Abstract

PURPOSE:To control the supercharging pressure for an engine in an optimum condition at all times by a method wherein in a device for opening an exhaust bypass passage bypassing a turbine section on the base of the output of a supercharging pressure detecting section, the supercharging pressure detecting section is operated in accordance with the operation condition of the engine. CONSTITUTION:When the supercharging pressure detecting section D adopted to detect the supercharging pressure in a compression section C of the turbo-supercharger detects a supercharging pressure higher than a predetermined value, a bypass valve in the exhaust bypass passage bypassing the turbine section (not shown) through a control rod L is opened to thereby prevent the supercharging pressure from rising abnormally. In the case of such device, a three-way electromagnetic valve 1 is provided within a pipe P1 connecting the output side Co of the compressor section C and the supercharging pressure detecting section D. The valve 1 is provided with two valve members 1a and 1b which open and close independently of each other and the output side of the valve body 1b is connected to the input side of the compressor section C by means of a pipe P2. Both of the valve members 1a and 1b are opened and closed in a desired cycle by the operation of an operation section 2 or in accordance with the operation condition of the engine.

That is, for a turbo engine, the absolute amount of supercharged gas is more important than the boost pressure, but since the absolute amount of gas varies depending on the temperature etc. even under the same direction, the safety a. Even if the boost pressure at which the system operates supplies a sufficient amount of air to the engine at a certain temperature, there is a drawback that as the temperature rises, a shortage of air occurs. This is the boost pressure at which the safety structure operates.

In this way, a part of the supercharged 9 air that was pressing the diaphragm d of the supercharging pressure detection aD through the pipe P1 is released according to the opening and closing cycle of the 1 magnetic square 1 m and 1b. Piping P1. Since the input side Ckv of the compressor C is released through the electric valve 1 and the low length fiP2, the pressure of the compressed air applied to the diaphragm d decreases, and the supercharging pressure at which the safety mechanism operates is relatively high. increases, and eventually a sufficient amount of air is supplied to the turbo engine. Therefore, in the above practical example, the opening and closing of electric i 1 sho 1 is controlled by M
Although my personal opinion is based on my own sense, the present invention is not limited to this, and various sensors such as an outside temperature sensor, an intake temperature sensor/seat, and a temperature sensor in the engine room are installed in the KCL turbo engine. The output of this sensor is toad! The opening/closing of the electromagnetic box 1 and the period thereof may be determined. In this way, the driver does not need to operate the volume 6 of the actuating section 2, which is more convenient. Therefore, this method is suitable as a method for controlling the supercharging pressure of an engine equipped with a turbocharger according to the operating state of the engine.
