16 FAMOUS LOGOS WITH A HIDDEN MEANING (That We Never Even Noticed)

16 FAMOUS LOGOS WITH A HIDDEN MEANING (That We Never Even Noticed)

How to design a successful logo? How to build a famous brand for your business? Some of the most well-known logos in the world were purposefully designed to indicate something much more than simple beauty. In fact, it seems that in some cases, every line, curve, and color has meaning behind it. Adidas, Apple, BMW, Coca-Cola, Toyota… We see these famous brands everywhere but never consider what their logos exactly mean. Curious to know the secret? Watch the 16 famous logos with a hidden meaning you've never noticed. Hyundai 0:33 The letter ’Н’ symbolizes two people – a client and a representative of the company – shaking hands. Adidas 0:52 The current logo is three stripes at an angle which together form a triangle. This symbolizes a mountain, which in turn represents the challenges that all sportsmen have to overcome day after day. Apple 1:21 Rob Janoff, the designer who came up with the world-famous Apple company logo, explained his idea in one of his interviews. He bought a bag of apples, placed them in a bowl, and spent time drawing them for a week, trying to break the image down into something simple. Vaio 1:58 The first two letters of the Vaio logo symbolize an analogue wave. The last two are similar to the numbers 1 and 0 — that is, symbols of a digital signal. Amazon 2:14 The orange arrow is similar to a smile because the company wants its customers to be satisfied. The arrow is also stretched between the letters ’A’ and ’Z’, in a hint that the company sells absolutely every product you can imagine. Baskin Robbins 2:40 The pink-colored parts of the "BR" section make up the number 31, which is how many ice cream flavors Baskin Robbins used to famously sell. Toyota 2:56 The logo represents a stylized image of a needle eye with a thread passing through it. This is a hint at the company’s past – they used to produce weaving machines. Continental 3:28 Continental, a famous car tire producer, has a logo in which the first two letters depict a car wheel. Formula 1 3:41 If you look carefully at the white space between the letter ’F’ and the red stripes, you can see the number 1. Pinterest 3:59 On Pinterest, people collect images they like from across the Internet and ’pin’ them to their online boards. That’s why the image of a pin is hidden in the letter P. Beats 4:17 Beats, an audio equipment producer based in the USA, uses a logo in which the letter ’B’ looks like headphones on a person’s head. Toblerone 4:32 The famous chocolate company based in Bern, Switzerland, has a silhouette of a bear in its logo. That's because Bern is sometimes called a city of bears. BMW 4:55 The logo is simply a part of the Bavarian flag, the area of Germany where the company originated. LG 5:18 The logo is a stylized image of a person’s face. According to the company, this represents its aspiration to have human relations with their customers. Evernote 5:34 The corner of the elephant’s ear is folded over in a similar way how people fold the corner of a page to make notes. Coca-Cola 5:57 In the space between the letters ’O’ and ’L’, you can see the Danish flag. It’s purely a coincidence. Nevertheless, Coca-Cola has used this as part of its marketing campaigns in the Scandinavian country. If you’ve enjoyed this video, hit that thumbs up button!

