Title: Air-fuel ratio control device for internal combustion engine
Inventor: NADA MITSUHIRO
IPC: F02D41/14
Filed: 1990-06-20
Abstract: PURPOSE:To improve controllability regardless of the degree of warming of a three way-catalytic converter by setting integral speed for calculating storage term of the correction amount of an air-fuel ratio greater, when the three-way catalytic converter is in a cold state. CONSTITUTION:An air-fuel ratio sensor 15 is installed to an exhaust pipe 14 in the downstream side of a three way catalytic converter 12 to output different electric voltages depending on whether the concentration of oxygen in exhaust gas is on rich side or in lean side with respect to the theoretical air-fuel ratio. A control circuit 10 inputs output of the air-fuel ratio sensor 15 to perform proportional control and integral control, and calculates a coarse control term and a storage term of the correction amount of air-fuel ratio. Further, the control circuit judges the warning state of the three-way catalytic converter 12 by means of the output value of the storage term, and when it is judged that the three-way catalytic converter is in a cold state, the control circuit sets integral speed for use in integral control of calculation of the storage term greater than that in a case where the three-way catalytic converter is judged to be not in a cold state. Thus, the response of air-fuel ratio feedback system becomes faster, and emission is reduced even when the three-way catalytic converter 12 is in a cold state.

Title: Controller of vehicular automatic transmission
Inventor: HANAWA ATSUSHI
IPC: F16H61/04
Filed: 1993-06-04
Abstract: PURPOSE:To decrease shock to be generated in connection with the formation of a forward gear stage by providing an operation position detecting means for detecting the fact that a shift lever is operated and an engagement control means for starting the release of a second clutch element and the engagement of a third clutch element. CONSTITUTION:A high speed stage clutch C2 becomes in the half engaged state until a one-way clutch 102 arranged in series with a low speed stage brake B2 is completely engaged, that is, until the load torque of the one-way clutch 102 becomes negative, and the inertia torque to be generated during the engagement of a forward clutch C1 is absorbed by friction of the high speed stage clutch C2. Thereby the rising of the torque of a second output shaft 96, namely, the torque to be transmitted to a driving wheel 26 becomes relatively low, moreover the fluctuation of the torque becomes smooth. Moreover the fluctuation of the rotational speed of an engine 10 becomes also smooth. Accordingly, the shock to be generated in connection with the formation of a forward gear stage is decreased in squat control when a shift lever is operated.

Title: Premixed fuel injector and its centerbody
Inventor: KORZENDORFER JOHN J
IPC: F23R3/28
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To provide a premixed fuel injector in which different size changes due to a thermal expansion can be allowed. SOLUTION: An insert 40 is solidly fixed at a shell 38 of a centerbody 32. A fuel supply tube 42 is solidly brazed with the shell 38. The tube 42 is spirally bent in order to allow different size changes. Since there is no slip between the shell 38 and the insert 40, a leak due to abrasion does not occur, thus secondary air is correctly supplied. When the shell 38 is expanded against the tube 42, since the insert 40 does not retreat into the inside of the shell 38, a state in which flame flows into the inside of the shell 38 can be prevented. The curve of the shell 42 is set so that the natural frequency thereof becomes considerably larger than the frequency that is received during the time of operation of an engine.
