摘要： For use on automobiles, the invention provides a compact device for measuring the concentration of a nitrogen oxide in a combustion gas such as an exhaust gas of an internal combustion gas. The device has an ion pumping cell using an oxygen ion conductive solid electrolyte to adjust the partial pressure of oxygen in a gas diffusion chamber and a sensor such as an oxygen concentration cell using a solid electrolyte to detect the partial pressure of oxygen in the chamber. The pumping cell or the concentration cell is provided with a catalyst which decomposes the nitrogen oxide in the diffusion chamber only when the partial pressure of coexisting oxygen is sufficiently low. In the device the current supplied to the pumping cell is measured when the partial pressure of oxygen in the diffusion chamber is low enough for the activity of the catalyst and also when the oxygen partial pressure is made too high, and the concentration of the nitrogen oxide in the gas is computed from the two values of the current and the known relationship between the concentration of oxygen in the gas and the current necessary for keeping each of the high and low partial pressures of oxygen. It is convenient to use a pair of combinations of the pumping cell and the concentration cell to keep the high partial pressure of oxygen in one combination and the low partial pressure of oxygen in the other.

摘要： In an automatic test vehicle driving system on a chassis dynamometer, a table between accelerator actuator stroke and engine output torque and a table between engine friction loss power and engine speed are formed and stored by teaching operation before vehicle travel test. During travel test, command accelerator actuator strokes are determined with reference to the formed stroke-torque table when the test vehicle is accelerated or kept at a constant speed to reduce setting time for each test vehicle. Further, it is determined whether vehicle speed can be decelerated by only engine brake or by depression of brake pedal with reference to the formed friction loss power-engine speed table to prevent unnecessary braking operation. Since engine output torque can be determined in open-loop control, complicated control gain adjustment setting work can be eliminated.
