Turbulent jet ignition pre-chamber combustion system for spark ignition engines
ActiveUS8857405B2High-drive cycle (part load) fuel economyThermal efficiencyElectrical controlInternal combustion piston enginesCombustion systemCombustion chamber
An ignition system for an internal combustion engine having at least one combustion chamber where the ignition system includes a housing, an ignition device, an injector, and a pre-chamber having a nozzle disposed spaced from the proximal portion of the pre-chamber. The igniter portion of the ignition device and the nozzle of the injector are operatively supported in the proximal portion of the pre-chamber and disposed flush therewith. The igniter portion ignites the fuel in pre-chamber such that partially combusted pre-chamber products are forced through orifices in the pre-chamber nozzle and extinguish, but dispersed through the combustion chamber so as to ignite the main fuel charge therein.

Method and apparatus for controlling ventilation systems
ActiveUS8939827B2Increase speedShorten speedMechanical apparatusLighting and heating apparatusMotor speedEnergy recovery ventilation
An energy recovery ventilation system is described which allows for continuous fan speed control through pulse width modulation of direct current fans. The energy recovery ventilation described is capable of fine motor speed control without the disadvantages of high noise, low efficiency and a fixed number of speeds present in commonly-used speed-varying techniques used with alternating current (AC) fans. This may be accomplished through the use of direct current (DC) fans and pulse width modulation. A controller is used to optimize the ventilation and energy efficiency of the system through the use of several temperature sensors. The energy recovery ventilation also provides a control process for self-optimization of the energy recovery ventilation, in case the supply and exhaust airflows are unequal. An unbalance may be detected by calculating the thermal efficiencies of the exhaust and supply airflows.

A control apparatus for an internal combustion engine is provided. The control apparatus includes an ECU. The ECU is configured to change, in a stepped manner, an air-fuel ratio of the internal combustion engine so as to change over a combustion mode of the internal combustion engine between lean combustion and stoichiometric combustion, when an operating point of the internal combustion engine satisfies a first changeover condition that is defined by a rotational speed and a torque of the internal combustion engine. The first changeover condition is defined by the rotational speed and the torque that correspond to a predetermined intake air amount at which a thermal efficiency of the internal combustion engine is maintained before and after changeover of the combustion mode.

A ceramic green wavelength conversion element (120) is coated with a red wavelength conversion material (330) and placed above a blue light emitting element (110) such that the ceramic element (120) is attached to the light emitting element (110), thereby providing an efficient thermal coupling from the red and green converters (330, 120) to the light emitting element (110) and its associated heat sink. To protect the red converter coating (330) from the effects of subsequent processes, a sacrificial clear coating (340) is created above the red converter element (330). This clear coating (340) may be provided as a discrete layer of clear material, or it may be produced by allowing the red converters to settle to the bottom of its suspension material, thereby forming a converter-free upper layer that can be subjected to the subsequent fabrication processes.
