General Motors is investing $888 million in its Tonawanda Propulsion plant in Buffalo, New York, "to support the production of the sixth generation of GM’s V-8 engines," the automaker announced Tuesday. The investment is a shift from a previously announced $300 million commitment to make electric-vehicle drive units at the plant, as the V-8 engines are used in GM's full-sized trucks and SUVs. GM says the newer engines will provide drivers better fuel economy and reduce emissions by utilizing "new combustion and thermal management innovations." "Our significant investments in GM’s Tonawanda Propulsion plant show our commitment to strengthening American manufacturing...

The owner had just left the dealer's yard when the engine of the brand-new Cadillac Escalade failed, and they had to call a tow truck to take it back.

General Motors is now the subject of an NHTSA investigation after more than a thousand complaints were logged over sudden and catastrophic failure of some of its “L87” 6.2-liter V8s—a core power plant for Cadillac, Chevy, and GMC trucks. It’s actually the latest in a string of uncommon but linked reliability problems to impact the 5.3- and 6.2-liter small block families over several recent model years—a notably bad run for what’s supposed to be an uncomplicated, naturally-aspirated V8 engine.

The electric motor might carry the hype banner at the moment, but some minds remain convinced that there's plenty of innovation left to be extracted from internal combustion. AIE is one of the rotary engine's biggest champions and has been advancing new rotaries via the latest manufacturing tools and techniques since 2012. Its latest release shows that Wankel engines can be a perfect fit for compact, power-demanding applications in robotics and aerospace. More palmable than a basketball, the 40ACS Wankel packs a power-to-weight punch in a package that disappears away in small spaces. The last time we looked in on...

I was trying to get a list of all the most recent trans-shooters but everything that comes up is "trans that are killed by XXX" or "mass shootings committed by white men". I have used Brave search, Duck Duck go and and they give almost the same crap results as Google. Are there any others? It's so frustrating that no matter what I search it's always the left's slant on it...

An innovative new combustion engine eliminates half the guts of a traditional engine, and uses a fascinating internally-rotating piston and sleeve arrangement, making it lighter, simpler and more efficient while still making strong power and torque. Michael Arsenaeu designed the Avadi engine 20 years ago in the hopes of creating an entirely new engine design to be efficient as well as reduce emissions. In 2015, Avadi began the build and development. Rotary might be a good name for this sort of engine, if the name wasn't already taken. Everything inside the crankcase rotates, but unlike a Wankel-style rotary engine, this...

In 2084, humanity had finally turned its back on burning the ancient remains of a bygone era, only to find itself shackled to the caprices of the sun and wind.In the year 2084, the world had reached an equilibrium of sorts — a strange, unbalanced balance that no one had aimed for but had settled into, like dust after a storm. The skies, once bustling with the egalitarian hustle of air travel, had quieted down, reserved now for the sleek, whispering jets of the elites: politicians who crafted the future from the clouds; entertainment superstars like Brittany Quick, whose laughter...

PALMDALE, Calif. — House appropriators don’t intend for the Pentagon to re-engine the F-35 with a new adaptive powerplant, the chairman of the House defense appropriations subcommittee (HAC-D) said this week. “It states pretty specifically in the appropriation bill that we’re not looking or seeking to change out the Pratt & Whitney engine,” Rep. Ken Calvert, a California Republican, said in a Wednesday interview with Breaking Defense at the inaugural North LA Defense Forum hosted by Rep. Mike Garcia at Northrop Grumman’s facilities here in Palmdale. “Unless there’s a catastrophic failure on the part of [current engine maker] Pratt &...

A Texas airport worker was killed after being sucked into a jet engine at San Antonio International Airport on Friday night, according to a report. Emergency crews were called to the tarmac just before 10:30 p.m. after reports that a ground worker had been “ingested” into the engine of a plane that had just landed. “Delta Flight 1111 was taxying to the gate, with one engine on at that time, and a worker was ingested into that engine at 10:25 p.m,” the NTSB said in a statement to KENS5. An investigation into the worker’s death is ongoing. “The NTSB has...

