Title: System and method for detecting valve-related trouble state of internal combustion engine
Inventor: LEWANDOWSKI EDWARD J
IPC: F02D13/02
Filed: 1999-12-17
Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for detecting a trouble state to avoid a serious damage to an engine by detecting the valve-related trouble of an internal combustion engine with high-precision and at a proper timing. SOLUTION: A system and a method for detecting a trouble state utilize an intake air temperature at each of a plurality of the cylinder parts of an engine (52). An average value (54) of a plurality of intake air temperatures is compared (56) with each of individual temperatures at pitches of discrete-time increment. A rate of change to an average temperature value of intake temperatures is evaluated (58) and it is decided whether a valve-related trouble state occurs.

Abstract: PROBLEM TO BE SOLVED: To drive a front wheel accelerated stably at turn time, shorten a turn time, by additionally equipping a front wheel accelerating mechanism with a cost reduced, in a power agricultural machine of constitution switching from a four-wheel drive to a rear two-wheel drive when a car body is turned. SOLUTION: In a power agricultural machine of tractor or the like, a route making power of an engine 11 branch from a gear-type transmission 22 to drive a front wheel 20 and a route transmitting power of a hydraulically- operated transmission 31 to drive the front wheel 20 are provided. In the route driving the front wheel 20 from the gear-type transmission 22, a 4WD clutch 28 is provided. This constitution is formed such that when a car body is turned, first the 4WD clutch 28 is disconnected, power from the gear-type transmission 22 is interrupted, and then by power of the hydraulically-operated transmission 31, the front wheel 20 is driven. In this way, tangling of power of both the routes can be prevented.

Abstract: PROBLEM TO BE SOLVED: To enable even a wafer of large diameter to be etched uniformly at a high etching rate by a method wherein wafers are arranged in an etchant in a direction vertical to their surfaces making their main surfaces vertical in a position, and the adjacent wafers are rotated in opposite directions respec tively. SOLUTION: The peripheral edge of a wafer A5 whose center is offset by (d) from that of a wafer B6 is supported with a main roller 1 and the large diameter part 4d of a sub-roller 4, the peripheral edge of the wafer B6 is supported with a second main roller 2 and the large diameter part 3d of a second sub-roller 3 at right angles with their main surfaces. When the first main roller 1 and the first sub-roller 4 are rotated in a positive direction and the second main roller 2 and the second sub-roller 3 are rotated in an opposite direction, the wafers A5 and B6 are rotated in opposite directions, respectively. Therefore, the momentum of etchant is canceled with each other at a center between the wafers A5 and B6, so that etchant is easily circulated between the wafers A5 and B6.
