AU3023 Homologation Syllabus:
AU3023 Homologation Syllabus – Anna University Regulation 2021
COURSE OBJECTIVES:
The objective of this course is to provide the students a preliminary idea regarding some of the practices and standards followed in automobile industry for their testing and homologation.
UNIT I INTRODUCTION
Need of vehicle testing and homologation, Vehicle testing organizations, Hierarchy of testing: Individual component approval, System level approval and Whole vehicle approval. Type Approval & Conformity of Production tests, Approval for Safety systems (Active & Passive).
UNIT II ENGINE, FUEL SYSTEMS AND EMISSIONS TESTING
Laboratory testing of basic engine parameters: Measurement of BHP, IHP, Engine testing on dynamometers, different types of dynamometers hydraulic, eddy current etc., engine analyzersfor petrol and diesel engines, FIP calibrating and testing. Emission test for CO, HC, NOx, CO2, PM, etc. using exhaust gas analyzers, Spectroscopic methods, NDIR (Non Dispersive Infrared), FID (Flame Ionization Detector), chemiluminescent analyzers, Gas Chromatograph, Smoke meters. Emission testing on chassis dynamometers, Driving Cycles- USA, Japan, Euro and India. Test procedures – European driving cycles, Modified Indian Driving Cycle, SHED (Sealed Housing for. Evaporative Determination) Test on chassis dynamometers.
UNIT III NOISE VIBRATION AND HARSHNESS TESTING
Standard noise measurement methods, Noise inside and outside the vehicle, sources of vehicle noise – intake and exhaust noise, combustion noise, mechanical noise, noise from auxiliaries, wind noises, transmission noises, brake squeal, structure noise and noise control methods. Pass by Noise testing method.
UNIT IV VEHICLE PERFORMANCE TESTING
Methods for evaluating vehicle performance – energy consumption in conventional automobiles, performance, and emission and fuel economy, Operation of full load and part load conditions. Gradability test, Turning circle diameter test, Steering Impact test, Steering effort test. Road and track testing: Maximum speed and acceleration, brake testing, lane changing, handling and ride characteristics. Track testing on Multi Friction Braking Track, High Speed Track, Wet skid pad, Test slopes, External noise test track, Accelerated fatigue track, Water wade, Salt-water wade, and Gravel road and off road track, Dry handling circuit, Comfort track.
UNIT V AUTOMOBILE TESTING STANDARDS
Introduction, overview and study of testing standards like; AIS testing standards, Euro Standards, SAE standards. ISO26262 standards for functional safety of electrical and/or electronic systems in automobiles. Understanding of some AIS Standards: AIS-008 (Installation requirements of lighting and light-signaling devices for motor vehicles having more than three wheels, trailer and semi-Trailer excluding agricultural tractor and special purpose vehicles), AIS-018:2001 (Automotive Vehicles – Speed limitation Devices – Specifications), AIS-037 (Procedure for Type Approval and establishing conformity of production for safety of critical components), AIS093 (Code of practice for construction and approval of truck cabs & truck bodies), AIS-003 (Automotive Vehicles – Starting Gradeability -Method of Measurement and Requirements), AIS038 (Battery Operated Vehicles – Requirements for Construction and Functional Safety).
TOTAL :45 PERIODS
COURSE OUTCOMES:
At the end of the course, the student will be able to
1. Recall the need of vehicle testing and homologation.
2. Apply fundamental knowledge to measure the emissions and calculate the vehicle performance with reference to standard reference conditions.
3. Identify the testing procedures of evaluating the vehicle performance, road test and track test.
4. Understand standard procedures for vehicle certification and approval as per rules and regulations.
5. Interpret and understand various automotive testing standards.
