Summary Draft #2 + Thesis (WEC LMP1 Porsche 911 Power Unit 2017) (Updated)


The 2017 Porsche 919 Hybrid LMP1 is powered by an advanced power unit with an internal combustion engine, a turbocharged 2.0-litre V4, and an electric system (Goodwin, 2017). The 2 engines combined produce a total output of over 900 HP. Fuel is directly injected into the ICE, which produces 500 HP. The rest comes from 2 energy recovery systems (ERS) that are stored in lithium-ion batteries (Brownell, 2017). The ERS-K (Kinetic) recovers almost 60% of the energy generated during the deceleration at the front wheel, which provides all-wheel drive functionality whenever necessary. The ERS-H (Heat) creates energy by utilising the heat from exhaust gases (Porsche AG, 2017).  According to Goodwin in 2017, with the regulations set by the governing body of the Le Mans 24, the racecar was allowed to consume up to 8 MJ of the energy recovered by the ERSs to cover as many laps as possible in the 24 hours of racing. This made the 919 Hybrid the most energy-efficient car on the track. 

Thesis Statement: With the combined ICE and electric engine (ERSs) in the power unit, the Porsche 919 Hybrid is among the most technologically advanced cars to dominate the WEC and Le Mans 24-hour.

My Introduction (Updated)

Dear Professor Blackstone,  My name is  Ashutosh Kumar, but you can call me Ash. I graduated from Ngee Ann Polytechnic in 2022 with a diploma in mechanical engineering. Growing up around relatives in diverse industries, my uncle, an oil engineer, sparked my love for engineering. He would explain the math and science behind his work and projects that he led, in a way a 10-year-old could grasp, which led to an interest in those subjects to pursue and do well in school. One of my communication strengths is active listening. Instead of hearing words, I tend to understand the message someone is trying to convey. During my counselling sessions, my counsellor actively listens and provides feedback on how I can improve. Understanding the value of active listening has helped me build trust and maintain meaningful relationships with friends, peers, and others.  One area I need to improve is the need for more clarity. I sometimes beat around the bush instead of getting straight to the point. As I

The importance of communication skills for future engineers (Interpretation of Quote)

 “Communication skills are an essential component in the education of engineering students to facilitate not just students’ education but also to prepare them for their future careers.” - Marc Riemer, Faculty of Engineering, Monash University (2007) To my interpretation of this quote, communication is one of the most overlooked skills any one can learn, be it an engineering student or a student from other fields of work. For engineering students, communication skills are essential as it helps to strengthen the bond between a team when taking on projects as it helps to get ideas across easily from one group member to another for example. Communication helps to solve issues where different ideas are needed. This can be done by members of the team through communicating with one another.  This in turn helps to build teamwork between them, which is also another key skill.   Engineering students are mostly bound to the technical terms they have learnt and, when they are put in a team of stud
