Hatz

Hatz, also known as Motorenfabrik Hatz, is a German manufacturer of industrial diesel engines headquartered in Ruhstorf an der Rott in Lower Bavaria. The company traces its origins to 1880, when it was founded by Mathias Hatz, although engine production began later, in 1904. Its historical specialization has been the development of compact, durable and comparatively lightweight diesel engines for equipment in which small dimensions, low mass, dependable operation and straightforward maintenance are important. The company initially developed engines for stationary applications. In 1910 it began producing hot-bulb engines, and this work led to the development of its first water-cooled diesel engine, the H-series. Hatz expanded its production base at its present location during the early twentieth century and began exporting to South America. During the 1930s it also developed engines intended specifically for construction-related applications, including the horizontally configured L2 two-stroke engine. After the Second World War, Hatz broadened its industrial reach. It presented agricultural tractors in 1950 and introduced the E80, its first air-cooled four-stroke diesel engine, in 1953. The E80 was marketed internationally. The later E75, introduced from 1958, was a particularly important product because its light-alloy housing, low weight and high rotational speed demonstrated the advantages that became closely associated with the Hatz brand. In 1966, Hatz introduced the E671, described in the reference material as the world's smallest industrial diesel engine at the time. These developments reinforced the company's position in compact engine technology. Noise reduction became another area of differentiation. Hatz introduced the SilentPack, a capsule for air-cooled engines, in 1978. The system was intended to reduce noise emissions substantially compared with an uncapsulated engine, helping make compact diesel power more suitable for equipment used in urban, indoor or noise-sensitive environments. The company also continued to develop engines for construction machinery, including compactors and other small machines. Hatz's modern engine portfolio has included several air-cooled series and, from 2014, a new water-cooled H-series. The B-series is centered on compact single-cylinder engines in horizontal- and vertical-crankshaft configurations. The D-series, also called SUPRA, emphasizes smooth running and robust operation for applications such as compaction equipment and generator sets. The G-series consists of compact two-cylinder engines. The higher-output M- and L-series cover two-, three- and four-cylinder air-cooled engines, with the L-series incorporating the SilentPack concept. The H-series added a water-cooled four-cylinder engine using common-rail injection, turbocharging and external exhaust-gas recirculation. In addition to complete engines, Hatz operates through systems and components activities. Hatz Systems develops generator sets, pumping systems, scalable power and energy solutions, marine propulsion products and special-purpose systems, including customer-specific applications. Hatz Components manufactures precision parts such as connecting rods, crankshafts, housings and other rotating or control elements for vehicle, agricultural, motorcycle, printing, racing and energy-generation industries. The company has also undertaken contract manufacturing of automotive components since the late 1980s. Hatz engines are mainly associated with small construction machinery, generators and pumps, but the company's products have also been used in agricultural, commercial-vehicle, maritime, military and specialist applications. Their compact format has enabled unusual applications as well, including installation of a Hatz single-cylinder engine in a motorcycle conversion. Overall, the brand's positioning rests on compact industrial power, durability, serviceability, low weight, noise-control options and compliance with…

Hatz was founded in 1880 by Mathias Hatz in Germany. The company began building engines in 1904 and initially concentrated on stationary power. In 1910 it started producing hot-bulb engines. From this engineering base, Hatz developed its first water-cooled diesel engine, the H-series, with a design intended for reliable stationary operation. During the early twentieth century, the company established a plant at its present site in Ruhstorf an der Rott and began exporting engines to South America. In the 1930s Hatz increasingly addressed the needs of construction equipment. Its L2 two-stroke engine, developed in 1936 with a horizontal cylinder arrangement, was designed for construction-industry use. Following the war, the company presented agricultural tractors in 1950 and introduced the E80 air-cooled four-stroke diesel engine in 1953. The E80 was sold internationally and helped broaden Hatz's market presence beyond stationary equipment. The E75, produced from 1958, became an important demonstration of Hatz's compact-engine philosophy. Its light-alloy housing and low weight enabled high rotational speed in a small package. In 1966 Hatz introduced the E671, described in the available reference material as the world's smallest industrial diesel engine at that time. The company continued to develop small diesel engines and, in 1978, launched the SilentPack encapsulation system. By enclosing an air-cooled engine, SilentPack was intended to reduce noise emissions by as much as 90 percent compared with a comparable uncapsulated engine. Hatz expanded beyond complete engines in 1988, beginning contract production of automotive components such as connecting rods, crankshafts and rocker arms. This activity later grew into a components business serving automotive, commercial-vehicle, agricultural, motorcycle, printing, racing and energy-related industries. Hatz's component capabilities include machining of different high-strength and lightweight materials and the manufacture of parts for applications ranging from single-cylinder engines to heavy-duty multi-cylinder systems. The company introduced the two-cylinder 2G30 in 1986 and developed the B-series during the 1990s. The B-series became a major volume platform, offering compact air-cooled single-cylinder engines with horizontal or vertical crankshafts. Hatz also developed vertical-shaft engines and supplied power units for specialist applications. Their low weight made them suitable for unusual installations, including a Hatz 1B40 engine used in a motorcycle conversion based on a Royal Enfield motorcycle. Hatz's portfolio later developed into several engine families. The B-series emphasized compactness and low mass; the D-series SUPRA added balancing technology and smooth running; the G-series provided two-cylinder air-cooled power; and the M- and L-series extended output through two-, three- and four-cylinder configurations. The L-series incorporated the SilentPack concept. Emissions legislation became increasingly important, leading to the availability of particulate filtration and exhaust-gas-recirculation solutions for higher-output engines. In 2014 Hatz introduced the water-cooled H-series, beginning with the 4H50TIC. It combined common-rail fuel injection, turbocharging and external exhaust-gas recirculation in a compact four-cylinder package. This broadened the company's offering into a higher-performance class while retaining its emphasis on low weight and integration. Alongside its engine business, Hatz Systems developed generator sets, pumping technology, marine propulsion and special applications. The company therefore evolved from a small-engine manufacturer into a broader supplier of industrial engines, power systems and precision engine components.
