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. During World War II Nazi Germany used gas vans on a large scale as an extermination method to murder inmates of asylums, Romani people, Jews, and prisoners in occupied Poland,
Exhaust manifold pressure area in the exhaust pipe, because two exhaust pulses are moving through it close in time. As the two pulses move in the exhaust pipe they should encounter either an X or H pipe. When they encounter the pipe, part of the pulse diverts into the X-H pipe which lowers the total pressure by a small amount. The reason for this decrease in pressure is that the fluid (liquid, air or gas) will travel along a pipe and when it comes at a crossing the fluid will take the path of least resistance and some will bleed off, thus
