Diesel to Di-methyl Ether Engine Conversion
Undergraduate Engineering Physics Thesis - Design of Modifications to a Dual Fuel Engine utilizing DME as Pilot Fuel
Converted a 0.8L diesel SMART engine to operate on a dual fuel (methane and di-methyl ether) system.
The conventional high pressure diesel delivery system was subverted, as it was incompatible with the physical properties of DME. A pressure control valve used on the stock common fuel rail was welded shut to prevent intermittent dumping of fuel. The majority of the existing diesel delivery tubing was bypassed with high-pressure ¼ inch stainless steel tube capable of handling the 400 bar (5800 psi) from a pressurized DME sample bottle-nitrogen cylinder system.
Engine tuning & optimization, performance tests, long-term experimental setup, and in-depth data acquisition via TI-DAQ followed.
Developed skills in: High pressure fluid system design, internal combustion engine theory, TI DAQ hard/software.
