How many miles do you have this year?

If you want a reliable, high HP trail sled that gets decent mileage, four stroke is the only way to go.

Just the young guys on mountain sleds with cans want a two Stokes or the guys going from bar to bar.

Big milers don't give 2 fucks about 30 or 40 pounds.

Maybe the big milers who are on the frozen highways in Quebec.  Around here, wrestling that 40 extra pounds on the front of the sled all day is going to make a big difference.  

Got to see one of these up close at the the Air Force Museum just outside Elgin Air Force Base in Florida.  Coolest thing they had there.  LA to New York in just over an hour.

Cummins Newsroom:

CAN AN ENGINE RUN ON HYDROGEN?

Jun 09, 2023 by Jim Nebergall, General Manager of the Hydrogen Engine Business

Your hydrogen questions answered

 

Companies working to achieve their decarbonization goals are increasingly interested in hydrogen engines. Over the past year, leading companies like Tata Motors, Buhler Industries and Werner Enterprises have expressed interest in Cummins 15-liter hydrogen engine. More leading companies can take advantage of hydrogen-powered solutions to decarbonize as these technologies become more cost-friendly and widely available.

IS THERE AN ENGINE THAT RUNS ON HYDROGEN?

Yes. Hydrogen internal combustion engines (hydrogen ICE) work similarly to diesel engines. Hydrogen is burned in the same way a traditional internal combustion engine burns gasoline or diesel. Hydrogen engines have near zero emissions, and they don’t emit soot or volatile organic compounds. In fact, hydrogen engines can deliver over 99% reduction in carbon emissions compared to diesel. It’s considered a zero-carbon technology.

Cummins is leading the way in the transportation industry with its hydrogen internal combustion engines. These engines are being developed with current vehicle designs in mind and aim to make the transition to hydrogen simple for OEMs and their customers. Cummins’ fuel-agnostic platform includes both a 15-liter and 6.7-liter hydrogen engine.  This offers the benefits of a common-base architecture and low-to-zero carbon fuel capability. So, will we ever see a hydrogen truck anytime soon?

The 15-liter hydrogen internal combustion engine is expected to reach full production in 2027. To date, Cummins has debuted two hydrogen ICE concept trucks. One was a heavy-duty concept truck featuring the X15H, and the other was a medium-duty concept truck powered by the B6.7H. Both concepts truck replicates a feasible vehicle production and demonstrates an easy integration fit with no impact on payload or space requirements. The heavy-duty truck is expected to have an operating range of more than 500 miles and reach 500 HP. It has a 700 bar pressure 80kg high-capacity hydrogen storage system. 

This medium-duty engine is expected to reach around 290 HP and 1200Nm peak torque. Cummins is aiming for similar performance characteristics of a diesel engine that are compatible with existing transmissions, drivelines and cooling packages.

DO HYDROGEN ENGINES NEED SPARK PLUGS?

Yes. Hydrogen ICE needs spark plugs. The hydrogen combustion process is similar to engines that use natural gas, or gasoline. Hydrogen is stored in high-pressure tanks and is fed into the engine's combustion chamber where it is mixed with air. A spark plug ignites the mix, which rapidly combusts. The pressure created in the combustion chamber moves the pistons, which drives the crankshaft, causing a rotating motion. Because of the need for spark plugs, it is crucial to follow the recommended maintenance intervals, which may differ from those of diesel vehicles. 

CAN DIESEL ENGINES RUN ON HYDROGEN?

No. While vehicles with diesel ICEs share a lot in common with hydrogen ICEs, a diesel ICE cannot run on hydrogen alone. Diesel ICEs operate on a compression-ignition cycle, and thus, feature no spark plugs. Whereas, hydrogen ICEs operate on a spark-ignition, and as such, require spark plugs to ignite fuel. 

Additionally, H2-ICEs incorporate a number of features that are required for safe and efficient operation. This includes high-pressure storage tanks which undergo rigorous industry standard testing and certification. Cummins and NPROXX announced a joint venture to deliver industry-leading hydrogen storage options. The two engines also have very different exhaust aftertreatment systems. A diesel ICE exhaust system is designed to reduce NOx and particulate matter emissions. In contrast, a hydrogen ICE exhaust system is simpler because of the lower NOx and virtually no particulate matter emissions. 

WHAT ARE THE SIMILARITIES BETWEEN DIESEL AND HYDROGEN ENGINES?

Diesel and hydrogen engines do have similarities, though. To take full advantage of the similarity between these engines and to create optimal solutions for its customers, Cummins is developing fuel-agnostic engine platforms. These platforms consist of a base engine architecture around which a set of engines optimized for different fuels can be built. Each engine will then operate using a single fuel. This approach makes it easier for OEMs to offer versions of the same vehicle operating on different fuels. 

