Emphasis is on gasoline and diesel, spark-ignition and compression-ignition combustion engines, though the same fundamentals may be applied to other fuels or combustion types. Introductory material is included on aspects that are related to emissions, including regulatory standards, gasoline and diesel engine basics, fuels, lubricants, combustion, instrumentation, and formation of pollutants. Several causes of emissions and pollutants are intertwined throughout the various topics and the control and treatment of specific emissions species are discussed by device type. ### requirements text Graduate/professional standing ### credit offering ids None recorded. ### llm job id enrich-8b774950c2b6adfdc46d1b82 ### llm output id 3381a405d239825f067c8e192d36b78664cd6678a5144c0f77cc4b78db3fc607 ### llm model nvidia/Qwen3.6-35B-A3B-NVFP4 ### llm model revision 1355db6a052410cfd62085d94b58866fd0f2c3c5 ### llm task version 14 ### llm search status valid ### llm summary EPD 635 covers the science and engineering design of automotive exhaust aftertreatment systems, including catalysts and emissions control. ### llm topics * Gasoline and diesel combustion engines * Emissions and regulatory standards * Formation of pollutants * Fuels, lubricants, and instrumentation ### llm skills * Design of exhaust aftertreatment systems * Control and treatment of specific emissions species ### llm assumed background None recorded. ### llm search phrases * exhaust aftertreatment catalyst design * automotive emissions control systems * gasoline diesel engine fundamentals * pollutant formation and treatment ### llm requirements status valid ### llm student summary status valid ### llm experience status insufficient\_evidence ### catalog variants None recorded. ### student summary #### context hash 04e6d667b687427271a011da54ca26bcd56783f935418d90bdffd01b7c3f6b21 #### course id EPD 635 #### current instructors None recorded. #### difficulty workload None recorded. #### errors None recorded. #### historical context None recorded. #### message No course-specific reviews available #### offered false #### profile hash 5cb4dabf887cdbcd8c00d5a1312e10828b95c63f30bc3ea76aea199565390d02 #### quick take None recorded. #### student experience None recorded. #### task hash 74fb0997943e888960bbc9e47db8c4fd12e4292d55c20509d8d89db6a9910f68 #### teaching history None recorded. #### term id 1272 #### term name 2026 Fall #### version 2 ### requirements #### nodes ```json [ { "children": [], "condition": "Graduate/professional standing", "course": null, "evidence": "Graduate/professional standing", "id": "n0", "kind": "condition" } ] ``` #### notes None recorded. #### root n0 #### status parsed ### instructors None recorded. ### offerings None recorded. ### sections None recorded. ### grade instructors ```json [ { "instructor_uid": "instructor_5a0954a22e162dcf027f7d39", "source": "madgrades", "source_instructor_id": "212004", "identity_basis": "source_id", "identity_status": "source_identified", "name": "JOHN KASAB", "email": null, "first_observed_at": "2026-09-06 23:14:58.172943+00:00", "last_observed_at": "2026-09-07 15:55:43.033547+00:00", "grade_statistics": { "gpa": null, "graded": 0, "counts": [ 0, 0, 0, 0, 0, 0, 0 ], "sections": 1 }, "instructor_url": "/instructors/JOHN_KASAB" }, { "instructor_uid": "instructor_f260033547de276c92ee3870", "source": "madgrades", "source_instructor_id": "488239", "identity_basis": "source_id", "identity_status": "source_identified", "name": "ANDREA STRZELEC", "email": null, "first_observed_at": "2026-09-06 23:14:58.172943+00:00", "last_observed_at": "2026-09-07 15:55:43.033547+00:00", "grade_statistics": { "gpa": 3.244, "graded": 41, "counts": [ 11, 12, 10, 6, 1, 0, 1 ], "sections": 6 }, "instructor_url": "/instructors/ANDREA_STRZELEC--instructor_f260033547de276c92ee3870" } ] ``` ### grades ```json [ { "run_id": "20260907T155543-ce3781c4", "semester": "1272", "observed_at": "2026-09-07 15:55:43.033547+00:00", "course_id": "EPD 635", "course_uid": "course_48b97d7c6bdc203bcadb37b8", "term_id": "1234", "term_name": "Spring 2023", "instructors": [ "ANDREA STRZELEC", "JOHN KASAB" ], "a": 0, "ab": 0, "b": 0, "bc": 0, "c": 0, "d": 0, "f": 0, "satisfactory": 0, "unsatisfactory": 0, "credit": 0, "no_credit": 0, "passed": 0, "incomplete": 0, "no_work": 0, "not_reported": 0, "other": 0, "total": 0, "source_aliases": [ "EPD 635" ] } ] ``` ### statistics #### graded 0 #### counts * 0 * 0 * 0 * 0 * 0 * 0 * 0 ### grade conflicts None recorded. ### evidence #### history * [/data/e243353dcb7d79b7247ced91d69443ef4c2a6349/history/course\_48b97d7c6bdc203bcadb37b8-0.json](https://uwcourses.com/data/e243353dcb7d79b7247ced91d69443ef4c2a6349/history/course_48b97d7c6bdc203bcadb37b8-0.json) #### traces * [/data/e243353dcb7d79b7247ced91d69443ef4c2a6349/traces/course\_48b97d7c6bdc203bcadb37b8-0.json](https://uwcourses.com/data/e243353dcb7d79b7247ced91d69443ef4c2a6349/traces/course_48b97d7c6bdc203bcadb37b8-0.json) #### results * [/data/e243353dcb7d79b7247ced91d69443ef4c2a6349/results/course\_48b97d7c6bdc203bcadb37b8-0.json](https://uwcourses.com/data/e243353dcb7d79b7247ced91d69443ef4c2a6349/results/course_48b97d7c6bdc203bcadb37b8-0.json) ### revision e243353dcb7d79b7247ced91d69443ef4c2a6349 ## instructor Trends None recorded. ## following None recorded.
