Abstract

In the conventional internal combustion engines, the elements of linear movement cause the friction power to increase the manufacturing economy to deteriorate and also cause vibration. The diameter of intake valves, which is smaller than the diameter of the cylinder, causes the volumetric efficiency to decrease. In the two stroke engines, in which the number of work per cycle is increased, power output per unit volume (kW/liter) is higher; however, specific fuel consumption decreases considerably. In this study, an alternative elliptic internal combustion engine, in which crankshaft, camshaft and valve mechanism are not used, has been designed and its prototype has been manufactured. The elliptic engine works on 4 stroke Otto cycle principle. However, the cycle is completed in 360 degrees. The first prototype has been manufactured and proved workable. And the problems related to the first prototype have been determined. It has been anticipated that by eliminating the problems that affect the running of the first prototype, some advantages for the second prototype could be obtained such as improved manufacturing economy, increase in the mechanical efficiency and decrease in the specific fuel consumption. Furthermore, the patent application of this new engine has already been made.

Özet

Geleneksel pistonlu motorlarda doğrusal hareket elemanları, sürtünme gücünün artmasına, imalat ekonomisinin kötüleşmesine ve titreşime sebep olmaktadır. Silindir çapına göre küçük olan emme supabı çapı volümetrik verimi düşürmektedir. Çevrim başına iş sayısının arttırıldığı iki zamanlı motorlarda kW/litre gücü daha yüksek olmakta, buna karşılık özgül yakıt tüketimi kötüleşmektedir. Bu çalışmada, krank mili, kam mili ve supap mekanizması kullanılmayan alternatif bir eliptik içten yanmalı motor tasarımı yapılmış ve prototipinin imalatı gerçekleştirilmiştir. Eliptik motor, 4 zamanlı Otto çevrimi esasına göre çalışmaktadır. Ancak çevrim 360 derecede tamamlanmaktadır. İlk prototip imal edilmiş ve motorun çalışabilirliği kanıtlanmıştır. İlk prototiple ile ilgili sorunlar belirlenmiş, bu sorunların giderilmesi ile ikinci prototipte imalat ekonomisi, mekanik verimin arttırılması ve özgül yakıt tüketiminin azaltılması gibi avantajların sağlanabileceği anlaşılmıştır. Ayrıca motorun patent başvurusu yapılmıştır.