End-users operating mixed-fuel fleets also benefit from using engines derived from the same platform. The high degree of parts commonality, for example, makes it easier to manage parts inventory and communize on maintenance practices. 

Customer interest in hydrogen engines is growing. Companies and fleets that use Cummins’ fuel-agnostic engine technology will be well-positioned to transition to a hydrogen-powered fleet as hydrogen fuel becomes a more widely available. Though hydrogen vehicles will use different fueling systems and onboard storage for hydrogen, mechanics and drivers will already have some familiarity with the engines. This journey to adopting hydrogen-fueled vehicles is much more economical than starting from scratch. 

Cummins stands ready to partner with customers interested in transitioning to hydrogen-powered vehicles and helping them decarbonize and achieve their environmental goals.

Hydrogen combustion engines have been all the rage at the shows and in trade publications the last few years.  There was never really a technology gap there.  The issue has always been sourcing the hydrogen in the H2 gas form.

Can’t wait for the first hydrogen powered sled.

If we do the exhaust right. it could blow out enough water to cover the trail behind you in fresh snow for the next guy.

Sioux Falls race this weekend.  Supposed to be sunny and 65F on both Friday and Saturday.  

Elias isn't in the top 5 any more but they should still let him take the parade lap during opening ceremonies.

Gotcha. Figured it would go to more wins 

Nope, what position you finish is the number of points you get.  Overall winner is the lowest total points.  Tie decided on the lowest points awarded in the last round.

What's nice about the triple crown is you can't finish back of the pack in the heats and then rip one hole shot and win the final.

Cherish this one Cat faithful.

hope @krom gets time to post later... but I guarantee that head fukstyk in tech is going to tear every last inch of those sleds apart, so Krommy probably won't get out of there until the Capri Sun is gone at four in the morning.  

It's been awhile since Alex has torn the top end off a Cat that wasn't his own.  Think he remembers how?  Hopefully Krom is there to lend a hand.

Yurk with the overall with the same points but 1 win vs 2?

Yurk was behind 2 points and won by 2 points in the last round.  Tie goes to the rider placed higher in round 3.

Wait until next year when all those people ignore the recall and didn't ride this year so they have two year old fuel.

I took my now wife to a Red Sox game years ago she had never been. The entire time she’s bored looking around so I’m telling her pay attention like not even 15mins later a line drive foul nails someone right in the face not paying attention couple rows In front of us blood everywhere. I look over and go that’s why you pay attention lol she was terrified the rest of the game lol. Baseball is boring as shit though I can only stand it at the stadium in person.

Last spring I took my team at work out to a Twins game for one of the guys retirements.  Nice spring day with good seats and company paid beers, only way to watch a baseball game!  This beat the cake and coffee reception most do.

Sure are, but it’s super convenient because they still use the plastic secondary rollers. So you have to have all the special tools or drop your sled off to a shop within your first 3 rides when they explode so you can put the fiber ones in.

Might as well just buy the tools because you can't get to the helix or spring without them.  

I like being able to service the primary without needing a special holder and tool to break free the spyder to change the rollers.  On my Cat it was more practical to just buy a new clutch.

@f7ben you will like this one.  Guy is handcuffed in the back of a squad car, acorn falls on the car from a tree.  Cop thinks he is getting shot at and does a few barrel rolls on the ground before emptying a mag on an unarmed, cuffed suspect in the back of his car.  Also claims "I've been hit" even though the suspect didn't even have a gun, much less shoot one.  Both cops missed every single shot and the guy in the back of the squad was unhurt.  

OKALOOSA COUNTY, Fla. (WKRG) — Marquis Jackson recently shared, publicly, the story of what might have been the scariest day of his life.

Man suffers life-threatening injuries after shooting Sunday night: Mobile Police
The search for a vehicle
It all began at 8:42 a.m. on Nov. 12, 2023, on McLaren Circle, when the Okaloosa County Sheriff’s Office received a call of a vehicle driving around honking its horn, disrupting the peace since 3 a.m.

A woman then called the sheriff’s office, accusing Jackson, 22, of taking a vehicle and sending threats via text message and phone calls.

According to the sheriff’s office, Jackson arrived at the scene around 9:09 a.m.; he was detained, searched, handcuffed and placed in the rear of Deputy Jesse Hernandez’s patrol vehicle.

The woman then completed an affidavit for a stolen vehicle. She told deputies Jackson had a silencer, but she wasn’t sure where it was, and that he had more than one weapon.

INCIDENT LOCATION:

2 men arrested in counterfeit currency scheme at Foley Tanger Outlets: Police
‘Shots fired! Shots fired! Shots fired!’
When Hernandez was returning with a Victim’s Rights form for the woman, other deputies had communicated they found her vehicle, according to the news release.

Hernandez then approached the passenger side rear door of his patrol vehicle to do a secondary search of Jackson when he heard a pop sound, which he thought was a gunshot, and believed he had been hit, according to an OCSO news release.

