A8 cylinder, 4 stroke diesel engine has a power output of 368 kW at 800 rpm. The fuel consumption is 0.23$ kg/kW.hr. The pressure in the cylinder at beginning of injection is 35 bar and the maximum cylinder pressure is 00 bar. The injector is expected to at 210 bar and the maximum pressure in the injector is set to be 600 bar Calculate the orifice area required per injector if the injection take place over 12° crank angle. Assume the coefficient of discharge for the injector 0.6, specific gravity of fuel 0.85 and the atmospheric pressure 1.013 bar. Take the effective pressure difference to be the average pressure difference over the injection period.

Asphalt Binders and Mixtures

Asphalt binders are subsidiary products procured during the refining process of petroleum while manufacturing gasoline, diesel, and similar petroleum products. Asphalt binders are obtained from the residue that remains after the distillation of petroleum, this residue is further subjected to steam distillation and oxidation to remove the traces of gas oil present in the residue. Certain additives or modifiers are also added to asphalt binders to alter them to suit different applications.
