draw otto cycle Q&A Review

Why is the slope of two constant volume cycle different in the Otto cycle?

In Otto cycle, heat addition and heat rejection processes are constant volume processes. So if you draw a P-V diagram of Otto cycle, it will look like, So from the above graph you can see that both constant volume processes are being parallel to vertical axis. So form the basic mathematics anyone can tell that the slope of these processes is ,Infinity. ,Edit:, As I was receiving comments that the questioner meant the slope of constant volume processes of T-S diagram. So I decided to edit this answer and answer the original question. First of let me include the T-S diagram for an Otto cycle: As you can observe from the above graph that both heat supplied and heat rejection processes aka constant volume processes vary with temperature and entropy. But both processes have different slopes this is because the total amount of heat supplied will never be equal to the total amount of heat rejected. This loss of energy causes the variation in slopes. This loss might be in friction,heat losses etc. So the slope of heat addition process is always higher compared to the slope of heat rejection process. The difference between the value of heat supplied and heat rejected is called ,work,. Akshay Thanks.

How was your IIM Shillong interview experience?

Date, - 20/2/2020 ,Location ,- HMATC ,Mumbai ,Profile, - Mechanical Engineer with 15 months of work experience in the oil and gas industry. 2 panelists P1 and P2 aged between 45-50 P1, - First question after entering the room, how much tall you are?

Many years ago, car's engine would chug for a few seconds after the ignition was turned off. I have not seen this for a long time. What has changed?

This is called “dieseling”. The engine was still getting fuel, but not spark, and heat combined with compression was making it sort-of fire. It doesn’t run with normal power because conditions in the Otto-cycle gasoline engine aren’t optimal for this. This was fairly common on carbureted engines, especially with engine-driven fuel pumps. Carburetors have bowls where they draw the fuel before supplying it to the engine. These bowls had enough gas to do this even when fuel pump shut off, and an engine driven pump would still supply gas to the bowl as long as the motor turned over. This is a diagram of a simple carburetor. It’s from a motorcycle, but car carbs are similar. When cars started switching to electric pumps, dieseling became less of a problem, and then it disappeared completely when fuel injection became common. Dieseling can also happen on fuel injected cars, but there it is a symptom of a problem in the fuel system, such as a leaking injector.

Why is the thermal efficiency of ICE less than that of an ideal otto cycle?

This is because an ideal Otto Cycle neglects key elements of real internal combustion engine technologies that have been implemented. the ideal Otto Cycle neglects all mechanical friction. This includes piston friction, crankshaft friction, any place you have moving parts, there is friction and it is ignored the ideal Otto Cycle neglects any power draw from mechanisms that the real internal combustion engine needs to function properly. There is no belt, no crankshaft, not even an allowance for the camshaft. the ideal Otto Cycle neglects heat losses to the engine block. The only heat loss included is the heat rejection of the hot exhaust gases during the exhaust stroke the ideal Otto Cycle neglects the fact that fuel is not be fully combusted by the time the exhaust stroke begins. the ideal Otto Cycle neglects any performance adjustments necessary from an environmental standpoint. A typical set of parameters for a real internal combustion engine results in a minimisation of carbon monoxide, unburnt fuel, and oxydes of nitrogen; the set of parameters to minimise all of these is often working against one another, so it's a compromise position which is not the optimal one from an engine efficiency standpoint. These differences point to the fact that there is a wide chasm between an idealised cycle and a real-world working cycle.

Can a mechanical engineer share their struggle of getting a job?

