More specifically, it is a fuel oil containing dimethyl acetal as an active ingredient, has good ignitability, and contains extremely few harmful components in exhaust gas.
［従来の技術］
ディーゼルエンジンには、軽油、Ａ重油などの鉱油系の
燃料（以下単に鉱油燃料と称す）が使用されいている。[Prior Art] Mineral oil fuels (hereinafter simply referred to as mineral oil fuels) such as light oil and A heavy oil are used in diesel engines.
ディーゼルエンジン用燃料には、着火性が良好であるこ

一般に鉱油燃料はディーゼルエンジン用燃料としては、
着火性は満足されているが、黒煙が多いなど、排気ガス
抑制の対策にはまだ解決課題が残されている。Mineral oil fuel is generally used as fuel for diesel engines.
Although the ignitability has been satisfied, there are still issues to be solved in terms of exhaust gas control measures, such as a large amount of black smoke.
黒煙の発生を抑制するためには、メタノールを燃料とす

している。In order to suppress the generation of black smoke, it has been proposed to use methanol as fuel, but using methanol fuel solves the problem of exhaust gas, but the cetane number is about 3.
It has poor performance as a fuel, such as poor ignitability, low calorific value, hygroscopicity and corrosivity, and poor compatibility with mineral oil, making it difficult to use as a mixed fuel. .

成した。[Problem to be solved by the invention] In order to solve the above-mentioned problems, many attempts have been made to improve the combustion system and structure of diesel engines. It is an important issue to develop a fuel oil for diesel engines that has the following characteristics, and the present inventor has completed the present invention after repeated research on this subject.

ある。[Means for Solving the Problems] The present invention provides a diesel engine fuel oil characterized by containing dimethyl acetal as an active ingredient and containing 50 to 100% by volume of dimethyl acetal based on the total amount of mineral oil. This is a fuel oil composition for a diesel engine, which is a mixture of mineral oil and dimethyl acecool.
本発明のディーゼルエンジン用燃料油の有効成分である
ジメチルアセタール（以下ＤＭＡと呼ぶことがある）は

料として価値が高い。υ-L, I'1m Dimethyl acetal can be easily synthesized from methanol, and raw materials are easily available. DMA has a cetane number of 41~
42 and has excellent ignitability comparable to mineral oil, and has an appropriate viscosity and boiling point, so it can be used as a fuel for diesel engines without any problems. Surprisingly, compared to mineral oil, it can reduce the amount of black smoke generated by more than 90%, and the amount of nitrogen oxides (No.) in the exhaust gas is also extremely low. In addition, even when the engine load changes, black smoke generation can be maintained at an extremely low level.This point is the biggest difference from mineral oil, and it is highly valuable as a fuel for diesel engines.

ことができる。Furthermore, DMA has good compatibility with mineral oil and forms a uniform fuel composition in any proportion, so it can be used in combination with mineral oil. When used in combination with mineral oil, the composition preferably contains 50 to 100% by volume of DMA based on the mixture. If the DMA content is 50% or less, the effect of suppressing the amount of black smoke and NO8 generated cannot be sufficiently exhibited.There is no particular upper limit for the DMA content in the composition.
Of course, it is possible to use only DMA, and it is preferable to use more DMA in terms of black smoke and No.
Taking into account the price, amount of heat generated, distillation properties, viscosity, etc. of A and mineral oil, it can be used as a composition with a mixing ratio suitable for the purpose of use.
ＤＭＡと混合する鉱油としては、軽油、へ重油、灯油な

In particular, when used as a fuel for a collision-diffusion stratified charge combustion engine, it not only suppresses black smoke but also reduces N08 emissions to 1/3 to 1/3 that of mineral oil.
Reduce it to 1/4. In particular, the effect of suppressing NO is particularly noticeable under operating conditions where the engine load is high.

損うことなく、Ｎ０８とスモークを大巾に低減できる。As is clear from the results in Table 5, when the engine is operated under one condition that generates the same output, the NOo in the exhaust gas is approximately 1/2 that of dimethyl acetal, which is the fuel oil of the present invention, compared to heavy oil A. Regarding smoke, with heavy oil A, the amount generated increases rapidly as the load increases, whereas with dimethyl acecool, the amount was undetectable. That is, using dimethyl acetal as a fuel in a collision-diffusion stratified air charge engine can significantly reduce N08 and smoke without sacrificing thermal efficiency.

条件での効果が大きい。When the DMA of the present invention is used in a collision-diffusion stratified air charge engine, the effect of preventing the generation of smoke and NO is more pronounced than when it is used in a direct injection engine (Figs. 1 and 2). Almost zero, NOx is also very effective under severe conditions.
