Gas quality measurement for natural gas vehicles

The quality of natural gas fluctuates, depending on where and when you fill up your vehicle. Our sensor based on gasQS™ technology compensates for this factor and enables the operation of more efficient natural gas engines with fewer emissions.

Natural gas vehicles (NGV) have the advantage over petrol or diesel vehicles in relation to CO2 and pollutant emissions. The planned CO2 limit values for passenger vehicles and light utility vehicles mean that low-carbon fuels such as natural gas/biogas will become even more important.

However, gas quality can vary considerably, depending on location and timing. These fluctuations will increase further with the injection of biogas and hydrogen into the natural gas network (power to gas). The gas quality sensor based on gasQS technology, which we have developed as part of the European InGas project, continuously determines the gas quality supplied to the combustion engine. The measurement occurs before the combustion process, so that appropriate engine control measures can be directly implemented.

The main parameter of our sensor is the methane number, which characterizes the anti-knock rating of a gas mixture similarly to the octane number for petrol, and enables safe operation even close to the knocking limit. Further information on heating value and Wobbe number are essential, if maximum power yield and the most efficient fuel conversion are to be ensured. Thanks to its excellent cost efficiency the sensor is suitable for mass applications, such as natural gas vehicles, for instance.
