Independent on-engine test results have verified the simulation predictions that a Torotrak V-Charge variable drive mechanical supercharger enables more ambitious levels of engine downsizing. The tests were carried out by the University of Bath Powertrain and Vehicle Research Centre (PVRC), using a Ford 1.0L Compared to a current 1.5L
CPT says that the RegEnBoost system enables a typical family-sized car to achieve less than 100 g/km CO 2 with a 1-liter gasoline engine, but when required can offer the same lively performance and in-gear acceleration of a 2-liter naturally aspirated powertrain. The three components of the RegEnBoost system. Click to enlarge.
Their paper was presented at the ASME Internal Combustion Engine Division 2012 Fall Technical Conference by Marcello Canova, assistant professor at OSU; lead author was Philipp Skarke, from the University of Stuttgart Institute for Internal Combustion Engines and Automotive Engineering. Δ in electric range. Power from ORC.
At the recent 2013 SAE World Congress, engineers from Bosch and AVL presented papers on progress in the ACCESS project, describing the design, combustion development and controls development for a resulting 4-cylinder gasoline turbocharged direct injection (GTDI) engine with part-load HCCI capability. Earlier post.). I4 Ecotec engine.
Ricardo will display the first functional integration prototype of the Advanced Diesel Electric Powertrain (ADEPT) collaborative research project ( earlier post ) in public for the first time this week at the Low Carbon Vehicle Event (LCV 2014) in the UK. ADEPT schematic. Click to enlarge.
The pneumatic hybrid engine, which follows the downsizing and supercharging paradigm, offers a fuel-saving potential that is almost equal to that of hybrid electric powertrains while inducing much lower additional mass and cost penalties, according to the ETH Zürich researchers. The compressed air supply also allows extreme downsizing.
Projects to be funded include: Ultra Lightweight Gas Turbine Range Extender for Electric Vehicles. The aim of this project is to develop an ultra-lightweight, gas turbine powered, electric vehicle range extender that will enable vehicle weight savings of 100 kg or more and a modest reduction in CO 2 emissions on the UNECE101 drive cycle.
GDCI engine was significantly better than advanced production spark injection gasoline engines, and comparable to very efficient hybrid vehicle engines at their best efficiency conditions (214 g/kWh). This early work established that gasoline-like fuels with high resistance to autoignition are preferred for PPCI. Earlier post.)
Ford’s approach to the project was to engineer a comprehensive suite of gasoline engine systems technologies, including: Aggressive engine downsizing in a mid-sized sedan from a large V-6 to a small I-4. 1, and the engine is designed to run on 98 RON gasoline. Electric TiVCT system. Earlier post.). The approach.
Relative changes in vehicle energy efficiency (VEE) (km/MJ) on ethanol/gasoline blends over those on gasoline for different blending levels. Several recent highly cited LCAs that have incorporated vehicle efficiency differences between gasoline and ethanol/gasoline blends could potentially be misleading. Click to enlarge.
The Ricardo-led Advanced Diesel Electric Powertrain (ADEPT) project will apply 48V “intelligent electrification” concepts, mild hybridization and waste heat recovery in a Ford Focus diesel demonstrator. In 2011, the HyBoost team reported that the HyBoost demonstrator was achieving comparable performance to the conventional 2.0L
Augmenting its existing LC Super Hybrid program ( earlier post ), which deploys a downsizedgasoline-electric powertrain, ALABC is working on advanced diesel-electric applications in development programs being undertaken with car makers including Ford and Kia. These compact electrical machines can be rated up to 12.5
Comparison of fuel consumption of Omnivore, homogeneous Gasoline Direct Injection (GDI) and Spray-Guided GDI engines. The first testing phase of Lotus Engineering’s Omnivore variable compression ratio, flex-fuel direct injection two-stroke engine ( earlier post ) has been successfully completed on gasoline.

At the 2 nd International Conference Automotive 48 V Power Supply Systems , held last week in Düsseldorf, Germany, Controlled Power Technologies (CPT), a major sponsor of the event, together with leading car makers and Tier 1 suppliers, argued the need for an internationally agreed 48V electrical standard.
The Vehicle Technologies Office Program Wide Selections will aim to reduce the cost and improve the efficiency of plug-in electric, alternative fuel, and conventional vehicles through thirty-five projects addressing 11 areas of interest. Grid Modernization for Electric Vehicles (Area of Interest 2). Description. Federal funding.
In recent years two methods, namely downsizing and downspeeding, were established on the market to reduce CO 2 emissions while maintaining the driving performance of engines with identical effective power but a larger displacement. In the project, the base 4-cylinder SI engine was replaced by a turbocharged 1.0-liter, to 11.5.
In a new survey of 674 vehicle owners across the country, Brandon Schoettle and Dr. Michael Sivak of the University of Michigan Transportation Research Institute (UMTRI) examined several topics related to fuel economy and advanced vehicle technologies. Gasoline internal-combustion engines rated second-most preferred at $2.50/gallon,
Electric supercharging provides a cost-effective technology for controlling emissions without increasing fuel consumption. The electric supercharger technology developed by CPT is not driven by conventional electric motors, but by switched reluctance machines controlled with high precision using advanced electronics and software.
GM has announced plans for public sales in 2010, and almost every carmaker now says it will sell PHEVs or highway-speed battery electric vehicles (BEVs) sometime after 2010. Shifted earlier focus to all-electric Focus in 2011 with Magna. Company says its focusing on gasoline and hydrogen. todays answer is "Yes -- but not yet."
The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. (In In this paper PHEV refers solely to the long-range PHEV of 60 miles (100 km) electric-only range.) It is much more than that.
