In honor of the start of March Madness...To use a basketball analogy, you could say the Scuderi Engine demonstrates explosiveness in the lane with unprecedented consistency at the line. This week's official announcement of the engine's coefficient of variability (COV) could also be considered another landmark victory for Team Scuderi.
Testing of the naturally aspirated, one-liter gasoline engine at Southwest Research Institute in San Antonio, TX, continues to meet or exceed the initial computer simulations. The current testing program, which maps the engine from idle to 4000 rpm, measures how the engine operates under a variety of driving speeds up to full throttle - or "full load."
While a COV of 2.5 - 4 percent (the measurement indicating how much combustion varies from rotation to rotation), is right around the same levels of a conventional Otto engine and even sometimes better, but the important point here is that it happened when firing AFTER top dead center. In the Scuderi Engine, combustion starts around 12 degrees in the rotation after the piston has reached top dead center and completes the burn at approximately 23 degrees in the crankshaft's rotation. The fast flame speed reduces temperatures and lowers emissions.
One story out this week from Car Magazine UK spotlights the Scuderi Engine and how the combustion is accomplished. One of the graphics on the page nicely illustrates eight key points in the new Scuderi Cycle.
