Ryan's Uni Szn

At the start of this module, my primary goals were to make more informed and rational decisions through critical thinking, and to embrace the processes of learning, unlearning, and relearning. Overall, I believe I made significant progress toward achieving these goals, although there is still room for improvement. For the reader’s response report, where I wrote about Porsche’s engine, I was deeply passionate about the topic—perhaps too passionate. I ended up writing the report the way I wanted it to be and how I thought it should be, which caused me to stray from the actual requirements of the task. This experience ties closely to the concepts of unlearning and relearning. I need to recognize and unlearn the tendency to let enthusiasm overshadow focus. Passion for a subject is important, but if the energy and effort are not directed appropriately, the results may not reflect the effort invested.  I’ve also realized that everyone’s ideal outcome differs. The goal isn’t to achie...

 

1) Served as the team scribe, taking minutes during every meeting, documenting progress, and providing structure to our discussions. Ensured the team stayed on track by recording key points for re-evaluation and validating the feasibility of brainstormed solutions. 2) Proposed the idea of enhancing motor vehicle safety through advanced torque vectoring capabilities. This idea was developed through a combination of online research using Google and reviewing technical articles on automotive stability systems. 3) Suggested improvements for semi-truck braking systems to address overheating and failure on long downhill slopes. This was informed by researching articles and case studies on heavy vehicle braking performance, material science, and safety standards, primarily through Google. 4) Conducted research on the dangers faced by mountain bikers in Singapore and globally. Utilized Google searches, relevant news articles, and YouTube videos to gather insights on safety challenges specific ...

The 2017 Porsche 919’s power unit (9R9) consists of a directly injected, turbocharged two-litre V4 internal combustion engine (ICE) producing just under 500 horsepower, and two different energy recovery systems (ERS) (Newsroom 2017). The front axle mounted ERS converts kinetic energy under braking, while the rear axle mounted ERS converts energy from exhaust gases. Recuperated energy is stored in a liquid-cooled lithium-ion battery, which powers an electric motor capable of outputting over 400 horsepower, giving the 919 a combined total of over 900 horsepower. The 919 is predominantly rear wheel drive via ICE, but momentarily transforms into an all-wheel drive under acceleration, with the electric motor providing instant torque to the front axle. According to Andreani (2024), the 9R9 is Porsche’s most efficient hybrid race car engine to date. Without hybrid systems, an upwards of 20% increase in fuel consumption will be observed. Adhering to the Le Mans Prototyp...
