Title: Fuel/water layer injection device
Inventor: TOSA YOZO
IPC: F02B77/08
Filed: 1992-10-30
Abstract: PURPOSE:To immediately stop water injection and prevent serious accident such as seizure of a fuel injection pump, when the injected water is going to flow in reverse to a fuel injection valve, due to a transient driving condition of engine or to failure in a water injection control valve. CONSTITUTION:A conductive member 101 electrically insulated from other line forming members is inserted into an injection line 8 between a fuel injection pump and a fuel injection valve through an insulating member 102, in a diesel engine, in which fuel and water are contained in layer in a cylinder so that they can be injected, by injecting water in a fuel path of the fuel injection valve in a period where fuel injection is not carried out. Excess reverse flow of injected water to the side of the fuel injection pump is detected by detecting an electrically conductive signal between the conductive member and the other line forming members, and the injected water is thus immediately stopped by a controller.

IPC: F02P5/152
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To suitably judge knocking so as to improve accuracy of judgment in a knocking judging device for an internal combustion engine which can perform stratified burning and so on. SOLUTION: A fuel injection valve 11 is arranged in the peripheral part of the inner wall surface of a cylinder head 4 in the vicinity of the first intake valve 6a and second intake valve 6b of an engine 1, and fuel from the fuel injection valve 11 is ejected directly to the inside of an air cylinder 1a. Also, a knock sensor 63 for detecting the knocking of the engine 1 is attached to the cylinder block 2 of the engine 1. In case that stratified burning is executed, a combustion speed is increased considerably in comparison with a case that homogenous combustion is executed, therefore, timing that knocking can occur is also hastened. On the contrary, in case that stratified burning is executed, an electronic control device (ECU) 30 sets a knocking judging period to an early time. Therefore, a judging period can be justified.

Title: Residual stress measuring method for columnar or cylindrical material
Inventor: JINBO YASUHIRO
IPC: G01L1/00
Filed: 1989-12-05
Abstract: PURPOSE:To obtain the residual stress measuring method which facilitates the operation, reduces the cost, and provides an accurate result and is wide in application range by setting L/D<=0.2 or L/D<=0.1 for stricter measurement accuracy, where L is the thickness of a thin plate formed by cutting the columnar or cylindrical material and D is the diameter of the thin plate. CONSTITUTION:The columnar or cylindrical material is cut into the discoid or hollow discoid thin plate and the residual stress of the columnar or cylindrical material is calculated from the residual strain values in the circumferential and radial directions of the thin plate. In this case, the thickness of the thin plate is so set the L/D <= 0.2. Further, when stricter measurement accuracy is requested, the thickness of the thin plate is so set that L/D <= 0.1. Thus, the thickness of the disk is limited in relation with its diameter to maintain or improve the measurement accuracy and this method is widely apply applied for the residual stress measurement of a finite-length columnar or cylindrical material.
