Description of the Related Art In general, a compression ignition engine is used as a power source for industrial equipment or the like for driving a truck or an industrial vehicle which requires a large output because a high thermal efficiency is obtained.

液化石油ガスを使用することは実用的でなかった。On the other hand, liquefied petroleum gas has a low cetane number and poor ignitability. When liquefied petroleum gas is used as it is as fuel for a compression ignition engine, it is necessary to increase the compression ratio to 26 or more. However, at such a compression ratio, high thermal efficiency, which is the greatest advantage of the compression ignition engine, cannot be obtained, and noise and vibration are large, and it is not practical to use liquefied petroleum gas as fuel for the compression ignition engine. .

The present invention has been made in view of such a point, and an object of the present invention is to provide a technology that enables liquefied petroleum gas, which is regarded as clean fuel, to be used as fuel for a compression ignition engine.

By supplying the fuel into the combustion chamber of the compression ignition engine set at 3, the output and thermal efficiency equivalent to those when diesel oil such as light oil or heavy oil is used as fuel can be maintained, while generating black smoke.

At least one of nitrate ester, nitrite ester, organic peroxide, and azo compound is added and mixed in an amount of 0.1 to 6 vol%.

にするためである。Here, the upper limit of the compression ratio of the compression ignition engine is 2
The reason for setting to 3 is that the higher the compression ratio, the smaller the amount of the radical generator to be added to the liquefied petroleum gas. Because the frictional resistance in the valve system increases, the output efficiency decreases, and when the compression ratio decreases, the amount of heat generated during compression becomes insufficient. In order to be able to use in the range.

ては使用しにくくなるためである。The amount of the radical generator added is 0.1 to 0.1.
The reason for setting to 6 vol% is that if the amount of the radical generator added falls below 0.1% within the above compression ratio range, it becomes difficult to ignite even if liquefied petroleum gas is injected into the combustion chamber in a compressed state. If the amount of the radical generator exceeds 6%, the cost is more than 20% higher than the fuel cost when light oil is used, and it is difficult to use the fuel as a diesel oil alternative fuel such as light oil and heavy oil. That's why.

Normal butane to which 3 vol% of di-t-butyl peroxide (organic peroxide) was added as a radical generator was injected into a compression ignition engine set at 800 rpm, a plunger diameter of 13 mm, and a fuel injection timing of 26 degrees before top dead center. The thermal efficiency, the amount of black smoke generated, and the amount of carbon dioxide generated when used as were measured. As comparative examples, the combustion efficiency, the amount of black smoke generated, and the amount of carbon dioxide generated when light oil was used as fuel were measured. The results are shown in FIGS.

According to the above, it is understood that the thermal efficiency exhibits substantially the same efficiency as the case of light oil when the liquefied petroleum gas containing the radical generator is used as fuel. FIG. 2 is a graph showing the amount of black smoke generated. According to FIG. 2, when light oil is used as fuel, black smoke is generated over the entire area of the net average effective pressure,
When the pressure exceeds 0.5 MPa, the value rapidly increases. However, when liquefied petroleum gas containing a radical generator is used as fuel, almost no black smoke can be detected in the entire region.

According to FIG. 3, when the liquefied petroleum gas mixed with the radical generator is used, the use of the liquefied petroleum gas mixed with the radical generator is about 13% of that using the light oil in terms of carbon dioxide emission. It can be seen that the degree has decreased.

い。In the above embodiment, the description has been made of the case where normal butane is used as a diesel oil alternative fuel such as light oil or heavy oil. However, the alternative fuel is a mixed gas of liquefied butane and liquefied propane, or liquefied propane. You may. In the case of a mixed gas of liquefied butane and liquefied propane, a liquefied gas mainly containing butane containing 50% or more of liquefied butane is desirable from the relation of cetane number.

え、二酸化炭素の排出量も減少させることができる。According to the present invention, a mixture of liquefied petroleum gas and a radical generator in an amount of 0.1 to 6 vol% is used in a compression ratio of 11 to 2%.
By supplying the fuel into the combustion chamber of the compression ignition engine set at 3, the output and thermal efficiency equivalent to those when diesel oil such as light oil or heavy oil is used as fuel can be maintained, while generating black smoke. Not only can this be significantly reduced, but also the carbon footprint can be reduced.
