The new Polo GTI, in what Volkswagen is calling “textbook downsizing”, is powered by a new 1.4-liter The engine, which delivers 132 kW (177 hp), is coupled with a 7-speed DSG as standard. By comparison, its direct predecessor with regard to power—equipped with a 132 kW 1.8-liter
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. O 2 (% wt). Cairns et al. SAE 2009-01-0138).
those which do not favor one technology over another through consumer incentives, federal subsidies, testing standards or technology-specific credits. The quickest and most cost-effective way to achieve our energy usage goals is through faster adoption of fuel-efficient downsized gasoline and diesel engines.
As a point of comparison, the US EPA’s proposed national CO 2 emissions standards for light-duty vehicles under section 202 (a) of the Clean Air Act would require these vehicles to meet an estimated combined average emissions level of 250 grams/mile of CO 2 —155.26 g/km—in model year 2016. Hariher Balasubramanian.
Fuel mass flow comparison shows Pinnacle engine ahead at just about all points in the map. Right now, the emissions standard in the target market is Euro 4. We did another study with FEV, projecting our data onto a turbo downsized application; we get nearly 50% improvements in common automobiles. Click to enlarge.
CO 2 emissions of the C 180 in comparison to its predecessor [t/car]. The CO emissions of the new C-Class during operation are 76 % below the level stipulated by the Euro 6 standard that comes into effect in 2015. The C 180 with manual transmission shows a drop in fuel consumption in comparison to its predecessor from between 7.6
Although real-world fuel economy improvements from GDI technology alone are close to 1.5%, they can reach 8% by downsizing and turbocharging the engine, which can be achieved on GDI engines without loss of power compared to PFI engines. All the vehicles were tested using commercial gasoline that met the summertime California fuel standards.
Under California’s vehicle emissions ratings, PZEVs (Partial Zero Emission Vehicles) meet SULEV (Super Ultra Low Emission Vehicle) tailpipe emission standards and also have zero evaporative emissions. The SULEV standard, established under the current LEV II regulation, is equivalent to the Federal Tier 2 Bin 2 standard.
The committee’s estimates are based on a variety of factors including recent reports from regulatory agencies and other sources; component cost estimates from suppliers; discussions with experts; and comparisons of prices and fuel consumption of similar vehicles. The study was sponsored by the National Highway Traffic Safety Administration.
Major automotive suppliers see national fuel economy standards as important for long-term planning and investment and don’t want to see them altered by US policymakers, according to a first-of-its-kind industry survey commissioned by CALSTART and conducted by Ricardo Energy & Environment.
Engine downsizing and downspeeding are two strategies that can be applied to gasoline and diesel engines to improve vehicle fuel economy. The also created revised shift schedules for the baseline gear ratios for the turbo for comparison. The team presented its work at the SAE 2012 World Congress.
Based on test work already carried out, Ricardo estimates that a fuel economy improvement of up to 30% is possible with no loss of power or performance, using a downsized EBDI engine in place of currently available gasoline powertrain technology. Comparison of different ethanol blend levels in EBDI engine. fuel economy improvement.
Diesel vehicles have had a rough time penetrating the US light-duty vehicle market, reflecting outdated negative perceptions, higher fuel prices for diesel than for gasoline, the cost of complying with stringent US emission standards, and rapidly improving gasoline engines. miles per gallon in model year 2016, and 49.1 per year.
IROX 2 joins Federal-Mogul’s family of IROX technologies which reduce friction and improve the wear resistance and fatigue limit of the bearings used in today’s highly evolved downsized engines. Sample bearings with the IROX 2 coating are already with customers for evaluation and series production will commence later this year.
Behind the targets is a significant amount of modeling, including revisions to certain aspects of the Volpe modeling process, such as the inputs, data, modeling techniques, and the constraints used in assessing appropriate stringency for future CAFE standards. This reduces pumping losses at lighter loads in comparison to a larger engine.
The resulting higher BMEP levels allow downsizing of the engine at equivalent vehicle performance. Furthermore, by enabling higher CR, downsizing and downspeeding, E85 DI + gasoline PFI makes the engine more efficient in itsusee of gasoline. Earlier post.) The diesel requires more complex and expensive aftertreatment systems.
