Interesting Arctic Cat patents

Kinda surprised these pics haven't circulated more...

OIl pump mounted to the front of the engine, driven from the water pump shaft.  Oil used to lube an automotive high pressure fuel pump that is shown belt driven above the mag housing, with fuel rail, and injectors on cylinder head:

Turbocharger fed with oil from pump, water cooled turbo, and air to water intercooler:

42 is the oil tank, 142 is the water to air intercooler, 146 is the intake manifold

I keep going back to look at that patent and the PPE patent and looking at their catalyst to see if it is possible to shove their parallel path turbo system in there (particularly the one with the turbo right off the Tri-pipe). would love to see a video of one of their turbos in testing even if its on a bench to see why its beneficial to seperate the turbo from the pipe.

Closer to the exhaust port the turbo is, the more efficient, and quicker responding it is

Pretty neat.  I wonder if they'll have a different variation of the catalyst to accommodate the size.  I didn't read the patent (supercross is on), what is the patent actually for?

interesting way to do direct injection... on a sled.  

#2 looks like a @Tommcat special

Polaris had the oil pump and water pump driven off of the crank , on opposite sides mind you, back on the 2000 xc600sp so that's not exciting at all. But the injectors on the head is very interesting.

The injection oil pump is still electronic, and mounted in/near the tank
That belt driven pump isn't for oil, or water, it is for high pressure gasoline direct injection.
The oil pump for it, and the turbo is mounted where AC has always used to mount the 2 stroke oil pump, with a small tank mounted to it, as the oil is recirculated

If the bottom is built like a tank that thing should make big power. The limiting factor on the turbo kitted sleds are the fuel systems and bottom ends. Going to that injection system with a beefed up bottom end will make a turbo trail sled Wicked

I think Ski-doo has the better turbo idea by dropping the intercooler. You can grab a $3 jug of super tech windshield washer fluid top keep the injection tank topped off and pour yourself a blue shot or two at the same time.

There are a bunch of variations of for different rear skids in that patent.  Most of them are designed to make the spring progressive (spring rate increases though out travel, instead of remaining linear like a normal steel spring)

#72 is a way to adjust the crossover point (where in the travel the spring increases its rate)

Could that be an Alpha rail…. Theoretically?

that was a few years back if I remember correctly
