SYSTEMS AND METHODS FOR COORDINATION OF SKIP-FIRE AND AFTERTREATMENT HEATER OPERATION TO MAINTAIN EXHAUST GAS TEMPERATURE
A system includes an aftertreatment system heater of an exhaust aftertreatment system coupled to an engine A controller coupled to the aftertreatment system heater is configured to determine a condition of an exhaust gas from an engine and compare the condition to a predefined threshold. If the condition of the exhaust gas does not meet the predefined threshold, the controller is configured to determine whether an engine operating condition is met for activating a cylinder deactivation operating mode for the engine. If the engine operating condition is met, the controller is configured to operate the engine in the cylinder deactivation operating mode by deactivating a cylinder of a plurality of cylinders. If the engine operating condition is not met, the controller is configured to activate the aftertreatment system heater to heat the exhaust gas.
Precombustion nitric oxide exchange chamber (NOEC)
An air intake apparatus for a combustion engine includes an air intake tube for receiving an unmodified ambient air stream from outside the engine. The apparatus includes a first stream modifier chamber for receiving the unmodified ambient air stream that includes a plurality of spark plugs operative to generate nitric oxide when electrically energized such that the unmodified ambient air stream is modified into a first modified air stream rich in nitric oxide. The apparatus includes a second stream modifier chamber positioned downstream from the first and including a GMX400 magnet in magnetic communication with the air intake tube that causes additional oxygen atoms from the first modified air stream to combine with the first modified air stream. The enhanced air stream travels downstream and is combined with fuel and combusted, an exhaust stream thereof having at least 20% less carbon dioxide than a traditional exhaust stream.

DEVICE FOR LOWERING THE POUR POINT OF CRUDE OIL OR HEAVY FUEL OIL
A device for treating crude oil or heavy fuel oil with a method that can lower the pour point to at least 0° C. Crude oil or heavy fuel oil treated thusly maintains this property for at least one year. The device for lowering the pour point of crude oil or heavy fuel oil uses a specific ionization method. The method is conducted by passing a heated medium through the main ionization device which is grounded and which includes three parallelly connected segments whereby each segment includes a protective copper tube inside which a protective insulating shell is situated, inside which a copper housing is situated. In each copper housing there is one cylindrical-shaped external core in which an internal core is placed, and the external core and internal core are manufactured as two different alloys by composition. Also described is a process for casting the external core and internal core.
