A 3 liters S.I. V6 engine that operates on a four-stroke of 3000 olution per minute, the compression ratio is 10, the lengths of the necting rod and the crank offset are 15 cm and 4 cm respectively, combustion is completed at 35° of the crankshaft rotation after I need an answer as soon as possible, and I hope it will be clear. Greetings, my bro. C, the engine is running with the stoichiometric air-fuel ratio, chanical efficiency 90%. If the engine is connected to a dynamometer ch its reading of 100 kW. -culate: 1-piston speed at end of the combustion, 2-volume of the mbustion chamber at end of the combustion, 3-engine torque, 4- icated mean effective pressure and 5-break specific fuel consumption.

A compression-ignition engine with compression ratio of 14 is being designed. Pressureand temperature at the bottom dead centre are 1.3 bar and 400K. The engine operatesaccording to the standard Diesel cycle. Assume polytrophic index to be 1.33. Computepressure and temperature at the top dead centre

14 A six-cylinder SI engine with a compression ra tio of 10.5:1 oper ates on a four-stroke cycle at 3000 RPM. Air enters the cylinders at T = 110 F and P = 12.8 psia. The intake valve closes at 20° BDC and combustion starts when the spark plug fires at 15 6TDC. Con- necting rod length is 6.64 in. and crank offset is 1.66 in. Calculate: (a) Cylinder temperature at start of combustion using air-standard Otto cyde analysis ['F] (b) Cylinder temper ature when spark plug fires assuming compression doesn't start until intake valve closes.
