How Old Tires Are Retreaded So They Can Be Used Again

The disposal of tires represent a significant burden on the environment. Tires can’t go to landfills; they take up too much space and are not biodegradable. Companies like Marangoni, therefore, developed methods to recycle and reuse old tires. Watch how retreading machines make old tires usable again.

How Moving Dummies Help Test Car Safety Systems

AB Dynamics employs many tools to test advanced driver assistance systems (ADAS) according to rigorous standards by automotive safety agencies like Euro NCAP and NHTSA. One such tool is the Soft Pedestrian Target, or SPT, that simulates a pedestrian in a real-world environment.

Following is a transcript of the video:

Narrator: These biking, strolling, rolling dummies take the hits so you don’t have to. They exist to make sure the pedestrian avoidance systems in today’s modern cars work. That is, when a kid runs out into the street from behind a car or a cyclist pedals into a blind spot unseen, the car takes notice and intervenes, braking or evading suddenly, likely saving the life of the pedestrian you failed to notice. You can trust your car will do the right thing when the moment comes because, before you took the wheel, it may have already avoided hundreds of kids and dozens of cyclists – those human-like dummies clad in blue pants indifferent to the cars barrelling in their direction.

How dummy pedestrians help test car safety systems.

Narrator: Advanced driver assistance systems. ADAS. They’re the technology that enables your car to brake, change lanes, or swerve around obstacles for you in emergency situations, and they’re made by different companies and operate to different results. That’s why organizations like the European New Car Assessment Programme and the National Highway Traffic Safety Administration in the United States impose rules that all manufacturers have to stick to on their ADAS tests. The rules demand a very specific speed, impact location, and lighting condition among other specifications. That’s where the Soft Pedestrian Target, or SPT, comes in. The pedestrian target sits on a robust pad or platform. The pad carries a control system that, among other things, synchronizes the pedestrian with the test vehicle, meaning that, in 100 tests, the pedestrian would arrive at the same place in front of the car at the right time at the right speed at the right angle, every single time. When the vehicle is at the correct distance from the impact point, the Soft Pedestrian Target system initiates the movement of the platform. The pedestrian target enables manufacturers to reliably comply with highly specific testing protocols repeatedly. 

This is James Buck. He’s a senior project engineer at AB Dynamics. He walked us through a test scenario using the SPT system.

James Buck: The test being shown here is as described in the 2018 Euro NCAP Vulnerable Road User test protocol whereby the subject vehicle is driving and a child suddenly runs out from behind two parked cars. This test determines whether the vehicle’s ADAS system reacts quickly enough to avoid hitting the child.

Narrator: For this scenario, the Soft Pedestrian Target is set to run perpendicular to the subject vehicle.

Buck: Since the Euro NCAP protocol requires the subject vehicle to be driven in a very specific manner, you need a driving robot to ensure that the path following and the speed of the vehicle remains in tolerance. The driver in the subject vehicle has now activated the robots, and the vehicle is following the specified path and speed profile. When the vehicle is at the correct distance from the impact point, the Soft Pedestrian Target system initiates the movement of the platform. This automatic triggering guarantees that the impact point is as described in the protocol, that is unless the vehicle breaks automatically to avoid the dummy. In this example, we have disabled the ADAS systems in the vehicle such that the vehicle will strike the target.

Narrator: The contribution these dummies make to keeping our pedestrians safe is clear.

How This Artist Engraves Entire Cars By Hand

Artist Hank Robinson does custom engravings on cars. He got the idea to use a car as a canvas when Ford came out with an all aluminum F-150 in 2016. Since then he’s engraved two entire cars including the rims, suspension system, and other parts. 

For more from Hanro Studios:

Following is a transcript of the video:

Narrator: These intricate engravings are created by Hank Robinson. He’s the owner and operator of Hanro Studios, which focuses on creating one-of-a-kind engravings for its clients. Hank is one of very few engravers who works on cars. He’ll engrave anything from wheels and bumpers to tailgates and fuel tanks. 

Hank Robinson: So, I started engraving in 2011 doing a lot of different aftermarket parts, wheels, intakes, anything to do with the automotive world. And in 2015, Ford came out with the all-aluminum body F-150, And in 2015, Ford came out with the all-aluminum body F-150, and I just knew that was going to be the endgame for me. I just knew I had to do a huge rolling canvas.

Narrator: But Hank did more than just engrave a car. He purchased a Ford F-250 and made a masterpiece called “Aluminati.”

