Using dry ice to improve performance and fuel economy

ayus yan. pagka tapos mag racing, magtinda ka ng sorbetes. tamang tama sa init ng panahon ngayon dito sa pinas. ;)

nope... CO2 is the main byproduct of the combustion cycle. CO is only produced when the combustion cycle is incomplete.

i guess we're both right. CO2 is both produced by combustion and by breathing. and CO is always produced because combustion process can't be perfect.

cold engine runs more efficient? so bakit nilalagyan ng thermostat ang cooling system para mas madali uminit ang makina? baliktad yata?

cold air intakes and intercoolers work since cold air is denser than warm air, and therefore has more mass. more mass means more oxygen for combustion, and that is also why your cars run better in the early morning, because the air is still cool >more dense >more mass >more oxygen.

DO NOT CONFUSE THIS COLD AIR AT SEA LEVEL WITH COLD AIR AT HIGH ALTITUDES! air is cold at high altitudes because it is less dense, and therefore retains heat less than dense air at sea level/low altitudes. so even if air in Baguio city is cool, your car engine runs with less power up there because the air is thin > less mass > less oxygen.

but a cold engine running more efficiently than a hot engine? naaaah! not in any book i know. the only reason there is a cooling system in your car is so that the metal parts do not break from heat induced stresses. the hotter it gets the more efficient the combustion process becomes. ever heard of ceramic engines? no cooling system, designed to run at the highest temperatures, more efficient than any cooling system equipped engine ever built.
