How Dynamic Skip Fire Works – Variable Displacement Engines

How Dynamic Skip Fire Works - The Ultimate Cylinder Deactivation EE Shirts! - http://bit.ly/2BHsiuo Recommended Books & Car Products - http://amzn.to/2BrekJm Subscribe for new videos every Wednesday! - https://goo.gl/VZstk7 Dynamic Skip Fire is a new Tula/Delphi technology that aims to be the ultimate form of cylinder deactivation. It allows for fully variable cylinder deactivation, meaning if you have a V8 engine, it can run on one cylinder, two cylinders, or any number of cylinders up to all eight cylinders. This video will explain how the cylinder deactivation works, what the advantages are, pumping losses, and what real world efficiency benefits can be expected. The majority of the benefit of this system comes from reducing pumping losses. That is to say, it's more efficient to run one cylinder at high load for a certain amount of power, versus running four cylinders at low load for that same amount of power. Dynamic Skip Fire technology will make it's debut in the 2019 Chevrolet Silverado with 5.3L and 6.2L V8 engines, called "Dynamic Fuel Management."

Electric Superchargers – How Audi Is Eliminating Turbo Lag

How Do Electric Superchargers Work? EE Shirts! - http://bit.ly/2BHsiuo Recommended Books & Car Products - http://amzn.to/2BrekJm Subscribe for new videos every Wednesday! - https://goo.gl/VZstk7 The Audi SQ7 is powered by a 4.0L sequential turbo diesel V8. It's good for about 435 horsepower and 660 lb-ft of torque, which is great, but the fun doesn't stop there. In order to eliminate unresponsive nature of turbocharged engines, Audi has fitted the car with an electric supercharger, the first in a production vehicle. This means adding an onboard 48V system that can handle the additional power requirements of the electric powered compressor (EPC), which at full throttle can produce 7 kW of power, enough to spin the compressor wheel up to 70,000 RPM in just a quarter of a second. Full details of how this system works in the video, as well as animations. Engineering Explained is a participant in the Amazon Influencer Program. Don't forget to check out my other pages below!

Volkswagen’s V5 Engine — When A VR6 Is Too Big

What Is A V5 Engine? What Happened To V5 Engines? EE Shirts! - http://bit.ly/2BHsiuo Recommended Books & Car Products - http://amzn.to/2BrekJm Subscribe for new videos every Wednesday! - https://goo.gl/VZstk7 V5 engines are a rare anomaly in the automotive world. Honda used a 1.0L V5 engine in motorcycles, with great success, though the setup hasn't been seen in many production cars. VW produced a V5, or more accurately a VR5, for its packaging and power benefits versus a larger VR6, or a smaller inline four cylinder. The VR5 engine style, though only requiring two camshafts (SOHC, 2 valves per cylinder, or DOHC, 4 valves per cylinder), has its complications. The intake and exhaust paths are shorter for two of the cylinders, the crankshaft geometry is offset from the cylinder center lines, and ultimately it's not much more powerful than an inline four cylinder. Check out the video for full details about how the engine works. Engineering Explained is a participant in the Amazon Influencer Program. Don't forget to check out my other pages below!

Flatplane vs Crossplane V8 Engines – Which Is Best?

Flatplane vs Crossplane V8 engines. Foreign vs. domestic. What is a flatplane crankshaft? What is a crossplane crankshaft? These engines get their names from the design of the crankshaft, and have key distinct differences. Flatplane engines have the primary forces balanced out, so the crankshaft can be light and fast revving. Crossplane V8 engines have the secondary forces balanced out, making them very smooth with the addition of counterweights to balance out the primary forces.

5 Reasons Diesel Engines Make More Torque Than Gasoline

Why Do Diesel Engines Make So Much Torque? EE Shirts! - http://bit.ly/2BHsiuo Recommended Books & Car Products - http://amzn.to/2BrekJm Subscribe for new videos every Wednesday! - https://goo.gl/VZstk7 If you compare gasoline and diesel models of the same vehicle, the diesel engine tends to have far more torque. Why is this? In this video we'll discuss the major differences between diesel and gasoline engines, that result in the diesel engine producing significantly more torque. From the compression ratio, the speed of combustion, the bore vs stroke ratio, the use of turbocharging, and the energy density of diesel, there are many logical reasons why it's chosen for high torque applications.

How Fast Could A Tesla Roadster Hit 60 MPH On Mars?

If SpaceX Sent A Roadster To Mars, How Fast Could It Hit 60 MPH? EE Shirts! - http://bit.ly/2BHsiuo Recommended Books & Car Products - http://amzn.to/2BrekJm Subscribe for new videos every Wednesday! - https://goo.gl/VZstk7 SpaceX sent a Tesla Roadster out into space on the Falcon Heavy, and it did not land on Mars. Which begs the question, if a new Tesla Roadster was on Mars, how long would it take the Roadster to accelerate to 60 MPH? Okay, so maybe it doesn't beg the question, but you're probably at least mildly curious to find out at this point. We'll need to determine the frictional coefficient of the Tesla Roadster's tires (and assume we'll be driving on pavement on Mars, or something with similar grip to asphalt), and then apply this to a vehicle accelerating on a planet with a fraction of the gravity of planet Earth.

How The Acura NSX Connects Man To Machine

How Engineers Connected Man And Machine In the Acura NSX Engineering A Feeling Brought To You By Acura - https://www.acura.com Subscribe for new videos every Wednesday! - https://goo.gl/VZstk7 Acura believes the best way to engineer a feeling, to become one with the car, is the idea of zero-delay. Basically any inputs from the driver must result in immediate outputs from the car. For example, all of the interfaces that you as a driver touch, must react seamlessly. The throttle, the brakes, the steering, and the shifting. If there’s a delay between when you act, and when the car reacts, you feel disconnected from the driving experience, and it’s that delay that Acura sought to eliminate. Typically with turbocharged engines, there’s a response delay in the throttle as a result of turbo lag. In the NSX, this delay is eliminated by using the immediate torque of the three electric motors. All three motors provide peak torque up to 2,000 RPM, and by 2,000 RPM the engine is ready to provide peak torque all the way to 6,000 RPM. The result is an instantaneous response to your throttle inputs, and a huge range of available torque regardless of the engine speed. For the steering, the NSX uses an electronically assisted power steering rack with a variable ratio which gets progressively tighter as you turn the wheel. The ratio starts at 12.9, so you have quick turn in without much steering angle. But having a car that’s instantly responsive to your steering inputs isn’t just about the steering ratio. With the mid-engine design, the vehicles mass is located towards the center, and this reduces the polar moment of inertia, allowing for the NSX to change directions more quickly. The body of car is a multi-material space frame that’s extremely rigid, so whenever steering input is asked for, it’s immediately answered. On top of the rigid body and steering system, Acura also uses direct yaw control. Acura’s agile handling assist can brake the inside tires when turning into a corner to help prevent understeer, or brake the outside tires to help prevent oversteer. Simultaneously, the twin motor unit can provide negative torque to the inside tire in a corner to create a yaw moment, as well as accelerate the outside motor to help pull the car out of a corner. The motors can act independently of throttle control, meaning the twin motor unit can can send power instantly...
