摘要： A diesel fuel injection nozzle and holder assembly includes a tubular nozzle holder carrying a nozzle on one end and defining, in combination therewith, a storage chamber for receiving successive charges of fuel under pressure via a check valve mounted therein. A needle valve, complete with a stem, mounted in the storage chamber is urged by a first spring toward a position for closing spray orifices in the nozzle. Disposed opposite to the end of the needle valve stem, a yieldable abutment is biased by a second spring toward the stem and normally retained a preassigned distance away therefrom. When acted upon by each pressurized fuel charge trapped in the storage chamber, the needle valve is unseated to open the spray orifices against the force of the first spring if the fuel pressure is relatively low, and against the resultant of the forces of the first and second springs if the fuel pressure is higher.

摘要： Maintenance due times of components of a machine are determined according to the status of user-performed in-house maintenance and according to the occurrence of abnormalities during machine operation. A subtraction point (20 points) associated with an abnormality (overheating) detected during machine operation is subtracted from the score (80 points) of a corresponding component (engine) in the machine. An addition point (50 points) associated with the type of maintenance (overhaul performed by in-house maintenance) indicated in maintenance information is added to the score (80 points). Thus, at the time where the value resulting from subtractions from and additions to the score for that component (engine) reaches a prescribed value (10 points) indicating maintenance due time, it is determined that the maintenance due time for that component (engine) has been reached.

摘要： Only snapshot data necessary for monitoring faults are collected from machine such as vehicles, allowing faults to be more accurately monitored, and the amount of data and the memory storage volume at a monitoring station to be reduced. The values of a plurality of (A), (B), (C), and (D) operating parameters (engine rotational speed, lever operating position, vehicle speed, and tractive force) which change during the operation of the machine are sequentially detected for each machine. The fault detection history data are thus updated every time a fault (drop in engine oil pressure, overheating) is detected during the operation of the machine. Thus, when a fault (drop in engine oil pressure) is detected during the operation of the machine, it is determined on the basis of the history data whether or not to send to the monitoring station the sequential values of the operating parameters ((A) engine rotational speed, (B) lever operating position, (C) vehicle speed, (D) tractive force) from within a prescribed period of time (from 10 min. before to 5 min. after) around the point in time t0 at which the fault was detected. When it is determined that they should be sent, the type of detected fault (0001 (drop in engine oil pressure)), the values detected ((A) 2, (B) 3, (C) 3, (D) 2) at the time the fault was detected, as well as the sequential values of the operating parameters from within a prescribed period of time (from 10 min. before to 5 min. after) around the time the fault was detected are transmitted to the monitoring station. When it is determined that they should not be sent, on the other hand, the type of detected fault (0001 (drop in engine oil pressure)) and the values detected ((A) 2, (B) 3, (C) 3, (D) 2) at the time the fault was detected are sent to the monitoring station.

摘要： The present invention is a method of controlling a fuel injection apparatus for an internal combustion engine, and is capable of preventing the breakage of a component which is exposed to high-temperatures, such as an exhaust manifold. To this end, a first set temperature and a second set temperature, higher than the first set temperature, are set in advance, and a temperature of exhaust gas from an internal combustion engine (1) is detected. The number of occasions at which the temperature of the exhaust gas exceeds the first set temperature and the lengths of time during which the temperature of the exhaust gas has exceeded the second set temperature are totaled respectively, and either when the total number of occasions exceeds a predetermined number of occasions or when the total of the lengths of time exceeds a predetermined length, at least one of the following actions are taken: giving an alarm, reducing a fuel injection rate and changing the injection timing.

摘要： An injection valve assembly for spraying fuel into a diesel engine by receiving accurately metered charges of the fuel under pressure from an engine-driven jerk pump. The fuel inlet of the valve assembly communicates via a check valve with a storage chamber, where each incoming charge of pressurized fuel is stored temporarily. The fuel outlet of the valve assembly, in communication with the storage chamber, is normally closed by a spring-biased needle valve member. Upon full accumulation of each fuel charge in the storage chamber the check valve automatically closes the fuel inlet thereby causing the needle valve member to be displaced under the fuel pressure against the bias of the spring and hence to open the fuel outlet. Another embodiment employs two needle valve members, one for the on-off control of communication between the storage chamber and the fuel outlet, and the other for the on-off control of the fuel outlet.
