Ford Patent Wants To Save Internal Combustion

There’s no doubt the venerable internal combustion engine is under fire. A recent patent filing from Ford claims it can dramatically reduce emissions and, if true, the technology might give classic engines a few more years of service life, according to [CarBuzz].

The patent in question centers on improving the evaporative emission system’s performance. The usual evaporative emission system stores fuel fumes in a carbon-filled canister. The canister absorbs fuel vapor when under high pressure. When the engine idles and pressure in the cylinder drops, the canister releases fumes, which are combusted with ordinary fuel/air mixture.

Dad Builds Frickin’ Tank For His Son

We gotta love hacker Dads and Moms for being so awesome. Sooner or later, their kids get to play with some amazing toy that every other kid on the block is jealous of. [Meanwhile in the Garage aka MWiG] is one of those super hacker Dads who built a frickin’ Tank for his son (video, embedded below.). But it’s so much fun driving that beast around that we suspect Dad is going to be piloting it a lot more than the kid. The tank features metal tracks, differential steering, a rotating turret, periscopes and a functional paintball gun with camera targeting.

Building a tank, even if it’s a mini replica, needs an engine with a decent amount of torque. [MWiG] first tried reviving an old ATV engine, but it did nothing more than sputter and die. It went to the scrap heap after donating its rear transmission and axle. [MWiG] managed to get an old Piaggio scooter with a 250cc / 22 hp engine. The scooter gave up its engine, electricals and the instrument cluster before being scrapped. Looking at the final build, and the amount of metal used, we are left wondering how the puny 22 hp engine manages to drive the tank. We guess it’s the right amount of gearing for the win.

Hackaday Links: August 14, 2022

What’s this? News about robot dogs comes out, and there’s no video of the bots busting a move on the dance floor? Nope — it looks like quadruped robots are finally going to work for real as “ground drones” are being deployed to patrol Cape Canaveral. Rather than the familiar and friendly Boston Dynamics “Big Dog” robot, the US Space Force went with Ghost Robotics Vision 60 Q-UGVs, or “quadruped unmanned ground vehicles.” The bots share the same basic layout as Big Dog but have a decidedly more robust appearance, and are somehow more sinister. The dogs are IP67-rated for all-weather use, and will be deployed for “damage assessments and patrols,” whatever that means. Although since this is the same dog that has had a gun mounted to it, we’d be careful not to stray too far from the tours at Kennedy Space Center.

Hack Your Engine Virtually

It is no secret that we like simulating circuits before we build something and there are plenty of great tools for that. But what about those of us who work on cars? Well, you might try engine-sim which is a real-time internal combustion engine simulation. Honestly, the program freely admits that it isn’t accurate enough to do engineering or engine tuning. But on the plus side, it has audio output and is at least good as an educational tool to show an engine running and how different parameters might affect it. You can see a video of the tool below.

[Ange-Yaghi] mentions that the code was primarily to power the YoutTube demo. However, the Readme hints that it might be better — or at least different — and collaboration to make it better is welcome.

Ride-on Tracked Vehicle Is A Stout Metal Build

When we think of tracked vehicles, we normally think of tanks, or perhaps heavy construction machinery. Meanwhile the average member of the public is left out of the fun. [Bob] of [Making Stuff] won’t be one of them, however, having put together a ride-on tracked vehicle for his own enjoyment.

The machine is welded together from plenty of steel, making it more than tough enough to soak up the punishment of off-road duty. The design features four suspended buggy wheels on either side running inside rubber tracks, with a cogged drive wheel at the front. Propulsion is thanks to a 440 cc DuroMax engine good for a full 18 horsepower and 26 ft-lbs of torque, driving the tracks through a differential mounted up front.

The design has one major issue at the moment. The heavy engine is mounted ahead of the front wheel inside the tracks, which means the vehicle wants to nosedive at the slightest provocation. Such an event would be highly uncomfortable for the rider, so mods are needed, either by scooching the engine back a little or pushing the wheels forward.

We look forward to seeing [Bob] fix the issues and get the machine driving soon. We’ve seen other tracked builds before, too – often on the smaller scale. Video after the break.

Norway Leads The Charge To Phase Out Internal Combustion; China And The UK To Follow

Climate change promises to cause untold damage across the world if greenhouse gas emissions continue at current levels for much longer. Despite the wealth of evidence indicating impending doom, governments have done what humans do best, and procrastinated on solving the issue.

However, legislatures around the world are beginning to snap into action. With transportation being a major contributor to greenhouse gas emissions — 16% of the global total in 2016 — measures are being taken to reduce this figure. With electric cars now a viable reality, many governments are planning to ban the sale of internal combustion vehicles in the coming decades.

Mazda Investing Big In Advanced Gasoline Tech With Skyactiv-X

Electric cars, as a concept, were once not dissimilar from the flying car. Promised to be a big thing in the future, but hopelessly impractical in the here and now. However, in the last ten years, they’ve become a very real thing, with market share growing year on year as new models bring greater range and faster charging times.

With their lower emissions output and ever-improving performance, one could be forgiven for thinking that traditional combustion engines are all but dead. Mazda would beg to differ – investing heavily in new technology to take the gasoline engine into the next decade and beyond.
