Gas van Gas van A gas van or gas wagon ( ("dushegubka"); ) was a vehicle reequipped as a mobile gas chamber. The vehicle had an air-tight compartment for the murdered victims, into which exhaust fumes were transmitted while the engine was running. The murdered victims were gassed with carbon monoxide, resulting in death by carbon monoxide poisoning and suffocation. The gas van was used by the Soviet secret police in 1930s.

Exhaust gas the European Union's man-made CO emissions, with passenger cars contributing about 12%. European emission standards limit the CO emissions of new passenger cars and light vehicles. The European Union average new car CO emissions figure dropped by 5.4% in the year to the first quarter of 2010, down to 145.6 g/km. Vehicle exhaust contains much water vapour. There has been research into ways that troops in deserts can recover drinkable water from their vehicles' exhaust gases. Emission standards focus on reducing pollutants contained in the exhaust gases from vehicles as well as from industrial flue gas stacks and other air
