  • Are internal combustion engines more efficient on cold days?

    29/01/2015· $begingroup$ Efficiency aside, the cold air is denser and hence contains more oxygen per unit of volume. On engine without turbo compressor, more oxygen swallowed by the piston mean you can inject more fuel per cycle (and still get it all to react with the oxygen). This allows you to get more "oompf" from your engine at colder temperature, but as the answers here tends to demonstrate, it is
