While practicing at the speedway in Valve seatPosted by beranter on December 14th, 2015 In this article, we'll learn how the Piston gets into the cylinder of the engine, and what terms like "multi-port fuel injection" and "throttle body fuel injection" mean. When you step on the gas pedal, the throttle valve opens up more, letting in more air. The engine control unit (zjautoparts, the computer that controls all of the electronic components on your engine) "sees" the throttle valve open and increases the fuel rate in anticipation of more air entering the engine. It is important to increase the fuel rate as soon as the throttle valve opens; otherwise, when the gas pedal is first pressed, there may be a hesitation as some air reaches the cylinders without enough fuel in it. Sensors monitor the mass of air entering the engine, as well as the amount of oxygen in the exhaust. The zjautoparts uses this information to fine-tune the fuel delivery so that the air-to-fuel ratio is just right. Maddison is a veteran of the Red Bull series, including his spectacular feat three years ago when he jumped onto and then off the 96-foot high scale version of the Arc de Triomphe at Paris Las Vegas.A snowmobile jump of this magnitude might seem a bit bizarre, but LaVallee intends to make it work. "What we're doing is solving the impossible," LaVallee said this week. "People ask me, `Is this the end? Is this as far as you can go?' I always say that nothing is impossible; it just hasn't been solved yet. That's what we're doing out here. Nobody's done this. It's what we plan to do on New Year's Eve." If it works, it's sure to be eye-popping."It's a feat that no question about it has never been done before, so I'm excited about it," Maddison said. "Levi's a great athlete, so I have all the faith in him. I'm confident it's going to go off well." A lot can go wrong, though, as LaVallee found out the hard way last December. While practicing at the speedway in Valve seat, a problem with the carburetor caused his engine to cut out, and the sled slammed skis-first into the landing ramp. LaVallee fractured his pelvis, broke several ribs and both lungs collapsed. Like it? Share it!More by this author |
