An automotive engine has a charge air conditioning system, including a charge booster, and a first intercooler for transferring heat from charge air flowing from the booster. The first intercooler transfers heat from the charge air to ambient air, and a second intercooler downstream from the first intercooler further reduces the heat content of the charge air by transferring heat from the charge air to a refrigerated fluid. An engine control module controls the engine's spark timing and fuel charge as a function of at least the amount of air charge cooling provided by the second intercooler. The present engine is particularly well adapted to operate on gaseous hydrogen fuel.
