  • Patent number: 7990100
    Abstract: A hybrid forklift truck is provided with an engine, a battery-driven motor generator, and a battery control device that prevents excessive exhaustion or charging of the battery. The state of charge (SOC) of the battery is determined from the battery voltage and SOC when battery current is zero for at least a predetermined time period and from the battery voltage, current and SOC when discharge current is constant for at least a predetermined time period. SOC is revised whenever battery current is zero or constant for at least the predetermined time period, and SOC at any point of time in operation of the forklift truck is estimated by integrating battery current from the SOC revision and subtracting the integrated current from the revised SOC. Drive power of the engine and motor generator are allocated according to a relationship between permissible discharge and charge current and SOC of the battery.

  • Patent number: 7704174
    Abstract: A vertical internal combustion engine includes a crankshaft enclosed in a crank chamber, a belt-drive transmission mechanism held in a belt chamber and including a rubber belt for transmitting power of the crankshaft to a camshaft included in a valve train, and a transmission case defining the belt chamber. The transmission case has a lower case between the crank chamber and the belt chamber. The belt has a part extending over the crank chamber, and the lower case is disposed to screen the part of the belt from the crank chamber. The belt is lubricated by oil in oil-containing gas from the crank chamber. Thus the oil containing gas is prevented from excessively contacting the rubber belt, so that the life of the belt is extended.
