摘要： An oxygen concentration detector includes an air-fuel ratio sensor, a heater that heats the air-fuel ratio sensor, a heater controller that supplies electric power to the heater such that the air-fuel ratio sensor reaches an activation temperature, and an element temperature detector that detects a temperature of an element of the air-fuel ratio sensor. The heater controller detects a rate of decrease in the temperature of the element of the air-fuel ratio sensor based on the temperature detected by the element temperature detector, and determines that the sensor element is wetted when the detected rate of decrease is greater than a reference value. The element temperature detector can detect the sensor element temperature based on an impedance of the element. The heater controller can prevent the supply of electric power to the heater if it is determined that the sensor element is wetted. The air-fuel ratio sensor can be provided in an exhaust passage of an engine.

摘要： In an initial predetermined period of time for supplying electric power to the electrically heated catalyst mounted on the vehicle, a maximum of electric power is supplied from the power source to simplify the complex heat control operation. Simultaneously with starting of the engine, the electrically heated catalyst is connected to the power source to start supplying the electric power, and a maximum electric power permitted by the power source is supplied for a first predetermined period of time after which the electrically heated catalyst is just about to be activated. After the first predetermined period of time has passed, the electric resistance of the electrically heated catalyst is measured until a second predetermined period of time elapses. Depending upon the thus measured electric resistance, the amount of electric power supplied from the power source to the electrically heated catalyst is controlled by feedback so that the electric resistance of the electrically heated catalyst is maintained at a predetermined target electric resistance. The power source for the electrically heated catalyst may be the alternator driven by the drive source of the vehicle. Furthermore, the power source may be the alternator from starting the engine until the first predetermined period of time elapses, and may, then, be the battery from the elapse of the first predetermined period of time until the second predetermined period of time elapses. Being controlled as described above, the electric power is supplied to the electrically heated catalyst, immediately after starting the engine, easily and reliably.

摘要： A prism has at least two optical planes and one of the planes is a boundary plane with mixed fuel. On one of two planes, a light emitting element is mounted and illuminates light to the boundary plane through the prism. A light receiving element receives light reflected from the boundary plane and converts the reflected light into electrical signals. Then a detector modifies the electrical signals from the light emitting element according to the detecting result and outputs them as detecting signals representative of the fuel mixture ratio. The temperature of the mixed fuel may be detected by a temperature sensor in which case the electrical signals are also modified to compensate for temperature changes of the mixed fuel.

摘要： A combustion process sensor for detecting combustion processes occurring in a combustion chamber of an engine has a generally tubular mounting casing to be screwed into a threaded hole in the combustion chamber wall and a quartz-glass rod axially extending in the mounting casing and held in position therein. The casing includes two axially aligned generally tubular members rigidly secured together at their own ends. The quartz-glass rod has a first portion remote from a sensing end thereof adapted to be exposed to combustion flame in the combustion chamber, and a second portion between the first portion and the sensing end. The first portion is secured to one of the two tubular members of the casing, while the second portion is supported from the casing only by a vibration damping material disposed in engagement with the outer peripheral surface of the quartz-glass rod and the inner peripheral surface of the casing.

摘要： A plurality of cylinders are provided. An in-cylinder pressure sensor is mounted on each of the plurality of cylinders. A combustion parameter (e.g., the amount of generated heat) is calculated from the output of the in-cylinder pressure sensor. The air-fuel ratio for a cylinder is enleaned by reducing a fuel injection amount until the combustion parameter coincides with a predetermined value. Each cylinder is subjected to fuel injection amount reduction control so that the combustion parameter coincides with the predetermined value. The air-fuel ratio for each cylinder is then calculated in accordance with the reduction amount of fuel injection amount. The calculated air-fuel ratios are compared to detect an air-fuel ratio imbalance between the cylinders.
