摘要:
According to methods known in prior art, a parameter which depends on the acceleration of the internal combustion engine is determined by means of a monitoring and analyzing system and is compared with a threshold value. According to the inventive method, the spread of said acceleration-dependent parameter is used for adjusting the threshold value to changes in the smoothness of running of the internal combustion engine.

We have discovered a method of providing a thin approximately from about 2 Å to about 100 Å thick TaN seed layer, which can be used to induce the formation of alpha tantalum when tantalum is deposited over the TaN seed layer. Further, the TaN seed layer exhibits low resistivity, in the range of 30 μΩ cm and can be used as a low resistivity barrier layer in the absence of an alpha tantalum layer. In one embodiment of the method, a TaN film is altered on its surface form the TaN seed layer. In another embodiment of the method, a Ta film is altered on its surface to form the TaN seed layer.

The present invention is directed to substituted coumarins and quinolines and analogs thereof, represented by the general Formula I: wherein A, B, X, Y, and Z are defined herein. The present invention also relates to the discovery that compounds having Formula I are activators of caspases and inducers of apoptosis. Therefore, the activators of caspases and inducers of apoptosis of this invention can be used to induce cell death in a variety of clinical conditions in which uncontrolled growth and spread of abnormal cells occurs.
摘要:
To balance ozone sensors for the onboard diagnosis of a catalytic element which is arranged in a vehicle and is exposed to an ambient airstream, for breaking down ozone, predetermined enable conditions allowing the sensor balancing to be carried out are checked, and if the enable conditions are fulfilled the values of the output signals from the ozone sensors are recorded and compared with one another. This comparison gives a deviation value which is characteristic of the deviation between the two values, and the deviation value is used to decide whether sensor balancing is required and indeed possible. If sensor balancing is required and possible, the values of the output signals from the ozone sensors are compared with a threshold value and depending on the result of this comparison either an additive or a multiplicative correction of the values of the output signals is performed.
摘要:
A method for checking an exhaust gas cleaning plant connected to an internal combustion engine in an exhaust gas tract that includes a catalytic converter having oxygen storage characteristics as well as a NOx sensor positioned downstream in the exhaust gas tract that emits a sensor signal depending on the NOx and the NH3 concentration in the exhaust gas in which case the internal-combustion engine is operated with a periodic air/fuel ratio oscillating around the value lambda=1 and that the average of the sensor signal is formed over one period or several periods and if the threshold value of the average is exceeded, damage to the monolith of the catalytic converter is detected.
摘要:
During the starting of an internal combustion engine with fuel injection, so-called preliminary injections (I) are dispensed according to a certain preliminary injection strategy in order to build up a wall film in the cylinders and simultaneously provide an ignitable mixture for the initial combustion. To avoid a situation where the preliminary charges during the starting phase are too rich or too lean, different quantities of fuel are chosen for the preliminary injections (I), depending on the charges to be expected in the relevant cylinders.
摘要:
For a three-way catalytic converter system with a preliminary catalytic converter, a main catalytic converter and an oxygen sensor with a constant characteristic curve disposed between the two catalytic converters, a method for resetting the oxygen concentration in the preliminary catalytic converter and the main catalytic converter in the event of a transition from lean-burn operation to stoichiometric operation includes exposing both catalytic converters to a rich mix until the desired oxygen concentrations have been reached. In the process, the constant measurement signal from the oxygen sensor and the measurement signal from an air mass flow meter are used to calculate the quantity of oxygen that is released to the exhaust gas from the main catalytic converter, in order to end rich-burn operation when a predetermined desired value is reached.
