  • Patent number: 10532316
    Abstract: A microcomputer acquires first and second NH3 electromotive forces from a first NH3 detection section and a second NH3 detection section, and computes a NH3 concentration, which is the concentration of NH3 contained in exhaust gas. The first and second NH3 detection sections output the first and second NH3 electromotive forces which vary with both the concentrations of NH3 and a flammable gas contained in the exhaust gas. The microcomputer acquires a second pumping current from an NOx detection section and computes an NOx concentration, which is the concentration of NOx contained in the exhaust gas. The NOx detection section outputs the second pumping current which varies with the concentration of NOx and the concentration of NH3. The microcomputer determines whether or not the exhaust gas contains the flammable gas based on at least the first and second NH3 electromotive forces and the second pumping current.

  • Patent number: 10512918
    Abstract: The subject of the invention is a procedure, a filter module, and an air cleaning device composed of such filter modules for the highly efficient cleaning of air containing small contaminating particles. In the course of the procedure, the principle of adhesion and repelling effect is exploited to capture the contaminating particles in the device composed of an appropriate number of filter modules (1). The air to be cleaned is moved like a quasi-electrodynamic linear engine in the device, so that the mass and/or size of the coagulated particles is increased by the powers of two as necessary while passing through two sequential filter modules (1), up to 220 value. This way, the flow velocity of the fine grains with increased mass is decreasing gradually and they are separated or fall out from the flow space, meaning that particles with a starting size below 1 micrometre, in the nano-range, which are the most harmful to the human body, may also be captured.

  • Patent number: 10393713
    Abstract: A method for operating a probe having a pumped reference cell. A pulse-width-modulated pump current is applied to the reference cell at a first point in time. In accordance with the first point in time, a first voltage characteristic value (representing the voltage applied to the reference cell) is determined within a first time frame. The pulse-width-modulated pump current applied to the reference cell is switched off at a second point in time. A third point in time is determined, at which a pulse-width-modulated pump current applied to the reference cell is switched off. In accordance with the third point in time, a second voltage characteristic value (representing the voltage applied to the reference cell) is determined within a second time frame. The first and second voltage characteristic values are used to determine a diagnostic characteristic value, which is representative of an error in determining the nitrogen oxide concentration.

  • Patent number: 9856810
    Abstract: A fuel cut during deceleration is executed at time point t1. An oxygen storage amount (rOS) which increases with this fuel cut is estimated based on an exhaust air-fuel ratio and an intake air quantity. When the oxygen storage amount (rOS) reaches a threshold value (at time point t2), a target compression ratio (tCR) is corrected to become lower than a basic target compression ratio (tCR). Although a fuel recovery is executed at time point t4, a combustion temperature is lowered because of the lowering of the mechanical compression ratio, so that a production of NOx in a combustion chamber is suppressed. Therefore, worsening of NOx is suppressed even if the oxygen storage amount (rOS) of exhaust-emission purification catalyst (4) is excessive.

  • Patent number: 9470650
    Abstract: Sensors for sensing/measuring one or more analytes in a chemical environment. Each sensor is based on a semiconductor structure having an interfacial region containing a two-dimensional electron gas (2DEG). A catalyst reactive to the analyte(s) is in contact with the semiconductor structure. Particles stripped from the analyte(s) by the catalyst passivate the surface of the semiconductor structure at the interface between the catalyst and the structure, thereby causing the charge density in the 2DEG proximate the catalyst to change. When this basic structure is incorporated into an electronic device, such as a high-electron-mobility transistor (HEMT) or a Schottky diode, the change in charge density manifests into a change in an electrical response of the device. For example, in an HEMT, the change in charge density manifests as a change in current through the transistor, and, in a Schottky diode, the change in charge density manifests as a change in capacitance.

  • Patent number: 9188073
    Abstract: The invention relates to a method and device for diagnosing deviations in a single cylinder lambda control in an internal combustion engine having at least two cylinders and an exhaust gas sensor designed as a broadband lambda sensor, wherein a pump current is evaluated by means of a pump cell and the pump current is used at least temporarily for an individual cylinder lambda control. According to the invention, a pump voltage or a pump voltage change is determined via the pump cell in addition to the pump current and the value is transmitted to a diagnosis apparatus. Deviations in the single cylinder lambda control can thus be better diagnosed without additional material expense according to the invention, which provides advantages in particular in respect of tightened rulemaking in on-board diagnosis. A preferred application of the method is the use in internal combustion engines having multi-bank exhaust systems.
