Senior project engineer at MTU Detroit Diesel. "According to Michael Parks, the new design reflects a number of advances in diesel technology over the past 35 years. "

“Things like going from a mechanically controlled simple injected [fuel] spray to a high pressure common rail is, by far, the best improvement to diesel engines,” he explained. “We had some fuel injected systems back then, but nothing along the lines of common rail, where it’s extremely high pressure fuel being atomized in the cylinder rather than sprayed. With that, now you get extremely good control cylinder to cylinder, as well as the entire engine, for power, peak pressure, combustion, heat out the exhaust, and timing. You’ve got a lot more control of the engine.”
