Exhaust Particulate Emissions of a Mustard Seed Oil Driven Tractor Engine 2002-01-0866

Exhaust emissions of particulate matter (PM) of a direct injection turbocharged, intercooled tractor diesel engine were determined, while fueling the engine with a vegetable oil pressed from mustard seeds.
The un-esterized mustard seed oil (MSO) was cleaned by simply letting it stand and clear. Appropriate injector tips were first selected. Thereafter, performance and exhaust emissions were measured in the large load-speed envelope. The results were compared to those obtained while running the engine with diesel fuel oil (DFO).
The results showed that the engine emits more fine and ultra-fine particles when running with MSO than with DFO, although the exhaust smoke and total hydrocarbon emissions were lower and the brake thermal efficiency was very similar. In the range of larger particles, PM emissions were lower with MSO at high loads and lower with DFO at low loads.
Preheating of MSO reduced the PM emissions, but not to a level observed with DFO in the range of nanoparticles. A raised temperature of the primary diluter did not affect the PM result characteristics with MSO.
Further optimization of the entire injection system for MSO was thought to be one of the main subjects for the subsequent phases of the research program. Additionally, a chemical analysis of particle samples is required to provide information about the composition of each particle fraction. Testing of catalytic converters is also of interest.
