POWERTRAIN DESIGN AND CHASSIS ENGINEERING - 2021/2

Module Overview

Second year module for Automotive Engineering students.

POWERTRAIN DESIGN:

The fundamental concepts determining the performance of internal combustion (IC) engines are explained. The derivation of the governing equations is the starting point for describing the benefits, limits and design targets for downsizing of IC engines. The concept of turbo- and supercharging is introduced together with examples on matching of a turbo/supercharger with an engine. Hybrid and electric powertrains are introduced by describing how electrification of individual components can improve powertrain performance in terms of environmental impact, efficiency and driving characteristics.

CHASSIS ENGINEERING:

The structural requirements of vehicle chassis are introduced with respect to internal and external loads. Fundamental chassis design targets are described and the basic chassis structures and substructures are explained. Following the discussion of road loads, the underlying concepts of semi-active and active suspension systems are introduced and improvements in terms of comfort, ride and handling characteristics, together with limitations are explained. The concepts, aims and limitations of chassis control systems ABS, TC and ESP are described.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate understanding of scientific principles, methodologies and mathematics methods as well as the ability to describe particular systems and processes in the final examination. The coursework element allows students to demonstrate that they can interpret a problem, develop design targets, and present and justify a solution clearly and accurately.

 Thus, the summative assessment for this module consists of:

·         Powertrain coursework [Learning outcomes 1, 2 ]                (9 hours)     Deadline c. W5    {15%}

·         Chassis coursework [Learning outcomes 1, 2 ]                    (9 hours)     Deadline c. W10 {15%}

·         Examination               [ Learning outcomes 1, 2, 3, 4 ]          (2 hours)                      {70%}

 Formative assessment and feedback

• Formative verbal feedback is given in tutorials


• Written feedback is given on the coursework assessment

Module aims

• an introduction to the fundamental characteristics of different powertrain and chassis design solutions found in modern and future vehicles;
• an understanding of the governing equations of internal combustion engine design and the principles of the electrification of the powertrain;
• an understanding of the loads experienced by chassis structures and possibilities to enhance driving experience (ride and handling) and comfort of a vehicle.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

introduce powertrain design and chassis engineering principles through theory with worked examples. This is delivered principally through lectures, tutorial classes and a coursework element involving basic powertrain and chassis design methodologies.

The learning and teaching methods include:

• 3 hours lecture per week x 11 weeks


• 1 hour tutorial (in groups) x 11 weeks


• 2 hours revision lectures


• Powertrain coursework (9 hours) submitted on SurreyLearn


• Chassis coursework (9 hours) submitted on SurreyLearn

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
