Dyno Testing

I went to Dynojet with my senior design group and did some dyno testing on the Benz. The best run was 98 HP at the rear wheels on straight diesel. Biodiesel averaged about 5hp less. We tested B99 (99% biodiesel), B50, straight diesel, and the stuff that was in my tank which is about B70 with an anti-gel additive. It was pretty fun reving the car almost to red line at 80 up on the dyno repeatedly. These data will be compared later with what the vegetable oil system can produce. The graph below shows the power curve of the engine in 3rd gear, where it hits 5,000 RPM around 80 and power drops off significantly. I stopped reving after it was dropping off, hence the steep slope at the end of the curve. Fortunately my engine didn't blow up.
