Design a 140 IIP Horse Power engine for use in an automobile

Design a 140 IIP (Horse Power) engine for use in an automobile. Suggestions: 1) Decide the kind of fuel the engine will be using. 2) Select the material of the engine and determine the maximum allowable temperature and pressure in the engine. 3) Design the cycle on which the engine will be operating. 4) Determine the basic physical dimensions of the engine. 5) Determine the values of the basic design parameters of the engine.

Solution

Fuel can be Diesel or Gasoline(Petrol)

The material of the Engine are mainly Cast Iron Alloys, Structural Steels,Aluminium alloys.

Otto Cycle, Diesel Cycle can be employed.

Bore : 91mm and Stroke :96mm.

Inline cylinders position and Compression Ratio around 19 for diesel cycles,Compression ratio around 10.3 for Otto Cycles.
