If you go back to the dawn of engine history, you inevitably come across Prosper L'Orange, the founderof our company. He was responsible for key developments, such as the precombustion-chamber enginedisclosed in German Patent DRP No. 230517, now recognized to have been a milestone in engine design. The precombustion-chamber paved the way for the high-speed, self-igniting diesel engine, turning itfrom a stationary monster weighing tons into a compact all-rounder. Our numerous innovations have been continuing this success story to the present day. Our declared aim is tostay one step ahead of...

The world֒s leading engine manufacturers rely on our performance and reliability. As demanding users themselves, they take flexibility, reliability and innovative strength for granted and theyexpect their business partners to share those qualities. As experienced suppliers of injection systems, we facefresh challenges every day in meeting these requirements. We have no doubt that we will also be able to find a suitable solution for you.We represent the broad range of injection technology products for off-highway applications. Our systems supplyhigh-speed and medium-speed engines with an...

Over the last few years, the main challenge to engine manufacturers has been to meet the variety of exhaustemission legislation. The main demands are lower exhaust emissions and reduced fuel consumption, increased service life and lower noise emission, all of which are supported by modern injection systems, in particular. For decades, conventional pump-line-nozzle injection systems have been favored for high-speed off-highway andmedium-speed heavy-fuel engines. The main focus is on rugged, durable systems with high injection pressures and the most accurate possible fuel metering. The...

Nowadays, new high-quality engines increasingly rely on common-rail fuel injection. L'Orange is distinguished parti-cularly by its many years of experience in developing and manufacturing such injection systems. This key technology of the future will allow further significant improvements to be achieved with regard to the four main requirements ofengine manufacturers. Fuel injection at any desired pressure can be timed to the microsecond, independently of theengines operating cycle.For the engine manufacturer, the use of the compact and powerful common-rail pump has the economic and...

The test is directly linked to the design and checks that the system is meeting its performance specifications. Test rigs specially designed and produced for injection systems are used to study the functions of the system; initial endurance runs guard against premature failure or wear.We consider complete project transparency for our customers to be a prerequisite of a trusting partnership. For theentire duration of the project there is direct contact to guarantee constant harmonization of information. In addition, the system is validated on a test engine directly at the customers...

The manufacturing process is the clearest indicator of our approach to quality. A huge range of differentprocedures is dovetailed and consistently developed. > To achieve the highest product quality, we utilize virtually all the common measuring technologies: numerically controlledinspection, surface measuring, contour measuring. For pump and nozzle elements, matching clearances are measured in the m range. Endoscopes, microscopes and testing and approval test rigs complete this important department.Our manufacture is subject to extreme requirements, and this is most clearly manifested in...
