- I felt it was a very general overview. There was not much depth into any one topic. I feel like I could have gained the same amount from searching the internet instead of going to class. Actually, in doing old exams, I found the explainations on the internet and not in the course material for some questions.» (Almost)

- I had two engines courses in my undergraduate program. One covered of the first engines course here. The other covered the mechanical design and considerations of an engine, such as piston and piston ring design, inertias, etc.» (Yes, definitely)

6. Which parts of the course were difficult/easy?

- Difficult - optical measurement methods and CFD. No easy parts, but all related to engine operating were normal.»

- In my case, don"t need to start from very basics. Most of us already had ICE course, so we have and idea what is turbocharging.» (Good)
- I think that for the future SI and CI, he should skip the whole introduction (statistics) and leave more time to explain the HCCI,PCCI, LTCI and dual fuel... » (Good)

- Would be nice to have it with more advanced engine than conventional naturally aspirated. Let"s say use turbocharging or DI, etc.» (Ok)
- Would have been good to have the downsizing lecture earlier to understand more what to do in the task. » (Good)
- The engine design assignment was good since it was interactive. I worked on it myself to get the most out of it I could. I learned some things about the relationships regarding knock. I implemented knowledge I had from my undergraduate courses to design the engine, not this one. That is a huge flaw. We cannot implement things like spray patterns and optical measurement tests in GT Power. How long should the connecting rod be in relation to the stroke? We didn"t learn basic things like that.» (Good)
- Very interesting and useful to understand the engine parameters, and also to have a first contact with GT_power.» (Very good)

- Difficult to find faults in the model and to understand whats really happening» (40-60%)
- It is annoying that you have to setup a case for each engine speed. Should just be an option to "Go from xxxx to xxxx in steps of xxx" Like the Lotus engine simulation sofware I"ve used. Also, the conventions for cam timing and event visualization are awkard. » (60-80%)
- For the second assignment we didn"t have a presentation. The task took a lot of time if u had the desire to do it properly...not finishing fast..The assistants didn"t give any general hints or how to proceed ( I mean at a general concept level..not step by step in GT-power)» (80-100%)

- Some could have been including more. » (Ok)
- sometimes not very detailed.» (Ok)
- Doesn"t caputre the movies shown in class, which is really the only motivation to go to class nowadays. If I know I can skip and still get 90% of the information why go if have other things to do? Make people write it down and pay attention, if you miss it, get the notes from a friend - that"s better than sleeping at home, or trying not to in class.» (Ok)

29. Are you satisfied with the possibilities to get help?

- Not at all, especially in the design tasks, we had to wait after finish the tutorials two weeks so we can get the NEDC cycle...waste of time which will reflect my grades for my exams...»

- The course should be called "Engine research and trends"» (Very poor)
- It can be very good if the assignment assistance would have been close to good.. Moreover,I would have had more time to play with GT-Power» (Good)
- I enjoyed it very much. It is sad that it is already over. Would be nice to take ICE super advanced.» (Very good)

32. What parts of the course should be kept to next year?

- almost all»
- I think the lectures were good»
- The gas dynamics lectures for sure as is has to do with the design.»

33. What should be changed for next year?

- Some lecturers should cooperate with each other and find out what others are presenting, because there was same information presented by different lecturers.»
- Maybe the order of the lectures a bit...the turbocharging should come before the means of optic measurements, it can be more useful to the assignments and the optic measurements are not conflicting with anything»
- Get rid of most of the computer time and replace it with lectures. Teach people how to design an engine.»

34. General comments

- Organize the design tasks and everything will be very good!»
- Very disappointed in this course. The only benefit was getting to do the engine design simulation becuase it was fun to improve the performance of the model. Things that should be included in a course called ICE Advanced should be things like the reason piston pins are offset, and why it"s beneficial to design the pistons with slight ovality at room temp to compensate for asymmetric thermal expansion. Things most people wouldn"t think about because they are so specific to engines.»
