Nowwe will study PV and TS Diagram: Process 1-2: Reversible Adiabatic Compression Process; Process 2-3: Constant Pressure Heat addition; Process 3-4: Reversible Adiabatic Expansion Process Diesel Cycle is used in two-stroke and four-stroke diesel engine. The diesel cycle produces more amount of power compared with
TheGeneral Motors EMD engine line is typical of the two-stroke diesel breed. These engines were introduced in the 1930s and power a large number of the
Figure2. Indicator diagram of loop-scavenged two-stroke cycle The next event in the cycle is the inlet port closing (IPC) which takes place as the piston moves towards its TDC and covers the inlet ports. Scavenging process in a high speed two-stroke diesel engine with different bore-to-stroke ratios (a) and the respective scavenging
2 takes place from D to E. The crankshaft again revolves through 180 deg. And the piston moves back to T.D.C. ACTUAL VALVE TIMING DIAGRAM FOR FOUR STROKE CYCLE DIESEL ENGINE As we seen in the theoretical valve timing diagram, the valves open and close at the dead centre position of the piston.
Thesesteels are used in diesel engines because of their extremely high fatigue strength. It has 2.5% nickel, 0.31% carbon, 0.65% chromium, 0.5% molybdenum, and the rest is iron. This steel has a Brinell hardness of 300 BHN. #3 Chromium-molybdenum Steel. Medium- and heavy-duty petrol and diesel engines use this steel. i2z75Uw. 274 309 213 466 84 479 307 142 42
