Q) A single-cylinder two-stroke SI cngine has 8 cm diameter bore and 10 cm stroke. The compression ratio is 8. The exhaust port opens 60° before BDC and closcs 60° after BDC. The air/fucl ratio is 15.1. The temperature of the mixture cntering into the engine is 300 K and the pressure in the cylinder at the time of closing the exhaust port is 1.05 bar. Take R for the mixture 290 J/(kg K), Air supplied to the engine is 150 kg/h. The speed of the engine is 4000 rpm, Considering the effective stroke, calculate the scavenging ratio, the scavenging efficiency and the trapping efficiency.

3 litters, 4 cylinders engine, multipoint port fuel injection, one for each cylinder. AF ratio is 14.6, the volumetric efficiency is 90%. The engine speed at idle condition is 550 rpm with stoichiometric gasoline and inlet pressure is 30 kPa. But the engine speed is 5900 rpm with stoichiometric gasoline of maximum power, the inlet pressure is 101 kPa. Calculate the following: a. mass air flow rate in one cylinder at maximum speed, b. mass fuel flow rate into one cylinder through an injector, c. mass air flow into one cylinder at idle speed, d. mass fuel flow rate into one cylinder at idle speed, e. injection pulse duration is seconds at idle conditions at idle, f. injection pulse duration is degrees of engine rotation at idle conditions.
Q.13 An automobile carburettor having its flost chamber vented to the atmosphere is tested at sea level conditions in the factory without air cleaner. The main metering system of this carburettor is found to yield a fuel-air ratio of 0.065. The venturi throat pressure is 0.85 bar. The carburettor is now installed in an automobile and air cleaner is placed on the inlet to carburettor. The air flow rate with or without air filter is 230 kg/hr. The pressure drop through the filter is found to be 0.035 bar at sea level conditions. Issuming 7 0und orifice cocfficient to be constant calculate: The venturi throat pressure with air cleaner.

What is the injection duration (deg) needed for fuel injection in a single cylinder diesel engineoperating at 1450 rpm so that the engine produces 52 kW? The engine bsfc is 0.25 kg/kWh. Assumeincompressible fuel flow, an average cylinder pressure of 60 bar during the fuel injection, an injector effectivearea ?f = 1.5 mm2, and an injection pressure equal to 560 bar.
An engine working with injection system having the following specifications Injection pressure = 4000 kPa. Injection duration = 15 milliseconds. Penetration length 20 cm. Discharge coefficient = 0.75. The cylinder pressure at time of injection = 2500 kPa. Fuel density = 700 kg/m3. The fuel pump had to be replaced with new one. The new pumnp pressure is 6000 kPa injecting at cylinder pressure 3000 kPa.T using new set of injectors with CD = 0.8 and fuel with density = 800 kg/m3. milliseconds. The new injection duration must be set to Keeping all other parameters constant, as fuel is changed to higher density types, the injection duration must be Keeping all other parameters constant, as Cd value increases, the injection duration must be

I only need help with filling in the answers for parts h and i. At the beginning of the compression process of an air standard Otto cycle, p1 = 1 bar, T1 = 300 K. The maximum temperature in the cycle is 2250 K and the compression ratio is 9.8. The engine has 4 cylinders and an engine displacement of Vd = 2.1 L. Determine per cylinder: a) the volume at state 1.b) the air mass per cycle.c) the heat addition per cycle, in kJ.d) the heat rejection per cycle, in kJ.e) the net work per cycle, in kJ.f) the thermal efficiency in %.g) the mean effective pressure, in bar.h) Develop a full exergy accounting per cycle, in kJ. Let T0 = 300 K, p0 = 1 bar (See image below).i) Devise and evaluate the exergetic efficiency for the cycle. part h
