Changes in the attributes (clockwise from upper left, weight, power, fueleconomy and torque) of the Honda Accord over time as an example of fleet trends in the US. In contrast, fueleconomy actually increased by 15% during that period. Tags: Fuel Efficiency. Knittel, 2009. Click to enlarge. Knittel, 2009.
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 fueleconomy 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 fueleconomy improvement to Ford’s passenger vehicle fleet in China by 2015 while reducing tailpipe carbon dioxide emissions by 20%.
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 fueleconomy which featured recently in the Ricardo Centenary celebrations —into volume production on a JAC vehicle.
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.)
Automakers are turning to downsized turbocharged engines to satisfy more stringent global fueleconomy and emission regulations and customer demand for better-performing vehicles. In addition to improving fuel efficiency, downsized turbocharged engines also reduce harmful exhaust emissions.
A 110cc pre-production prototype of a Pinnace Engine 4-stroke opposed piston scooter engine ( earlier post ) showed approximately a 27% improvement in fuel consumption across different scooter cycles compared to a conventional benchmark engine in dynamometer and simulation testing by FEV. 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 fueleconomy (unadjusted) to reach 52 mpg (4.52 Adjusted on-road fueleconomy correspondingly would be 41 mpg (5.74 —A Fuel Efficiency Horizon for US Automobiles.
According to its estimates, adopting the full combination of improved technologies in medium and large cars and pickup trucks with spark-ignition engines could reduce fuel consumption by 29% at an additional cost of $2,200 to the consumer. Turbocharging and downsizing can also yield fuel consumption reductions.
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 fueleconomy 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 fueleconomy requirements.
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 fueleconomy, Eaton says. China’s largest independent automaker, Chery Automobile Co. Tiggo, 1.3S
improvement in fueleconomy 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 industry is a leader in the advancement of technologies in response to performance-based regulations that serve to protect the environment and human health while supporting a diverse range of clean fuel-efficient vehicles that meet the varied needs of consumers.
Also, new-car average fueleconomy 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 fueleconomy 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 fueleconomy improvements.) ( Earlier post.). mpg and 250 g CO 2 /km for model year 2016.
The analysis used by federal agencies to set standards for fueleconomy (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 fueleconomy, don’t care how.
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 fueleconomy 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 fueleconomy," 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 fueleconomy of all MQB-based models.
