摘要:
A system for automatic charging pressure control using an exhaust gas turbocharger with a variably adjustable turbine cross-section and for automatic exhaust gas recirculation control in the case of an internal-combustion engine, particularly a diesel engine. An automatic control system has a first controller which has an output for the variation of the turbine cross-section of the exhaust gas turbocharger. The command variable for the automatic exhaust gas recirculation control in a first low load-rotational speed range is the air flow rate in the intake pipe. The command variable for the automatic charging pressure control in a second higher load-rotational speed range is the charging pressure in the intake pipe. For the automatic exhaust gas recirculation control, an exhaust gas recirculation pipe connects the exhaust gas pipe with the suction pipe. In the case of this system, for achieving the lowest possible pollutant emission while simultaneously minimizing fuel consumption, exhaust gas recirculation rates which are as precise as possible are defined in the lower load-rotational speed range, and a charging pressure which is as precise as possible is defined in the upper load-rotational speed range via a corresponding automatic control.

In a method for operating an internal combustion engine with exhaust gas purification system, a rich-burn mode of the internal combustion engine with a rich exhaust gas composition or a lean-burn mode of the internal combustion engine with a lean exhaust gas composition is set alternately, and the quantity of fuel which is introduced during a combustion cycle of the internal combustion engine is introduced by means of at least one preinjection, at least one main injection and at least one afterinjection.
摘要:
The present invention provides a standard network system, method and apparatus for processing and routing an emergency request or call (911) and its associated location information, including GPS location information where available, from a traditional telephone device, a wireless device (Cell telephone) or voice over IP (VoIP) device. When an emergency call is detected by a Communications Service Provider (CSP) such as a Telephone Company, VOIP Service provider, Wireless Service Provider, or Originating Caller, the calling party's telephone number or identifying network address is forwarded to the CSP's Service Location Identification System (SLIS) located with and connected to the CSP's communications network. The SLIS will receive from the CSP's network call processing or switching system, the caller's telephone number (ANI) or identifying network address (INA) such as an IP address, MAC address, SIP address, or any such unique identifier of a caller. This number or address is used as the primary search key into the SLIS database where the CSP has previously stored an address location record describing the physical location of the caller associated with the ANI, INA, or network element through which a call is processed that identifies the nearest network device to the caller. Once the SLS has retrieved the caller's nearest location information from its database the caller's voice and that location data, which may include Name, Address, Geographic Coordinates or any other type of location information available, is formatted into XML or the current data exchange mechanism and sent over a network connection to an Emergency Services Responding Service Provider (ESRP). This network may be a private or public IP, SS7 or any other type of network capable of conveying the ANI, INA and the associated location information to a Service Location Receiving System (SLRS) located with and connected to a county or city PSAP or some other type of ESRP.
