In an air cleaner for a vehicle, a connection part of a first intake duct to a cleaner case is disposed in a front half portion of one of left and right half portions of the cleaner case, the first intake duct including a first air inlet port opening forward. A connection part of a second intake duct to the cleaner case is disposed in a rear half portion of an other of the left and right half portions, the second intake duct including a second air inlet port opening rearward. The first intake duct is formed to include a first air outlet port opening rearward inside an unpurified chamber and curve in an up-down direction in a side view, and the second intake duct is formed to include a second air outlet port opening forward inside the unpurified chamber and curve in a right-left direction in a plan view.

Air cleaner for vehicle

A device for feeding fuel from a fuel tank () to a multi-fuel engine () that uses fuel in which alcohol and gasoline are mixed in an arbitrary ratio. The internal volume of a connecting line () provided between a fuel pressure governor () and a fuel injection device () is a volume equal to or greater than the amount of fuel consumed from startup of the engine until an oxygen sensor () reaches a measurement-enabling temperature.

Fuel supply device

A fuel injection control device for a multi-fuel engine includes a corrector and a reviewer. An alcohol concentration learning unit is provided to learn an alcohol concentration in an injected fuel based on an oxygen concentration detected in an exhaust gas. A fuel injection amount controller is provided to control a fuel injection amount based on a learning value corresponding to the oxygen concentration. The corrector is configured to reduce the fuel injection amount corresponding to the learning value for a predetermined time period when the learning value is higher than a threshold value when an engine is started. The reviewer is configured to review the learning value to provide a revised learning value based on the oxygen concentration while the corrector reduces the fuel injection amount. The fuel injection amount is controlled based on the revised learning value after the corrector reduces the fuel injection amount.

Fuel injection control device and method for multi-fuel engine

A fuel injection control apparatus for a multi-fuel engine can optimize a fuel injection quantity, using only one basic injection map, irrespective of alcohol concentration of a fuel. An E-concentration determining apparatus determines alcohol concentration of a fuel, based on a measured oxygen amount in exhaust. Basic injection quantities are stored in a basic injection map. E-concentration coefficients are stored in an E-concentration coefficient table for a plurality of alcohol concentrations in the fuel. A basic injection quantity, corresponding to a current rotary engine speed and a throttle opening, is selected from the basic injection map. A concentration coefficient, corresponding to the alcohol concentration and the basic injection quantity, is selected from the E-concentration coefficient table. A fuel injection quantity calculator determines an applied fuel injection quantity by multiplying the basic injection quantity by the concentration coefficient. Further adjustments using a number of additional correction coefficients may be made, as needed.

In this incubator, the door rotation restricting means in the operating state restrains the rotation of the door in the opening direction beyond the operating angle. Thus, in the case that the door rotation restricting means is in the operating state, even if the door is pushed by the accommodated baby from the inside of the hood under the state wherein the door is not fixed by the door fixing means in a closing state, the door does not rotate in the opening direction beyond the operating angle and the angle of the door does not exceed the operating angle. Therefore, even if opening and closing operation of the nursing window is not securely performed, at least the environment inside the hood hardly deviates from the physiological environment appropriate for the accommodated baby.

Incubator

In this incubator, when the angle of a door to a nursing window of a hood is smaller than a rotation restricting angle, door rotation restricting means restrains the rotation of the door in an opening direction. Because of this reason, when the angle of the door is smaller than the rotation restricting angle, the door is not rotated in the opening direction beyond the rotation restricting angle and the angle of the door does not exceed the rotation restricting angle, even if the door is pushed by an accommodated baby from the inside of the hood under the state wherein the door is not fixed in the closing state by a door fixing device. Therefore, even if opening and closing operation for the nursing window is not securely performed, the environment inside the hood hardly deviates from the physiological environment appropriate for the accommodated baby to say the least.
