Gas mass flow sensors for: Automotive Commercial vehicle engines Large engines truckflow made by systec

Gas Mass Flow Measuring in Combustion Engines Simple ideas are often the best ideas Truckflow applies the principle of differential pressure. Flow measurements according to the principle of differential pressure have been used in the industry since the 19th century. They provide a number of decisive benefits, which makes them particularly attractive for use with engines: TFI4 multivariable sensor platform on aluminum venturi Without the precise control of air and EGR flows it would not be possible for the engines of modern passenger car and commercial vehicles to fulfil the strict exhaust...

Primary elements Optimal flow measurements are only possible with carefully designed primary elements. The requirements regarding primary elements should not be underestimated. In contrast to industrial primary elements completely different requirements and challenges occur with engines: Pulsation, contamination, unsteady operation, high dynamics requirements, reduced intake conditions, pressure loss, etc. systec Controls has more than a decade of experiences with the optimization of primary elements. We are happy to support you throughout the complete design process. We check the intake...

Sooting test with coated Truckflow pitot tube High-temperature non-stick coating on stainless steel pitot tube Truckflow primary elements The function and design of classical primary elements such as orifice plates, venturis and nozzles are described in standard ISO 5167. It also includes information on accuracies and correct deployment. ISO 5167 is not sufficient in the automotive field, though. The standard does not document the special requirements in the automotive field: Transient operation with strong pulsations, smaller designs and shorter intake lengths, non-round pipe geometries,...

TFI4 multivariable sensor platform TFI4 flange version venturi after environmental testing TFI4 – more than 20 years of development on just under 7cm² The TFI4 sensor platform has been optimized completely for automotive use. Ultrafast and finely calibrated sensors provide the highest measuring accuracy at the engine. With sampling rates of more than 4 kHz TFI4 manages to separate pressure pulsations from flow pulsations, thus achieving accuracies in applications close to the cylinder, that could only be achieved with test benches technology up to now. As a CAN sensor TFI4 not only provides...

Where do you have to measure? The potential deployments of Truckflow gas mass flow measurements are just as varied as the engine and control concepts. Regardless of whether you want to measure air before or after the compressor, before or after the intercooler, at a two-stage turbocharger, cold or hot EGR, exhaust gas streams or even natural gas in your bi-fuel engine – find your solution together with us. 1. Air before turbocharger At this measuring position both Truckflow pitot tubes and venturis with TFI4 analysis can be used. The calibration of the flow measurement depends on the inlet...