The panel, moderated by Jesse Schneider, BMW, included Takashi Moriya, Senior Chief Engineer at Honda R&D; Dr. Will James, Manager, Safety, Codes, and Standards at the US Department of Energy (DOE); and Dr. Ralph Clague, Head of Motive Systems and Architecture, Intelligent Energy. Earlier post ). kW/L–approximately a 60% improvement.
Fiesta features Twin Independent Variable Camshaft Timing (Ti-VCT) ( earlier post ) which allows the engine to be downsized for fuel economy while continuously optimizing camshaft phasing for throttle response, performance and flexibility. The Ford Fiesta’s 1.6-liter
3 B-Cycle gasoline engine is the first example of Volkswagen’s “Rightsizing” strategy—an engine development strategy that looks to for the optimal balance of displacement, output, torque and efficiency based on vehicle class and real-world operating conditions, rather than just seeking to downsize. By comparison, the 2017 Tiguan with 2.0L
General project targets were to deliver diesel-like or better fuel economy using E10 gasoline (RON91), and to achieve low engine-out NO x and PM using low temperature combustion, the intention being to avoid the cost of aftertreatment for NO x and PM, in addition to meeting more stringent standards. DOE UFEV program targets.
Reaching this level is ambitious but achievable, the paper noted; the enacted fuel economy standards around the world require annual improvements of up to 4.7%. —“International comparison of light-duty vehicle fuel economy”. The trend is toward smaller displacements (downsizing). Engine power. Source: GFEI. Source: GFEI.
BCG comparison of the CO 2 reduction potential and cost of different technologies. EVs will likely account for approximately 8% of new car sales in Europe by 2020, supported by consumers’ higher willingness to pay for green technologies, the region’s high emissions standards, and high gasoline and diesel fuel taxes.
These individual class curves are then sales weighted to estimate fleet average compliance costs for a range of potential CO 2 standards. With respect to light-commercial vehicles, CO 2 standards as low as 90–100 g/km (NEDC) can be achieved with few or no electric vehicles in the new-vehicle market. Source: The ICCT. Click to enlarge.
l/100 km (39 mpg US) with 158 g CO 2 /km) and has a range of up to 1,500 kilometers (932 miles) when equipped with an optional larger tank (93 liters vs. the standard 70 liters, the latter good for 1,150 km or 715 miles). Emissions standard. The M-Class is a story of success. With more than 1.2 BlueTEC diesel units. Earlier post.)
Idle reduction technologies could provide 6% reduction in overall fuel consumption for Class 8 long-haul trucks with sleeper cabs, which is nearly 30% of the 20% reduction in the fuel consumption required to meet the proposed EPA/NHTSA 2017 fuel efficiency standards. Recommendation 6-4. Two of the project teams (Cummins, Inc. Finding 8-6.
Despite its efficiency, the Golf TSI BlueMotion with the 85 kW / 114 hp downsized 999 cc EA211-series engine reaches 100 km/h in 9.7 Golf Comparisons. Numerous assistance systems are fitted as standard to the Golf TSI BlueMotion. seconds and goes on to a top speed of 204 km/h (127 mph). engine) introduced in 1975.
Other dimensions of the Mark VIII were larger in all directions, a stark contrast to the extreme downsizing implemented on Mark VI, a measure pushed further by the tidy proportions of the Mark VII.& Worth a quick comparison, the equivalent Thunderbird weighed 3,536 pounds with a V6 engine or 3,725 with the V8.
The flywheel is downsized to give a continuum between shift of gears, else unlike a ICE engine, when you take your leg off the pedal, the motor goes zero torque when you are re-engaging gears. ARAI homologation work is going on - but electric tractor standards are still WIP at ARAI. So we have a clutch that connects to a huge flywheel.
Since it can refuel from a standard household outlet and from a gasoline station, it needs no new infrastructure. Appendix B: Car of the Future: A Comparison of Alternative Vehicles. More information on e-mile comparisons is given by Reference Nº 2. How PHEV enhances The Electric Infrastructure. Conclusions. slow charge.
In one way, the program in question—the Renewable Fuel Standard (RFS)—is a relic from a bygone era. Environmental Protection Agency (EPA), which stewards the RFS, had repeatedly downsized the targets by nearly 25 percent. Because that’s really the comparison that you care about.”. By the mid-2010s, the U.S. In 2016, a U.S.
