GKN ramps up new fuel saving hybrid bus technology
11/13/2014
GKN Land Systems is ramping up production of a new hybrid technology for buses that will enable operators to save fuel, reduce fares and make some routes more viable. Demand for the company's Gyrodrive electric flywheel hybrid is growing following successful trials in London and the start of UK production.
GKN Land Systems CEO Phil Swash said: "Gyrodrive is the first hybrid technology that makes economic sense for bus operators. Gyrodrive is part of GKN's strategy to offer customers new hybrid and electric driveline solutions that compliment our existing portfolio of technologies. In the next five years hybrid and electric systems will become increasingly more important to commercial, off-highway and agricultural vehicles. As we increase production volumes, GKN's economies of scale will make Gyrodrive's cost and benefits compelling for many commercial vehicle operators."
The Gyrodrive system is a lower cost alternative to conventional battery hybrids. The upfront investment is a fraction of the cost of existing hybrids. With real-world fuel savings of up to 25%, the payback period for bus operators is three to four years. The system is smaller than conventional battery or super-capacitor hybrid units, which means it does not compromise seating or passenger capacity and can be retro-fitted to existing fleets.
Jules Carter, Head of Innovation at GKN Land Systems, said: "Few companies can match GKN's expertise in composites, aluminium, and powder metallurgy, its understanding of driveline vibration and harmonics or its high-volume production capabilities. Leveraging all that expertise as we scale up production will enable us to make Gyrodrive viable for a broad range of commercial vehicle applications."
Gyro
drive uses a high-speed composite flywheel paired with an innovative GKN EVO electric motor to regenerate the energy normally lost during braking. When the driver brakes, a traction motor on one of the axles slows the vehicle and generates electricity simultaneously. The electricity charges the flywheel, spinning it at up to 36,000rpm. When the driver accelerates, Gyrodrive returns the energy to the wheels, boosting power, saving fuel and reducing emissions.
The electric flywheel started life in motorsport. In June, GKN's Gyrodrive system helped power Audi Motorsport's hybrid race car to a third consecutive victory in the gruelling Le Mans 24 Hour endurance race.
"Bus operators want certainty on the fuel and cost savings and the reliability," said Jules Carter. ""Buses are the perfect first step for Gyrodrive as GKN builds production volumes, said Carter. "Extensive trials in London proved the technology offers operators certainty on the savings and the reliability. With buses an important part of transport policies in the developing world's fast-growing megacities, Gyrodrive has the potential to play a global role in improving city air qualit
y."
Gyrodrive will also help improve the efficiency of other commercial vehicles used in cities. Refuse and delivery truck applications are planned, so are agriculture and construction vehicles. Heavy vehicles with 'stop-and-go' or 'back-and-forth' duty cycles consume a lot of energy that Gyrodrive can recover and regenerate. In the longer term, as volumes increase and costs reduce, GKN expects Gyrodrive to be a viable option for mass-production vehicles.
The Federal's pistol slid into its holster and his sabre flashed out. He threw its curved point up in a splendid salute. Ferry saluted with his straight blade. Then both swords rang back into their scabbards, and Jewett whirled away toward his column. For a moment we lingered, then faced to the left, trotted, galloped. Over the fence and into the road went he--went I. Down it, as we crossed, the blue column was just moving again. Then the woods on the south swallowed us up. "All right, sir." that before. Meanwhile the parallelism between Thought and Extension was not exhausted by the identification just analysed. Extension was not only a series of movements; it still remained an expression for co-existence and adjacency.412 Spinoza, therefore, felt himself obliged to supply Thought with a correspondingly continuous quality. It is here that his chief originality lies, here that he has been most closely followed by the philosophy of our own time. Mind, he declares, is an attribute everywhere accompanying matter, co-extensive and co-infinite with space. Our own animation is the sum or the resultant of an animation clinging to every particle that enters into the composition of our bodies. When our thoughts are affected by an external impulse, to suppose that this impulse proceeds from anything material is a delusion; it is produced by the mind belonging to the body which acts on our body; although in what sense this process is to be understood remains a mystery. Spinoza has clearly explained the doctrine of animal automatism, and shown it to be perfectly conceivable;569 but he has entirely omitted to explain how the parallel influence of one thought (or feeling) on another is to be understood; for although this too is spoken of as a causal relation, it seems to be quite different from the logical concatenation described as the infinite intellect of God; and to suppose that idea follows from idea like movement from movement would amount to a complete materialisation of mind; while our philosopher would certainly have repudiated Mr. Shadworth Hodgson’s theory, that states of consciousness are only connected through their extended substratum, as the segments of a mosaic picture are held together by the underlying surface of masonry. Nor can we admit that Spinoza entertained the theory, now so popular, according to which extension and consciousness are merely different aspects of a single reality. For this would imply that the substance which they manifest had an existence of its own apart from its attributes; whereas Spinoza makes it consist of the attributes, that is to say, identifies it with their totality. We are forced, then, to conclude that the proposition declaring thought and extension to be the same thing570 has no413 other meaning than that they are connected by the double analogy which we have endeavoured to explain. “Oh, he’s welcome to it,” Sandy cried. “I’ve turned over a new leaf!” “But—are they?” He pulled a wire out a trifle from the sheath. The sergeant spent more time upon the oaths with which he embellished the counter-question as to how he should know anything about it, than would have been consumed in a civil explanation. "Doctor, he can't die. He mustn't die," said Shorty in agony. "The regiment can't spare him. He's the best soldier in it, and he's my pardner."

"Holy smoke, look there," gasped Monty Scruggs, as a company of rebel cavalry came tearing over the hill in front, to the assistance of their comrades. "That's about it," answered Shorty disdainfully. "That's the way with all cavalry, dad-burn 'em. They're like a passel o' fice pups. They're all yelp and bark, and howl and showin' o' teeth. They're jest goin' to tear you to pieces. But when you pick up a stone or a club, or git ready to give 'em a good kick they're gone, the devil knows where. They're only an aggravation. You never kin do nothin' with 'em, and they kin do nothin' with you. I never kin understand why God Almighty wasted his time in makin' cavalry of any kind, Yank or rebel. All our own cavalry's good for is to steal whisky and chickens from honest soldiers of the infantry. The infantry's the only thing. It's like the big dog that comes up without any special remarks, and sets his teeth in the other dog. The thing only ends when one dog or the other is badly whipped and somethin's bin accomplished." "Mmm." Reuben started out of the half-waking state into which he had fallen. It was late in the afternoon, the sunlight had gone, and a wintry twilight crept up the wall. Maude the dairy-woman was looking in at the door. It was about a month subsequent to this, that one morning, as Turner was making the anvil ring with the ponderous strokes of his hammer, two retainers from the castle entered the shed, and delivered an order from De Boteler for his immediate attendance. Wat laid the hammer on the anvil, and, passing the back of his right hand across his forehead, to clear away the large drops that stood there, looked with a kind of smile at the men as he said, HoME泷泽萝拉四部和集下载
