Description

Fuel saving apparatus for gasoline and LPG cars

The present invention relates to a fuel saving device for gasoline and LPG vehicles, and more specifically, to a state of fine mixed gas by firstly injecting a part of fuel (gasoline or LPG) into the air supplied to a surge tank through an air purifier. It is intended to provide a fuel saving device for gasoline and LPG vehicles that is made of fuel and then supplied to the combustion chamber to promote combustion, which increases output, saves fuel and minimizes pollution emissions.

In a gasoline or LPG vehicle engine, fuel and air supplied into a combustion chamber are made as shown in FIG. 1.

That is, the fuel supply device 1 is an injector in which the fuel (gasoline or LPG) in the fuel tank 2 is connected to the fuel supply pipe 6, the injection amount is adjusted by the ECU 4, and is fixed to the intake manifold 3a. (5) is supplied into the combustion chamber (3), and the air supplied from the air cleaner (7) supplies a surge tank (10) whose supply amount is controlled by the air supply hose (8) and the throttle valve (9). The amount of fuel and air supplied to the intake manifold 3a and supplied to the combustion chamber 3 by mixing the fuel injected into the injector 5 with an appropriate ratio (air 14.7: fuel 1) through the intake manifold 3a. The exhaust gas concentration is detected and adjusted by the oxygen sensor 11 electrically connected to the ECU 4 coupled to the exhaust manifold 3b, and the fuel tank (2) is connected between the fuel tank (2) and the surge tank (10). The canister vacuum hose 12 for supplying the boil-off gas generated in 2) is connected.

However, although the conventional fuel supply device 1 having the above-described configuration is supplied in a state in which fine dust and the like are filtered from the air supplied from the air cleaner 7, NO _X , SO _X , and CO _X which are combustion interference materials in the air. Since a large amount (about 80%) is included, there is a problem that the combustion efficiency is lowered. When the combustion efficiency is lowered as described above, the engine output naturally decreases, so the amount of fuel supplied to the intake manifold 3a is increased to compensate for this. There has been a problem that the amount of fuel used increases, and there has been a demand for the development of a technology that can reduce the fuel supply and increase the output while increasing the combustion efficiency.

In this regard, the present inventors have studied the present invention to solve all the problems occurring in the conventional fuel supply apparatus as described above.

In other words, the present invention improves combustion efficiency by oxidizing NO _X , SO _X and CO _X contained in the air supplied to the surge tank with an air cleaner, and minimizes the emission of pollutants in the exhaust gas, and from the fuel tank. Part of the supplied fuel is injected into the surge tank or the air supply hose supplying air to the surge tank so that the air in the surge tank is supplied to the combustion chamber in the form of fine mixed gas, thereby increasing the explosive force in the combustion chamber and reducing the fuel consumption. The present invention has been completed in view of the technical problem of the present invention to provide a fuel saving device for gasoline and LPG vehicles that can exhibit high power.
