ある。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a liquefied petroleum gas fuel supply device for supplying a mixture to an internal combustion engine, and particularly relates to a liquefied petroleum gas fuel supply device installed upstream of a throttle valve. It is.

いる。
In the case of a fuel injection device that uses gasoline as fuel for an automobile engine, the fuel pressure in the fuel tank is approximately atmospheric pressure, so the fuel is pressurized by a fuel pump and supplied to the fuel injection valve. In order to keep the fuel pressure constant at this time, a fuel pressure regulator is used to keep the differential pressure before and after the fuel injection valve constant, and conventionally a method has been adopted in which the fuel is injected downstream of the throttle valve.

ツトルバルブ下流に噴射する方式は実用すること
がむづかしい。 However, liquefied petroleum gas (hereinafter referred to as LPG) fuel differs in fuel composition depending on the season and region in which it is sold, and due to differences in fuel composition and seasonal temperature differences, the fuel vapor pressure can vary from 0 to 20 kg/cm 2 at a maximum. It changes up to about G. In order to solve this problem, even if the fuel pressure is increased to a predetermined value using a fuel pump only when the pressure is low, the fuel pressure will vary widely between 5 and 20 kg/cm 2 G. Furthermore, in the case of throttle valve downstream injection, the pressure downstream of the fuel injection valve fluctuates rapidly and frequently, so it is very difficult to control both fluctuations. For these reasons, it is difficult to put the injection method downstream of the throttle valve into practical use.
そこで、スロツトルチヤンバーのスロツトルバ

るようにしたものである。 Therefore, a method of injecting LPG fuel by providing a fuel injection valve upstream of the throttle valve of the throttle chamber has been studied in the past, and the applicant of the present application previously filed an application as U.S. Pat. No. 57-138954. This detects the upstream fuel pressure of the fuel injection valve, calculates the ratio to the reference fuel pressure, and corrects the valve opening time of the fuel injection valve.

れがある。 However, when LPG fuel is injected directly upstream of the throttle valve, the heat of vaporization of LPG cools the intake air and the throttle chamber, causing water vapor in the intake air to freeze on the throttle valve and throttle shaft. . As a result, there is a risk of unstable air flow control and malfunction of the throttle valve.

However, when the engine is stopped, it is stopped by a solenoid valve 9. In the fuel reservoir 8, the fuel pressure after being pressurized by the fuel pump 7 is measured by a pressure transducer 14, and the temperature is measured by a temperature sensor 15, which are sent to an electronic control device 16 as an electrical signal. Further, since the suction negative pressure is obtained by the suction negative pressure sensor 12, and the engine rotation speed is detected by the rotation speed sensor 13 and inputted to the electronic control device 16, first, the basic opening of the fuel injection valve 10 is performed. A valve time T s is calculated.

Calculated. These three types of correction coefficients α, β, γ
The valve opening time of the fuel injection valve 10 is calculated by multiplying the basic valve opening time Ts by the basic valve opening time Ts. This valve opening time output signal operates the drive circuit 19 to open the fuel injection valve 10. In this way, LPG fuel corresponding to the amount of intake air is injected into the vaporization chamber 21 of the vaporization device 11.

る。 In general, if non-volatile components such as oil mixed in LPG fuel oxidize and adhere to the passage of the throttle chamber 3, the throttle shaft, etc., it will cause malfunctions and disrupt flow control, so countermeasures are required. In this embodiment, these tars are separated in the vaporizer 11 on the upstream side of the throttle chamber 3, so there is no need to worry about this. Further, since completely vaporized LPG gas is supplied into the throttle chamber 3, the vicinity of the throttle valve 4 does not become low temperature and malfunction occurs. Furthermore, since the supplied fuel is supplied upstream of the throttle valve 3, it is not affected by the engine's suction negative pressure, etc., and it is possible to supply an accurate amount of fuel with good distribution.

ない等の効果をもつている。 The LPG fuel supply system of this embodiment measures the temperature and pressure of the LPG liquid, injects the amount of fuel appropriate to the operating conditions from the fuel injection valve, vaporizes it in the vaporizer, and throttles the throttle chamber. Since it is ejected upstream of the valve, tar in the fuel is not brought into the throttle chamber, the temperature around the throttle valve does not become low, and it is not affected by suction negative pressure. A suitable amount of fuel can be supplied with good distribution, and since the vaporizer is separate from the throttle chamber, there are fewer design restrictions.
