ELEKTROMANYETİK SUPAP İLE ÇALIŞAN BİR PNÖMATİK MOTOR İÇİN KONTROL ÜNİTESİ TASARIMI VE MOTOR PERFORMANSINA ETKİSİ

Bu çalışmada, 2 zamanlı içten yanmalı 49 cc’lik bir benzinli motor basınçlı hava ile çalışır hale getirilmiştir. Havanın silindir içerisine gönderilmesinde, bir elektromanyetik supaptan faydalanılmıştır. Elektromanyetik supabın kontrolü için Atmega8 mikrodenetleyicisinin kullanıldığı bir elektronik kontrol devresi tasarlanmış ve imal edilmiştir. Basınçlı hava, silindir içerisine farklı emme supap zamanlamalarında gönderilmiş ve motor performans değerleri karşılaştırılmıştır. Sonuçta elektronik kontrol devresi elektromanyetik supabı yaklaşık olarak 1600 1/min motor hızı için başarılı bir şekilde kumanda ettiği görülmüştür.

Anahtar Kelimeler:

Pnömatik motor, elektromanyetik supap, mikrodenetleyici, atmel
