Problem 3 (5 points): A CI engine with bore B 7.2 cm has the fuel injectors mounted in the center of the cylinder head. The injectors have a nozzle diameter of 0.07 mm, a discharge coefficient of 0.7, and an injection pressure of 52 MPa. Average cylinder pressure during injection can be considered 5500 kPa. Density of the diesel fuel is 860 kg/m3 Calculate: 1. Average velocity of the fuel jet as it leaves the injector. [m/sec 2. Time for a fuel particle to reach the cylinder wall if it traveled at average exit velocity.
