Diesel generator D49

Description of diesel generator D49

D49 is a family of four-stroke medium-speed diesel engines of a modular design with a number of cylinders from 8 to 20, turbocharged, with a power from 1200 to 6000 hp. Developed for use in diesel generator sets in the USSR at the Kolomna Diesel Locomotive Plant in the early 1960s, and are still produced there.

Currently, they are the main diesel engines on any mainline and shunting diesel locomotives and some Russian-made submarines.

The design of the D49 type device differs significantly from the existing analogues (10D100 and D50). First of all, this concerns the presence of traction indicators, thanks to which the operation of the diesel engine is ideal and lasts as long as possible. It is capable of functioning “for wear and tear”. This advantage made the device very popular, especially in shipbuilding.

Today, D49 is a group of diesel engines, where each individual model is, first of all, characterized by its own distinctive number of cylinders:

• 6D49 - configuration with eight cylinders, designed for installation on a 1200 hp shunter. diesel locomotive TGM6;
• 2D49 - with 12 cylinders, designed for shunting diesel locomotives of the TEM7 series, mainline 2TE25K, PE6 energy train, modernized diesel locomotive M62;
• 5D49 is a 16-cylinder diesel engine, ideal for mainline diesel locomotives of various types and light warships. Divided into subtypes, depending on the operating power and type of equipment being serviced (1A-, 18-, 2A-5D49, 10D49);
• 1D49 - twenty cylinders with a power of 6000 hp. Designed for experienced diesel locomotives.

Technical characteristics of diesel generator D49

The unit has the following characteristics:

• power 4416 kW;
• Y-shaped structure;
• equipped with gas-pipe supercharging;
• fuel injection occurs directly into the diesel engine;
• charge air can be cooled.
