An improved spark ignition system for an internal combustion engine that includes a pair of electrodes disposed to extend from opposite sides and into a combustion chamber to form a spark gap between them that is central to the combustion chamber. Each electrode is integral with a conductive fuel delivery tube that contains a capillary passage and fuel outlet ports adjacent the electrode. The heat from combustion conducted into the electrodes and fuel delivery tubes is used to vaporize the fuel within the capillary passages before it exits the outlet ports as an atomized fog into the combustion chamber adjacent the spark gap. The vaporization of the fuel flowing in the capillary passages absorbs energy from the electrodes and thus performs a cooling effect on the electrodes. The spacing of the electrodes from opposite sides of the cylinder also allows a design that can utilize and increased spark gap to produce a larger spark across the gap.

Spark ignition and fuel injector system for an internal combustion engine

A sorption unit for air-conditioning technology apparatus with sheets for heat emission, past which water vapor is passed. The sheets are provided with zeolite bodies which are designed to have surface contact with the sheets. Channels for vapor passage are defined between bodies arranged one beside the other. Lateral grooves are formed on the top and bottom surfaces of the zeolite bodies for communicating water vapor from the surface of the zeolite bodies to the channels. A buffer section and a condenser/evaporator unit complete the sorption unit to form an air-conditioning system.
