Mack unveils first turbine hybrid refuse truck

Mack unveils first turbine hybrid refuse truck

Mack Trucks revealed the first Class 8 refuse truck with Wrightspeed’s turbine supported at WasteExpo 2016. A Mack LR that was retrofitted with the Wrightspeed Route 1000 was on display at the truck manufacturer’s booth inside the Las Vegas Convention Center. Mack is the first OEM that will be testing the alternative driveline.

The Wrightspeed Route powertrain uses electricity to deliver 100 percent of the vehicle’s propulsion. The system features an advanced plug-in-capable battery pack that enables a purely electric range of up to 24 miles. When the batteries’ charge is depleted, an 80 kW, fuel agnostic Fulcrum Turbine Generator, which can operate on natural gas or diesel fuel, recharges the batteries, enabling Route-equipped vehicles to have unlimited range with refueling. Additional recharging comes from the Route’s 730 kW regenerative braking system, which generates electricity as the vehicle comes to a stop. Regenerative braking helps Route-equipped vehicles to cut down on maintenance costs, as braking force – and subsequent brake wear – is significantly decreased.

Electricity from the battery pack powers four Geared Traction Drive (GTD) electric motors, enabling the Route powertrain to power vehicles up to 66,000 pounds on grades as steep as 40 percent. With full torque available from zero rpm, the Route provides a driving experience comparable to diesel-powered trucks.

Volvo Group has presented the first self-driving mining truck. The truck is part of a research and developement programm on autonomous vehicles with the focus on mining. Volvo is especting highere productivity and improved safety. The project is a cooperation between Volvo Group and Saab. The Volvo FMX tipper truck can drive, navigate and unload on- and underground. The truck uses sensors and GPS to operate safely. Moving items like other vehicles are spotted by the sensors.

Volvo Trucks reduces fuel consumption by 30% after aerodinamics improvement

Volvo Trucks reduces fuel consumption by 30% after aerodinamics improvement

Almost one-third lower fuel consumption. Volvo Trucks’ new concept vehicle shows how it is possible to drastically boost productivity in long-haul operations. Among the secrets behind these remarkable fuel savings are aerodynamic design and lower kerb weight. With support from the Swedish Energy Agency, Volvo Trucks has developed a new concept vehicle, the Volvo Concept Truck. It is the result of a five year long research project aimed at creating more energy-efficient vehicles. The new concept truck cuts fuel consumption by more than 30 %.

"We continuously work on developing more energy-efficient vehicles. This is a high-priority area both out of environmental concern and in order to reduce our customers' costs. We're proud to be able to drive this development. Our concept truck showcases the immense power of on-going technical advances," says Claes Nilsson, President and CEO Volvo Trucks.

One of the key factors behind the low fuel consumption is the massive 40 % improvement in aerodynamic efficiency that has benefited both the tractor and trailer. "We've modified the entire rig and optimised it for improved aerodynamics as much as possible. For instance, we use cameras instead of rear-view mirrors. This cuts air resistance, so less energy is needed to propel the truck," explains Åke Othzen, Chief Project Manager at Volvo Trucks.

In addition to the aerodynamic improvements, the concept vehicle is fitted with newly developed tyres with lower rolling resistance. The trailer weighs two tonnes less than the reference trailer, which translates into either lower fuel consumption or the possibility of higher payload. The project also includes an improved driveline. The rig was test driven on Swedish roads in autumn 2015.

Since the concept vehicle is part of a research project it will not be available on the market. However, some of its aerodynamic features have already been implemented on Volvo Trucks' series-produced vehicles, and more of its solutions may be fitted in the future.

The aerodynamic improvements:

- Optimised aerodynamic trailer and tractor.

- In order to reduce air resistance, the conventional rear-view mirrors have been replaced by cameras, which have the added advantage of offering better visibility and increased safety.

- Aerodynamically optimised chassis side-skirts cover the rear wheels on the tractor and all the trailer wheels.

- Aerodynamic spoilers extend the trailer and cut air resistance.

- Optimised air flow for the engine's cooling system

- Minimised air resistance at the front of the tractor, the wheel housings and entry steps.

So what is good On-Page SEO?First your keyword must appear in the title.Then it must appear in the URL.You have to optimize your keyword and make sure that it has a nice keyword density of 3-5% in your article with relevant LSI (Latent Semantic Indexing). Then you should spread all H1,H2,H3 tags in your article.Your Keyword should appear in your first paragraph and in the last sentence of the page. You should have relevant usage of Bold and italics of your keyword.There should be one internal link to a page on your blog and you should have one image with an alt tag that has your keyword....wait there's even more Now what if i told you there was a simple Wordpress plugin that does all the On-Page SEO, and automatically for you?
