## Описание

One of the most technically advanced four-cylinder engines ever just launched. A small, two-liter inline-four is cranking out 324 horsepower, but it’s not just the power that’s impressive, as it’s thermal efficiency can rival that of a Toyota Prius engine. The secret? Turbulent Jet Ignition - the same technology used in Formula 1. A tiny pre-chamber surrounds the spark plug, which when it fires, shoots out flames from the pre-chamber, igniting the air-fuel mixture rapidly, reducing the likelihood of knock, and efficiently producing power. Compare this to traditional engines, where the flame propagation is much slower. This rapid combustion is combined with a variable geometry turbocharger, rare for gasoline engines, that supplies up to 35 PSI of boost pressure, resulting in a highly potent engine, that sips fuel politely.

One of the most technically advanced four-cylinder engines ever just launched. A small 2-liter inline-four is cranking out 324 horsepower, but it's not just the power that's impressive as its thermal efficiency can rival that of a Toyota Prius engine. The secret? Turbulent jet ignition. The same technology used in Formula 1. A tiny pre-chamber surrounds the spark plug which when it fires shoots out flames from the pre-chamber igniting the air-fuel mixture rapidly reducing the likelihood of knock and efficiently producing power. Compare this to traditional engines where the flame propagation is much slower. This rapid combustion is combined with a variable geometry turbocharger, rare for gasoline engines, that supplies up to 35 psi of boost pressure resulting in a highly potent engine that sips fuel politely. Pinkies out. The first application of this engine is the Jeep Grand Cherokee, but I can think of a few places I'd love to see it. And no, not as a bedroom poster, you freaks. Okay, it's a poster in my bedroom.
