Consider a NASCAR engine at a 2300rpm idle. The peak combustion pressure of this engine at this RPM occurs 1.5 milliseconds after the spark event. What is the ignition timing if peak pressure occurs at 9 degrees ATDC? If the inlet valve opens at 17 degrees BTDC and closes at 41 degrees ABDC calculate the inlet valve duration in crank degrees and its time open period, in seconds.

If the ignition delay of a 4 stroke diesel engine is 0.717ms at 2200 rpm, what would be the duration of the ignition delay in crank angle if the same duration in ms has to be achieved at 6000 rpm?
show step by step working for the following question for the image.
Fig.1 shows the diesel engine cycle. It is very similar to the Otto cycle (presented in thetextbook), but with two important differences. First, the fuel is not added until the air is fully compressed at point 2.This is because at the end of adiabatic compressionthe fuel begins to burn spontaneously (there are no spark plugs in a diesel engine).Second, combustion occurs more slowly and with the fuel being injected continuously.This characterizes the ignition stage as a constant pressure process. The cycle shown inFig.1 has an expansion Vmax - Vmın of 1000 cm^3and compression ratio r = Vmax/Vmın = 21.These are typical values for a diesel-powered truck. The engine operates with air intake(γ = 1, 4) at 25°C and 1 atm. The amount of fuel injected into the cylinder has a heat ofcombustion of 1000 J.a. Find the value of p, V, and T, for each of the vertices of the cycle. Finally, arrange yourresult in a table format.b. What is the total work done by the cylinder in one complete cycle?c. What…

Explain the working of two-stroke, gasoline-driven internal combustion engine?
In a six cylinder in-line two-stroke cycle Diesel engine, the cylinders are pitched 150 mm apart. The crank length is 100 mm and the ratio of connecting rod to crank is 4.5. The reciprocating mass per line is 1 kg. The engine speed is 2121 rpm. Two possible firing order for this engine are 1-5-3-6-2-4 and 1-4-5-2-3-6. As a young engineer, you have been tasked to evaluate the most suitable firing order for this engine. Your evaluation should include examination of the engine for balance of primary and secondary forces and couples for the given firing order. Apart from examining the engine, you need to justify why one firing order is superior to the other.
