ME359/ME359A: Internal Combustion Engines

Course Description

This course will be conducted in flipped classroom mode in which typical lectures will not be delivered in the traditional way, i.e., via physical classrooms; rather, short lectures will be available to students through videos that will be periodically made available online. Generally each video will deal with a single concept. Students are expected to view these videos of their own; the viwership data will be monitored.

Every week, one/two classes will also be held in physical classrooms, as per the need, where students can discuss their doubts, problems or any concept related to the course. Some of these physical lectures will also include problem solving sessions to explain certain key concepts. Such sessions will be anniounced in advance.

All students are expected to have gone through the video lectures before coming to the physical classroom.

Release of Video Lectures

Typically, every Friday evening, between three to seven videos will be released. Total duration (per week) of these videos will be about 60 to 90 minutes (each video will be of about 15 to 30 minutes duration).  Students are expected to view these videos of their own before coming to flipped classroom sessions.

    Course Content

    Classification of engines and construction, Fuels, Fuel-air cycle, Combustion, Effect of engine variables, Combustion chambers, Carburation and fuel injection, Knocking. Engine cooling, Friction and lubrication Supercharging. Wankel engine. Testing and performance. Pollution.

    Grading Plan

    Mid Semester Exam: 32
    End Semester Exam: 48
    Quiz/Snap test: 10 (at least one un-announced Quiz/Snap test)
    Assignments/Term paper/etc.: 9

    Attendance: No separate 'marks' for attending classes (watching videos and attending flipped classes) as it is your professional duty to attend classes/watch video lectures (Exactly like a train driver is supposed to drive, and not sit at home watching internet! OR a railway reservation clerk is supposed to open the counter at 08:00 AM and cannot say that he overslept because he was partying till 03:00 AM the previous night).

    IMPORTANT: Students attending/ watching videos less than 85% of all lectures, for no valid/approved/official reasons should expect to get one grade less than their actual standing in the class, based on their semester performance. In general too, past data clearly suggests that students who do not attend regularly tend to get lower grades anyway. Those who have doubt on this issue can come to my office and I can share the data.

    Total Semester marks: 99 marks 
    One additional mark may be given to those students who are on the borderline of a particular grade boundary, for upward movement into a higher grade, provided they have been actively involved in learning throughout the semester, attending regularly and I am satisfied that a higher grade is indeed justified for them.

    Lecture plan

    The following topics will be broadly covered via the video lectures (Some lectures may be in live mode; this will be announced in advance). Every video lecture will cover one/two fundamental or key concept/model/design aspect.

    2. Thermodynamics
    3. Fuels and combustion calculations
    4. Equilibrium calculations
    5. Fuel chemistry and characteristics
    6. Combustion modeling in SI engines
    7. Combustion modeling in DI engines
    8. Gas exchange processes
    9. Engine lubrication
    10. Engine cooling
    11. Fuel injection system
    12. Carburetion system
    13. Engine testing and performance
