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 Prototype 1 (LMP1) Class regulat...

INITIAL RESEARCH PATHWAY: WEC LMP1 POWER UNIT (POSRCHE 919, 2017) 919's 2.0-litre V4 turbo engine The Porsche 919 Hybrid at the IAA 2017  Initial Research Pathway, 2017 Porsche 919 LMP1 Car (Power Unit) Acronyms used in our report: LMP1: Le Mans Prototype 1 WEC: World Endurance Championship We specifically chose the 2017 Porsche 919 LMP1’s power unit as it was Porsche’s last hurrah in its bid for the LMP1 class of the WEC. The 919 Hybrid was immensely successful, winning 3 out of the 4 manufacturers' championships from 2014 to 2017. Firstly, we employed gAI (chatGPT) to obtain an overview of the Porsche 919’s hybrid power unit. We used the prompt, "WEC LMP1 Power Unit (Porsche 919, 2017)", which gave us a broad range of interesting and useful facts and information about the engine. We then conducted our own research and looked through various websites on google to gather more key information.  We watched youtube videos on the Porsche 919 Hybrid called, "The AMAZ...

  Brad Franklin Blackstone Singapore Institute of Technology 537 Clementi Rd Singapore 599493 Dear Professor Blackstone, I am writing to formally introduce myself to you, as a student of your Critical Thinking and Communication class. I have a Diploma in Marine and Offshore Technology, from Ngee Ann Polytechnic. I have always found engineering interesting, as it is the basis of the inner workings, and intricate details of everything around us. Starting from a young age, I have always been a hands-on individual, so taking apart structures or machines sparked my interest in design and engineering. I would say my ability to pick up on body language, tone, and demeaner, gives me an advantage when conversing with others. It provides me with the crucial understanding of which direction the conversation should go, or if the conversation should be swayed a certain way. I personally think this makes me a good mediator. Although I have an empathetic thought process, I personally t...

“I contend that we (engineers) are undervalued because of our widespread inability to explain what we do to the general public (and why it is so important). It is one of the hardest goals to accomplish, to be able to boil down difficult concepts into a short and easily understood presentation or elevator pitch.” Marybeth Miceli, President, Miceli Infrastructure Consulting, USA (2011) To the general public, when they think of engineering, they think of individuals who are more reserved, and are constantly on their computers crunching numbers, or have the impression that engineers are individuals who didn't make the cut for more glamorous jobs. Regardless of whether there's truth in those statements, I feel like engineers in general may have the brains to solve an engineering problem but may not be able to sell themselves or their ideas well. The lack of self-expression and communication will lead to their jobs being undervalued.
