Implementation and Results of Pneumatic Fuel Atomization in Diesel.

The specific characteristics of a diesel engine with pneumatic fuel atomization are described in the article. Possible variants of embodiments of fuel pneumatic atomization in diesel engines are suggested. To obtain compressed air for fuel atomization, the authors considered to use a compressor driven by electrical power received from high frequency electric generator, which is located between the gas turbine and the charge air, the blower is powered by exhaust gas energy is the most appropriate. The results of comparative experiments on diesel 1CHN15,0/20,5 in original and experimental configuration with pneumatic atomization of fuel are provided. These materials presented an obvious advantage of the pneumatic atomization regarding the emission of hazardous air pollutant, indicators workflow and features of the combustion process flow; particularly the ignition delay period has decreased almost by 80%. The pressure ratio was significantly reduced and the degree of pre-expansion increased dramatically. [ABSTRACT FROM AUTHOR]
