The K-16 diesel engine of 4.4 cc displacement was the first model diesel to enter large-scale series production in Russia. With a bore and stroke of 16 mm and 22 mm respectively, it was a notably long-stroke design harking back to the pioneering era. However, it reflected then-evolving design thinking by featuring crankshaft front rotary valve (FRV) induction through an updraft carburettor. It displayed a number of unusual features, including the fuel tank mounted above the main bearing and the arrangements for providing a compression screw lock. 

The K-16 seems to have appeared in late 1949, remaining in production right up to the mid 1950's. Along the way, it passed through two variants, although these only differed in a few relatively minor details. It was produced in quite large numbers to very acceptable standards, becoming perhaps Russia's most widely-used model engine during the early 1950's. It enjoyed some competition success, being used to establish a number of records during that period.

A full description and bench test of this interesting engine will appear on this website in due course.
