Question

Requirement: You are designing a 4-stroke Diesel engine (turbocharged) to provide a brake power of 300 kW at MBP point.
Deliverables (minimum)
- Engine displacement
- Number of cylinders
- Bore and stroke
- Connecting rod length
- Crank off-set
- Brake mean effective pressure,
- Average piston speed,
- Brake torque,
- Fuel flow rate,
- Specific fuel consumption,
- Power per unit displacement.
- Pressure after turbocharger (how did you choose/calculate/determine this value?)
How would the performance parameters change at the MBT point? Could you give an estimate of these parameters at MBT?
All parameters should be within typical, reasonable ranges and should be consistent with other values. State all your assumptions (mechanical efficiency, volumetric efficiency…) clearly.

Explanation / Answer

At the rate of 1200km pm,you would need a displacement of 204 cubic in at 404bpm with a stroke of 2.78 and a bore of 3.007 to make a 300kw brake torque and 1.7gph at 750.001bmep