10 Reasons Why Engines Lose Power Over Time

10 Reasons Why Engines Lose Power Over Time

Why Do Engines Lose Horsepower As They Get Older? Sponsored by: https://www.AutoTempest.com/ Subscribe for new videos every Wednesday! - https://goo.gl/VZstk7 There are four things a gasoline engine requires to generate power and almost any engine problem will come down to something relating to one of these four factors. 1. Air 2. Fuel 3. Compression 4. Spark Dirty Air Filter A clogged air filter makes the engine work harder to pull in air, and can restrict the maximum amount of air let in. Less air means less power. Exhaust Restrictions The engine will have to work harder to push out exhaust gases, limiting power. Catalytic converters can clog up on engines with an improper air/fuel mixture or as a result of fuel additives reacting within. Mufflers can also fail internally, and alterations of the internal piping can result in an airflow restriction. Fuel Injectors Deposits can build up on the injectors over time from heat soak or poor fuel. Small restrictions can cause the O2 sensors to read a lean mixture, and so more fuel will be added to compensate. This can result in a rich mixture for the cylinders without injector problems, or even misfiring if the injector isn’t capable of injecting enough fuel. Fuel Pumps Overtime the fuel pump can wear out, but it might not necessarily fail catastrophically. While it may still be able to supply fuel at lower pressures, it may begin to struggle to provide fuel at higher pressures or for longer durations. Worn Piston Rings One of the major things that can happen over time is the piston rings will wear down, and this will allow for blow-by. Some of the high pressure air and fuel mixture combusting will pass by the pistons and travel along the cylinder walls into the crank case. This is pressure that should be pressing the piston down, so power is lost. It also means less compression as some of the air can escape as the piston travels upward on the intake stroke. Carbon Deposits On Intake Valves/Valve Seats If carbon deposits build up on the valves or valve seats, this can prevent the valves from closing properly. If an intake valve cannot fully close, it will allow air to escape during the compression stroke, effectively lowering the compression ratio. Carbon Deposits On The Piston If deposits build on the piston or cylinder walls, these deposits can create hot spots. These hot spots can result in engine knock if conditions allow for it. If the engine is capable, it will retard the ignition timing to reduce the likelihood of knock. By retarding the ignition timing, power is lost. Fouled Spark Plugs Spark plugs can build deposits with time. Inconsistent spark plug firing means you’re likely to misfire. Maintaining clean plugs ensures that the spark part of the equation doesn’t result in a loss of power.

We have a 3D printed EJ20 Subaru boxer engine, as well as a 22RE Toyota inline-four engine. We’ll start fairly basic and work our way through several different topics for each layout, including the four strokes, the firing interval and order, the vibrations of each layout, the packaging differences, the cylinder head differences, and finally a bit about the sound. Looking at either layout, they’re both based on the same four strokes. Intake, compression, power, and exhaust. Both engines fire one cylinder for every 180 degrees of crankshaft rotation, but they have slightly different firing orders. On each engine, we can see cylinders one, two, three, and four. For the boxer engine, the firing interval is one, three, two, four, while on the straight four it’s one, three, four, two, so the order of the last two cylinders firing is switched. On the boxer engine, you’ll notice the pairs of pistons move in and out together. This means that the primary forces when the piston reaches the top of the cylinder, as well as when they reach the bottom of the cylinder, are canceled out. On the inline four cylinder engine, it’s the same story, the primary forces cancel out as the pairs of pistons reach the top and bottom at the same time. When we get into secondary forces, however, the engines begin to differ. Secondary forces are created due to the piston traveling faster at the top half of the piston than at the bottom half, something I’ll include a link to in the description for a video that breaks it down in great detail. What you need to know though, is that when the piston reaches the very top of the cylinder, or the very bottom, the secondary force points up or out from the piston. Now with the boxer engine, since the pistons point opposite each other, these forces are balanced out, resulting in a very smooth running engine. For the inline four, all of the forces point in the same direction, and thus do not cancel each other out, causing the engine to vibrate unless balancing shafts are used. The boxer engine isn’t perfect, however, because the pistons do not perfectly align with each other, it creates a rocking moment which makes the engine want to rotate back and forth along the vertical axis. What’s fascinating, however, is that if you add two cylinders to either of these designs, whether it’s a boxer six or an inline six, you can perfectly eliminate all first and second order forces and moments. You might think the boxer six would have a rocking motion from the cylinder banks of three, but each bank of three cylinders cancels out the rocking motion of the other, unlike in a V6 configuration. The other biggest advantage of the boxer engine is the low profile, which keeps the center of gravity low and thus reduces the amount of load transfer you have in the car during braking, cornering, or accelerating, which improves grip. With a lower center of gravity, you can also reduce body roll and choose to use softer springs. Additionally, in the event of a collision, it’s easier to position the engine so that it goes underneath the passenger compartment, rather than into the passenger compartment, for improved safety. That’s not to say the inline four doesn’t have it’s own size advantages. Generally it’s a bit more compact, with only one cylinder head, and it’s not quite as wide as the boxer engine. This leaves more room for suspension geometry, and can also allow for a better steering angle, since the tires won’t have as much of an interference at full lock.

