摘要： A lash adjuster support portion (40) is integrally formed with a lower cam carrier (50). The lower cam carrier (50) is fixed onto a cylinder head (12) into which an intake valve (20) and an exhaust valve (22) have been fitted. After a lash adjuster (60) is set in the lash adjuster support portion (40), a rocker arm (64) is placed on the intake side and a rocker arm (68) is placed on the exhaust side. Camshafts are then placed on the lower cam carrier (50) such that the rocker arm (64) contacts an intake cam (66) and the rocker arm (68) contacts an exhaust cam (70). An upper cam carrier (44) is then assembled to the lower cam carrier (50), thus completing the camshaft support structure.

摘要： It is an object of the present invention to provide a gas concentration detection apparatus that is capable of forming an accurate activity judgment when a gas concentration detection cell begins to detect gas concentration with high accuracy. When warm-up begins at time t0 in a NOx concentration detection apparatus that achieves NOx concentration detection with a NOx sensor cell after excess oxygen is discharged by an oxygen pump cell, a NOx sensor cell output (Ls) begins to rise at time t1. Subsequently, at time t2, an oxygen pump cell output (Lp) begins to rise. An inflection point appearing in the NOx sensor cell output is then located. At time t5 at which the inflection point appears, an activity judgment about the NOx sensor cell is formed.

摘要： Fuel reforming catalysts 28 generate a hydrogen-containing reformed gas when they come into contact with exhaust gas that contains a reforming fuel. Upstream and downstream air-fuel ratio sensors 58, 60 are respectively installed upstream and downstream of the fuel reforming catalysts 28. The upstream air-fuel ratio sensor 58 outputs a upstream sensor signal in accordance with oxygen concentration. The downstream air-fuel ratio sensor 60 outputs a downstream sensor signal in accordance with oxygen concentration and hydrogen concentration by using zirconia's oxygen detection capability and a change of a diffusion layer's hydrogen-concentration-dependent oxygen detection capability. An ECU 50 detects the hydrogen concentration without being affected by the oxygen concentration through the use of the upstream sensor signal in which only the oxygen concentration is reflected and the downstream sensor signal in which the oxygen concentration and hydrogen concentration are reflected. This makes it possible to establish a hydrogen concentration detection system with the common air-fuel ratio sensors 58, 60.

摘要： The present invention relates to a gas concentration detection apparatus for detecting the concentration of a specific gas component in an exhaust gas emitted from an engine, and forms a deterioration judgment about the gas concentration detection apparatus accurately and immediately. After excess oxygen is discharged by an oxygen pump cell 2, a NOx concentration detection apparatus, which uses a NOx sensor cell 4 to detect the concentration of NOx, judges whether a NOx sensor 1 is activated, that is, whether an inflection point has appeared in the NOx sensor cell output of the NOx sensor 1. If the NOx sensor 1 is not activated yet, an output increase rate Vu (t) of the NOx sensor cell output during an increase process of the NOx sensor cell output is acquired. It is then judged whether the output increase rate Vu (t) is lower than a predetermined reference value Vthl. If the obtained judgment result indicates that Vu (t)
