Engineering

According to data provided by Motor Trend, the 2011 Chevrolet Silverado Diesel HD is powered by an 8 cylinder diesel engine having a total displacement of 6599 cc (6.599 L). The compression ratio is 16:1, and the total power output is 397 hp (296.0 kW) at a crankshaft speed of 3000 RPM (see link below). Model the engine assuming a non-ideal Diesel cycle where the intake air conditions are 360 K and 200 kPa, and that the compression and power stroke efficiencies are 90%. Using the provided engine data, determine:

a) the charge mass (grams).

b) the cut-off ratio.

c) the engine efficiency.

Hint: it may be necessary to guess the temperature, then compare the specific work; you may use constant average specific heat for any process having an begin/end state temperature outside the range of the ideal gas air table.
