In heavy military vehicles of the post-Soviet space, you can often find the ZMZ-41 engine. For the sixties - a high-tech product with fairly good performance. This engine showed itself well "in action", for which it received positive reviews.

History of Creation

By the middle of the last century, the line of products of the Zavolzhsky Motor Plant was morally and technically obsolete. The design of the lower engines, although distinguished by reliability, required replacement with a more modernized type. Therefore, in this period, a V-shaped engine with eight cylinders ZMZ-13 is born. It was made entirely of aluminum, which helped to reduce the weight of an already heavy engine. With a volume of 5.5 liters, this unit produced 195 horsepower. Such a high power rating was only possible with the transition to an overhead design.

After some time, the motor has been improved. The compression ratio of the fuel has increased, which led to the transition to gasoline with an octane number of 92. The cooling and lubrication system has improved. In general, the technical characteristics of the ZMZ-13 have become much better. The success of this unit was high, so it was decided to install it on a militarytechnique.

ZMZ-41 - specifications

ZMZ-13 has undergone another, now fundamental changes, so he was assigned a different index. The new engine became known as ZMZ-41. The main changes concerned the transition to cheaper A-76 fuel. Also, to reduce wear on parts, a vacuum limiter for the maximum number of revolutions was added. The compression ratio of gasoline in the cylinder now reached 6.7. All this affected the reduction in overall power. But be that as it may, the characteristics of the ZMZ-41 remained at a good level. Like the prototype, this engine has eight in-line cylinders located at an angle of 90 degrees, the volume of which is 5.5 liters. Rated power reaches 140 "horses". The maximum number of revolutions per minute is 2500. This engine is equipped with a carburetor power system, namely the K-126 model, which boasts an accelerator pump and a cold start system. Also, the device is equipped with a three-speed gearbox.

Scope of application

ZMZ-41 is mounted on military vehicles with high cross-country ability. In particular, on armored models BRDM-2. But the list doesn't end there. It can also be seen on some samples of special equipment. For example, on an experimental three-axle bonnet truck GAZ-33, which needs a powerful engine.

Pros and cons of ZMZ-41

A distinctive feature of motorsZavolzhsky plant is their good maintainability. Simple repairs can be done "on the spot" with a minimum of tools. Hence the availability of spare parts. They are cheap, and you can buy them at any specialized store. One of the main disadvantages of ZMZ-41 can be considered its non-ecological and uneconomical. Namely, high fuel consumption, especially when traveling through bad sections. But even this minus is solved on newer models by replacing the fuel supply system with an injection one. It can be found in models ZMZ-5245.
