A turbocharged 4-stroke medium speed Diesel engine has a cylinder bore of 200 mm and a stroke of 270 mm. The turbocharger supplies a constant 2.5 bar of absolute to each cylinder when the engine is running at 85% load at 1000 rpm. Assume that the intake air at each cylinder is a constant 25 °C and that the ideal gas law applies. specific gas constant of air is 0.2870 Estimate the mass of air that enters each cylinder during the intake stroke. kek Answer in units of grams. Enter only the number, do not enter units. Use your answer from the Diesel engine problem above. Assume that the engine is operated such that Diesel fuel is injected into each cylinder at a ratio of 1-to-18 parts of fuel to air. Estimate the fuel consumption of the engine per hour. Note that the engine has twelve cylinders in total. Answer in units of kilograms per hour. Enter only the number; do not enter units.

Transcribed Image Text:A turbocharged 4-stroke medium speed Diesel engine has a cylinder bore of 200 mm and a stroke of 270 mm. The turbocharger supplies a constant 2.5 bar of absolute pressure
to each cylinder when the engine is running at 85% load at 1000 rpm. Assume that the intake air at each cylinder is a constant 25 °C and that the ideal gas law applies. The
specific gas constant of air is 0.2870h Estimate the mass of air that enters each cylinder during the intake stroke.
Answer in units of grams. Enter only the number, do not enter units.
Use your answer from the Diesel engine problem above. Assume that the engine is operated such that Diesel fuel is injected into each cylinder at a ratio of 1-to-18 parts by mass
of fuel to air. Estimate the fuel consumption of the engine per hour. Note that the engine has twelve cylinders in total.
Answer in units of kilograms per hour. Enter only the number; do not enter units.
