静电喷雾燃烧技术对降低发动机怠速油耗的实验研究

Experimental Study on Electrostatic Spray Combustion Technology in Fuel Consumption of Engine Idle Speed

针对桑塔纳2000AFE型发动机,根据静电雾化原理,搭建了基于静电喷雾燃烧技术的发动机怠速试验台.在喷油器的支架入口安装了一个触网式静电雾化装置,用电子称、废气分析仪等相关仪器对加上静电前后的发动机怠速油耗和排放进行了测试,结果表明,静电喷雾燃烧技术对发动机怠速工况的节油和改善排放的效果明显.

Electrostatic spray can apparently improve the fuel atomization. Based on the Santana 2000AFE engine, engine test equipment was built to experimentally study the effect of the electrostatic spray combustion technology on the fuel consumption and the emission in the case of engine idle speed. The entry of the injector bracket was installed an OCS electrostatic atomization devices, and the engine idle fuel consumption and emissions froe-and-aft the static electricity is tested by electronics scale, exhaust gas analyzer and other related equipment. The results show that the electrostatic spray combustion technology can obviously improve the oil saving and emission. Below at 1000r/min engine speed, fuel economy up to 3% ; in all idle speed, HC emissions decrease up to 10% - 17% , CO emissions increase up to 5% to 25%.
