Abstract: Systems and methods of optimizing cranking times of a diesel engine are provided. Factors such as cold weather, diesel fuel quality, and others may negatively impact cranking times of a diesel engine. Glow plugs used to heat combustion chambers of the diesel engine are controlled using pre-glow durations during which the glow plugs are pre-heated prior to cranking the diesel engine. Based on learned operating vehicle conditions or external conditions, the pre-glow durations can be adjusted to counteract the factors that have a negative impact on the cranking time of the diesel engine, and ultimately reduce cranking time of the diesel engine.

Abstract: When the temperature of the exhaust gas flowing into an NSR catalyst exceeds a specific threshold temperature that is determined on the basis of the cetane number of fuel in such a way that the specific threshold temperature is set lower when the cetane number of the fuel is low than when it is high, fuel is supplied to the exhaust gas by fuel supply device to perform an NOX reduction process for the NSR catalyst. If the quantity of heat generated in the NSR catalyst per unit time is smaller than a specific value while the NOX reduction process is being performed, the NOX reduction process in progress is suspended, and the NOX reduction process is performed later on when the temperature of the exhaust gas flowing into the NSR catalyst exceeds an updated threshold temperature higher than the specific threshold temperature.

Abstract: An object is to enable an exhaust gas purification system to bring about satisfactory oxidation of fuel in an oxidation catalyst in a temperature raising process of a filter, thereby allowing fuel supply to be performed at as low a temperature as possible. In the exhaust gas purification system, when the temperature of the exhaust gas flowing into the oxidation catalyst exceeds a specific threshold temperature that is determined based on the cetane number of fuel, a controller performs the temperature raising process. If the quantity of heat generated in the oxidation catalyst per unit time is smaller than a specific value while the temperature raising process is being performed, the temperature raising process in progress is suspended. The temperature raising process is resumed later on when the temperature of the exhaust gas flowing into the oxidation catalyst exceeds an updated threshold temperature higher than the specific threshold temperature.

Abstract: An electric motor control device is capable of reducing vibration in a speed fluctuation range at a high frequency. The electric motor control device includes a target rotation speed setting unit that sets the target rotation speed of an electric motor, a rotation speed estimation unit that calculates an estimated rotation speed of the electric motor, and a drive command signal generation unit that generates a drive command signal for the electric motor so as to eliminate a rotation speed difference between the target rotation speed and the estimated rotation speed. The rotation speed estimation unit includes an error calculation unit that calculates an error related to rotation of the electric motor and an estimated corrected rotation speed calculation unit that calculates an estimated corrected rotation speed by taking the error as input and correcting the estimated rotation speed.

Abstract: An automatic transmission configured with four planetary gear mechanisms, three clutches, and three brakes configured so as to selectively provide ten forward speeds and a reverse speed. The configuration enables smoother acceleration due to the number of different shift speeds available, and provides a generally more comfortable driving experience. The combination also enables a reduction of loss of efficiency that that occurs due to the meshing between gears and enhances the torque transfer efficiency.

Abstract: An automatic transmission is configured to achieve at least ten forward speeds and one reverse speeds. This is achieved through the use of two planetary gear sets with a plurality of clutches and brakes configured to operably couple different components of the two planetary gears to achieve different speeds. For example, operation of a first clutch inputs decelerated rotation of a reduction planetary gear to a third sun gear. Operation of a second clutch transmits from an input shaft to a third ring gear, a third clutch inputs decelerated rotation of the reduction planetary gear to the second sun gear, a fourth clutch transmits from the input shaft to the second carrier, a first brake prevents a second sun gear from rotating, a second brake prevents a carrier from rotating, a third brake capable prevents a third ring gear from rotating.

Abstract: An inner rotary hook has a needle drop hole, and side wall portions formed over the drop hole and defining a space for passage therethrough of a sewing needle. The side wall portions are located adjacent to opposite sides of the needle passing through the space and extend from a region in front of the needle to a region behind the needle. The side wall portions can abut against an upper thread, passed through a hole of the needle, near a bottom dead point of the needle. If any of two portions of the thread located forward and rearward of the needle has strayed laterally, it can abut against one of the wall portions. Consequently, it is possible to prevent the front-side upper thread portion from circling around behind the needle, but also prevent the rear-side upper thread portion from straying laterally to form a laterally-protruding loop.

Abstract: An air-cleaner includes a housing attached to an induction system of an internal combustion engine. The air-cleaner includes a filter element located within the housing and separating the internal of the housing into a dust side and clean side, the dust side having an introduction portion for introducing an external air into the housing, the clean side having a feeder portion for feeding a filtered air to an engine. The air-cleaner includes a plate-shaped adsorption element including an adsorbent to adsorb a vaporized fuel returned from an engine side and permitting an air to pass therethrough, the adsorption element arranged to cross the direction of an air flow and fitted to occupy the entire surface of the clean side in the housing. The adsorption element defines a port connecting the filter element and the feeder portion, and includes a valve disc to open or close the port. The valve disc is controlled to open during air inspiration for permitting an air to flow toward the feeder portion.
