designed for perfection

Incredible fate of the 300 series : 300 series is legendary among the diesel engines. Its history spans half a century, and begins in the pre-war forties. That's when to create new four-and six-cylinder OM 301/302. Interruption in the Nazi research was resumed after the war. The new engine of the series under the name OM 312 was introduced in 1949. It was almost identical to the basic pre-war diesels, had the same distance between the cylinders and cylinder diameter of 90 mm. The difference was in the size of the head and working stroke cylinders, increased from 95 to 120 mm. With the volume of 4.6 liter engines power output was 66 kW (90 hp).

The Series 400 : As early as the mid-1970s Mercedes-Benz began developing commercial vehicle engines which featured an intercooler in addition to the exhaust-gas turbocharger. Cooling reduces the temperature of the air compressed by the turbocharger, thus increasing the oxygen content. This permits obtaining higher power in engines with the same technical data: the OM 422 A V8 diesel developed 243 kW (330 hp) with 14.6 litres displacement, whereas its intercooler-equipped brother introduced in 1980 developed an output of 276 kW (375 hp). This OM 422 LA engine was the first commercial vehicle engine from Mercedes-Benz to have an intercooler. It was followed in 1982 by a 300 series engine, the OM 362 LA, with the same technology and an output of 141 kW (192 hp) at 2600 rpm.

Engineering department with more than three decades of experience and taking advantage of its experienced personnel in different engineering fields such as designing and prototyping of engine parts, designing different parts of production and assembly processes and testing of diesel engines, planning, preparation and installation of all production machineries, equipments and tools is ready to offer engineering services according to the needs and requirements of customers. Considering the continuous improvement of product designs by Benz Company, the engineering department of Velocity Solutions attempts to upgrade its products concordantly and we can dare say that the products of Velocity Solutions are among the modern engines of the world.

Breakthrough series 900 : In 1996 it took a radical change of heavy engines Mercedes-Benz. The debut of the 900 in the spring and backed by innovative features: electronic control, direct fuel injection with separate pumps for each of the cylinders.There were four-cylinder OM 904 LA engine of 4.3 liters producing 125 kW (170 hp) and six-cylinder OM 906 LA volume of 6.4 liters capacity reached 205 kW (279 hp). In both cases, used and pre-turbo cooler air. Maximum torque is within the reach in the range from 1200 to 1600 vol. / min. Increasing the diameter of the cylinder from 102 to 106 mm and stroke from 130 to 136 mm increased the potential of the 900. The next generation these engines are the four-cylinder OM 924 LA 4.8-liter with 160 kW (218 hp) and six-cylinder version, the volume reached 7.2 liters Power 240 kW (326 hp).
