Thework transfer at the turbine wheel is smooth. Reduction in SFOC (Specific Fuel Oil Consumption) of 5% – 7% In down stroke, piston under side compress further the scavenge air April 30, 2014 Piston Rings – Diesel Engines; November 2, 2015 MEO Orals on Marine Electro Technology Function 5- Part 2; April 30,
TheExhaust Valve. The bigger 2-stroke marine diesel engines used for driving the propeller have a single exhaust valve which is located at the center of the cylinder head.In the earlier days this valve operated along the same lines as those used in smaller 4-stroke engines via mechanical rocker arm and spring system but it had its disadvantages in
Adiesel engine works on diesel cycle. There are four processes in diesel cycle (as shown in diagram) Diesel Cycle. Process 1-2. It is the isentropic compression of the air which is sucked in from environment. In this process work (Win) is done by the system to compress the air. Process 2-3. It is where the diesel is injected.
2stroke cycle = 2 stroke of the piston in one cycle. = One Compression stroke and One Power stroke. = Piston going up + piston going down. = One complete revolution. > Compression Stroke. When the piston goes downward exhaust valves open up and the scavenge port is uncovered which allows the fresh air to enter through the scavenge port
DieselEngine Technology. To operate effectively and safely, the engine must continuously deliver air, fuel and lubrication to the cylinders. In addition, engine emissions, created as by-products of combustion, must be treated to meet global environmental standards. While an engine can breathe in and operate on surrounding air collected through

Thelargest internal combustion engine ever built is the Wärtsilä-Sulzer RTA96-C, a 14-cylinder, 2-stroke turbocharged diesel engine that was designed to power the Emma Mærsk, the largest container ship in the world when launched in 2006. This engine has a mass of 2,300 tonnes, and when running at 102 rpm (1.7 Hz) produces over 80 MW, and
A2-stroke dirt bike engine works on two strokes or cycles of a piston. On one of the two strokes, the air-fuel mix is drawn into the combustion chamber via the transfer port from the crankcase. As the piston nears the top of the combustion chamber the spark plug ignites the air-fuel mix. This combustion creates high.
Atwo-stroke engine is a type of internal combustion engine that completes its power cycle in just two strokes of the piston, unlike a four-stroke engine, which requires four strokes. The two-stroke engine is known for its simplicity and high power-to-weight ratio, making it popular for certain applications despite its disadvantages.
Mentionthe four strokes of IC engine with a neat sketch and explain their role 5. Differentiate petrol and diesel engine 6. Mention merits and demerits of different farm power sources. 7. Differentiate IHP and BHP 8. Write about the working of four stroke cycle engine 9. Write about the working of two stroke cycle engine 10.
Theinfluence of gas intake temperature, composition and the volume concentration of each gas component on diesel engine combustion, emission and the output power was studied by building a
These4-stroke engines are used in almost every commercial as vehicles. Generally, gasoline-powered four-stroke cycles are more popular in lots of cars, trucks, etc. An operating process requires two revolutions (720°) of the crankshaft. Thus, the 4-stroke cycle completes 180° in a single stroke completing 4 strokes in 720°.
