A methodology for a HCCI-Gasoline engine design using the parameters of double injection and intake air temperature

Öz:

Homojen doldurmalı sıkıştırmayla ateşleme (HCCI), düşük emisyonlu motor tasarımı olarak dikkat çekmektedir. Bu motor tipinin optimum çalışma şartları hakkında çok az bilgi bulunmaktadır. Düşük yakıt eşdeğerlik katsayısı koşullarındaki homojen karışımın yanması, çok yüksek olmayan sıcaklıklarda olmakta ve geleneksel motorlara göre düşük NOx (nitrojen oksit) ve PM (partikül) konsantrasyonları içeren yanma ürünleri ortaya çıkmaktadır. Bununla birlikte; yüksek ısıl verim elde edilen bu yanma tipinde daha fazla HC (hidrokarbon) ve CO (karbon monoksit) emisyonları oluşabilmektedir. Bu çalışmada, elektronik kontrollü, tek silindirli, direk püskürtmeli bir ağır yük dizel deney motoru, HCCI motoruna dönüştürülmüştür. Bü motor üzerine elektronik kontrollü, düşük basınçlı, 60° püskürtme açılı ve kademeli püskürtme özelliğine sahip, "common rail" tipi bir enjektör monte edildikten sonra emisyon kontrolü için kademeli püskürtme kullanımı uygulanmış ve mikro-genetik algoritma optimizasyon kodu ile bilgisayar kontrollü deneyler yapılarak motorun çalışması optimize edilmiştir. Optimizasyon kapsamındaki değişkenler; emme havası giriş sıcaklığı, püskürtme başlangıç zamanı, ve her bir püskürtmedeki yakıt yüzdesinde değişim ve iki püskürtme aralığında değişim gibi farklı püskürtme parametreleridir. Motor performansı ve emisyonlar, 10 MPa yakıt basıncında ve 700 d/dak motor hızında ölçülmüştür. Sonuçlar optimum püskürtme stratejisinin kullanımı ile önemli emisyon azalmalarının olabileceğini göstermektedir.

Homogeneous charge compression ignition (HCCI) is receiving attention as a new low emission engine concept. Little is known about the optimal operating conditions for this engine operation mode. Combustion at homogeneous, low equivalence ratio conditions results in modest temperature combustion products, containing very low concentrations of NOx (nitrogen oxides) and PM (particulate matter) as well as providing high thermal efficiency. However, this combustion mode can produce higher HC (hydrocarbon) and CO (carbon monoxide) emissions than those of conventional engines, An electronically controlled Caterpillar single-cylinder oil test engine (SCOTE), originally designed for heavy-duty diesel applications, was converted to a HCCI direct-injection gasoline engine. The engine features an electronically controlled low pressure common rail injector with a 60°-spray angle that is capable of multiple injections. The use of double injection was explored for emission control, and the engine was optimized using fully-automated experiments and a micro-genetic algorithm (GA) optimization code. The variables changed during the optimization had included the intake air temperature, start of injection timing, and split injection parameters (percent mass of the fuel in each injection, dwell between the pulses). The engine performance and emissions were determined at 700 rev/min with a constant fuel flow rate at 10 MPa fuel injection pressure. The results showed that significant emissions reductions are possible with the use of optimal injection strategies.
