Title: Leak current probing device
Inventor: YOSHIDA HIDEMICHI
IPC: G01R31/08
Filed: 2000-09-27
Abstract: PROBLEM TO BE SOLVED: To detect surely a leak current by compensating errors in spite of existence of the detection errors and the difference between detection accuracies of two current detection means, and to improve workability of a clamp in a probing work. SOLUTION: Two current detection parts 2a, 2b are clamped simultaneously on the same voltage phase wiring route 10a, and the difference between each current value detected from the two current detection parts 2a, 2b is operated by a difference operation part 6, and adjustment is executed so as to remove the difference and to square each current value by adjustment parts 5a, 5b, and then, while one current detection part 2a is clamped on the voltage phase wiring route as it is, the other current detection part 2b is clamped on the earthing wire side and the difference is detected. Therefore, a probing action can be executed in the state where mutual errors are adjusted and squared so as to be compensated each other, and existence of the leak can be judged from the difference of the relative detection.

Title: Combustion control device for internal combustion engine
Inventor: TAKAKUWA EIJI
IPC: F02P17/12
Filed: 2000-09-29
Abstract: PROBLEM TO BE SOLVED: To improve ignitionability by avoiding over-rich of atomized fuel fed in a combustion chamber of a direct cylinder injection engine and reaching an ignition plug. SOLUTION: When a flame is formed between spark gaps of the ignition plug in the direct cylinder injection engine and if a combustion ion output is changed from presence to absence in an interval from the ignition start to the top dead center(TDC) and the frequency of a rich mode in changing the combustion ion output to the presence after TDC exceeds a prescribed value, it is determined to be over-rich. In this case, the fuel injection quantity to the direct cylinder injection engine is correctively reduced to avoid over-rich. When the direct cylinder injection engine is a stratified combustion in a high-load and high-rotation range, the increase in the atomized fuel reaching the ignition gaps of the ignition plug increases to surely avoid the over-rich combustion state and the optimal combustion state is attained to improve the output and to reduce the unburnt HC.
