growth of spark plugs were measured on of a CNG fueled engine after durability tests. Then, the required ignition voltage and the spark quality were investigated by a spark plug test rig. Considering results of measurements, the gap growth increased as the running time increased. Thus, the gap growth of spark plugs with 200 and 280 hours runnin...

متن کاملEffect of Injection Characteristics on Emissions and Combustion of a Gasoline Fuelled Partially-premixed Compression Ignition Engine
Conventional compression ignition (CI) engines are known for their high thermal efficiency compared to spark ignited (SI) engines. Gasoline because of its higher ignition delay has much lower soot emission in comparison with diesel fuel. Using double injection strategy reduces the maximum heat release rate that leads to NOx emission reduction. In this paper, a numerical study of a gasoline fuel...