Background: I am a student from mechanical department, PSG Tech, Coimbatore. This year the placements started with many companies lining up at the campus. The CS students started setting records with salaries up to 35 lpa, whereas we were getting offers not more than 5–6 lpa. I registered myself at the placement section with a CGPA of 9 and thought it won’t be a big deal as they were only around 7–8 nine-pointers in my class. But I was wrong. It took me a astonishing period to get placed. To give you a idea of how I was rejected: Bosch Ltd - Cleared first round and went to bangalore for the second. I gave my best in the GD and technical interview. But I don't know what the committee thought. They asked me to attend a third session which was stressful(only for me this additional stress round was conducted out of all the 60students). Result: Not selected. What amazed me was that a girl who came did not even know how to draw otto cycle but she was selected.(yes they preferred girls, out of selected students, 15 were girls and 5 were boys). TVS - Filled in the application form only to be rejected as I was not in BAJA and SAE. Anyway, they selected a girl who was also not involved in these events. Robert Bosch - Cleared written and technical interview. Then the HR asked if I was ok with programming. I said I was not much into programming and wanted core related jobs. Result: Rejected. Alstom - Cleared the written round. In the technical interview, the interviewer asked me to draw the stress-strain diagram (any mechanical engineer would know how easy a question it is). I drew the best diagram I had learnt only to have him say my diagram is wrong. Result: Rejected. Technip - Cleared the first round. But I lost interest in the company during PPT and didn't perform well in GD. Result: Rejected ABB - Cleared the first round and went to Bangalore. There I had to undergo a vigorous interview process for about 13 hrs (only my batch took so long) and I couldn't perform well in GD (at 9 pm). Result: Rejected. Caterpillar - Cleared the first round. But the company follows some shitty women empowerment motto. They used cheap tactics to reject boys. They selected 70 students from the written test - 7 girls (only 7 girls wrote the test and all were selected)and 63 boys including me. In GD, they put one girl in each group and eliminated all other boys. Very cheap and worst ethics followed by the recruiters. Asian Paints - The only company where I was rejected at first round itself (I later came to know they hire only 7pointers). Hyundai - Cleared the first round (couldn't attend the second round because I was held up with ABB). Finally, I was placed in Renault Nissan (RNTBCI) Chennai. Then I came to know that all those rejections were worth it! Yes, I was selected for R&D division at Chennai (my hometown). So what I would like you to carry home from this answer is that rejections are not just rejections. They are more than that. They are teachers who review your weaknesses. Keep marching ahead with full determination and you can achieve what you dream. Happy placements :)

What are some of the best interview questions asked for a mechanical engineering student?

Company : MDL (Mazagon Dock Limited) Questions : Q: Tell me something about yourself and your family background. me : told. Q: Which city in Nepal is attached to the border of Bihar ? me: I didn't knew (They told me it's Birganj ) Q: Give us an overview of your summer internship. What was its practical application? Try to keep it as short as possible. me: told Q: What was you B.Tech project about? Explain in detail. me: told. Q: What does MDL (company's name) do? me: It makes warships, ship buildings and offshore vessels for companies like ONGC. Q: Apart from MDL where else have you applied for? me: ONGC, NTPC, IOCL and BARC. Q: Tell me your area of interest? me: Thermodynamics and fluid mechanics (they started laughing because this was the area of interest common in more than 90% candidates they interviewed) Q: Draw the P-V and T-S diagram of otto cycle. What does 'S' in 'T-S' stands for? me: 'S' stands for entropy. Q: Out of 4 stroke and 2 stroke SI engine, which one has better fuel efficiency? What about Power efficiency? me: fuel efficiency of 4 stroke is better and power efficiency of 2 stroke is better. Q: So it's my final question. Suppose if you get selected in any of the above companies, would you prefer MDL over these companies? me: Sir both,my internship as well as my B.Tech project, were based on design and I would like to join a company which allows me to explore in this field, so I will surely join mdl because there is not much to explore in design field in the above mentioned companies. (They seem pretty satisfied with my answer) Advice : Thoroughly prepare your B.Tech Project and summer internship. It consumes about 70% of the total interview duration. Prepare Fluid mechanics, IC engines and Manufacturing for technical. Be ready with your answers for HR questions. EDIT: I was selected.

What is the relation between an otto cycle, diesel cycle and dual cycle?

During the working stroke in Otto cycle pressure of the gas rises at constant volume, in diesel cycle volume rises at constant pressure, and in duel cycle engine some portion of working stroke is at constant volume and rest is at constant pressure. Efficiency: 1)when compared them at same heat addition and compression ratio: efficiency of Otto cycle> efficiency of duel cycle>efficiency of diesel cycle 2)when compared them at same heat addition and same maximum pressure: efficiency of diesel cycle> efficiency of duel cycle>efficiency of Otto cycle This are found by drawing P-V diagram or T-S diagram

Can you draw 4 and 2 strokes Otto and Diesel cycles (ideal and real cycles)?

Yes. Four Stroke: GAS POWER CYCLE Two Stroke: Overall: Difference between actual and theoretical Otto cycle Comparison between the three theoretical cycles
