Developing an Engine that Repurposes Waste Energy

The fact that our engines waste our fossil fuels by only using only about 30-45% of the energy from gasoline would create an outrage among the people that want to maximize the use of out fossil fuels as they begin to run out. They would call it pure insanity. What will anger them more is that the wasted energy goes off as heat into the atmosphere. Increasing the efficiency is upsettingly and depressingly, near-impossible. What can be done is that we repurpose that heat into something useful! The best solution is to use an engine that takes this waste heat and converts it into some energy. To start, engines are all about thermodynamics. There is the heat engine, a system that converts heat into work. One such thing is the internal combustion engine in the car. There are two laws that apply to thermodynamics for which vehicle engines revolve around. The first is that energy cannot be destroyed, only converted from one to another, like how the engine converts heat into work and that to see how much has been converted, you take the energy transferred from the heat source and subtract the heat that goes to the cold sink from it. The second law is that it is impossible to create an engine that all of the heat can be converted to work because there must be some expelled heat for the engine to function. There is also the idea of the carnot efficiency that also must be discussed. Carnot efficiency is the efficiency that is the maximum of an engine. That doesn’t necessarily mean 100%! The Carnot efficiency of an average car is 58.5%, which sounds pretty low and the actual efficiency of 30-45% is even worse. There are many places where things could be fixed, including but not even close to limiting the friction, the energy required to ign... ... middle of paper ... ...e. If placed on the catalytic converter, there is technology out there designed to keep that area warm for around 32 hours! This area can be utilized to have make some extra power due to the fact that the stirling engine runs on the temperature difference and the prolonged warmth allows it to do so. Due to the conditions of both solutions, it is best to have both installed to ensure maximum performance, boosting the efficiency and mileage even more. Adding the stirling engine to the already popular hybrid technology seems a good solution and would be part of our method to maximizing the use of our fossil fuels in engines. As they begin to run out, we will have to push the idea of getting the most out of what we have left. In the future, there will be new technologies that would be added to the already growing list of innovations that takes the most out of every drop.
