Question
Design a cast iron piston for a single acting four stroke engine for the following data:
Cylinder bore = $100\text{mm}$; Stroke = $125\text{mm}$; Maximum gas pressure = $5\text{ N/mm}^2$; Indicated mean effective pressure = $0.75\text{ N/mm}^2$; mechanical efficiency = $80\%$; Fuel consumption = $0.15\text{ kg}$ per brake power per hour; Higher calorific value of fuel = $42\times 10^3\text{ kJ/kg}$; speed = $2000\text{ rpm}$. Any other data required for the design may be assumed.
