Engine UMP 4216. Ulyanovsk motor plant: engines for the "Gazelle"

Ulyanovsk Motor Plant, or UMP, is known for producing engines for commercial vehicles. Let's briefly go through the history of this enterprise. The history of this plant is safely stored in the memory of many of those who have devoted their lives to the production of engines.

How did it all start?

And it all began in the autumn of 1941. It was then that a part of the Moscow Automobile Plant's production moved to Ulyanovsk. Stalin. In early November, whole echelons loaded with equipment, as well as the most important personnel, began to arrive actively in the city. The shops were set up in the shortest possible time, and the production of the plant was mainly aimed at creating equipment for the work on the fronts. In April 1942, in the walls of the workshops, the first combat vehicle was assembled and delivered. Also at the factory, imported cars were assembled. Then in the fall of 1942 the factory began to produce the first water-cooled engines. They were used during the war as generators. After the plant completely moved from assembling cars and military equipment to the production of such small-displacement engines.

On July 31, 1968, under the orders of the USSR Ministry of the USSR, the plant was renamed into UMP. The enterprise has begun work on development of manufacture of engines for cars. Then, in November 1992, the plant was transformed into a joint stock company that manufactured engines for GAZ cars. Five years later the plant successfully engaged in the production of engines for "GAZel".

Since 2005, the engine for Gazelle is the main production of the plant. And after introduction of innovations each car works on the motor from UMP.

Current trends

Today, the Ulyanovsk Motor Plant is engaged in the fact that it gradually reduces the cost of its engines, and is also actively engaged in improving the quality of internal combustion engines of its own production. Due to the fact that the company has processed many technological processes, appropriate decisions were made to introduce new principles for the manufacture of units. So, these principles and the new strategy have led to the fact that since 2009 the prices for products have decreased, and the quality of the engines has slightly increased. Now, thanks to an audit involving European independent experts, the plant's products have a truly high quality and comply with international standards.

Towards perfection

The main focus of the plant is on the supply of engines that are most adapted for "Gazelle" and "Sable", as well as for other cars based on these vehicles. UMP produces engines that meet all the necessary standards of the Euro-3 standard. The main task for the plant's employees today is an even higher quality, which the engine can have, to the Gazelle being installed.

To improve the quality of products at the plant, on the advice of third-party specialists and GAZ employees, measures were taken to improve the quality of products. In the course of this program, the plant changed suppliers of some parts and parts, introduced quality control at each stage of production, reduced the level of defectiveness of specific units and products as a whole. The cooperation of GAZ and the motor plant made it possible to significantly increase the products used on the Gazelle. The design of engines is constantly making significant changes that are designed to make the engine work flawless.

The plants have a section called the laboratory where the engines are tested. Here, the motors undergo quality assessment according to current world standards. From the whole batch of products, employees select one UMZ engine, and then install the motor on a test bench. Oil and coolants are diluted with additives, and then the engine is twisted in every way in the most severe modes. Further, after such tests, it is radiographed by ultraviolet, in which all the excretions are visible. Then the ICE is opened, during which the situation with the quality of the surfaces of parts or assemblies becomes clear. A defect is carried out, and then the elimination of defects.

«Gazel-Business»

Works on the creation of this car were launched in 2008. Engineers and marketers did a great job, a lot of research was carried out, during which they revealed future consumers, a list of spare parts. About 150 different changes were made to the design of the basic model. The main components and critical nodes in the new machine are the details of the production of foreign enterprises. "Gazel-Business" passed all the tests.

Externally, compared with the basic version, the "Business" model has not changed much. But inside and in the salon a lot has changed.

Outside, it is distinguished by another impactor with a radiator grille. The bumper is fixed on the cockpit. In previous versions, it was mounted on a frame. This allowed to significantly reduce the gap between the cab and the bumper. Slightly changed the design of the rear lights. Exterior changes include a new logo.

As for the internal content, everything is new here. This is a German-made dashboard, a new steering wheel equipped with multimedia control buttons. Everything is very modern, stylish. The cabin is decorated in silver. Also, Gazel-Business is equipped with climate control and a new on-board computer. We can say that the salon has changed completely.

Before the creation of this version, the engineers of the plant conducted a survey and found out everything that the owners of "Gazelles" did not like before. It is safe to say that everyone was heard, and many shortcomings are completely corrected.

The clutch pedal is completely redesigned, and all gears are now included very easily and at ease. The car moves better and more smoothly, and the work of the checkpoint is not accompanied by vibrations or noise. This is due to the import German nodes in this checkpoint.
