VİTES GEÇİŞLERİNE GÖRE YAKIT TÜKETİMİNİN MODELLENMESİ: VİTES DEĞİŞTİRME STRATEJİLERİNİN YAKIT TÜKETİMİNE ETKİLERİNİN ANALİZİ

Bu çalışmanın amacı, vites geçişlerine göre yakıt tüketimini belirli bir taşıt ve motor özelliklerine bağımlı olmayacak şekilde modellemek ve bu modeli kullanarak vites değiştirme stratejilerinin yakıt tüketimine etkilerini belirlemektir. Vites geçişlerine göre yakıt tüketimini modellemek için öncelikle içten yanmalı motorun moment ve güç karakteristik eğrileri modellenmiştir. Elde edilen motor karakteristikleri ve taşıtın vites oranları kullanılarak her vites oranı için taşıt hızını, ihtiyaç duyulan çeki kuvvetini ve motorun özgül yakıt tüketimini elde eden alt modeller geliştirilmiştir. Bu alt modelin çıkışları ile vites geçişlerine göre yakıt tüketimi modellenmiştir. Geliştirilen model ile geometrik ve progresif diziye dayalı iki farklı vites değiştirme stratejisinin yakıt tüketimine etkileri belirlenmiştir. Bunun için bu iki metot kullanılarak vites oranları hesaplanmış ve bu vites oranlarına göre yakıt tüketim eğrileri elde edilmiştir. Her iki stratejiye ait yakıt tüketim eğrilerinin birine göre farklılıkların nedeni, çeki diyagramları ile araştırılmıştır. Böylece geliştirilen modelleme metodu, geometri dizi ile progresif dizinin yakıt tüketimine etkilerinin çeki diyagramına dayalı bir şekilde belirlenmesini sağlamıştır.