Hank Robinson: I wanted the most badass truck with a mobile engraving station so I could roll up and just live engrave anywhere that I go. So, I really wanted to display and showcase all the different types and styles of engravings that you can do on a vehicle, as well as the different aftermarket parts. So, we have engraving on the body, the bumpers, the wheels, the reservoirs, the entire suspension, and a couple interior components. So, I’m able to use that now as a rolling business card. I attend a lot of shows and do live demos, and it’s really just a great conversation piece. My first large-scale engraving was a 2016 F-150 named “Freedom Blues.” Freedom Blues is a tribute to those who served with those who sacrificed. Being a veteran myself, I wanted to pay homage to my era of warfighters. So, with just under 900 total engraving hours, I was able to depict our experiences at wartime, and it was an awesome experience. I got to finish live engraving at SEMA 2016, which was the first time I got to showcase my engravings on a large platform in front of large audiences.

Narrator: Hank’s attention to detail is what sets his work apart from the rest. It’s even allowed him to work with celebrity clients. So, I have a wide variety of clientele. 

Hank Robinson: Anybody from my neighbor to different veteran organizations, charitable organizations, companies big and small. I’ve also been fortunate enough to work with athletes and musicians such as the Dirty Heads. I did a couple pieces for Five Finger Death Punch, Tech N9ne. I’ve been featured on West Coast Customs doing some really cool engraving on Kid Rock’s Cadillac. My process varies for each project. First, I work one-on-one with the client to kind of get the ideas and get a feel for who they are. Once I have all the information, I’ll sketch out a design. Once the design’s finalized, I will use a carbon pen stencil and get my base outlines and just make sure everything’s to scale and in proportion. Once that’s done, it’s time to engrave. I really try to strive and provide engraving for anybody in any aspect of life. I don’t really want it to be just automotive or just one single solid category. I want to do absolutely everything.

How To Increase Your Car’s Horsepower

Extrude honing is a process that uses putty to increase a machine’s functionality. We take look at how it helps the automotive industry.

#Horsepower #Cars #BusinessInsider

Following is a transcript of the video:

Narrator: I know what you’re thinking. No, this is not one of those viral slime videos. You’re looking at a process called extrude honing. But what exactly is it? 

Gary Kubo: Extrude honing is a hydraulically forced abrasive flow machining process.

Narrator: That’s Gary Kubo. He’s a research and development specialist for a company called Extrude Hone AFM. And to put his definition in simple terms; extrude honing forces abrasive material through metal passages via hydraulic pressure. Depending on the item, this could have a multitude of benefits. But for now, let’s focus on how it can make your car faster. This is how putty can increase your horsepower. To really understand the benefits for your car, you’ll need to understand the importance of airflow to an engine. So we spoke with Edward Hwang. He’s been an automotive technician for over 15 years.

Edward Hwang: You need three basic things in order to have an ignition event. So that’s gonna be air, fuel, and spark or something to create an ignition. Air from the atmosphere enters into the engine bay through some sort of ducting, initially hitting the intake air filter through intake tubing, past the throttle body, into the intake manifold where the air is evenly distributed into each individual cylinder, into the combustion chamber past the intake valves. If we increase the airflow to an engine, the engine’s computer system will then match that amount of air with the proper amount of fuel. If we increase fuel, we can increase power. 

Narrator: And we all know what happens with more power. So how does this putty increase airflow? Well, the answer is literally in the putty. 

Gary: The putty is made out of a proprietary silicone polymer and it contains specialized silicone carbide particles and as the process of flowing goes through a part it [has a] honing effect. 

Narrator: So, a silicone polymer, the putty, carries an abrasive material, the silicon carbide particles. Let’s make this simple and see how the process works on an intake manifold. The intake manifold is responsible for evenly distributing the air into each cylinder of an engine. As the particles are pushed through the intake manifold via hydraulic pressure, they begin sanding or grinding away at buildup and smoothing imperfections. This is what increases airflow and turns your car into a certified speed demon. But, not every time.

Gary: Well, the results will vary depending on the part. If you’re starting from scratch, say like a rough unshaped ported head, I mean the results – the improvements could be drastic. 

Narrator: But, depending on how much power you’re adding to your vehicle increasing the airflow may not be enough. 

Edward: So when we talk about airflow, we have to talk about balance. The exhaust has to be considered as well. The engine in its basic form is an air pump. So if we have an increased volume of air coming in we have to be able to reject the spent gases out. So if we have a very large intake but a smaller exhaust diameter, for instance, it can actually choke the engine. 

Narrator: So, if you noticed your car losing power over time you may not need that new, fancy turbo to reclaim your precious speed. You may just need to clean out some key parts that help airflow to the engine.
