Subaru Legacy 3.0 R Spec B manufactured in 2005 has an engine capacity of 3.0 liters SI V6 engine operating on a four-cycle at 6600

Subaru Legacy 3.0 R Spec B manufactured in 2005 has an engine capacity of 3.0 liters SI V6 engine operating on a four-cycle at 6600 rpm. the compression ratio is 10.5:1 with a connecting rod length of 20cm and engine is over square where B = 1.15 S. At this speed the combustion end at 20°C after TDC . The engine can attain a maximum power of 179 kw at 6600 rpm and a maximum torque of 326.7 Nm at 4200 rpm. At the speed of 6600 rpm the air enters the cylinder at 98kPa and at a temperature of 40°C with a mechanical efficiency of 80 percent. The engine runs with an air-fuel ratio of 14.7 with gasoline fuel having a low heating value of 44,000 kJ /kg and combustion efficiency of 92 percent.

At maximum power output calculate:

1) Cylinder bore and stroke length

2) Average piston speed

3) Clearance volume for one cylinder

4) The piston speed at the end of Combustion

5)The distance the piston travel from TDC at the end of combustion

6) Indicated and brake power

7) Indicated mean effective pressure

8) Power lost to friction

9) The rate of fuel flow into the engine

10) Brake thermal efficiency and indicated thermal efficiency

11) Volumetric efficiency

12) Brake specific fuel Consumption
