11. (10 points) Look at the piston, connecting rod and crankshaft carefully. In modern engines piston is cooled by oil jet. Oil is initiated at the base of the cylinder and targets the underside of the piston, In this regard, it is important to have enough oil flow rate to strike the piston at all times. Consider an in-line 4 cylinder engine with crank radius 45 mm, connecting rod leneth 154 mm. Si = R cosoi + (1 - R2sin p)/2 TOC TDC V, te Where "s" is the distance between the crank axis and the piston pin axis and index "* represent cylinder number Develop the piston displacement curve (as a function of crank angle), piston velocity, oil jet velocity, and oil jet velocity relative to piston velocity for 6000 engine rpm, all in one plot. Oil flow rate from a 2 mm diameter nozzle is "Ilast two digits of your ID/20" liters/min.
