According to an internal combustion engine fuel injection control apparatus and control method, when an operating region of the engine shifts from a fuel cut region in which no fuel is injected to a low load region in which a small amount of fuel is injected, or visa versa, at least one pilot injection is executed ahead of a main injection in the low load region, and the number of pilot injections is determined according to the engine coolant temperature. This injection control makes it possible to ensure drivability while suppressing the amount of HC produced.

A metallic sliding material including at least a support member with a sliding surface and an inorganic compound coating layer formed on the sliding surface is disclosed. The sliding surface is formed from an aluminum alloy or a reinforcing material-containing aluminum alloy. The inorganic compound coating layer is formed from at least one aluminum compound, and at least one phosphorus compound, and at least one member selected from the group of molybdenum compounds, tungsten compounds, and chromium compounds. These compounds are present in such concentrations that molybdenum, tungsten, and chromium collectively constitute 2 to 48% by weight of the inorganic compound coating layer, aluminum constitutes 1 to 25% by weight of the inorganic compound coating layer, phosphorus constitutes 1 to 25% by weight of the inorganic compound coating layer, and the balance of the inorganic compound coating layer is oxygen and impurities.
摘要:
A compressor equipped with a compressing unit comprising a compressing section and a motor section which are connected to each other and Which are encased in a closed vessel, the compressing section including a crank shaft rotatable so that a piston reciprocates within a cylinder and the motor section comprising a rotor and stator and disposed at a lower side of the compressing section, the rotor being connected to the crank shaft so that the crank shaft is rotatable in response to driving of the motor section. Springs are provided between the compressing unit and the closed vessel so as to elastically support the compressing section and the motor section, and first and second balance weights are respectively provided on upper and lower portions of a rotor of the motor section. The first and second balance weights are determined on the basis of the resultant load to be applied to an eccentric portion of the crank shaft, a con'rod and the piston, the loads of the first and second balance weights and distances among the first and second balance weights and the eccentric portion of the crank shaft.

A fuel cell vehicle air-conditioning apparatus includes: a cooling system that adjusts a temperature of a fuel cell; a waste heat collection unit that collects at least a part of waste heat from the fuel cell and uses the collected waste heat to heat a cabin interior of the fuel cell vehicle; and a heat creation unit that creates heat for heating the fuel cell vehicle. The fuel cell vehicle air-conditioning apparatus calculates a fuel consumption amount required for the fuel cell to generate a total power generation amount, which is a sum of a heating power generation amount and a travel power generation amount, calculates an optimum temperature, which is a temperature of the fuel cell at which the fuel consumption amount reaches a minimum, and controls the cooling system such that the temperature of the fuel cell reaches the optimum temperature.
