"Penelitian mengenai pembakaran telah mengalami perkembangan yang pesat di segala bidang. Penelitian yang akan dilakukan adalah pada arah menjaga kestabilan nyala api jauh dari ujung burner dengan memasang ring. Salah satu parameter yang diamati adalah temperatur ringnya yang diukur menggunakan infra red thermometer. Tujuan penelitian ini adalah untuk mengetahui besarnya temperatur yang terukur pada ring keramik maupun ring stainless steel pada saat fenomena flame lift-up terjadi. Parameter yang divariasikan pada penelitian ini adalah jarak ring dengan mulut tabung pembakar.Dari penelitian ini didapatkan hasil bahwa pada jarak ring yang sama atau tetap, semakin tinggi nilai burning load maka temperatur ring juga ikut meningkat. Selain itu juga dapat diketahui bahwa temperatur ring stainless steel lebih tinggi dibandingkan dengan temperatur ring keramik .Namun panjang nyala api pada ring stainless steel lebih pendek dibandingkan dengan panjang nyala api pada ring stainless steel pada saat fenomena flame lift-up terjadi.

Research on burning has had a rapid development in all sectors. Research will be done is to maintain stability in the direction away from the flame to the burner tip install ring. One of the observed is the ring temperature measured using infra red thermometer. Goal of this research is to understand the magnitude of temperature measured on the ring ceramics and stainless steel ring at the time phenomenon flame lift-up occurred. Parameters varied in this research is the distance to the mouth tube ring burner.From the results of this research found that the ring on the distance or remain the same, the higher the value of the load burning ring temperature also increases. It also can note that the stainless steel ring temperature higher than the temperature ceramic ring. But the length of the flame on the stainless steel ring shorter than the length of the flame on the stainless steel ring at the time phenomenon flame lift-up occurred."

"This book deals with in-cylinder pressure measurement and its post-processing for combustion quality analysis of conventional and advanced reciprocating engines. It offers insight into knocking and combustion stability analysis techniques and algorithms in SI, CI, and LTC engines, and places special emphasis on the digital signal processing of in-cylinder pressure signal for online and offline applications. The text gives a detailed description on sensors for combustion measurement, data acquisition, and methods for estimation of performance and combustion parameters. The information provided in this book enhances readers basic knowledge of engine combustion diagnostics and serves as a comprehensive, ready reference for a broad audience including graduate students, course instructors, researchers, and practicing engineers in the automotive, oil and other industries concerned with internal combustion engines.Maximizes readers understanding of the construction, working principles, installation, signal processing and limitations of the transducers used for combustion analysis;Provides a range of different models for estimating heat release and heat transfer for combustion quality analysis;Describes statistical and chaotic methods used for combustion stability analysis and the different knock indices and combustion noise metrics evaluated from cylinder pressure signal;Reinforces concepts presented with end of chapter summary discussions and questions;Explains methods used for estimation of engine parameters such as TDC, compression ratio, air-fuel ratio, residual gas fraction and wall temperature using in-cylinder pressure measurement."
