This is an excellent question for assessing the technical expertise of a diesel mechanic candidate.
An Internal combustion engine is a heat engine where the combustion of a fuel occurs with an oxidizer air. In this engine, both the reactant and product of the combustion used as working fluid of the engine. The heat released from the combustion of fluid supplies its energy to the engine.

Job givers are looking for skillful persons in this placement. Persons have to do their best then hurry up for a nice career. Then go on for an interview with your high-end capabilities. Question 1. What Is I. Answer : The internal combustion engine converts chemical energy into useful mechanical energy by burning fuel.
Chemical energy is released when the fuel-air mixture is ignited by the spark in the combustion chamber. The gas produced in this reaction rapidly expands forcing the piston down the cylinder on the power stroke. Question 2. What Is 2-stroke Engine? Question 3. What Is 4-stroke Engine? Question 4. Answer : Octane No. It is the measure of rating of SI engine.
Cetane No. It is the measure of rating of CI engine. Question 5. Question 6. Answer : Two stroke engine is generally preferred. Because it has smaller size for the same output. Question 7. Question 8. Answer : It reduces the wear and tear of the moving parts. It damps down the vibration of the engine. It cleans the moving parts. It makes the piston gas tight. Question 9. Ether, biogas, hydrogen.
Question Answer : following are the advantages of Lubrication in IC Engine:. Answer : There are a couple of reasons why a big 4. The main reason is smoothness. A V-8 engine is much smoother because it has eight evenly spaced explosions instead of one big explosion.
Another reason is starting torque. When you start a V-8 engine, you are only driving two cylinders 1 Liter through their compression strokes, but with one big cylinder you would have to compress 4 titers instead. Answer : That is because of engine running too Lean mixture lack of fuel. This condition wilt lead to overheating and failure of the engine. Further combustion temperature of l.
Answer : For effective lubrication, lubrication oil, needs to be injected between two piston rings when piston is at bottom of stroke so that piston rides in oil during upward movement.
This way tot of lubrication oil can be saved and used properly. Thus weight of coolant gets reduced and smaller radiator can be used. Answer : The S. Both the fuels has different compression ratio. So in case of SI engine, the compression ratio is not sufficient for fuel to burn so a spark plug is used, whereas in ci engine, the compression ratio is so high that due to its internal heat the fuel is combusted so there is no need for a spark plug. So the technology used in SI engine is different from CI engine.
Answer : Diesel. Answer : In degree angle the Top ring, Second ring and Oil ring are fixed. Position the ring approximately 1 inch gap below the neck. What Is Scavenging? Answer : Scavenging is process of flushing out burnt gases from engine cylinder by introducing fresh air in the cylinder before exhaust stroke ends.
What Is Meant By Supercharging? Supercharging usually refers to belt driven compressor I. Answer : The compression ratio is high enough to combust the diesel without the aid of sparkplugs Answer Most diesel engines will have a glow plug, this gives of enough heat to help get the engine started, the heat generated from the first few revolutions together with the compression from the piston is enough to ensure the engine keeps running.
Some modern diesel engines no Longer require a glow plug. Answer : Fuel. In this technology fuel air mixture from the carburetor into the engine cylinder with a swirl action.
The advantage being one gets a more efficient burning of fuel hence more power and better fuel. Popular Interview Questions. All Interview Questions.

Lamb’s Questions and Answers on Marine Diesel Engines
This newly revised 8th edition has been completely rewritten. New coverage covers super-long-and slow-speed engines and a new generation of medium-speed engines that burn lower-quality fuels. New fuel treatment purifier systems and testing of fuel and lubricating oils on board the ship are also discussed. This Marine Diesel Engine is in its eighth revised edition and has been updated to ensure that the material is up-to-date. The ideals and precepts of the late John Lamb are considered and observed.
Ans: c. In a diesel engine, the fuel is ignited by a spark b injected fuel c heat resulting from compressing air that is supplied for combustion d ignition e combustion chamber. Ans: d. Supercharging is the process of a supplying the intake of an engine with air at a density greater than the density of the surrounding atmosphere b providing forced cooling air c injecting excess fuel for raising more load d supplying compressed air to remove combustion products fully e raising exhaust pressure. Ans: a.
Author s Stanley G. This publication is truly classic. It is widely recognized as one of the most comprehensive reference books to be used by marine engineers plus all people who seek a good working knowledge of marine diesel engines and associated equipment. This is the eight edition, which has been fully rewritten.
