The fuel efficiency of internal combustion engines were evaluated in three basic tests done on several diesel trucks with an aim to improve the performance of the engines, thereby exhibiting the significant fuel mileage improvement and reduction of emission. The tests employed a typical four stroke cycle-engine with two widely used ideal models of engine combustion process: constant-volume combustion process and constant-pressure combustion process. The study also emphasized the 10-20 years vehicles with internal combustion engines have improved their fuel mileage more than 30%, where most of them come from improving the combustion with increasing fuel pressure or new fuel droplets. The results concluded that in addition to reducing the average droplet size, as the viscosity of the fuel was reduced, many small droplets with a diameter of several micrometers with our device.
