Munsin and faculty [29] to study combustion characteristics (Combustion characteristic). Of ethanol fuel with water as a percentage composition 5 by volume (Eh95) mix the ignition ต่างชนิด. For example, the additive commercial. (Commercial additive ED95), glycerol, eat อกซี isolates (Glycerol ethoxylate) biodiesel (Biodiesel) and diet butyl ether (Diethyl. Ether) as shown in table 2.2 test under the condition of compression ignition engine. Using compression machinery and expand quickly (Rapid compression and expansion machine RCEM), which all test conditions specified ให้อุณหภูมิ after compression equals. 900K the results showed that the ethanol fuel with water as a percentage composition 5 by volume of mixed additives commercial (ED95) and ethanol fuel with water as a percentage composition 5 by volume mixing glee เซอรอล eat อกซี location 5 percent by volume. (5%GE) delay ignition at the same time, as shown in Figure 2.15 noted that เชื้อเพลิงทั้งสอง species will delay ignition about 0.9 MS. Which generally delay ignition for diesel engine with low compression ratio, injection directly into the cylinder to be between 0.6 - 3 ms. Diesel engine with high compression ratio and injection directly into the cylinder with turbo charged layer is between 0.4 - 1 30 ms [] that demonstrate the feasibility of using ethanol for compression ignition engines.From figure 2.16 found that ethanol fuel with water as a percentage composition 5 by volume of mixed additives commercial (ED95) and ethanol fuel with water as a percentage composition 5 by volume mixing biodiesel รอลอี tok C location 5 percent by volume. (5%GE) combustion characteristics similar. There was a mixed burning period (Premixed combustion phase) than other types of mixed fuel But to the combustion is controlled by mixing (Mixing controlled combustion phase), which can be observed clearly in the graph between the heat release rate time after injection of fuel. In the case of other types of fuel mixture to the combustion mixture. Due to the increase of delay ignition, which infections.
