Abstract: The technique of the present invention produces a first fuel-air mixture containing a first fuel and the air at a specific ratio, which does not allow for auto ignition of the first fuel-air mixture by simple compression, in a combustion chamber. The technique then injects a second fuel, which has a higher octane value than that of the first fuel, into a partial area of the combustion chamber, so as to produce a second fuel-air mixture. The technique ignites the second fuel-air mixture for combustion, so as to compress and auto-ignite the first fuel-air mixture. The second fuel has the higher octane value, so that a combustion start timing of the second fuel-air mixture is reliably regulated by ignition. Namely the technique positively controls the timing of auto ignition of the first fuel-air mixture. Setting an adequate value to the ignition timing thus effectively prevents the occurrence of knocking in an internal combustion engine that adopts a premix compression ignition combustion system.

Abstract: A motor-assisted turbocharger is composed of a turbine driven by energy of exhaust gas, a compressor rotated by the turbine and a rotary electric machine for assisting rotation of the compressor. The turbine, the compressor blade and the rotary electric machine are connected to each other by a common rotating shaft.

Abstract: An energy-efficient heat pump water heating system determines whether to energize a heat pump by interpreting readings from one or temperature sensors based on two thresholds. The heat pump is energized if the detected temperature falls below a first threshold and de-energized when the detected temperature rises above a second threshold. The thresholds may correspond to outputs of two or more sensors. Using multiple temperature thresholds improves the temperature sensing capabilities of the system, thereby improving energy efficiency by matching heat pump operation with hot water demand more closely than previously known systems.

Abstract: A control and method are disclosed to determine the relative duct sizes of a plurality of ducts leading to a plurality of zones in a multi-zone HVAC system. In a disclosed method, the dampers leading to each of the zones are operated such that one damper is held more open than the remaining dampers, and a system component is monitored as air is blown through the duct. In particular, a blower speed may be monitored. Once the blower speed is monitored, for one damper being open, with the remaining dampers being relatively closed, another damper is opened and the first is closed. This process continues until relative information is gathered for each of the zones. This relative information is then utilized to determine the relative sizes of the ducts leading to each of the zones as a percentage of the total duct size. The relative duct size information is then utilized to perform various control methods.
