Diesel generators of type 10D100 are in series production of the GP "Plant named after V.A. Malysheva "since 1963. During the production of diesel engines, the design, manufacturing technology and technical level of production were constantly improved, which ensured compliance of each of the modifications 10D100M, 10D100M1, 10D100M2, 10D100M1A, 10D100M1B to the requirements of world quality standards.

Design features of the diesel generator 10D100M1B:

- Cylinder liner with aerodynamic profile of scavenging windows and laser hardening of the mirror;

- upper pistons with compression rings close to the combustion chamber;

- chrome-plated compression rings with lapping of the working surface and prerabotno-exact coating disulfidmolybdenum;

- two-scraper oil-removal rings with an expander;

- normalized crankshafts with increased hardness.
[size = 13.008px] - steel-aluminum core and connecting-rod inserts with antifriction layer of AO-20 alloy; [/ size]

- fuel feed pump with a mechanical drive from the diesel;
a charge air cooler with an increased cooling surface;

- dual-mode injector;
non-junction connections of water and oil pipelines;

- shafts of fuel pumps with a modified profile.

The operation of the diesel generator 10D100M1B showed that compared to the diesel 10D100, the inter-repair runs of diesel locomotives increased by 2 times, the life before the overhaul 1.5 times; decreased fuel consumption at idle.
The modification 10D100M1B, which is now serially produced by the plant, passed a full cycle of tests and was approved according to their results. A large series of diesel generators 10D100M1B is installed on diesel locomotives and is operated by the railways of the CIS countries.

Engines of the D100 type are vertical, two-stroke, ten-cylinder, with counter-moving pistons, two crankshafts, direct-current blowdown, a two-stage pressurization system, jet spray of fuel. The engines run on liquid fuel.
Dimension: cylinder diameter 207 mm, stroke of the piston 2x254. The entry of charge air into the cylinders and the discharge of exhaust gases from them are controlled by pistons. When they approach each other (at the compression stroke), a combustion chamber is formed in the internal "dead" points between the piston bottoms and injected a sprayed diesel fuel, which ignites spontaneously.

Gases when expanding in the cylinders work, moving the pistons into the outer "dead" points, rotating the crankshafts. Thanks to the connection of the upper and lower crankshafts, their rotation is synchronized, and the power from the upper crankshaft is transmitted to the lower one, which is connected to the generator via a semi-rigid clutch. The engine and generator are mounted on a common frame.
