Düşük güçte bir motor test düzeneği kurulumu ve örnek bir uygulama gerçekleştirilmesi

İçten yanmalı motorların test edilmesi işleminde genellikle ithalat yoluyla temin edilen, oldukça yüksek maliyetlimotor test dinamometreleri kullanılmaktadır. Bu çalışmanın amacı, oldukça yüksek maliyetli olan içten yanmalımotor test dinamometreleri yerine, tek silindirli dizel motorlu bir jeneratörün motor test düzeneğinedönüştürülmesi ile düşük maliyetli bir içten yanmalı motor test düzeneği elde etmektir. Elde edilen düzenekteviskozitesi toluen ile iyileştirilmiş olan fuel-oil kullanılarak motor performansına etkileri incelenmiştir. Bu çalışmakapsamında 10 HP güce ve 3000 d/d sabit devire sahip dizel motorlu jeneratör kullanılmıştır. Dizel motorunyüklenmesi işlemi jeneratöre alıcı bağlanması ile gerçekleştirilmiştir. Motorun gücü ve her bir krank mili açısı içinsilindir içi basıncı, yakıt hattı basıncı anlık olarak gözlenmiş ve kaydedilmiştir. Dizel ve dizel+fuel-oil karışımlarıkullanılarak gerçekleştirilen deneylerde, fuel-oil katkısı ile silindir içi basınç değerinin düştüğü, yakıt tüketimininve egzoz gazı sıcaklığının arttığı görülmüştür.

Designing a low power motor test assembly and performing a sample application

In the process of testing the internal combustion engines, high-cost engine test dynamometers are generally used. The aim of this study is to obtain a low-cost internal combustion engine tester by converting a single-cylinder diesel engine generator into a motor tester, rather than a high-cost internal combustion engine test dynamometer. Engine performance effects were investigated by using fuel-oil with viscosity toluene. Within the scope of this study, diesel powered generator with 10 HP power and 3000 1/min constant speed is used. The loading of the diesel engine was carried out by connecting the receiver to the generator. The in-cylinder pressure for the engine power and the crankshaft angle was instantaneously monitored and recorded at the fuel line pressure. In experiments carried out using diesel and diesel + fuel-oil mixtures, with the addition of fuel-oil, it was seen that the pressure in the cylinder decreased and fuel consumption and exhaust gas temperature increased.
