A 4-cylinder, 4-stroke cycle turbocharged diesel engine has a cylinder bore of 4. 5 in. and the piston moves a distance of 5.0 in. from HDC to CDC. Each cylinder's volumetric displacement (in.3) is: The crankshaft throw in inches for each crankpin (connecting rod bearing) journal is: If the compression ratio is 16.5, the combustion chamber volume (in.3)in each cylinder is: Review For Test 1-Problems
A 4-cylinder, 4-stroke cycle turbocharged diesel engine has a cylinder bore of 4.5 in. and the piston moves a distance of 5.0 in. from HDC to CDC. If the ideal diesel cycle volume V3 (where fuel injection cuts off) is 15.52 in.3, the fuel cutoff ratio is: The ideal cycle efficiency (%) for this engine is: If the turbocharger for this engine delivers 501 ft3/min of air to the intake manifold at an engine speed of 2400 rpm, what is its volumetric efficiency (%)?
