커먼레일을 이용한 디젤과 BD20 연료가 인젝터에 미치는 영향에 관한 연구

The characteristics of diesel and biodiesel are similar like as cetane number and auto-ignition temperature. High cetane number of diesel and BD could make possible to compression ignition. but BD showed different atomization from diesel due to component like density, viscosity and iodine value etc....

Summary:The characteristics of diesel and biodiesel are similar like as cetane number and auto-ignition temperature. High cetane number of diesel and BD could make possible to compression ignition. but BD showed different atomization from diesel due to component like density, viscosity and iodine value etc. Because of this, the biodiesel requires validation. This study using diesel and BD20 investigated effect to durability injector. Durability test were used common rail and bosch solenoid type 5-hole injector. Total test was 672hr but actual running time was 200hr. Spray experiments for spray characteristics were carried out using constant volume combustion chamber. Spray characteristics of diesel and BD showed different result up to durability test time. After 100hr, diesel showed spray shapes were stable but BD was not. After 200hr, difference of diesel and BD spray shapes were grow serious.
