A water jacket in the turbo-charger is positioned at the same level or higher than a water jacket in an engine cylinder head. The turbo-charger cooling water circulation passageway includes a water volume or tank positioned at a level higher than the turbo-charger cooling portion, and the volume or tank is connected to a cooling water reservoir tank via a pressure relief valve which is opened when pressure in the volume or tank exceeds a predetermined value to supply cooling water to the volume or tank.

An intake system for internal combustion engines comprises a throttling system mounted in an intake pipe between a fuel injection valve and an intake manifold, the throttling system including a stationary valve body fixed in the intake pipe in opposed relation with the injection valve and a hollow valve body mounted in the intake pipe for movement in the axial direction of the intake pipe. The hollow valve body has a downwardly converged inner wall surface surrounding the stationary valve body to define therebetween valve opening of variable opening area. The stationary valve body includes a frusto-conical portion and a cylindrical portion, of which lower edge is in the form of sinusoidal wave to cooperate with the hollow valve body in producing the valve opening of gradually increasing opening area.

An additional air supply system for adjusting the air-fuel ratio of a mixture includes the improved control unit for actuating, at two different speeds, a drive motor of a bypass valve disposed in an additional air supply path. The control unit is provided with an air-fuel ratio discriminating circuit for generating high and low level signals by comparing a detected air-fuel ratio with the stoichiometric ratio, and an actuating circuit for producing pulse signals at each instant of inversion of the signal levels of the air-fuel ratio discriminating circuit in such that for a predetermined period from the instant of inversion a high frequency pulse signal is produced and then a low frequency pulse signal is produced for the remaining period until the next inversion. Since the pusle signals having two different frequencies are applied to the drive motor of the bypass valve, the bypass valve is drived at a fast speed to a predetermined amount of opening or closing and then moved slowly until the next inversion of the signal level.
摘要:
PSC-A is a new serological common antigen to Pseudomonas aeruginosa having very low toxicity, and highly effective for protecting infection by any of the serotypes of Pseudomonas aeruginosa. PSC-A can be used as the active component in a pharmaceutical agent for protecting Pseudomonas aeruginosa infection.
摘要:
A fuel injection type internal combustion engine provided with a pressure regulator for controlling a constant difference between a pressure of fuel supplied to the injector and a pressure of the intake system at the position where the injector is mounted. A tank is arranged for storing a positive pressure obtained while the engine is operated. A switching valve is arranged for connecting the tank with the pressure regulator when the engine is started when hot. Due to the operation of the regulator for maintaining the constant pressure difference, the pressure of the fuel supplied to the fuel injector is increased, making it difficult for the fuel to vaporize. Thus, preventing a so-called vapor lock.
摘要:
A hot isostatic pressing apparatus including a high pressure container having an opening at least at one end thereof for loading and unloading materials or products being formed. The high pressure container is internally provided with a heat insulator and a heater. A container holding frame has an open space substantially at the center thereof for releasably holding the upper and lower ends of the high pressure container during the hot isostatic pressing stage of the operation. The container holding frame is movably supported at one side thereof on a stationary structure for movements toward and away from the high pressure container.
摘要:
An intake system for an internal combustion engine comprises a throttling system mounted in an intake pipe between a fuel injection valve and an intake manifold, the throttling system including a stationary valve body fixed in the intake pipe in opposition to the injection valve and a hollow valve body mounted in the intake pipe movably in an axial direction of the intake pipe. The hollow valve body has a downwardly converged inner wall surface surrounding the stationary valve body to define therebetween valve opening of variable opening area. The axial movement of the hollow valve body causes the change in the opening area of the valve opening to control an amount of air-fuel mixture charged therethrough into the engine.
摘要:
An air flow amount adjusting system produces an air-fuel mixture of a desirable air-fuel ratio by controlling the direction of movement of a bypass valve mounted in an additional air supply pipe adapted to supply additional air into either the intake system or exhaust system of an internal combustion engine in accordance with an output signal produced from a gas sensor mounted in the exhaust system of the engine and indicative of the air-fuel ratio of the mixture supplied to the engine. A two-level mode signal whose threshold corresponds to the desired air-fuel ratio is produced in accordance with the output signal of the gas detector. After the two-level mode signal has changed from one level to the other level, the movement of the bypass valve is stopped for a certain period of time. If desired, the stopping period of the bypass valve may be changed in accordance with the temperature of the engine.
