IPC: F02D15/04
Filed: 2011-02-18
Abstract: PROBLEM TO BE SOLVED: To provide a multi-cylinder internal combustion engine equipped with a variable compression ratio mechanism, which detects that actual mechanical compression ratio of each cylinder is not uniform by using an air-fuel ratio sensor disposed in an engine exhaust system without adding a sensor.SOLUTION: The air-fuel ratio sensor disposed in an exhaust system outputs an air-fuel ratio larger than an actual air-fuel ratio when a vaporized fuel is included in an exhaust gas. A deviation A between an output air-fuel ratio from the air fuel ratio sensor and an actual air-fuel ratio is greater as a concentration of the vaporized fuel in the exhaust gas is higher. When it is determined whether the actual mechanical compression ratio of each cylinder is uniform, the target mechanical compression ratio is reduced to control the variable compression ratio mechanism without changing an intake amount and a fuel injection amount and it is determined that the actual mechanical compression ratio of each cylinder is not uniform if the difference dA of output air-fuel ratio of the air-fuel ratio sensor to the exhaust gas of each cylinder before and after control is not uniform.

Title: Method and system for improving performance of inter-system handover
Inventor: MUELLER WALTER
IPC: H04W36/14
Filed: 2011-03-04
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the size of information elements of a handover command message between generations.  <P>SOLUTION: The size of certain information elements in the UTRAN RRC "HANDOVER TO UTRAN COMMAND" message is made small, by reserving a subrange of IE parameter values for exclusive use by User Equipment which is performing an inter-Radio Access Technology (RAT) handover to a UTRAN. The lowest values of scrambling code number or S-RNTI number is reserved for initial assignment to a UE performing a handover from one system network to the UTRAN. Upon completion of the handover procedure, the UTRAN can assign another scrambling code number or S-RNTI number to that UE. Consequently, by significantly reducing the size of the IEs, additional parameters may also be used in the same message.  <P>COPYRIGHT: (C)2011,JPO&INPIT
