Question Paper
Derive an expression for Thermal Efficiency of Diesel Engine.
In a Petrol Engine, the swept volume is 0·13 m^3. The temperature T1 2000 T2 977 T3 333 K and T4 681 K. The engine produces power stroke once in 2 revolutions. The engine runs at 1000 rpm. Calculate:
Heat supplied
Heat rejected
Work done (per cycle per minute)
Use Cv 713 m 0·1615 kg.
Explain the working of a 2-stroke Petrol Engine (SD with a neat sketch.
Compare the Petrol Engine (SD with Diesel Engine
What are Liquid Fuels List out their merits and demerits.
Explain the Capacitance Discharge Ignition System with a neat sketch.
What are Gaseous Fuels List their characteristics.
Explain the working of a spark plug with a neat sketch.
List out the components of water cooling system and explain about thermostat value.
Distinguish between Air cooling system and Water cooling system of IC engine.
Describe the working of Dry sump lubrication system with a neat sketch.
Describe the working of Oil pump with a neat sketch.
What are the basic measurements for evaluating performance of IC engine? How is fuel consumption measurement carried out?
Explain the basic principle and working of Proxy Brake Dynamometer.
Explain the operation of single stage reciprocating compressor with a neat sketch.
A single cylinder reciprocating air compressor running at 150 rpm delivers to a receiver 5 m^3 of free air per minute compressed to a pressure of 6 bar. The section is at 1 bar and 300° K. Compression curve follows the law pV^1.3 C and clearance is of active stroke. Calculate the volumetric efficiency and power compressor.
Explain the working of open cycle gas turbine plant with a neat sketch.
What are fuels that can be used in gas turbine power plant?
