Problem 4An ideal Diesel cycle has a maximum cycle temperature of 2300 °F. The state of the air at thebeginning of the compression is 14.4 psia and 50 °F. This cycle is executed in a four-stroke, eight-cylinder engine with a cylinder bore of 4 in and a piston stroke of 4 in. The minimum volumeenclosed in the cylinder is 4.5% of the maximum cylinder volume. Determine the power producedby this engine when it is operated at 1800 rpm.
