A horizontal gas engine running 210 rpm has a bore of 220 mm and a stroke of 440mm. The connecting rod is 924 mm long and the reciprocating parts weights 20 kg, when the crank has turned through an angle of 33 degrees from the inner dead center, gas pressure on the cover and the crack sides are 500KN/m and 60 KN/ m respectively. Diameter of the piston rod is 40mm. - Determine - 1. turning moment on crank shaft. - 2. thrust on the bearing. - 3. acceleration of the flywheel which has a mass of 8 kg and radius of gyration of 600mm while the power of engine is 22Kw. -

Given:

D=0.22m; Ls= 0.44m

Θ= 30; N = 210rpm

Lc= 0.924m

M= 20kg

P1 = 500kPa; P2= 60kPa

Dp= 0.04m

Mf = 8kg; r= 0.6m; P= 22kw

To find:

Moment

Thrust

acceleration

First we need to determine all angles.

Now by applying sine rule, we can get the angle of …
