MATLAB MODEL INPUTS AND OUTPUTS

ENGINE MODELING MINI-PROJECT ENGINE SPECIFICATIONS (10 points) Select a 4-stroke, spark ignition, naturally aspirated engine that has factory or otherwise available power and torque data. Modify a sample MatLAB engine code to represent your engine with respect to each of the following: LAMBDA TUNING (10 points) VOLUMETRIC EFFICIENCY TUNING (10 points) MBT TIMING (10 points) PERFORMANCE CURVES (10 points) FUEL CONSUMPTION MAP (10 points) EMISSIONS MAP (10 points) Paper # 2016-01-0173

ENGINE MODELING MINI-PROJECT (cont’d) ASSESSMENT OF LEARNING (15 points) Write a one-page essay about your three most valuable lessons learned as well as your two most burning questions about engine heat release modeling as a result of this assignment. ASSESSMENT OF WORK PRODUCTS (15 points) Write a one-page essay about the two greatest strengths and two greatest improvement exhibited in this project. State why the strengths are valuable in professional practice and how they were produced. Identify the added- value associated with each improvement and outline an action plan for adopting these in the future. Paper # 2016-01-0173
