    摘要: An optical rangefinder based on time-of-flight measurement, radiates pulsed light toward an object (70), and receives reflected light from the object, the receiver operating in a photon counting mode, so as to generate a pulse for a detected photon. There is a variable probability of a photon detection on the receiver, and a controller (370, 380, 390; 365, 470, 475, 380, 390; 570, 580, 590, 390) controls the photon detection probability of the receiver, based on a light level. By controlling the detection probability according to a light level, the receiver can have an increased dynamic range, and without the expense of using optical components. This can apply even while detecting very weak signals since the receiver can still be in a photon counting mode while the detection probability is controlled. The light level can be indicated by an output of the receiver itself, or by another detector external to the receiver.

    摘要: A submillimeter wavelength radar system has a receiver (20, 27, 90) for receiving and downconverting signals from content in a field of view of the system and a signal processor (30) arranged to determine information about the content from the downconverted signals, the radar system being arranged to obtain signals of the same points in the field of view from different illumination or receiving angles by having multiple illumination or receive positions, and the signal processor being arranged to use the determined information from the signals from the two or more angles to determine location or orientation of the content. By using information from different angles, it becomes possible to address or overcome the drawback of submillimeter wavelengths that most of the reflection is specular and so only surfaces of an object facing the radar system are detectable, meaning that many objects are unrecognisable.

    摘要: A particulate trap for use with a diesel engine is high in particulate trapping capacity and regenerating capacity and low in pressure drop, and yet is compact and inexpensive. This trap has a filter element made up of a plurality of tapered filter members formed from a fabric of heat-resistant metal fibers. The filter members have different diameters from each other and are nested concentrically one inside the other so that the adjacent filter members are positioned inversely. Each filter member is connected at its large-diameter end to the small-diameter end of the immediately outer filter member to alternately close the exhaust inlet and outlet ends of the gaps between the adjacent filter members. The filter element thus formed is mounted in a metal case provided in an exhaust line and used as a particulate trap. With this arrangement, it is possible to increase the particulate trapping area of the filter and the exhaust inlet openings without increasing the size of the entire trap. Such a trap is less likely to suffer pressure drop and is highly durable.

    摘要: A sequential turbocharger system for an internal combustion engine with an exhaust gas recirculation system. The sequential system includes a large-volume turbocharger and a small-volume turbocharger, which are arranged in series in the direction of the flow of gases. A bypass passageway is connected to an exhaust pipe to thereby bypass the turbine of the small-volume turbocharger, and an exhaust switching valve is arranged in the bypass passageway for controlling the flow of exhaust gas to the turbine of the small-volume turbocharger. The EGR system includes an exhaust gas recirculation passageway for introducing an amount of exhaust gas into the intake pipe of the engine. The exhaust gas for recirculation is taken out from the intake pipe at a position located between the turbines of the small-volume and large-volume turbochargers.

    摘要: An internal combustion engine comprising an auxiliary chamber connected to a main chamber via a connecting passage. A raised portion is formed on the inner wall of the auxiliary chamber. The auxiliary chamber is divided into a first chamber and a second chamber. The connecting passage is tangentially connected to the inner wall of the second chamber at a position opposite to the raised portion with respect to the axis of the auxiliary chamber. A fuel injector having a pair of injection nozzles is arranged in the first chamber. One of the injection nozzles is directed to the tip of the raised portion. The other nozzle is directed to the inner wall of the auxiliary chamber, which is located at a position opposite to the raised portion with respect to the axis of the auxiliary chamber. The fuel is always injected from the nozzle towards the tip of the raised portion independently of the operating condition of the engine, while the injecting operation of the other nozzle is started when the load of the engine is increased beyond a predetermined level.

    摘要: Disclosed is an internal combustion engine having no intake throttle valve and comprising a main chamber and an auxiliary chamber which are interconnected with each other via a connecting passage. An annular raised portion is formed on the inner wall of the auxiliary chamber, and the auxiliary chamber is divided into a first auxiliary chamber and a second auxiliary chamber by the annular raised portion. The connecting passage is tangentially connected to the inner wall of the second auxiliary chamber. The nozzle of a fuel injector is disposed in the auxiliary chamber and is directed to the recess which is formed in the second auxiliary chamber beneath the annular raised portion at a position located opposite to the inner wall to which the connecting passage is tangentially connected with respect to the axis of the auxiliary chamber. The spark gap of a spark plug is located in the recess of the second auxiliary chamber. The sum of the volumes of the auxiliary chamber and the connecting passage is more than 80 percent of the sum of the volumes of the auxiliary chamber, the connecting passage and the main chamber when said piston reaches the top dead center position. The exhaust gas is recirculated into the intake system of the engine so that the exhaust gas recirculating rate becomes 30 through 40 percent. The amount of the fuel injected from the injector is so regulated that the total air-fuel ratio is increased to within 30 through 100:1 in accordance with a decrease in the level of the load of the engine. The ignition timing is advanced to within the range of 15 through 50 degrees before the top dead center position of the compression stroke in accordance with a decrease in the level of the load of the engine.

    摘要: Disclosed is an internal combustion engine comprising a main chamber and an auxiliary chamber which are interconnected with each other via a connecting passage. An annular raised portion is formed in the inner wall of the auxiliary chamber so as to divide the auxiliary chamber into a first auxiliary chamber and a second auxiliary chamber. The connecting passage is tangentially connected to the second auxiliary chamber for creating a strong swirl motion in the first auxiliary chamber. This strong swirl motion causes a secondary swirl motion in a portion of the recess, which is located at a position opposite to the inner wall to which the connecting passage is tangentially connected with respect to the axis of the auxiliary chamber. The nozzle of a fuel injector is disposed in the auxiliary chamber so as to be directed to the recess portion for forming a rich air-fuel mixture therein. The spark gap of a spark plug is located in the recess portion. An additional connecting passage communicating the recess portion with the main chamber is formed in the cylinder head and is tangentially connected to the inner wall of the recess portion for strengthening the secondary swirl motion.
