Abstract

In my work , I investigates the effect of  initial temperature of diesel fuel upon engine performance and emissions by using CI engin , with different diesel fuel cetane number ( 56 , 54 , 53 ) ,  from the results it showing us that the  brake power is increasing with the engine speed and the increasing is (64.66 %) at maximum load with respect with brake power at minimum load ,also measuring the brake torque and it is found from the results the brake torque is increasing with the engine speed at minimum and maximum load and from the results it is found that the brake torque is increasing about (63.902 %) when compare it with brake torque at minimum load ,fuel consumption(kg/hr)  is increasing  with the engine speed but decreasing when increasing  cetane number with the following values (6.631%,7.843%,9.15%) for cetane number ( 53,54,56 ) , and the brake specific fuel consumption also decreasing about (6.065%,6.98%,8.654%) for Cetane number (56,54,53) respectively  , the thermal efficiency it is found to be increased with the engine speed  and for different fuel cetane number with the following percentage (5.96%,6.837%,8.498%) for Cetane number (53, 54 , 56) respectively, The ( CO2 ) emissions is increased with the engine speed and  when the Cetane number increased about (11.35%,9.457%,11.065%) for cetane number  (56,54,53) respectively , The (CO) emissions is decreased  when the Cetane number increased about (24.165%,20.581%,21.7%) for Cetane number (56,54,53) respectively , The (HC) emissions is decreased  by increasing fuel Cetane number about (8.695%,10%,9.586%) for Cetane number (53 , 54 , 56) respectively.
