Question 11 A 4 stroke gasoline reciprocating internal combustion engine operating stoichiometrically in an environment at standard temperature and pressure consumes 0.8 kilograms of fuel per hour and it has a displacement of 0.77 litres. The engine speed is 2,714 revolutions per minute. Assume the ambient air density is 1.2 kg/m3. What is the volumetric efficiency of the engine. Enter your answer as a rounded percentage. e.g., if the volumetric efficiency is 63.6%, enter the number 64.
MECHANICAL VIBRATION 6.10
Show the relationship between these performance parameters and engine speed of internal combustion engine; brake power, friction power, mechanical efficiency, thermal efficiency, specific fuel consumption, brake mean effective pressure.
Specific fuel consumption of a four-stroke internal combustion engine at a given rotational speed is 0.322 kg/kW-h value is minimum. Spindle power at this rotation rate is 123 kW, volumetric efficiency is 95% and air-fuel rate is 15. The number of rotations of this engine is calculated by subtracting 1.5 from the number of rotations giving the minimum specific fuel consumption. time, spindle power 162 kW, specific fuel consumption 0.394 kg/kW-h and volumetric efficiency 85%. a) Calculate the air-fuel ratio in this case. and By what percent has the efficiency of the engine changed?
18 A single-cylinder, two-stroke cycle model airplane engine with a 7.54-cm displace ment produces 142 kW of brake power at 23,000 RPM using glow plug ignition. The square en- gine (bore stroke) uses 31.7 gm/min of castor oil-methanol-nitrome thane fuel at an air-fuel ratio AF = 4.5. During intake scavenging, 65% of the incoming air-fuel mixture gets trapped in the cylinder, while 35% of it is lost with the exhaust be fore the exhaust port closes. Combustion efficie ncy n = 0.94. Calculate: (a) Brake specific fuel consumption. [gm/kW-hr] (b) Average piston speed. [m/sec] (c) Unburned fuel exhausted to atmosphere. [gm/min] (d) Torque. [N-m]
The answer should be: Total Mech Adv ~ 6.3635; e.g., 30 x 6.3635 ~ 191 lbf out
A four-stroke, 8-cylinder diesel engine with bore and stroke of 9 inches and 12 inchesrespectively and speed of 950 RPM has a Mean Effective Pressure of 164 psi. Determine the Engine displacement ( ft^3 ) and Engine Horsepower.
Differantial Equations
During a test on a diesel engine used for driving a dc generator, the following observations were made. The engine torque is 1290 N-m running at 360 rpm. The quantity of fuel supplied to the engine was 10.8 kg/h, the calorific value of fuel being 44 MJ/kg. The air used/kg fuel is 19 kg. The exhaust gases were passed through an exhaust gas calorimeter for which the observations were as follows: Water circulated through the calorimeter = 150 gal/h, temperature rise of water is 30°C, temperature of the exhaust gases at exit from the calorimeter = 87°C, specific heat of exhaust gases = 1.04 kJ/kg-K, ambient temperature = 30°C. If the heat lost to the jacket cooling water was 94% of the brake power of the engine, draw up an energy balance sheet of the engine.
