An engine working on otto cycle has the bore of 10 cm and crank radius of 7.5 cm. The clearance volume of the engine is 196.3 cc. Calculate (a) Clearance ratio. (b) Air standard efficiency.
Added by Teresa C.
Step 1
The stroke length is twice the crank radius. \[ \text{Stroke length} = 2 \times \text{Crank radius} = 2 \times 7.5 \, \text{cm} = 15 \, \text{cm} \] Show more…

A four-stroke gasoline engine has a compression ratio of 10: 1 with four cylinders of total displacement $75 \mathrm{in} .^{3} .$ The inlet state is $500 \mathrm{R}$ 10 psia and the engine is running at 2100 RPM, with the fuel adding $600 \mathrm{Btu} / \mathrm{lbm}$ in the combustion process. What is the net work in the cycle and how much power is produced?
