“…to a higher percentage of fuel being mixed with air, which results in less smoke and more significant NOx emissions [6]. Du et al [7] and Lu et al [8] the effects of gasoline/diesel blends on the combustion process and on the emissions of a multi-cylinder light duty diesel engine. Their results indicate that an increasing volume fraction of gasoline in the blend can reduce smoke emissions at higher operating loads through an increase in charge premixing due to the longer ignition delay and to the higher fuel volatility.…”

The organizing of combustion process in the advanced internal combustion engine is developing toward unified combustion mode of gasoline-engine-like premixed gas formation and diesel-engine-like compression ignition. Gasoline/diesel blended fuel has received extensive attention for its suitability for this combustion characteristic, owing to its relatively poor ignitability and high volatility. In order to more comprehensively evaluate the application of the blended fuel on this combustion mode, an experiment was conducted to characterize the particle size distribution and total number concentration of exhaust particles from the gasoline/diesel blended fuel. The premixed combustion characteristics and relatively high hydrocarbon emission were confirmed first and their effects on the particle size distribution were determined subsequently. Combustion control parameters such as exhaust gas recirculation and injection pressure were also taken into account. Results indicated that gasoline/diesel blended fuel had significant effect on the particle size distribution due to the higher premixed combustion ratio and more unburned hydrocarbon emission. Under high load condition, as the proportion of gasoline blending increased, the accumulation mode particle decreased while the nucleation mode particle and total particle number increased significantly. The geometric mean diameter of exhaust particle decreased with the addition of gasoline. The effect of exhaust gas recirculation and injection pressure on the particle size distribution of gasoline/diesel blended fuel was less than that of pure diesel. That meant the gasoline/diesel blends were beneficial for carbonaceous particle (>22 nm) reduction. However, the nucleation mode as well as total particle number were still higher for gasoline/diesel blends than that for pure diesel.

“…Ancak taşıt sayısındaki artış ile birlikte emisyonlardaki toplam artış engellenemez boyutlara ulaştığı, kabullenilmesi gereken üzücü ve tedirgin edici bir gerçektir [1][2][3]. Otomotiv endüstrisi, taşıt performansından ödün vermeksizin emisyonları ve fosil yakıt bağımlılığını azaltmaya yönelik önemli araştırmalara odaklanmaktadır [3][4][5][6]. Özellikle günümüzde emisyonları azaltmak için seçici katalitik indirgeme (SCR), dizel oksidasyon katalizörü, katkılı yakıtlar, otomatik stop-start gibi teknolojiler hem motor hem de yakıt ve taşıt teknolojisinde oldukça ilerlemeler kaydedildiği bilinmektedir [3, [7][8][9].…”

Hibrit elektrikli taşıtlarda elektrik motoru ve içten yanmalı motor (İYM) olmak üzere farklı karakteristiklere sahip iki farklı tahrik sistemi bulunmaktadır. Bu iki tahrik sistemi farklı taşıt karakteristiklerine uygun olarak seri, paralel veya seri paralel şekilde düzenlenebilmektedir. Günümüzde yaygın olarak hem seri hem de paralel tahrik sistemlerinin avantajlarını en uygun düzeyde birleştiren seri-paralel tahrik sistemi kullanılmaktadır. Seri paralel tahrik sisteminde elektrik motoru ve İYM'nin güç aktarım stratejisinin düzenlenmesi için güç dağıtıcı (power split) mekanizması kullanılmaktadır. Yapılan bu çalışmada belirli hız aralığında sabit tork elde edilebilen bir İYM'nin güç dağıtıcı mekanizmasına adapte edilmesiyle güç aktarım stratejisinin bu hız aralığına bağlı olarak incelenmesi hedeflenmiştir. Güç dağıtıcı mekanizmasında yörünge/güneş dişli oranı sabit tutulmuştur. Bununla birlikte taşıtın için farklı hız ve güç taleplerinde motojeneratörlerin motor/jeneratör durumları ile batarya sisteminin şarj/deşarj durumları İYM'nin farklı hızları için hesaplanmış ve tartışılmıştır. Sonuç olarak güç dağıtıcı mekanizması için sabit torkta İYM hızının etkileri ve İYM hızını etkileyen parametreler belirlenmiştir.
