Experience, coupled with the necessary expertise, is crucial in developing engines that run on gaseous fuels. The demands on a gaseous-fuel engine are far different from those on a gasoline engine. There are no lubrication and cooling effects, mechanical wear is completely different. In part, injection valves and pumps must be re-engineered, and the material compositions of various components in the engine and its periphery also need redefining to optimize the drive for using gaseous fuels. IAV has been working on developing CNG and LPG drives for production vehicles since 1992. During this time, our engineers have continued to widen their particular experience with the specific demands on mechanics, operational reliability and safety as well as endurance. The infrastructure – our own CNG/LPG filling stations and the integration of gaseous fuels into IAV’s testing facilities, such as in the engine test benches – has also been built up over the years.
No less crucial are engine control and calibration. We know the peculiarities that come with CNG and LPG drives. Despite relatively wide fluctuations in the composition of gaseous fuels, for example, compromises in relation to drivability and emission behavior are not acceptable. This is where the development of intelligent software functions for controlling the engine and exacting calibration work are facing new challenges. Over the years, IAV has taken many such concepts to mass-production level. IAV’s perfected testing and validation concepts and its many years of experience in developing gaseous-fuel drives ensure that motorists get to their destination safely, reliably and without harming the environment whatever their vehicles are fueled by.
