Abstract

In this study, an electronic
control unit was designed and developed for a single rotor Wankel engine. The
code was written the Arduino IDE. An interface is designed in Visual Studio for
computer control of a single rotor test engine. Thanks to the control unit, the
injection advance, injection duration, engine speed, dwell time and ignition
advance were controlled. In the hardware part, firstly solid state relay was
used for switching, and then a MOSFET circuit was tested. It was observed that
the ignition and spraying signals received from the oscilloscope for both
switching came regularly and continuously at different speeds (600, 1000 and
3000 rpm). Afterwards, according to the results obtained with the oscilloscope
and high speed camera, there was no delay in opening time of the injector with
the solid state relay. However, there was 0.6 milliseconds delay in closing time
of it. This situation caused the engine to run erratically and unstable at high
speeds. In the circuit established with Mosfet, there was no delay at the
opening and closing times of the injector. As a result, it was concluded that
it would be more appropriate to use the circuit designed with MOSFET in the
control unit.

Bir Wankel Motorda Ateşleme ve Püskürtme Üniteleri İçin Elektronik Kontrol Ünitesinin Geliştirilmesi

Abstract

Bu çalışmada,
tek rotorlu bir Wankel motoru için elektronik kontrol ünitesi tasarlanmış ve
geliştirilmiştir. Kod Arduino veri tabanında yazılmıştır. Tek rotorlu test
motorunun bilgisayar kontrolü ile Visual Studio'da bir ara yüz tasarlanmıştır.
Kontrol ünitesi sayesinde püskürtme avansı, püskürtme süresi, motor hızı, bobinin
dolma süresi ve ateşleme avansı kontrol edilmiştir. Donanım bölümünde, ilk önce
anahtarlama için katı hal rölesi kullanılmış ve daha sonra bir mosfet devresi
ile test edilmiştir. Her iki anahtarlamada osiloskoptan alınan ateşleme ve
püskürtme sinyallerinin düzenli ve sürekli olarak farklı hızlarda (600, 1000 ve
3000 rpm) geldiği gözlenmiştir. Daha sonra, osiloskop ve yüksek hızlı kamera
ile elde edilen sonuçlara göre, katı hal rölesi ile enjektörün açılmasında
herhangi bir gecikme olmamıştır. Ancak, enjektörün kapanması 0.6 milisaniye
geciktiği gözlemlenmiştir. Bu durum, motorun özellikle yüksek hızlarda düzensiz
ve dengesiz çalışmasına neden olmuştur. Mosfet ile kurulan devrede, enjektörün
açılıp kapanmasında herhangi bir gecikme olmamıştır. Sonuç olarak, kontrol
ünitesinde mosfet ile tasarlanan devrenin kullanılmasının daha uygun olacağı
sonucuna varılmıştır.
