摘要:
An apparatus includes a processing apparatus that processes raw material in an airtight state, an accommodation section that accommodates the raw material, a first feeding path that is provided outside the processing apparatus and receives the raw material from the accommodation section, and a second feeding path having upstream and downstream ends that are outside and inside the processing apparatus, respectively. The second feeding path receives the raw material from the first feeding path. The apparatus also includes a joint section that separates and joins the first path and the second path, and a closing section that is positioned in the second path closer to the processing apparatus than the joint section and maintains the processing apparatus, and the second path in an airtight state when the joint section separates the first path and the second path.

Disclosed is a basic air-fuel ratio adjustment method and an apparatus for an internal combustion engine. The adjustment of the basic air-fuel ratio is performed by measuring a signal level corresponding to the level of an air-fuel ratio compensation signal of the engine while the feedback control operation for compensating an error of the air-fuel ratio of the engine is being stopped, by measuring the average level of the air-fuel ratio compensation signal when the feedback control is in operation, and by adjusting the means for presetting the basic air-fuel ratio of the air-fuel mixture fed into the engine so that the difference between the measured signal level and the measured average signal level becomes equal to a predetermined value. Thus, the adjustment of the basic air-fuel ratio can be very easily performed. Furthermore, a high accuracy of the adjustment can be easily obtained.

An improved fuel control apparatus for installation on an automobile engine equipped with an electronically controlled fuel injection system and a catalytic exhaust gas purifying system to prevent excess uncombusted fuel from being carried over into the catalytic purifier and burning therein with a resultant damage thereto. The apparatus essentially comprises a plurality of solenoid valves each associated with one of a plurality of fuel injection nozzles, a device for alternately energizing the solenoid valves to close to selectively stop the supply of fuel to one of the fuel injection nozzles upon elevation of the purifier temperature above a predetermined level, and a device for detecting the temperature of the catalytic purifier and transmitting only in case of elevation of the purifier temperature above a predetermined level a signal which enables the solenoid valve energizing device to function.
摘要:
There is provided an electronically controlled fuel injection system comprising a temperature fuel enrichment circuit for generating, in accordance with the output signal of an internal combustion engine temperature sensor, an output signal corresponding to a temperature fuel enrichment characteristic to provide the required fuel enrichment for cold operation, and fuel injection means for injecting an increased quantity of fuel in accordance with the output signal of the temperature fuel enrichment circuit. The system is additionally provided with a revolution compensation circuit for generating a revolution signal corresponding to the number of engine revolutions per minute for continuously decreasing the temperature fuel enrichment characteristic of the temperature fuel enrichment circuit in accordance with increase in the number of engine revolutions per minute. In this way, an improved fuel consumption characteristic is ensured during the warmup period and the underfeeding of fuel under the idling operation is eliminated, and moreover the fuel enrichment is smoothly accomplished to suit changes in the driving conditions of the vehicle.

Brazed product obtained by brazing a metal and ceramic according to a brazing method of high production rate that realizes uniform brazing material composition at brazed sites, thereby enhancing junction reliability and that is free from problems such as deterioration of working environment by malodor. There are also disclosed a ceramic part and metal part for use in the production of the brazed product. The brazed product is produced by applying a binder to brazing site of at least one of a metal part made of a metal and a ceramic part made of a ceramic; spreading active silver braze powder and fixing the same thereto; overlapping the brazing site with the bonding face of the counterpart member; and heating them in a furnace to melt the active silver braze powder and brazing therewith. The parts for brazing of the present invention are a ceramic part and a metal part having a binder applied onto brazing site of at least one of the metal and ceramic and having active silver braze powder spread on and fixed to the binder.
摘要:
A combustion process sensor for detecting combustion processes occurring in a combustion chamber of an engine has a generally tubular mounting casing to be screwed into a threaded hole in the combustion chamber wall and a quartz-glass rod axially extending in the mounting casing and held in position therein. The casing includes two axially aligned generally tubular members rigidly secured together at their own ends. The quartz-glass rod has a first portion remote from a sensing end thereof adapted to be exposed to combustion flame in the combustion chamber, and a second portion between the first portion and the sensing end. The first portion is secured to one of the two tubular members of the casing, while the second portion is supported from the casing only by a vibration damping material disposed in engagement with the outer peripheral surface of the quartz-glass rod and the inner peripheral surface of the casing.
