An electric drive unit includes an electronic control and monitoring module integrally connected to an electric motor. The housing of the electric motor has a double-walled construction to form a water jacket with cooling water passages therein. The electronic module includes at least one high power component that requires cooling. This component is mounted directly on a cooling insert that extends through a recess in the electronic module housing and is inserted in an opening provided in the outer wall of the motor housing. In this manner, the cooling insert is integrated into the water jacket of the motor housing and is directly cooled by the cooling water flowing in the cooling passages. A very compact and reliable construction is achieved, in which the electric motor and the electronic module share a common water cooling circuit. External water hoses and external electrical connections between the electric motor and the electronic module are avoided.

The present invention is directed to a water making device that collects the moisture contained in the atmosphere and condenses it into high purity water. In one embodiment, moist air entering the water making / water cooling system flows across an air filter, then a precooler heat exchanger (where the air stream is cooled to or close to its dew point) and then a water extraction heat exchanger, where the air stream is cooled further and water is extracted. The water that leaves water extraction heat exchanger is collected in a water collection device and passes from there through a primary water filter into a water storage tank. The air stream then passes across a reheat heat exchanger and exhausted to the outside. A water circulation pump extracts water from the water storage tank and circulates the water stream through an evaporator of a vapor compression refrigeration system, where the water stream is chilled, then through the water extraction heat exchanger and precooler, where the incoming air stream is chilled by removing heat to the water stream. The water stream is then circulated through the reheat heat exchanger, where the water stream is again cooled by removing heat to the cool dry air exiting the water extraction heat exchanger. Finally, the cooled water stream is circulated through the water filter to a three way valve, that directs water flow either to a dispenser or back to the water storage tank.

A method and apparatus to maximize spark plug life in pre-chamber spark plugs operating with ultra-lean mixtures and / or elevated engine BMEP is presented. Electrode erosion is reduced by spreading discharge energy over a wider surface area, maintaining fuel concentration in the spark gap, controlling gas static pressure during discharge, and maintaining safe electrode temperature. Energy is spread via a swirling effect created by periphery holes in an end cap, resulting in a lower specific energy discharge at the electrodes. Divergently configured electrodes reduce the spark voltage at high operating pressures and the energy required for ignition. The flow field generated at the electrodes prevents electrical shorts due to water condensation and avoids misfire. The center electrode insulation provides an effective heat transfer path to prevent electrode overheating and pre-ignition. The volume behind the electrodes provides a volume for burnt products from previous combustion cycles and leads to more reliable ignition.
