Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

• Clutches, torque converters, and differentials
• Manual and automatic gearboxes.
• The common typologies of suspensions and steering systems.
• Different typologies of traditional and hybrid powertrains and their underlying engineering principles.

Full CEng Programme Level Learning Outcomes

Having successfully completed this module you will be able to:

• Students must use their fundamental knowledge of powertrain to investigate new and emerging technologies in automotive chassis and powertrain design. As part of the student assignment, a comprehensive knowledge of mathematics, statistics, and engineering principles would be harnessed to address, for example, the complexities of manual gearbox design by optimising gear ratios, considering torque distribution, and minimising energy losses, while integrating data from real-world testing and simulations. Their solutions would be informed by up-to-date research and an awareness of the broader engineering landscape.
• In the Chassis vibration assignment, students analyse the chassis as a complex interconnected system, considering how various components including suspension and tires influence vibration characteristics. Students employ engineering principles, mathematical modelling, and simulations to optimise the entire system for reduced vibrations and improved ride comfort, recognising interdependencies among elements.
• In the Chassis vibration assignment, students employ mathematics, statistics, and engineering principles to tackle chassis dynamics and vibration control intricacies. They use advanced mathematical models to predict and analyse vibrations, validating with statistical methods. Solutions align with cutting-edge chassis design, shaped by current research and emerging engineering trends.

Partial CEng Programme Level Learning Outcomes

Having successfully completed this module you will be able to:

• Students quantitatively analyse and assess vehicle performance, handling, and ride using mathematics, statistics and engineering principles. For example, analysis of suspension kinematics predicts pitch motion using anti-dive and anti-lift coefficients and reveals the trade-off when optimising for braking verses acceleration. The knowledge is assessed via a final written examination.
• As part of the assignment students are expected to look for sources of information other than what is presented to them in lectures and evaluate technical literature in order to address a complex problem of designing a manual gearbox.
• Students produce an efficient design of a manual gearbox that generates less pollution. Students compare various types of transmission systems and evaluate their societal and environmental impacts. Tyre design is discussed in terms of the competing demands of performance, noise, fuel economy, and end-of-use environmental impact.
