and combustion characteristics. Therefore, the following subject should be
investigated for fundamental understanding if pure methanol or methanol–diesel blends were used in CI engines, especially in new technology CI
engines. The main subjects may be written as:
• Long-term endurance tests and any engine modifications
• Cold weather startability and cold start emissions
• Lubricity properties of methanol–diesel blends
• Corrosive properties of methanol and wear effects on the engine and
fuel system parts
• Engine tests at different engine operating parameters (effect of EGR,
compression ratio, etc.)
• Engine tests at different injection parameters such as multiple injection and injection timing
• Methanol–diesel fuel blends spray characteristics using different
injectors
• Knock production (noise level)
• Using cetane improvers for modifying ignition delay
• Optimum methanol–diesel blends at different engine operating
conditions
• The effect of exhaust aftertreatment use on regulated emissions
In addition to a combination of the above subjects, to investigate the relationships between the fuel properties and combustion, the physical and chemical
phenomena in the combustion chamber can be observed by using a highspeed camera system. This will provide valuable information on the nature
of combustion process to help the researchers and engine designers for their
future studies related to the fuel properties and methanol.
