Given the properties of the fuel blend, improved fuel efficiencies can be generated by several approaches, including downsizing/downspeeding; increased compression ratio; reduced enrichment; and the leveraging of improved efficiency at part load.
This is to be achieved through the synergistic application of an extremely downsized gasoline engine coupled with electrified boosting and exhaust gas energy recovery; micro-hybrid functionality with stop/start, torque assist and regenerative braking; and a novel energy storage technology. The vehicle is to offer the performance of a 2.0
The combustion of 1 liter of diesel fuel produces approximately 11% more energy than gasoline fuel, but the diesel fuel also releases approximately 11% more CO2 due to its higher carbon content. On top of the higher energy density of diesel fuel, diesel engines historically possessed a number of efficiency advantages over gasoline engines.
This first report (Phase I) examines only the impact of improving the efficiency of fossil-fueled vehicles, in which efficiency gains are delivered by the improvement of the internal combustion engine vehicle, including lightweighting, engine downsizing and hybridization.
Mercedes highlights the most important measures as including: For all gasoline and diesel drive systems: Friction-optimized downsizing engines with turbocharging, direct injection and thermal management; gasoline engine with Camtronic (C 180). The start/stop system as standard for all engine variants.
liter gasoline, downsized 2.0-liter The most substantial improvement was seen on the downsized, turbocharged gasoline engine, an architecture that is predicted to be one of the most important as the industry moves to smaller, more highly-stressed spark-ignition engines with or without electrification. liter gasoline with GDi, and 2.0-liter
A second new downsized engine for the Sportage is the 135 ps (133 hp, 99 kW), 1.6-liter As it will be applied in the production Sportage, the new 1.7-liter liter diesel is fitted with a variable geometry turbocharger and generates 115 ps at 4,000 rpm, with 255 N·m (188 lb-ft) of torque from 1,800 rpm for responsive driveability. (A
Downsizing, gasoline direct injection (GDI), and start-stop will be the key technologies helping original equipment manufacturers (OEMs) achieve emission targets by 2015. ACEA says that the industry spends €20 billion (US$28.8 By 2015, the average car in Europe will be 5 per cent lighter, with 30 per cent lower CO 2 emissions.
As part of the new plan, Valeo will devote two-thirds of its advanced research investment to developing technology solutions for downsized internal combustion engines and for hybrid and electric vehicles. Another key focus point is reduced component weight and energy consumption. billion) in 2020 (more than one-third of total sales).
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. liter engine the performance of a 1.8
The industry has long recognized that increasing injection pressure to 500+ bar could substantially cut engine-out particulates while improving CO2 emissions and fuel economy. —Walter Piock, chief engineer, Gasoline Systems, Delphi Technologies. Delphi 500+ bar GDi injector. —Walter Piock.
Within advanced ICE technologies, engine downsizing, turbocharging, optimized cooling, low friction, start-stop systems, electric power steering, direct injection, and variable valve timing will likely lead. Conventional technologies with high CO 2 reduction potential. Source: BCG. Click to enlarge. ICE-propelled vehicles.
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.
It is important that the European Commission not only set new car CO2 targets for 2025 and 2030 but also limit the gap between laboratory and real-world levels by defining an on-road conformity factor for CO2, as it has already done for air pollutants.
Renault’s ongoing downsizing strategy is aimed at reducing the cubic capacity of its engines in order to bring down fuel consumption and CO 2 emissions, without detracting from performance. The downsizing process involved shortening the piston stroke by reducing the size of the crank pin and conrod assembly. Select Engines.
Our customers are downsizing their engines to meet stringent CO2 requirements. Delphi says that the common rail system will suit future generations of downsized engines in a range of vehicle classes. This combination allows for just 87 g/km of CO 2 emissions.

With this type of engine, reaching the target of 120 g of CO2/km seems realistic by 2012-2013 for high-performance vehicles, with a strong reduction in fuel consumption for the whole vehicle range, MCE-5 suggests. This constitutes a strong response to the durability problem of highly downsized high-loaded engines.
A bridging option is to use methanol derived from natural gas, with a CO2 intensity that is no worse than conventional fuels. There is also the possibility of achieving greenhouse gas reduction by CO2 sequestration in the methanol generation process.
The first element of a long-term fuel strategy should be ongoing efforts to increase the energy efficiency of all transport operations as well as vehicles, through implementation of such options as downsizing, direct injection, charging and engine displacement reduction and the utilization of new efficient combustion systems.
At the 2009 SAE World Congress, a Ford study revealed that a separate E85 direct injection boosting system combined with a petroleum port fuel injection makes an engine more efficient in its use of petroleum - and can be viewed as a more cost effective alternative to diesel.
Before we were saying it will be an awfully long time before we can get the costs down so people can afford it, but actually if you offset the fuel costs, people can afford it." ( Green Car Congress ). The resulting fuel efficiency improvements mean lower CO2 emissions and less fossil fuel consumption and, therefore, less pollution.
