AUTOMOBILE ENGINEERING BY KIRAN KUMAR.K Lecturer Mechanical Engineering Department College of Engineering and Technology Eritrea Institute of. Automobile Engineering is a vast field encompassing different types of vehicles in single notes, because vehicles are being refined and improved day by day.

It is an introduction to vehicle engineering which deals with motorcycles, cars, buses, trucks, etc.
It includes branch study of mechanical, electronic, software and safety elements. Some of the engineering attributes and disciplines that are of importance to the automotive engineer and many of the other aspects are included in it: Safety engineering: Safety engineering is the assessment of various crash scenarios and their impact on the vehicle occupants.
These are tested against very stringent governmental regulations. Some of these requirements include: seat belt and air bag functionality testing, front and side impact testing, and tests of rollover resistance. Assessments are done with various methods and tools, including Computer crash simulation typically finite element analysis , crash test dummy , and partial system sled and full vehicle crashes.
Visualization of how a car deforms in an asymmetrical crash using finite element analysis.
Emissions testing includes the measurement of vehicle emissions, including hydrocarbons, nitrogen oxides NOx , carbon monoxide CO , carbon dioxide CO2 , and evaporative emissions. NVH engineering noise, vibration, and harshness : NVH is the customer's feedback both tactile [felt] and audible [heard] from the vehicle. While sound can be interpreted as a rattle, squeal, or hot, a tactile response can be seat vibration or a buzz in the steering wheel.
This feedback is generated by components either rubbing, vibrating, or rotating.
NVH response can be classified in various ways: powertrain NVH, road noise, wind noise, component noise, and squeak and rattle. Note, there are both good and bad NVH qualities. Vehicle Electronics: Automotive electronics is an increasingly important aspect of automotive engineering. Modern vehicles employ dozens of electronic systems.
It would not be possible for automobiles to meet modern safety and fuel economy requirements without electronic controls.
Performance: Performance is a measurable and testable value of a vehicle's ability to perform in various conditions.
Performance can be considered in a wide variety of tasks, but it's generally associated with how quickly a car can accelerate e. Performance can also reflect the amount of control in inclement weather snow, ice, rain.
Shift quality: Shift quality is the driver's perception of the vehicle to an automatic transmission shift event. This is influenced by the powertrain engine , transmission , and the vehicle driveline, suspension , engine and powertrain mounts, etc.
Shift feel is both a tactile felt and audible heard response of the vehicle. Shift quality is experienced as various events: Transmission shifts are felt as an upshift at acceleration 1—2 , or a downshift maneuver in passing 4—2.
Shift engagements of the vehicle are also evaluated, as in Park to Reverse, etc. Tests include mileage accumulation, severe driving conditions, and corrosive salt baths. Drivability: Drivability is the vehicle's response to general driving conditions. Cold starts and stalls, RPM dips, idle response, launch hesitations and stumbles, and performance levels.
Cost: The cost of a vehicle program is typically split into the effect on the variable cost of the vehicle, and the up-front tooling and fixed costs associated with developing the vehicle. There are also costs associated with warranty reductions and marketing. Program timing: To some extent programs are timed with respect to the market, and also to the production schedules of the assembly plants.
Any new part in the design must support the development and manufacturing schedule of the model. Assembly feasibility: It is easy to design a module that is hard to assemble, either resulting in damaged units or poor tolerances. Quality management: Quality control is an important factor within the production process, as high quality is needed to meet customer requirements and to avoid expensive recall campaigns. The complexity of components involved in the production process requires a combination of different tools and techniques for quality control.
This standard defines the design, development, production, and when relevant, installation and service requirements. Since the s, the comprehensive business approach total quality management , TQM, helps to continuously improve the production process of automotive products and components.
Much like the Systems Engineer , the development engineer is concerned with the interactions of all systems in the complete automobile. While there are multiple components and systems in an automobile that have to function as designed, they must also work in harmony with the complete automobile. Question Papers. Question Banks.
