In this study, the cycle analysis of two stroke reverse-uniflow, carburettor, spark ignition engine was determined by using a theoretical mathematical model and the performance of the engine and the exhaust emissions were investigated by experiments. A thermodynamic model that includes real cycle calculations of the engine has been developed for theoretical cycle analysis and the diagrams that reveal the performance of the engine has been obtained by writing a computer program that was developed in MATLAB programming language. In the experimental stage of this study, firstly, the experiments were realized in order to determine the engine performance parameters at under full and low loads, between 1000 rpm and 2000 rpm engine revolution by changing it with 200 rpm interval. Then, the engine was started at 1800 rpm fixed speed with full and partial loads and the exhaust emission values were determined. The theoretical analysis results and empirical results of the engine performance parameters were compared to each other. Also, the empirical results have been compared with the performances of a classical two-stroke engine and a four-stroke engine

Bu çalışmada, iki zamanlı ters-doğru akışlı, karbüratörlü, buji ile ateşlemeli bir motorun çevrim
analizi teorik matematiksel model kullanılarak belirlenmiş ve yapılan deneylerle motorun
performansı ve egzoz emisyonları incelenmiştir. Teorik çevrim analizi için motorun gerçek
çevrim hesaplamalarını içeren termodinamik bir model geliştirilmiş ve bu modele göre MATLAB
programlama dilinde bir bilgisayar programı yazılarak motorun performansını ortaya koyan
diyagramlar elde edilmiştir. Yapılan bu çalışmanın deneysel aşamasında öncelikle, motor
performans parametrelerinin belirlenmesi amacıyla, tam ve kısmi yüklerde, 1000 rpm ile 2000
rpm arasında 200 rpm aralıklarla motor devri değiştirilerek deneyler gerçekleştirilmiştir. Daha
sonra, motor 1800 rpm’lik sabit hızda, tam ve kısmi yüklerde çalıştırılarak egzoz emisyon
değerleri belirlenmiştir. Motor performans parametrelerinin, teorik analiz sonuçları ve deneysel
verileri birbirleriyle karşılaştırılmıştır. Ayrıca elde edilen deneysel sonuçlar klasik iki zamanlı bir
motorun ve dört zamanlı bir motorun performans değerleriyle kıyaslanmıştır.
