Starter selection is a critical decision in diesel engine design. The starter performance curves are generally accepted in the industry, with current on the horizontal axis and power, volts, speed and starter torque on the vertical axis. In this way, it is not possible to compare the starter performance curves with the engine friction force curve. In this study, a method has been developed for the selection of suitable starter for diesel engines. With the developed method, the starter performance curve is converted and the engine friction curve is shown on the same graph. With this method, it can be easily understood whether the starter is suitable for a diesel engine. In addition, possible problems that may be encountered during cold start-up can be foreseen. The developed method uses actual performance measurements given by the starter manufacturer. On the engine side, if there is an existing engine, engine friction test results are used. If the engine is in the design phase, the friction force results obtained by simulation are used.

Marş motoru seçimi, dizel motor tasarımında kritik bir karardır. Marş motoru performans eğrileri endüstride genel kabul gören şekli ile yatay eksende akım, dikey eksende ise güç, volt, hız ve marş motoru torku olacak şekildedir. Bu şekilde marş motoru performans eğrilerinin motor sürtünme kuvveti eğrisi ile karşılaştırılması mümkün olmamaktadır. Bu çalışmada, dizel motorlar için uygun marş motoru seçimine yönelik bir yöntem geliştirilmiştir. Geliştirilen yöntem ile marş motoru performans eğrisi dönüştürülerek, motor sürtünme eğrisi aynı grafik üzerinde gösterilmektedir. Bu yöntem ile marş motorunun dizel motora uygun olup olmadığı kolaylıkla anlaşılabilmektedir. Ayrıca soğuk çalıştırma sırasında karşılaşılabilecek olası problemler öngörülebilmektedir. Geliştirilen yöntem, marş motoru üreticisi tarafından verilen gerçek performans ölçümlerini kullanır. Motor tarafında ise mevcut bir motor varsa motor sürtünme testi sonuçları kullanılır. Eğer motor tasarım aşamasında ise simülasyon ile elde edilen sürtünme kuvveti sonuçları kullanılır.
