    Diesel Exhaust: Enough Carbon Monoxide

    How do we know a diesel engine can produce enough carbon monoxide in its exhaust to kill people?

    Holocaust deniers claim:

    The idea of using diesel engine exhaust to murder some 1,400,000 Jews in the gas chambers of Treblinka, Belzec and Sobibor, the three death camps of Operation Reinhard, is “idiotic” and “simply incredible” because diesel exhaust “always” contains “less than 1% carbon monoxide,” which is not lethal.[1]

    The facts are:

    Two separate scientific studies show that it is possible to adjust a diesel engine to produce a lethal amount of carbon monoxide.  

    Friedrich Berg, an American Holocaust denier, is the author of a series of articles in which he claims that using diesel engine exhaust to kill human beings is “idiotic” and “simply incredible.”[2] Berg’s article appears technically impressive because it contains charts and graphs, leaving the average reader with the impression that his assertions are backed up by science.[3]

    The facts about Berg’s “science.”

    Two peer-reviewed scientific studies done by qualified engineers show that diesel engine exhaust can contain lethal amounts of carbon monoxide, making it possible that it could be used to murder human beings.

    The first study was conducted in 1941 by Holtz and Elliott. This study analyzed the chemical composition of exhaust from diesel engines under different running conditions.

    The second study was done in 1957 by R.E. Pattle et al. Small animals were placed in a container filled with diesel engine exhaust and studied for their reaction.

    What the 1957 study by R.E. Pattle et al found.

    In the Pattle study the exhaust from a single-cylinder diesel engine was directed into a chamber with a volume of 10 cubic meters (353 cubic feet) of air in which mice, guinea pigs, and rabbits were placed. The engine was then run for five hours in four different modes until the animals were dead, disabled, or clearly going to survive.

    In Mode A the engine was run according to the manufacturer’s specifications. The animals survived the entire five hours and recovered with no ill effects.

    In Modes B and C, the engine was slightly modified. Some of the animals died in the fourth hour of the experiment and others died several days later from severe lung damage.

    However, in Mode D, in which a metal blank was used to reduce the size of the air intake, all of the animals died in three hours and 20 minutes. Analysis of the atmosphere in Mode D showed that it contained 22 percent carbon monoxide (or 220,000 parts per 1,000,000).[5] Recall that a carbon monoxide concentration of 4/10 of one percent (.4%) or 4,000 parts per 1,000,000 parts of the atmosphere is lethal.

    What the Holocaust deniers say about the Pattle et al study.

    Berg ignores the fact that some animals died in Modes B and C and tries to explain away the importance of the finding that all of the animals in Mode D died by focusing on the fact that the deaths took longer than 30 minutes—which is what the eyewitnesses say was about the time it took to kill a small room or truck full of human beings.

    However, comparing the conditions for the animals in the Pattle study with the conditions in the gas chambers for people is comparing apples and oranges:

    First: The method of introduction of the animals into the cage and the people into the gas chambers was fundamentally different.

    The small animals in the Pattle study were healthy and not stressed when they were placed in the chamber. The Germans, however, often drove their terrified human victims at a run into the gas chambers using whips, dogs and guns. People who are panicked or panting heavily will breathe in the carbon monoxide, smoke, soot and the other toxins more quickly. They also exhale carbon dioxide that builds up in the atmosphere which further disables their ability to breathe freely. Further, many of those murdered were elderly, very young, or physically debilitated due to starvation and sickness—all of which would have affected their intake of carbon monoxide positively.[6]

    Second: The size of the box and gas chambers relative to their occupants was very unequal, making comparison between the effects on the animals in a box and people in a gas chamber irrelevant.

    In the Pattle et al study the small animals were placed in an enclosure that had a volume of 10 cubic meters (353 cubic feet) of air. In the gas chambers, hundreds of human beings were pushed tightly into a space that contained somewhere between 1,412 and 1,765 cubic feet. Their bodies alone displaced most of the air in the space and what little was left to breathe was rapidly replaced by a soup of toxic gases.

    Corroborating this conclusion is the letter that Willy Just, the foreman of the shop that made the murderous adjustments to the regular trucks to turn them into gas vans, wrote to Walther Rauff, the head of the gas van program. In it Just noted that shortening the length of the larger gas vans by three feet would mean that the space to be filled with toxic exhaust gases was smaller and the time it took to kill the victims was “considerably less.”[7]

    If, in Mode D, Pattle had put the animals into an area only an inch larger than they were, how much more quickly would they have died? We don’t know, but it is safe to assume it would have taken less than 3 hours and 20 minutes.

    How do we know adjusting the engines was a simple procedure?

    Adjusting the fuel pump or blocking the air intake does not require mechanical or engineering skills that were outside the capabilities of the SS technicians who ran the engines, as the perpetrators themselves testified.

    Erich Bauer, the “Gasmeister” (“Gas Master”) in Sobibor, specifically testified that he had “worked with motors.”

    Erich Fuchs, who also served at Sobibor, described an instance when he had to repair the engine: “We installed the engine on a concrete base and connected the exhaust to the pipeline. Then I tried the engine. It hardly worked. I repaired the ignition and the valves, and finally got the engine to start.” These repairs are more complex and skilled than making a simple adjustment of the air intake or fuel mixture on the engines.

    Further, some of the Ukrainians auxiliaries were mechanics as well.[8]

    Conclusion

    Like the Leuchter Report which purports to prove that there were no gas chambers in Auschwitz-Birkenau, Berg’s work is junk science. Murdering people using diesel engine exhaust is not “idiotic” or “simply incredible” as he claims.

    Scientific peer-reviewed studies done by qualified engineers show that animals can be overwhelmed and die from exposure to carbon monoxide in diesel engine exhaust if slight adjustments are made to the engine so that it runs outside of the manufacturer’s specifications.

    In the animal studies, some animals survived and others died after a period of several hours in relatively spacious conditions. However, in the gas chambers panicked, unhealthy human beings were crammed into a much tighter space, which was then filled with the smoky, hot, toxic exhaust from a slightly misadjusted diesel engine. In such conditions, the evidence indicates that they could be overwhelmed and die within 30 minutes, either from carbon monoxide poisoning, lack of oxygen, or both.

    Finally, the evidence indicates that the SS men and the Ukrainian auxiliaries had the ability to perform repairs or make these adjustments.
