Proposal: The average efficiency of a car engine or Otto-cycle engine is about 30%. There are a number of internal moving parts in an engine that are used for inlet fresh air and outlet used CO2. Although lubricated, all these moving parts cause loading on the engine directly coupled to the crankshaft. There are also a number of external parts that are coupled to the crankshaft with the use of pulleys that cause loading on the engine. This paper will cover a case study on how much power can theoretically be freed up by removing all internal and external moving parts of the engine (assuming these parts can be replaced by externally mounted electric parts all powered off a battery/alternator system).
