Abstract

Electro Mechanical Valve (EMV) actuators are currently being developed by many researchers and engine and automotive component manufacturers. These actuators can potentially improve engine performance via flexibility in valves timings at all engine operating conditions. Unlike conventional camshaft driven systems, EMV system affords valve timings that are fully independent of crankshaft position. Thus the electromechanical valve train technology allows controlled opening and closing events for intake and exhausts valves and offers a big potential to minimize the fuel consumption and the emissions. The purpose of this study is to investigate dynamic performance of an EMV system, which has 12-volt supply voltage, at different lifting valve operations and thus to determine the support limits of an internal combustion engine.

Özet

Elektromekanik supap (EMS) sistemleri çok sayıda araştırmacı, motor ve otomotiv parça üreticileri tarafından geliştirilmektedir. Bu sistemler motorun tüm çalışma koşulları için supap zamanlamasında sağladığı esneklik sayesinde, potansiyel olarak motor performansını iyileştirme kabiliyetine sahiptir. EMS sistemleri, konvansiyonel kam mili sistemlerinin aksine supap zamanlamasını krank mili pozisyonundan tamamen bağımsız olarak gerçekleştirir. Bu sayede elektromekanik supap teknolojisi emme ve egsoz supaplarının açılma ve kapanma olaylarının denetimine imkân sağlayarak yakıt tüketimi ve emisyonların en aza indirilmesinde büyük bir potansiyele sahiptir. Bu çalışmanın amacı, 12Vluk besleme gerilimine sahip bir EMS sisteminin değişik supap çalışma aralığındaki dinamik performansını araştırmak ve böylece içten yanmalı bir motoru destekleme limitlerini belirlemektir.
