Title: Multistage compression self-ignition internal combustion engine
Inventor: KINO MASATO
IPC: F02B19/02
Filed: 2008-09-08
Abstract: <P>PROBLEM TO BE SOLVED: To expand the operation output band of a compression self-ignition internal combustion engine and facilitate change over to other operation modes.  <P>SOLUTION: In a four-cycle compression self-ignition internal combustion engine using gasoline as fuel, an auxiliary chamber 103 is provided and a communication part to a main combustion chamber 106 is partitioned by a communication valve 105. A spark plug 104 and an intake valve for supplying air fuel mixture are provided in the auxiliary chamber. The communication valve is opened in an intake process, an intake valve 102 of the auxiliary chamber is opened at a later half of the process, rich air fuel mixture for plug ignition is supplied to the auxiliary chamber, and the communication valve is closed near CA corresponding to compression ratio 9. Compression further progresses in the main combustion chamber and front flame reaction starts. However, compression ratio is set to pressure before self ignition. Ignition is done by the spark plug of the auxiliary chamber near a top dead center. When pressure of the auxiliary chamber exceeds pressure of the main combustion chamber, the communication valve is opened, gas after combustion flows in the main combustion chamber, and air fuel mixture in the main combustion chamber is compressed again. Since front flame reaction progresses, ignition occurs in a short period of time and pressure rises, and the communication valve is closed.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To actualize diversity effect using an overreach signal on a multi-hop radio network, where a relay station performs batch transmission, even if a signal received by a relay station has an error.  <P>SOLUTION: The relay station 10 demodulates signals received from transmitting/receiving stations 20-1 and 20-2 once to perform error detection. When there is no error found through the error detection, a DF system is applied, but when an error is found, an AF system (providing that equalization processing is performed) is applied. Relay signals to which the respective systems are applied are subjected to analog modulated signal multiplexing, and transmitted together at a time. Further, the transmitting/receiving stations 20-1 and 20-2 directly receive signals transmitted from transmission sides, and perform maximum ratio composition of a desired signal received from the relay station and the direct signals. Weights used for the maximum ratio composition are changed according to a propagation path coefficient between two points and a relay state of a relay signal at the relay station. Then the signal having been subjected to the maximum ratio composition is demodulated.  <P>COPYRIGHT: (C)2010,JPO&INPIT
