variant but with fueleconomy of a strong hybrid. HyBoost achieves this by combining aggressive 50% downsizing of the engine with an electric supercharger for transient low-speed performance, and a micro-hybrid stop-start and energy recuperation systems, Boggs said. Downsizing the 2.0-liter Click to enlarge.
The XC60 Plug-in Hybrid Concept was introduced at the Detroit Auto Show. The 2012 XC60 carries an EPA fueleconomy rating of 20 mpg US (11.8 By contrast, the XC60 concept plug-in would offer an estimated combined fueleconomy rating in continuous driving in hybrid mode of 50 mpg US (4.7 Click to enlarge.
This marks Toyota’s first downsizing of its HSD technology. This engineering solution targets the independent powering of the air-conditioning unit for improved full hybrid powertrain fueleconomy. The smaller Prius v introduced in January at the Detroit show features a NiMH pack.).
A study by engineers from Mahle Powertrain Ltd and BP found strong synergy between spark ignition (SI) engine downsizing and fuel containing low-to-moderate amounts of alcohol, including ethanol and butanol. The team presented a paper on their work at the recent SAE 2009 World Congress in Detroit. Cairns et al.
The A dvanced C ombustion C oncepts— E nabling S ystems and S olutions (ACCESS) is developing advanced combustion control concepts along with with an enabling system, subsystem and component level solutions for the management of multi-mode/multi-fuel combustion events. HCCI range extension with boosting. Source: Bosch. Click to enlarge.
The company presented these latest test results in a paper at the SAE 2012 World Congress in Detroit. The results represent a light-load indicated efficiency improvement of 15-30% (up to 40.9%). Net indicated efficiency of the Pinnacle Opposed-Piston engine, CR = 15:1, 87 Octane. Source: Pinnacle. Click to enlarge.
Improving battery power to such as level would further enable hybridization to near-HEV levels as well as engine downsizing, thereby enabling fueleconomy improvements beyond the current 10-15% MHEV limit. Finally, partial hybridization using the 48V powertrain may be integrated to improve fueleconomy.
Hyundai introduced the Hybrid version of the seventh-generation Sonata at the North American International Auto Show in Detroit. Hyundai expects the 2016 Sonata Hybrid to improve fueleconomy more than 10%. The 2016 Sonata Hybrid features a downsized 2.0-liter
A study by a team from Ford Motor Company and AVL has concluded that a mid-level ethanol blend—greater than E20 but less than E40—appears to be attractive as a long-term future fuel for the US for use in engines optimized for the higher octane blend. Downsizing/downspeeding. Volumetric fueleconomy.
This year''s Detroit Auto Show is a little light on truly green car content, so most attention will instead turn to downsized engines and vehicles offering subtle improvements in fueleconomy.
Ford led the Detroit automakers while achieving the greatest percent reduction in smog-forming emissions of any manufacturer evaluated. To determine GHG emissions, UCS considered the fueleconomy, fuel type, and sales volume of each type of vehicle sold by each automaker in the 2013 model year (MY2013). Methodology.
Samardzich is expected to detail EcoBoost production plans as well as the next three EcoBoost engines scheduled for launch by the end of the year during remarks Tuesday at the SAE World Congress in Detroit. The EcoBoost F-150 is expected to deliver best-in-class fueleconomy along with the power and towing capability of a V-8.
” Bunker spent the bulk of his presentation describing the new medium- and heavy-duty fueleconomy and greenhouse gas regulations from EPA and the Department of Transportation. The future that we point to [is] very conventional-looking engines.” Earlier post.) In his talk during the opening plenary, Dr.
SAE’s 2012 High Efficiency IC Engine Symposium in Detroit—the second as an immediate precursor to the SAE World Congress—opened on Sunday with a consideration of several alternative engine designs: opposed piston 2-stroke (Achates Power); variable compression ratio (MCE-5); split cycle (Scuderi); and advanced rotary (Liquid Piston).
Ford is focused on lightweighting as a key enabling technology for lowering fuel consumption in combustion-engined vehicles (ICE) and for extending the range—and the size—of battery electric vehicles (EVs). Taking the displacement down gets you on a percentage basis the best fueleconomy value versus other technologies.
Ford unveiled the new 2013 Ford Fusion midsize sedan, with conventional gasoline engine; hybrid featuring a next-generation of Ford’s hybrid system; and plug-in hybrid versions at the Detroit Auto Show—the first production sedan to offer that trio of options. The new Fusion also points to the next Ford Mondeo for world markets.
Ford unveiled its strategically important next-generation Ford Focus in both four-door sedan and five-door hatchback styles at the 2010 North American International Auto Show (NAIAS) in Detroit. Duratec I-4 unit while contributing to projected fueleconomy gains of more than 10%. “People downsize cars, not expectations.
Among their general findings are: Increasing battery power in plug-in hybrids (10-, 20- and 40-mile AER, from low to high power) had little effect on fuel consumption results because the battery power can provide most of the driving on the test cycles, so the fueleconomy only differs slightly. Brooker, A.; Thornton, M.;
Testing was also conducted at the DTNA Detroit engineering facility to demonstrate engine efficiency by achieving 50.2% The Freightliner SuperTruck uses a downsized and downsped 10.7-liter This reduces friction, and increases efficiency and fueleconomy. Detroit rear axles were upgraded for the Freightliner SuperTruck.
which hopes to sell cars here in three to five years, used the Detroit Auto Show to display a prototype sedan it says can run 60 miles on batteries developed in-house and another 190 miles on a gas/electric system. Detroits horsepower jockey insists the Volt will be his crowning achievement--and his swan song. Detroit Free Press ).
