Methanol-Gasoline 混合燃料使用機關의 點火時期에 代한 性能考察 = A Study on Engine Performance according to Spark Timing Advance using Methanol Gasoline Fuel Blends.

다국어 초록 (Multilingual Abstract)

In this paper, we were studied engine performance, heat dissipations and mechanical efficiency by means of measuring fuel consumption, engine torque and cooling water consumption of engine used methanol gasoline fuel blends according to spark timing advance. And we were measured Carbon Monoxide (CO) and Hydro Carbon (tIC) of engine.
Engine spark timing advance angle were changed from 10° to 60° at 10° interval, and methanol gasoline fuel blends were from 10% to 50% at 10% interval.
From the above investigated, the results were abtained as following.
1. Fuel consumption ratio become minimum and brake horse power become maximum at point of spark advance nearby before 'fop Dead Center 30°.
2. Mechanical efficiency and quantity of heat dissipation become maximum at point of spark advance nearby before Top Dead Center 40°.
3. As methanol contend in fuel increased, CO emission decreased, and HC emission is slowness to methanol gasoline mixture ratio 30%.
