QUESTION 1 An Automotive Engineering company has à task to setup a diesel engine for a new vehicle model. The engine has four-cylinder, four-stroke and 3 liters of displacement volume that operates on the ideal diesel cycle with a compression ratio of 17 as shown in Figure 1. The engine uses light diesel fuel with a heating value of 42,500 kJ/kg and an air-fuel ratio of 24. You are the engineer in the company is given the following task to analyze the engine characteristics based on constant specific heats at 500 K, a) Evaluate all the working temperatures and pressures al all points on P – V diagram. b) Evaluate the thermal efficiency of the cycle. c) If the engine is plan to operate at 3000 rpm, evaluate the power rating produce by the engine.

QUESTION 10 A four-cylinder, 3.6-liter, four-stroke cycles Sl engine operates at 2700 RPM with a volumetric efficiency of 87 %. The fuel used is methyl alcohol. The chemical reaction of methyl alcohol in a Stoichiometric condition is: CH3OH + 1.5(02 + 3.76N2) - CO2 + 2H20 + 1.5(3.76N2) The chemical reaction of methyl alcohol in an equivalence ratio of o = 1.23 is: CH3OH + m(02 + 3.76N2) → NCO2 + pCO + 2H20 + m(3.76N2) During combustion, all hydrogen is converted to water, and all carbon is converted to CO2 and CO. The density of standard air is 2.25 kg/m. The atomic masses are as follows: H=1, C=12, 0-16, and N=14. Calculate the following: m is n is p is Mole fraction of CO in the exhaust is The mass flow rate of air into the engine is gram/s.
18.13 A rotary compressor is used to supercharge a petrol engine. The static pressure ratio across the rotor is 2.5:1. Static inlet pressure and temperature are 0.6 bar and 5°C, respectively. The air-fuel ratio is 13:1 and the engine consumes 0.04 kg fuel/s. For the air-fuel mixture take y = 1.39 and 1.005 kJ/kg K. The isentropic efficiency of the compressor is 84%. Estimate the power required to drive the compressor. Taking the exit velocity from the compressor as 120 m/s and assuming that the mixture is adiabatically brought to rest in the engine cylinders, estimate the stagnation temperature and pressure of the mixture at the beginning of the compression stroke in the engine cylinder. с
