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. —David Boggs. Micro-hybrid market. million units per year by 2020.
Cost of the new engine relative to gasoline baseline. 2013) “Cold Start Concept (CSC): A Novel Catalyst for Cold Start Emission Control,” SAE Int. l/100 km), and as such would not meet the GHG requirement of 28 mpg (8.4 l/100 km) for a vehicle of that size.

Christopher Thomas, BorgWarner VP, Advanced Engineering, Engine Group and VP, Advanced Engineering, Drivetrain Group presented the basic concepts of VEMB and current BorgWarner test results at the recent SAE 2012 High Efficiency IC Engine Symposium. Total cost of implementation is much less than $10/1%, he said. and Sisson, J.
Comparison of Fuel Consumption, Fun to Drive and System Cost of the different powertrain concepts. However, the system cost of the Turbohybrid was 150% that of the baseline, while the system cost of the full hybrid was more than 300% that of the baseline. Stage 1 of the Turbohybrid powertrain concept.
liter ELC-Hybrid to downsized 1.4L VTES + SpeedStart. CPT and AVL’s most recent work assesses the potential of a VTES equipped downsized ELC-Hybrid vehicle in combination with the CPT SpeedStart Integrated Starter Generator ( earlier post ) and the UltraBattery. Click to enlarge. —Guy Morris.
Zeroshift’s multi-speed transmission concept changes gear without interrupting the torque, allowing EVs to run for longer at peak efficiency. Development of the concept is underway using Zeroshift’s proprietary gear-shifting system. The improved efficiency offered by Zeroshift’s concept could also extend EVs’ in-service battery life.
Showcased at the Consumer Electronics Show in January in Las Vegas ( earlier post ), the FCV Concept, which presages the introduction of the series-production vehicle, made its European debut at the 2014 Geneva Motor Show. The output power is more than 100kW, despite significant unit downsizing. Toyota’s view of hydrogen.
At 48 volts, a VTES electric supercharger will transform 7kW of battery power into a highly boosted charge of air for downsized gasoline and diesel engines. There will be no torque deficit or other tradeoffs from essential engine downsizing and higher gearing, which now dominates the development of internal combustion engines.
The investment will be made in sixteen proof of concept studies, which will last up to one year, and six longer-running full research and development projects. The small size, multi-fuel capability and potential low cost of the ULRE could also help speed adoption of electric vehicles. Ricardo UK Ltd (lead), Lontra, Ford Motor Company.
liter EA888 Gen3 engine featured in Audi’s all-road shooting brake plug-in hybrid concept unveiled at the North American International Auto Show this week ( earlier post ) features—as does its production ilk—a dual injection system that combines direct injection with indirect injection into the intake manifold.

downsized, turbocharged) gasoline engine, as operating an engine with higher compression ratios at low load can increase fuel economy compared to operating an engine with fixed compression ratio. There have been a number of concepts proposed to enable such VCR systems. Working principle of FEV’s two-stage VCR system. Click to enlarge.
ADEPT combines the two technologies, which have been demonstrated individually but not yet as an integrated system, applying the low voltage concept of ‘intelligent electrification’ for the first time to a diesel car. SR machines are ideally suited to this concept of low cost development, while reducing the cost of production components.
The T-Hybrid (based on a Kia Optima) ( earlier post ) and the ADEPT (based on a Ford Focus) ( earlier post ) both utilize an advanced 48V lead-carbon battery system with bolt-on electrical components that allow for significant engine-downsizing without loss in performance. This concept vehicle is powered by the Optima’s existing 1.7
Among the findings were: 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. For example, the report notes the promise of cylinder deactivation, turbocharging and downsizing.
As part of this downsizing trend, thermal coatings are increasingly replacing grey cast iron cylinder liners in engine blocks. The purchase cost of a pump delivering 600 bar is substantially lower than that of a 3000 bar unit. At the same time, its filtration system can be of less complex design.
million grant to develop and to demonstrate a new ultra fuel efficient vehicle (UFEV) vehicle concept. Delphi has been developing a multi-cylinder engine concept for PPCI combustion with the current US market gasoline (RON91).… Earlier post.) DOE UFEV program targets. Vehicle fuel efficiency on FTP. +35% 35% (PFI baseline).
The selected projects will focus on reducing the total cost of ownership of NGVs, increasing vehicle efficiency, decreasing local air pollution, and advancing technology development to increase the use of more affordable medium- and heavy-duty natural gas engines and vehicles. CNG Full Fills with a Complete Smart Fueling System.
Future RDE emissions legislation and fleet average CO 2 targets represent a challenge for automakers wishing to provide cost-effective light duty diesel vehicles. At the SIA conference, Ricardo also exhibiting a the ADEPT concept vehicle, combining low-cost 48V, mild-hybrid technologies with the aim of reducing 1.5L
As the limit in downsizing metal morphology, the concept of single-atom catalysts (SACs) has emerged since it maximizes the exposed atom efficiency. Ruthenium is often a highly active catalyst when fixed between arrays of four nitrogen atoms, yet it is one-tenth the cost of traditional platinum. —Zhang et al.
The mass reduction for this nearer term vehicle, excluding powertrain, is 21% with an estimated cost saving of 2%. In developing the two low-mass concepts, Lotus Engineering employed a total vehicle mass-reduction strategy utilizing efficient design, component integration, materials selection, manufacturing and assembly.
First revealed as a concept in 2021 , Volvo CE’s CX01 autonomous “single drum” asphalt roller concept has seen continuous development in the years since. TARA enables you to downsize and replace larger diesel-powered vehicles with a fleet of autonomous electric Volvo TA15s capable of running 24/7,” reads the official TARA release.
Audi Volkswagen-owned company exploring PHEVs Metroproject Quattro Sub-compact PHEV Concept Car shown October 2007; PHEV of A1 Sportback under consideration Bright Automotive For-profit spin off from Rocky Mountain Institute designing lightweight PHEVs, successor to RMIs 1990s "Hypercar" concept. Has shown some concept fuel-cell PHEVs.
Another strikingly different concept evidenced by the PHEV is that it is essentially a large, portable battery that can store energy gathered during one part of the day, and then use it later to power not only itself but also the vehicle owner’s home. per gallon, that would cost $1200, adding up over 20 years to $24,000.
While the use of conventional diesel and gasoline pose several challenges for this approach, the Eindhoven researchers observed, other fuels in the gasoline boiling range have been shown to very suitable for the concept. The load range over which the concept can be applied depends on the reactivity of the fuel. —Chang et al.
