  • Patent number: 7899605
    Abstract: During lean combustion, an ECU as a control device for a diesel engine calculates a ratio between a target A/F value and a detected A/F value detected by a A/F sensor, wherein the target A/F value is a ratio between a target air volume and a target injection amount in order to obtain a request torque. The ECU calculates the air volume after compensation during rich combustion by multiplying the target air volume with the compensation gain value. The ECU instructs an air intake throttle valve and an EGR valve to regulate those opening degrees according to the calculation result in order to decrease a torque difference between the lean combustion and the rich combustion.

  • Patent number: 7832202
    Abstract: An exhaust gas purification device senses an air-fuel ratio of exhaust gas flowing into a catalyst and performs rich purge control for supplying fuel for reduction to the catalyst. The device calculates a total reducing agent amount consumed for the reduction during the rich purge control based on the air-fuel ratio and a fresh air amount as of the rich purge control. The device sets a specified air-fuel ratio state for controlling the air-fuel ratio in a certain range enabling more precise measurement of the air-fuel ratio than in the rich purge control. The device corrects the total reducing agent amount based on a difference between an injection amount command value as of the rich purge control and the injection amount command value in the specified air-fuel ratio state and the air-fuel ratio sensed in the specified air-fuel ratio state.

  • Publication number: 20100128051
    Abstract: The present invention relates to a backlight device, a backlight control method, and a liquid crystal display device that allow light-emission brightness or chromaticity to be corrected with high accuracy and low cost. A light source controller controlling a backlight causes processing to be sequentially performed for all the blocks SA-a(1) to (16) in a correction area SA-a. The processing includes setting an area SA-a of four areas SA-a to SA-d as a correction area and causing light emission in a block SA-a(1), which is a block in the correction area SA-a, and light emission in blocks SA-b(n) to SA-d(n) which are located in the three areas SA-b to SA-d other than the correction area SA-a and whose positions in the areas correspond to the block SA-a(n) to be sequentially performed. Then, the light source controller repeats similar operations for the remaining three areas SA-b to SA-d as correction areas.
