摘要： An engine control method and an engine control system that can inhibit the emission of NOx and reduce noise are provided. An engine control method in which an engine 2 is caused to perform diffusion combustion at normal times and switched from diffusion combustion to premixed combustion when an engine load is low, wherein when the engine 2 is switched from the diffusion combustion to the premixed combustion, an oxygen concentration in an intake air of the engine 2 is found and when the found oxygen concentration exceeds a threshold of NOx generation oxygen concentration that has been set in advance, switching from the diffusion combustion to a fuel injection mode of the premixed combustion is stopped, and when the found oxygen concentration then becomes equal to or less than the threshold of NOx generation oxygen concentration, switching is performed to the premixed combustion.

摘要： A diesel engine having a reentrant cavity (11) provided in the top section of a piston (4), a fuel injection means (9) for injecting fuel toward the cavity (11), an exhaust gas recirculation means (19) for recirculating a part of exhaust gas into a combustion chamber, and a control device (26) for controlling fuel injection timing set by the fuel injection means (9) and also controlling an EGR rate or EGR amount set by the exhaust gas recirculation means (19). In a predetermined operation region, the control device (26) controls the timing of fuel injection set by the fuel injection means (9) so that the injection of the fuel is completed before the compression upper dead end of the piston (4) and that the entire injected fuel enters into the cavity (11), and also controls an EGR rate or EGR amount set by the exhaust gas recirculation means (19) so that the fuel injected by the fuel injection means (9) is ignited near the compression upper dead end of the piston (4) after the completion of the fuel injection. The control device (26) thus realizes premix combustion. Favorable premix combustion is realized, and, even if the combustion is switched to diffuse combustion, favorable combustion can be achieved.

摘要： Provided are a gear device in which lubricating oil for cooling and lubricating gears to be driven therein is adjusted to a temperature and an amount suitable for the speed of a vehicle, and a vehicle having the gear device mounted thereon. In a transmission 1 which adjusts the temperature of lubricating oil OL by supplying the lubricating oil OL from a lower part of a housing (enclosure) 11 of the transmission 1 into a heat exchanger 12 by means of a circulation pump 13 and causing the lubricating oil OL and engine cooling water W to exchange heat with each other in the heat exchanger 12, the level of the lubricating oil OL retained in an oil pan 11a when the circulation pump 13 is stopped is defined as a highest oil level L1, while the level of the lubricating oil OL retained in the oil pan 11a when the amount of the lubricating oil OL pumped up by the circulation pump 13 is maximum is defined as a lowest oil level L2. The heat exchanger 12 is disposed at a position outside the housing 12 and higher than the highest oil level L1. The transmission 1 comprises a control device 20 which controls the amount of the oil to be pumped up by the lubricating pump 13 to adjust the height of the level OL of the oil which varies between the highest oil level L1 and the lowest oil level L2.

摘要： A diesel engine controller in which a normal injection mode for realizing normal combustion and a premix injection mode for realizing premix combustion are set, the normal injection mode is carried out when the actual operating state of the engine is in a normal region and the premix injection mode is carried out when the actual operating state of the engine is in a premix region. One control mode is switched forcibly to the other control mode when the engine enters a predetermined transient state while one operation mode is carried out in one corresponding engine operation region. Switching can be made earlier than usual and desired acceleration performance can be attained especially at the time of acceleration.
