obr_110The history of TEDOM engine production in the company TEDOM a.s., Engines division continues the rich tradition of automotive production in the Liberec region.

The tradition of engine production historically follows the RAF and ŠKODA companies. The RAF Company, based in Liberec, sold its first vehicles as early as 1906. At the beginning of the First World War, it merged with the Laurin & Klement Company, today's ŠKODA Mladá Boleslav. At that time, an automobile guild was founded in the ŠKODA Plzeň Company, focusing on the production of tractors and trucks. In 1951, truck production returned to the North Bohemian region with its center in Liberec, and Jablonec nad Nisou became a center for engine production.

TEDOM a.s., Engines Division is the successor company of the Liberec Automobile Plant - LIAZ, which was founded in 1953. LIAZ underwent major technical and production development and became an internationally recognized company, which successfully exported its products to a number of countries.

In 2003, the company became part of the TEDOM holding, which had long been a major customer of LIAZ engines. The engine production is incorporated into the TEDOM holding as a separate division based in Jablonec nad Nisou. 

Development and production

The development and implementation team of experts works on the development and production of reliable modern engines for mobile and stationary use. 


The development department itself, equipped with state-of-the-art technology for measuring the technical parameters of engines, including the concentrations of emission gases in exhaust gases, works intensively on the short-term and long-term goals of the division. In particular, it is a matter of achieving an increase in engine efficiency and lowering the production of harmful emissions produced in the exhaust gases with regard to current and future legislative limits.

Complying increasingly strict criteria, especially economic and emissions, is also the reason why we develop engines using alternative fuels from renewable energy sources.

Production activities in the Engines division of TEDOM a.s. are supported by modern technological equipment for machining on NC and CNC machines. The constant modernization of production, its organization and modern management methods enable very efficient and high-quality production.