Eleven more U.S. airports plan to adopt a new way of landing planes that reduces both emissions and noise — all by having incoming planes turn off their engines and glide down to the tarmac like a paraglider. The Federal Aviation Administration announced Monday that planes heading to Orlando, Fla.; Kansas City, Mo.; Omaha, Neb.; Nebraska's Offutt Air Force Base; Reno, Nev.; and six airports in South Florida soon would make idle descents to runways. It's a method called “Optimized Profile Descent,” and more than 60 U.S. airports already have it in place.

The winter is already brutal on your car because of the conditions, but drivers can make things harder by turning on the vehicle to let it warm up before driving. One thing some do when the temperatures are cold outside is to start the car and let the engine warm up a few seconds before driving. Several auto experts believe this may not be conducive to preserving the engine.

Former President Donald Trump was forced to make an emergency landing on Saturday after a plane he was traveling on suffered engine failure, according to reports. Politico reports, citing “two people familiar with the matter” that the incident occurred after Trump concluded his speech to donors in New Orleans and left to return to his home at Mar-a-Lago.

The compact, flat Koenigsegg Quark motor is designed to integrate easily into supercars and other vehiclesKoenigsegg VIEW 8 IMAGES Not one to let the inadequacies of existing technology stand in its way, Koenigsegg has been an innovating pioneer in modern powertrain technology, rethinking fundamentals with solutions like gearbox-free direct-drive hybrids and camshaft-free engines. Its latest breakthrough has come in the form of a compact electric motor that squeezes together the torque-heavy benefits of axial flux topology with the power-dense boost of a radial flux layout. The all-new Quark motor will help the boundary-smashing Gemera four-seat GT achieve sprint times formerly...

The Japan Aerospace Exploration Agency (JAXA) has announced that it has successfully demonstrated the operation of a “rotating detonation engine” for the first time in space. The novelty of the technologies in question is that such systems obtain a large amount of thrust by using much less fuel compared to conventional rocket engines, which is quite advantageous for space exploration. On July 27, the Japanese agency launched a pair of futuristic propulsion systems into space to carry out the first tests. They were launched from the Uchinoura Space Center aboard the S-520-31, a single-stage rocket capable of lofting a 220...

A fan blade that snapped off a United Airlines engine mid-flight, causing it to rain debris over Colorado last month, had microscopic cracks, federal investigators with the National Transportation Safety Board said Friday. The engine part was last inspected more than four years ago. The Boeing 777 made an emergency landing back at Denver International Airport on Feb. 20 after the engine caught on fire soon after takeoff. No one onboard or on the ground was injured. The broken blade on the Pratt & Whitney engine had been used on 2,979 flights since its last inspection in 2016, the NTSB...

This post was updated 5JUL19, when I received word that the FDA approved Bremelanotide PT-141 under the name Vylessi. I updated this post, and subsequently added the name Vylessi to all mention of Bremelanotide PT-141, and added updated histories and commentaries at the end. We have a tendency to think inside the box. We try to improve what we know. We try to work within the framework of what we have. We actually do need to think "outside the box"...

Back in the day, I was one of the first people to start using Google as a search engine. I liked it’s clean interface, and simplicity. Of course, over the years, other people also found this to be the preferential search engine. Unfortunately, Google became big, powerful and yes, evil. They siphon up your personal information with zero regard to fourth amendment protections. They sell the information to the highest bidder, and give it away for free if the person is part of a government agency. Unfortunately, people like myself VALUE privacy. And that means that I no longer can...

In a statement, Delta Air Lines said Flight 1425 was diverted “after receiving an indication of an issue with one of the aircraft’s engines.” An earlier statement from Delta called the failure a “possible incident” — an instant classic in corporate understatements. The company declined to say whether passengers were in danger or describe what went wrong. Media reports indicated Delta offered passengers $30 food vouchers as they waited for a flight out of Raleigh, and CNN reported the plane was back in service Wednesday after the engine was replaced. The aircraft involved is an MD-88, the oldest in service...

The Raptor engine is designed to power the spaceship currently known as Starship as part of the rocket assembly currently known as Super Heavy (previously dubbed the BFR). The first Raptor test fire took place in September 2016, when the company was targeting an uncrewed Mars launch in 2018. Three Raptor engines like this one are built in to the Starship Hopper, which has been under construction in Texas and which SpaceX will use to begin testing the rocket technology in real life. SpaceX plans to assemble 31 Raptor engines into the Super Heavy rockets, with another seven Raptors on...
