Abstract(E)	Currently, even the small diesel engines are required to reduce CO₂ emissions toward carbon-neutral society. One of the methods to realize this would be to use alternative fuels. Therefore, this research focuses on a liquid which is called MCH (Methylcyclohexane), it is expected as one of the "hydrogen carriers" that can transport hydrogen from foreign country efficiently. MCH is produced overseas by adding hydrogen to the toluene, and the hydrogen is extracted after transport to the destination. However, there is significant energy loss in extracting hydrogen process from MCH. Therefore, it would be more hydrogen efficient use through MCH as fuel for the small diesel engines directly, rather than for power generation by extracting hydrogen, since it does not have that significant energy loss of MCH blended fuel in this research. MCH also has high potential for use as fuel, because it has sufficient calorific value on its own, it has low viscosity, it can be stored at room temperature and pressure, and it can use existing petroleum infrastructure [2, 3]. Moreover, MCH is low carbon number compared with the diesel fuel, it has the potential for reducing CO₂ emission from the small diesel engines. In this research, engine tests are conducted with MCH blended with the diesel fuel, and it will be reported the fundamental engine test as indicator diagram and thermal efficiency and CO, HC, smoke emissions. MCH would be applied to the diesel engine without any adjusting of itself. The results have been mentioned that the blending rate of MCH with 10% volume would be appropriate for the performance of the small diesel engine.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.
