  • Patent number: 8534082
    Abstract: An engine starter system that predicts when starter failure is imminent. The engine starter system monitors engine starter crank speed, battery voltage and ambient air temperature. The crank speed, battery voltage and ambient air temperature are communicated to a controller which compares the crank speed for the measured battery voltage and air temperature to a predicted crank speed for the measured battery voltage and air temperature. If the crank speed is lower than the predicted crank speed, a signal is sent to an alarm.

  • Patent number: 8534569
    Abstract: In a cooling device for a vehicle having a main passage through which coolant water is circulated between the interior of an engine and a radiator 13, a heater passage through which the coolant water is circulated between the interior of the engine and a heater core 15, and a thermostat 18 that operates in response to the temperature of the coolant water and selectively permits and stops circulation of the coolant water in the main passage, the heater passage is used as a heater/bypass passage, which functions also as a bypass passage, through which the coolant medium is circulated without passing through the radiator 13 when the engine warms up. This makes it unnecessary to form a separate bypass passage, thus simplifying the passage configuration.

  • Patent number: 8505319
    Abstract: The invention relates to an absorption air conditioner that comprises a desorber (100), a condenser, an evaporator and an absorber, wherein the absorbing fluid may consist of lithium bromide. The method comprises the following steps: calculating the concentration of the absorbing fluid solution at the outlet of the desorber (100); and comparing the calculated concentration with a predetermined critical value and, if the calculated concentration gets closer to the predetermined critical value, increasing the charge loss in the duct (20) connecting the desorber (100) to the condenser, which interrupts the condensation in the condenser and results in a pressure increase in the desorber that stops the desorption and in a concentration increase, the charge loss being on the other hand reduced for resuming the desorption when the calculated concentration deviates from the predetermined critical value. The invention can be used in automobiles and absorption air-conditioners.
