200 l. waster tank with a turbo blower, oil separator and condenser.
This is how they loaded wood.
On cold days they had to drain water (about 200 litres!) to prevent it from freezing before sunset and fill it again in the morning.
The trial model was followed by two more vehicles (built in 1949-1950) which had a bit different appearance. They were tested in very severe conditions, it was up to -40C cold and water had to be brought from the nearest lake.
Due to heavy load on the front axle such vehicles were simply sinking on dirt roads when being fully loaded. So they built the forth model of a timber truck – NAMI-018. When its rear wheels were slipping, the front ones started to pull, taking the full load.
Timber truck NAMI-012.
NAMI-012 in 1951 during official tests.
The final model – NAMI-018 in 1953.
There also existed a model powered with liquid fuel, but only on papers though…
For numerous reasons all this work finally came to silence. Stalin died by that time, camps emptied, the ruling party changed the course. And nobody needed steam cars anymore…
The destiny of NAMI vehicles is rather sad. They didn’t even become museum exhibits as well as other numerous interesting Soviet inventions. The first steam vehicle powered with wood became the last. Nobody tried to make something similar after that.
Why did they start to make them? Probably for the country defence. If a nuclear war started, the only fuel available in the country would be logs and in such a case they would extremely need steam vehicles. But they didn’t.
England still has about two dozens of steam vehicles which became a prototype for the Soviet ones. They are taken care of and polished to shine, participate in veteran meetings.
