Q3: A diesel engine that has a bore D=110 mm and the stroke S=120mm. the length of the connecting rod is l=210mm and the masses of the piston assembly and the connecting rod are 3.5 kg and 2.3 kg respectively. 1. Determine he position of the center of mass of the connecting rod knowing that mc-tr =0.29 mcr. 2. Calculate the forces loading the crank pin and the connecting rod bearing at 2400 rpm for the crank slider position corresponding to a crank angle 110 (during intake) knowing that the cylinder pressure at this position is 0.09MPA. the crankcase pressure may be assumed to be 0.1Mpa. specify the directions of the forces with respect to the crank axis and with respect to connecting rod axis.

Question
Q3: A diesel engine that has a bore D=110 mm and the stroke S=120mm.
the length of the connecting rod is /=210mm and the masses of the piston
assembly and the connecting rod are 3.5 kg and 2.3 kg respectively.
1. Determine he position of the center of mass of the connecting rod
knowing that mc-tr =0.29 mcr.
2. Calculate the forces loading the crank pin and the connecting rod
bearing at 2400 rpm for the crank slider position corresponding to
a crank angle 110 (during intake) knowing that the cylinder
pressure at this position is 0.09MPA. the crankcase pressure may
be assumed to be 0.1Mpa. specify the directions of the forces with
respect to the crank axis and with respect to connecting rod axis.