Working 3D Printed Chevy LS V8 Engine EE Shirts! - http://bit.ly/2BHsiuo Recommended Books & Car Products - http://amzn.to/2BrekJm Subscribe for new videos every Wednesday! - https://goo.gl/VZstk7 3D Printed LS3 Camaro V8 Engine Model: https://www.thingiverse.com/thing:1911808 V8 engines operates under the same basic principles as any other gasoline four-stroke engine. First the piston pulls in air and fuel as it moves downward, then it compresses that air and fuel as the piston moves upward. A spark plug fires, igniting the air/fuel mixture and forcing the piston downward. Finally the piston pushes out the exhaust gases on its way back up, before for the cycle repeats itself. In a V8 engine, this cycle is happening in 8 different cylinders, at different times. Instead of multiple cylinders firing at the same time, you want them to be spread out so that power delivery is smooth. For this Chevy V8, the firing or is 1, 8, 7, 2, 6, 5, 4, 3. With 8 cylinders, there is a cylinder firing for every 90 degrees of the crankshaft rotating, which means at any point in time, there are two cylinders on the power stroke. With regards to the valvetrain, the intake air comes from the top of the engine, and into the sides of the cylinder head. The exhaust flows to the sides of the engine, exiting the exhaust valves from the cylinder head. In this LS3 model, there is a single intake valve and a single exhaust valve, though it’s also common to see engines with two intake valves and two exhaust valves. The larger valve is the intake valve, and the smaller valve is the exhaust valve. The pushrod valvetrain gets its name from the metal pushrods which activate the rocker arms which open up the valves. The camshaft, located in the center of the V, has lobes on it which push the push rods up, opening the appropriate valves. For a full explanation of V8 engines, check out the video!

Mercedes-Benz CAMTRONIC | VIRTUAL ANIMATION

Mercedes-Benz CAMTRONIC | VIRTUAL ANIMATION

Mercedes-Benz CAMTRONIC is an innovative engine management system that reduces an engine's CO2emissions. It optimizes fuel consumption in the engine's frequently used lower partial load range by reducing losses relating to load change behavior. Mercedes-Benz equips its 1.6-liter variant of the M270 four-cylinder gasoline engine with the intake valve lift adjustment amongst others. The system operates mechanically, but is served by an electronically controlled actuator. The intake camshaft is made up of several components: two hollowed-drilled sub- shafts of equal size are mounted on the carrier shaft. The first sub shaft controls the intake valves of cylinders 1 and 2, and the second those of cylinders 3 and 4. The cams themselves take the form of a double-cam with two curved surfaces. The surface operating the valves via roller-type rocker arms is only half as wide as on a conventional cam, therefore the space requirement is the same. When the steeper half of the cam is active, the valve lift is increased and the valves remain open for longer. Switching to the flatter half of the cam shortens the valve lift and the valves close sooner. ►IF YOU LOVE CARS, YOU SHOULD SUBSCRIBE NOW TO GOMMEBLOG'S CHANNEL ►►► http://bit.ly/12ULPud ►SE AMI LE AUTO ..

Mercedes Benz Camtronic Valve Timing

Mercedes Benz Camtronic Valve Timing

Mercedes Benz Camtronic Valve Timing. Get the book here: https://www.createspace.com/4321251 Get the DVD-Video here: https://www.createspace.com/374294 Mercedes Benz introduced its Camtronic variable valve lift system on the M270, used on the C class series four cylinder engine in 2012. Called Camtronic, its main purpose is not to increase power, but to increase fuel efficiency. At light or part load, the Camtronic switches to a low lift cam profile to limit the amount of air intake, and at the same time the throttle butterfly can remain wide open, and reduce pumping loss. This is similar to BMW's Valvetronic system that uses an electric motor, and is discussed elsewhere in this series. But, the Camtronic is a 2 stage system, rather than continuously variable. The mechanism of Camtronic is pretty simple. The intake camshaft is served with a conventional variable cam phasing actuator at the end of it, as well as the Camtronic variable valve lift electric actuator normally mounted at the top of the head. The camshaft itself consists of an inner spline carrier shaft, and 2 hollow cam lobe pieces, each serving 2 adjacent cylinders. Mercedes Benz engineers refer to these as cam-pieces, of which the first controls the intake valves of cylinders 1 and 2, and the second those of cylinders 3 and 4. Each cam has 2 cam lift profiles, or low and high lift. The cam profile that is engaged depends on the ... Get the whole story right here in this video... Enjoy...