Hernandez yelled “shots fired” multiple times, fell to the ground, rolled and began firing in the patrol car, according to body camera footage of the incident.

Sgt. Beth Roberts then began firing into the vehicle in response to the perceived threat after she saw Hernandez’s response, reaction, and fear for his life.

Jackson escaped injury, and no weapon was located, the OCSO said.

Witnesses said they heard what they thought could have been a muffled gunshot, according to an OCSO news release. Three News 5 reporters listened to the body camera footage and did not hear the sound described.

Hernandez, who had been with OCSO since January 2022, resigned on Dec. 4, 2023, according to the OCSO. Roberts has been with OCSO since May 2008.

Both were current on resistance training and firearms qualifications, according to the sheriff’s office.

The internal investigation
The Okaloosa County Sheriff’s Office Professional Standards conducted an internal investigation and determined Hernandez’s use of force was not objectively reasonable, according to an OCSO news release.

Hernandez violated policy regarding excessive use of control to resistance, the release said.

The investigation determined that Roberts’ use of deadly force was objectively reasonable, and she was exonerated, according to OCSO.

The OCSO Criminal Investigations Division reviewed the incident after initial investigation for any possible criminal charges.

The sheriff’s office also reportedly requested an independent review by the 1st Judicial Circuit State Attorney’s Office. Ultimately, no probable cause for criminal charges was found.

WKRG News 5 requested the body camera footage from this incident on Feb. 7; the OCSO released the footage (seen above) today.

‘All I could depend on was God’
In a public Facebook post, Jackson recalled the day he could have died.

Specifically, he wrote, being handcuffed and placed in the backseat of Hernandez’s vehicle, and what shortly followed.

“A few moments later I hear an officer scream ‘I’m hit, he’s armed’!” Jackson said in the post. “As soon as that was announced multiple shots were fired at me while I was stuck in the backseat. All I could do was lean over and play dead to prevent getting shot in the head.”

Jackson said he was “scared to death and I knew all I could depend on was God! I ignored everything and prayed! Windows were shattering on me the whole time as bullets continued flying across me.”

He said he was blessed not to get hit by bullets or physically be hurt, “but mentally, I’m not ok. I haven’t been the same since and I don’t think this feeling I have will ever change.” 

“I truly believe I’m damaged for life!”

Man arrested in Okaloosa County for DUI, multiple drugs found in car: FHP report
‘We are very thankful Mr. Jackson wasn’t injured’
Okaloosa County Sheriff Eric Aden released a statement regarding the incident and Hernandez’s resignation. He also posted a video to the Okaloosa County Sheriff’s Office YouTube page.

In that statement, Aden said the OCSO must work to protect both officers and anyone accused of a crime.

“We are very thankful Mr. Jackson wasn’t injured and we have no reason to think former Deputy Hernandez acted with any malice,” Aden said. “We are limited in further response due to pending litigation. But let this be clear, we understand this situation was traumatic for Mr. Jackson and all involved and have incorporated this officer involved shooting into our training to try to ensure nothing similar happens again.

“Though his actions were ultimately not warranted, we do believe he felt his life was in immediate peril and his response was based off the totality of circumstances surrounding this fear.

“Just as we have an obligation to protect our officers so they can go home safely to their families, law enforcement has the same obligation to any citizen being investigated for a crime.”

How you been, TG?  

Been good, traveling a lot lately while I wait for snow.  Bought a Sportsman 850 last fall, Todd bought a 1000, so got out on those a few times last fall.  Complete lunacy after coming off 400-500 cc singles to big bore twins.  Watched snox from the beach in Florida.  Maybe head up there for the Duluth races?  Should be shorts, t-shirt, and croc weather.

Went to the boat show in January.  People are still buying but inventory is stacking up.  Prices are nuts but they say inflation is transitory so don't worry.

No barbie hands here either.  Now I have all sorts of "special tools".  At least your sled doesn't have the second clutch fixed to the jack shaft...

Some day I'll tell you all about my 3 hour experience replacing spark plugs.

Catalyst mods were being built in TRF at the race department from what I heard.  Herf said that in one of his videos where he was out testing and his mechanics were up in TRF building mod sleds.

Benham has been helping develop the new SX sled.  Wonder if they will use the new 600 platform with the 800 bottom end?

4th I believe, Yurk was 5th.

The hotel next to my work has been full of immigrants for the last year.  It still has the hotel sign on it but you can't book a room there.

Many other hotels along 494 in Bloomington are doing the same thing.

from the angle I saw it was a wicked bonehead cross jump move.

There is no way Elias tried to cross over there.  At those speeds, the moguls kick the sleds left and right with no warning.  He came up short on the previous jump and got squirrely which is really what started the whole series of events.
