Cutoff ratio diesel cycle
WebAn ideal Diesel cycle has a maximum cycle temperature of 2300°F and a cutoff ratio of 1.4. The state of the air at the beginning of the compression is P1=14.4 psia and T1=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 volume enclosed in the cylinder is ...
