摘要： In order to accurately control the operation of the engine while still achieving near optimal swirl rate control, the swirl is controlled by a valve which is separate from the engine throttle valve and which is basically controlled in response to the pressure prevailing across the same. Various operating parameters such as the instant air-fuel ratio of the charge being combusted in the combustion chambers are utilized to modify prerecorded values to those which will induce the best setting for the valve.

摘要： A filter is disposed in the exhaust passage of an internal combustion engine in order to trap particles suspended in exhaust gas. A burner serves to burn off the particles deposited on the filter. Either the pressure in the exhaust passage at a point upstream of the filter or the pressure difference in the exhaust passage across the filter is selectively sensed. In place of sensing the pressure difference, the pressure in the exhaust passage at a point downstream of the filter may be sensed. The ratio between the upstream pressure and the pressure difference, or the ratio between the upstream pressure and downstream pressure is determined an as indication of the degree of clogging of the filter. The burner is operated on the basis of this ratio.

摘要： A projection television apparatus which has three monochromatic cathode-ray tubes, two type of dichroic mirrors, and a lens. Red, green and blue images from the three tubes are combined into the color image by the two types of dichroic mirrors and the resulting image is enlarged and projected on the screen by one lens. The two types of dichroic mirrors are crossed at a right angle in the shape of an "X". Each type of dichroic mirror is split in two through the line of intersection and the two parts of the respective dichroic mirrors of each type have different transmission characteristics, so that color shading is improved.

摘要： An engine system comprises an internal combustion engine and an exhaust gas treatment system, such as a three-way catalytic converter or an oxidation catalytic converter. The engine has an additional intake means, in addition to a main intake means for admitting by induction an air fuel mixture to a combustion chamber, for admitting under pressure above atmospheric pressure air to the combustion chambers during a period initiating during the exhaust stroke and terminating during the intake stroke for the purpose of expelling residual gas from the combustion chamber to bring about a stable combustion.

摘要： Disclosed herein is an engine system which comprises an internal combustion engine, an air admission system to admit scavenging air, under pressure, into an engine cylinder through an additional intake valve and an EGR system. The air admission system includes an air pump and an EGR conduit of the EGR system having an inlet end connected to the engine exhaust conduit and an outlet end connected to the air admission system upstream of the air pump to effect admission of recirculated exhaust gas through the additional intake valve together with scavenging air. With this EGR system and the replacement of residual gas with scavenging air, the rate of exhaust gas in the engine cylinder upon ignition is kept substantially constant over varying partial loads.
