$1.$ Draw the timing events determined for this engine specification a four$-$stroke cycle $6\mathrm{.}7-$liter in$-$line six$-$cylinder turbocharged diesel engine. Bore $107$ mm$,$ stroke $124$ mm$,$ compression ratio $17\mathrm{.}3$ on a valve event timing diagram. Clearly identify intake valve opening, intake valve closing, exhaust valve opening, and exhaust valve closing. Also identify piston TDC and piston BDC$.$ Finally, identify intake stroke, compression stroke, combustion$/$expansion stroke, and exhaust stroke. NOTE: you may hypothesize your own timing events if you$$re not able to determine them for your favorite engine.
