Before revision: Electric Turbo Compound (ETC)Electric Turbo Compound (ETC)cross section Electric Turbo Compounding (ETC)is a technology solution to the challenge of improving the fuel efficiency of gas and diesel engines by recovering waste energy from the exhaust gases Raw natural gas consists primarily of methane (CH4), the shortest and lightest hydrocarbon molecule, along with various amounts of heavier hydrocarbon gases such as ethane (C2H6), propane (C3H8), normal butane (n-C4H10), isobutane (i-C4H10), pentanes and even higher-molecular-mass hydrocarbons.
