Abstract This paper presents novel green automotive platinum sensing technology together with pressure sensors design principles and applications. In recent years, worldwide emissions legislation has been introduced and is rapidly becoming more stringent. With alternative vehicular propulsion methods far from becoming mainstream reality, leading automotive providers have intensified efforts in the direction of reducing the harmful footprint of their products. This is being accomplished via smaller, appropriately designed internal combustion engines, necessitating an increased and higher-performance sensor content per vehicle. This paper elaborates on temperature sensor application in automotive exhaust gas performance sensing and as well as pressure sensors in different challenging automotive applications with very high pressure levels.

Model Based

Engine exhaust backpressure is a critical parameter in the calculation of the volumetric efficiency and exhaust gas recirculation flow of an internal combustion engine. The backpressure also needs to be controlled to a presetting limit under high speed and load engine operating conditions to avoid damaging a turbocharger. In this paper, a method is developed to estimate exhaust pressure for internal combustion engines equipped with variable geometry turbochargers. The method uses a model-based approach that applies a coordinate transformation to generate a turbine map for the estimation of exhaust pressure. This estimation can substitute for an expensive pressure sensor, thus saving significant cost for production vehicles. On the other hand, for internal combustion engines that have already installed exhaust pressure sensors, this estimation can be used to generate residual signals for model-based diagnostics. Cumulative sum algorithms are applied to residuals based on multiple sensor fusion, and with the help of signal processing, the algorithms are able to detect and isolate critical failure modes of a turbocharger system.

Composite Carrier

Fibre optic strain sensors are being increasingly deployed subsea due to significant improvements in reliability and ease of deployment brought about by embedding the optical fibre within a composite carrier that simply clamps to the structure to be monitored. There is significant experience in deploying these sensors on a variety of risers by a number of different installation methods as part of project integrity management strategies. Building on experience from monitoring risers, the technology is now being applied to other subsea infrastructure including manifolds and flowlines for monitoring parameters including pressure, axial load, shape and temperature. The same technology has even been deployed downhole for measuring loads in production tubing. Two different types of instruments have been designed to meet the needs of the industry, namely single point sensors and sensors that measure the profile of parameters over an extended distance. Point sensors have been developed to measure axial load, internal pressure, curvature and temperature. Each sensor mechanically attaches to the pipeline to transfer strains and temperatures in the pipeline. The instrument has been demonstrated to detect pressure changes from quasi-static to hundreds of hertz as required for conditions such as flow induced vibration and detecting slug flow. By locating a number of pressure sensors along a flowline the onset of waxing or hydrate build-up can be detected. The flexibility of the technology enables deployment in the yard, on deck and even retrofit installation by ROV. Profile sensors have been developed to measure bending profiles of flowline buckle regions, flowline free spans and riser touchdown zones. The profile sensors are elongated instruments that cover the entire length of the flowline to be monitored. Fibre optic sensors are embedded within a composite carrier during a continuous manufacturing process such as filament winding or pultrusion. Instruments with as many as 280 embedded sensors have been manufactured and deployed to date. Instruments have been developed to measure upheaval and lateral buckling strain profiles in HPHT flowlines. Deployment methods have been developed for retrofit installation and for installation on deck. The paper will present the current status of subsea pipeline monitoring using fibre optic strain sensors including results of both point and profile sensors. In addition further applications for the technology will be discussed.
