Abstract

Meeting EPA Tier 3 emissions reduction requirements while simultaneously increasing fuel economy to meet new CAFE standards will require optimization of advanced combustion strategies and emissions control technologies. There is an immediate need for suitable exhaust gas sensor technologies to monitor internal combustion engine tailpipe emissions and to control and maintain efficient operation of the engine and exhaust after treatment systems. NH₃, NO_x, and HC sensors could enable onboard diagnostics and combustion control in lean-burn engines, analogous to the role of O₂ sensors in stoichiometric burn engines. Commercial manufacturing methods have been used to fabricate self-heated mixed-potential sensors in a planar automotive configuration. By altering materials composition and operating conditions, we are able to obtain sensitivity/selectivity to each NH₃, NO_x and HCs. In addition, these devices exhibit stable performance over months of testing as a result of the stable morphology of the electrode/electrolyte/gas three-phase interface.

Application of commercial sensor manufacturing methods for NOx/NH3 mixed potential sensors for emissions control

Conference Brosha, Eric; Mukundan, Rangachary; Nelson, Mark; ...

The purpose of this research effort is to develop a low cost on-board Nitrogen Oxide (NO{sub x})/Ammonia (NH{sub 3}) sensor that can not only be used for emissions control but has the potential to improve efficiency through better monitoring of the combustion process and feedback control in both vehicle and stationary systems. Over the past decade, Los AJamos National Laboratory (LANL) has developed a unique class of electrochemical gas sensors for the detection of carbon monoxide, hydrocarbons, hydrogen and nitrogen oxides. These sensors are based on the mixed-potential phenomenon and are a modification of the existing automotive lambda (oxygen) sensormore »« less

Additively manufactured mixed potential electrochemical sensors for NO_x, C₃H₈, and NH₃ detection

Journal Article Tsui, Lok-kun; Benavidez, Angelica; Evans, Lindsey; ... - Progress in Additive Manufacturing

Additive manufacturing of mixed potential electrochemical sensors opens the possibility to perform rapid prototyping of electrode and electrolyte materials. We report for the first time the use of this technique for the fabrication of solid-state electrochemical gas sensors of the mixed potential type and assessment of variability in the manufacturing process. La_0.87Sr_0.13CrO₃ (LSCO) and Pt electrodes bridged with a porous yttria-stabilized zirconia (YSZ) have been deposited on YSZ substrates by direct-write extrusion of pastes and inks. The sensors are evaluated for their sensitivity to 200 ppm of NO_x, C₃H₈, and NH₃. There is a need to understand how variations inmore »« less

Automatic signal decoding and sensor stability of a 3-electrode mixed-potential sensor for NO_x/NH₃ quantification

Journal Article Tsui, Lok-kun; Benavidez, Angelica; Palanisamy, Ponnusamy; ... - Electrochimica Acta

Sensors to detect mixtures of NO_x/NH₃ are needed to monitor emissions of diesel automobiles where a selective catalytic reduction system uses an NH₃ mediated reaction to reduce NO_x. We report on the application of a three electrode La_0.8Sr_0.2CrO₃, Au_0.5Pd_0.5, Pt mixed potential sensor using yttria-stabilized-zirconia (YSZ) as a solid electrolyte to NO_x/NH₃ sensing. Artificial neural networks were used to automatically decode the concentrations of NO_x/NH₃ and errors of less than 15% are achieved. The optimal architecture for ANN decoding and the maximum density of training data points are also determined. The stability of the sensor was monitored by electrochemical impedancemore »« less

Final Report of a CRADA Between Pacific Northwest National Laboratory and Cummins, Incorporated (CRADA No.PNNL/283): “Enhanced High and Low Temperature Performance of NO_x Reduction Catalyst Materials”

Technical Report Gao, Feng; Szanyi, Janos; Wang, Yilin; ...

The NO_x Storage-Reduction (NSR, also known as lean-NO_x trap – LNT), is based upon the concept of storing NO_x as nitrates over storage components, typically barium species, during a lean-burn operation cycle and then reducing the stored nitrates to N₂ during fuel-rich conditions over a precious metal catalyst [1]. NO_x Selective Catalytic Reduction (SCR), on the other hand, is accomplished by deliberately introducing reductant urea into the engine exhaust to reduce NO_x with the aid of a Cu(Fe)/zeolite catalyst [2]. These two technologies have been recognized as the most promising approaches for meeting stringent NO_x emission standards for diesel vehiclesmore »« less

Passive SCR for lean gasoline NO_X control: Engine-based strategies to minimize fuel penalty associated with catalytic NH₃ generation

Journal Article Prikhodko, Vitaly; Parks, James; Pihl, Josh; ... - Catalysis Today

Lean gasoline engines offer greater fuel economy than common stoichiometric gasoline engines. However, excess oxygen prevents the use of the current three-way catalyst (TWC) to control nitrogen oxide (NO_X) emissions in lean exhaust. A passive SCR concept, introduced by General Motors Global R&D, makes use of a TWC that is already onboard to generate NH₃ under slightly rich conditions, which is stored on the downstream SCR. The stored NH₃ is then used to reduce NO_X emissions when the engine switches to lean operation. In this work, the effect of engine parameters, such as air-fuel equivalence ratio and spark timing, onmore »« less
