GM-1
Sign in to saveAlso known as Göring Mischung 1
GM-1 (Göring Mischung 1) was a system for injecting nitrous oxide into aircraft engines that was used by the Luftwaffe in World War II. This increased the amount of oxygen in the fuel mixture, and thereby improved high-altitude performance. GM-1 was used on several modifications of existing fighter designs to counter the increasing performance of Allied fighters at higher altitudes.

GM-1 (Göring Mischung 1) was a system for injecting nitrous oxide into aircraft engines that was used by the Luftwaffe in World War II. This increased the amount of oxygen in the fuel mixture, and thereby improved high-altitude performance. GM-1 was used on several modifications of existing fighter designs to counter the increasing performance of Allied fighters at higher altitudes.
A different system for low-altitude boost known as MW 50 was also used, although GM-1 and MW 50 were rarely used on the same engine. MW-50 injected a methanol-water mixture into the cylinders to cool the mix. Cooling causes the air to become denser, therefore allowing more air into each cylinder for a given volume. This is the same principle that intercoolers use.
