Abstract
Among the challenges faced by diesel engines combustion nowadays are to reduce emission especially Nitrogen Oxide (NOx) and Particular Matter (PM) while enhancing fuel efficiency and power. The purpose of this review is to explore the mixture formation of biodiesel combustion using constant volume chamber and optical visualization. This paper will review the development of a single-shot combustion system and constant volume chamber. An overview of the relation of mixture formation and combustion process in diesel combustion is provided first. This review has shown that the application of Rapid compression Machine (RCM) is used to simulate actual condition especially the injection pressure and air motion. The review also found that the mixing between fuel and air is unavoidable and very important during ignition delay period thus predominantly influences the exhaust emission. The detailed behaviour of injection characteristic that strongly effects the mixture formation especially the spray evaporation and spray interference are discussed.Keywords: Rapid Compression Machine; Ignition Delay; Nozzle; Injection System; Air Motion; Ambient

Summary
The challenge for the diesel engine today is to reduce raw emission such as Nitrogen Oxide (NOx) and Particular Matter (PM). To meet this challenge, the mixture formation is indispensable to improve exhaust emission from diesel engine must be control especially fuel-air mixing at early of ignition process [1,2,3,4,5]. Various phenomena that involved in the diesel combustion, the physical factor plays a significant role in the ignition of diesel sprays and linked to the improvement of exhaust emission by fuel-air premixing. The focusing improvement mixture formation in delay ignition such as, ambient gas pressure, fuel system, pressure and temperature of air. The methodology of this review is using Rapid Compression Machine (RCM) with single-shot of common rail system
