Changes in the attributes (clockwise from upper left, weight, power, fuel economy and torque) of the Honda Accord over time as an example of fleet trends in the US. In contrast, fuel economy actually increased by 15% during that period. Knittel, 2009. Click to enlarge. Knittel, 2009. Knittel, Christopher R.
Ricardo will assist Lifan Automobile Group based in Chongqing, China, with the development of a family of highly downsized gasoline engines capable of meeting future Chinese and international fuel economy and emissions regulations.
Utilizing technologies such as turbocharging, direct injection, twin independent variable camshaft timing (Ti-VCT) and six-speed transmissions, the upgraded powertrain portfolio will deliver more than 20% in fuel economy improvement to Ford’s passenger vehicle fleet in China by 2015 while reducing tailpipe carbon dioxide emissions by 20%.
The Automobile Division of the Institution of Mechanical Engineers has awarded its Prize for the Environment to Ricardo, Ford Motor Company, Controlled Power Technologies and Valeo engineers for their paper HyBoost—An Intelligently Electrified Optimized Downsized Gasoline Engine Concept. Earlier post.). Earlier post.)
Anhui Jianghuai Automobile Group Co Ltd (JAC) and Ricardo are collaborating on a project to develop the Ricardo HyBoost concept ( earlier post )—a combination of low-cost technologies to deliver improved performance and fuel economy which featured recently in the Ricardo Centenary celebrations —into volume production on a JAC vehicle.
Automakers are turning to downsized turbocharged engines to satisfy more stringent global fuel economy and emission regulations and customer demand for better-performing vehicles. In addition to improving fuel efficiency, downsized turbocharged engines also reduce harmful exhaust emissions.
FEV performed engine mappings in a dynamometer test cell to evaluate the fuel economy of Pinnacle’s TP90 scooter engine compared to a benchmark engine (N15) from Pinnacle’s Asian OEM partner. This combination of variable compression ratio and our operating mode gets us huge fuel economy wins. That’s what needed all over Asia.
DeCicco’s analysis shows that optimizing internal combustion engines plus rising adoption of grid-free hybrids will enable new fleet fuel economy (unadjusted) to reach 52 mpg (4.52 Adjusted on-road fuel economy correspondingly would be 41 mpg (5.74 —A Fuel Efficiency Horizon for US Automobiles. L/100km) by 2035.
To address this request, the NRC formed the Committee on the Assessment of Technologies for Improving Light-Duty Vehicle Fuel Economy. Further, the benefits of some technologies are not completely represented in the tests used to estimate corporate average fuel economy (CAFE).
Describing its product goals and tracking progress toward its 2020 manufacturing priorities in its 2012 Sustainability Report , General Motors reaffirmed its commitment to further reduce the energy used and the environmental impacts of building and operating an automobile. Earlier post.).
Estimated price increases are based on current economic conditions and the concept of “incremental retail price equivalent (RPE) cost,” which represents the average additional price consumers would pay for a fuel economy technology. For example, the report notes the promise of cylinder deactivation, turbocharging and downsizing.
The presence of low-speed pre-ignition is considered a major impediment to automobile manufacturers’ efforts to aggressively downsize engines to reduce carbon dioxide emissions. This four-year program expands on earlier efforts to improve gasoline engine technology for future emissions and fuel economy requirements.
These innovative technologies include catalytic and evaporative emissions controls, advanced fuel injection, downsized GDI engines, turbochargers, cooled-EGR systems, dynamic cylinder deactivation, OBD systems as well as hybrid and fuel cell powertrain systems, batteries, electric components and controls.
improvement in fuel economy in operation over the Japanese 10-15 cycle. When downsizing, Kato said, using a turbocharger or supercharger to offset the decrease in output can result in a fall in the knocking limit as the boosting pressure rises, causing the thermal efficiency to fall as well. and back again. Kadota et al.
The all-new electronic limited slip differential, Ultra Posi is designed for front and rear-wheel drive vehicles, performs comparably to four-wheel-drive and all-wheel-drive systems and provides up to a 10% savings in fuel economy, Eaton says. China’s largest independent automaker, Chery Automobile Co. Tiggo, 1.3S V6 and 4.2L
Also, new-car average fuel economy fell in April, and Fiat Chrysler Automobiles is reportedly working on a downsized turbocharged 4-cylinder engine for fuel efficiency. Today, Tesla aims to produce 500,000 cars per year by 2018, rather than 2020 was originally stated. All this and more on Green Car Reports.
On 15 Sep, NHTSA and the US EPA proposed a joint rulemaking on fuel economy and greenhouse gas emissions for light duty vehicles: an average new car 34.1 mpg if the automotive industry were to meet this CO 2 level just through fuel economy improvements.) ( Earlier post.). Turbocharging and downsizing: 26% for cars, 15% for trucks.
The analysis used by federal agencies to set standards for fuel economy (CAFE) and greenhouse gas emissions for new US light-duty vehicles from 2017 to 2025 was thorough and of high caliber overall, according to a new report from the National Research Council. UMTRI Survey: US drivers want better fuel economy, don’t care how.
which already operate in numerous sectors and which can be carried over to the automobile. In the meantime, Renault will carry over its downsizing policy to cover utility vehicles with the replacement of its current 2.5-liter The development of new consumer patterns (monthly subscriptions, pay as you go schemes, etc.)
China’s fourth largest car manufacturer Chongqing Changan Automobile Co and Orbital Corporation Limited have formed a joint development to work on a concept engine. It is hoped that with fuel economy improvements, the Euro IV emission levels will be achieved.
The electrification of the automobile is inevitable." This is different from anything Ive ever seen in my 40 years in the automobile industry." ( Detroit Free Press ). 2/12/07 GM is aggressively pursuing plug-in hybrids "because of the tremendous potential to significantly increase fuel economy," according to spokesman Brian Corbett.
Volkswagen says that its MQB strategy represents a turning point in the design and production of its future automobiles with transverse-mounted engines. The advantage is significantly accelerated pressure build-up, which leads to very responsive downsized engines. This, in turn, improves the fuel economy of all MQB-based models.
It was a pitch-perfect strategy for an economy just rebounding from the pandemic, seizing on America’s newfound love for travel, the public’s fascination with Elon Musk and the stock market’s willingness to throw money at anything with an EV story. Hertz started aggressively downsizing in 2024.
federal government has mandated that the country’s government-operated planes, trains, and automobiles run on a fuel blend partly made from corn- and soybean-based biofuels. Environmental Protection Agency (EPA), which stewards the RFS, had repeatedly downsized the targets by nearly 25 percent. For the past decade and a half, the U.S.
Stellantis is reportedly seeking a replacement for Chief Executive Officer Carlos Tavares after the CEO was targeted by the National Dealer Council and United Automobile Workers (UAW). To be fair, most of those brands didn’t seem to have much of a long-term strategy when the automaker was still known as Fiat Chrysler Automobiles (FCA).
