Study Finds Strong Synergy Between Spark Ignition Engine Downsizing and Low-to-Moderate Alcohol Blend Fuels

Green Car Congress

MAY 1, 2009

A study by engineers from Mahle Powertrain Ltd and BP found strong synergy between spark ignition (SI) engine downsizing and fuel containing low-to-moderate amounts of alcohol, including ethanol and butanol. A Study of Gasoline-Alcohol Blended Fuels in an Advanced Turbocharged DISI Engine. ( Cairns et al. Cairns et al.

The resulting higher BMEP levels allow downsizing of the engine at equivalent vehicle performance. EBS has a collaborative R&D agreement with Ford, and participated in the study reported at the World Congress. In the study, Ford applied the E85 boosting approach to two engines: an early prototype 3.5-liter Earlier post.)

JUNE 4, 2010

Using a 2007 base vehicle, the committee estimated the potential fuel savings and costs to consumers of available technology combinations for three types of engines over that timeframe: spark-ignition gasoline, compression-ignition (CI) diesel, and hybrid. The practicality of full-performance battery electric vehicles (i.e.,

As a point of comparison, the US EPA’s proposed national CO 2 emissions standards for light-duty vehicles under section 202 (a) of the Clean Air Act would require these vehicles to meet an estimated combined average emissions level of 250 grams/mile of CO 2 —155.26 In 2014, any weight increase in new cars will be studied.

ETH Zürich Developing Pneumatic Hybrid Engine; Approaches Hybrid-Electric Performance at Lower Cost

Green Car Congress

FEBRUARY 1, 2009

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.

From a “well-to-wheel” perspective, high efficient gasoline and diesel engines are nearly as energy efficient as any technology available. The quickest and most cost-effective way to achieve our energy usage goals is through faster adoption of fuel-efficient downsized gasoline and diesel engines. They determined that only 3.9

Engine downsizing and downspeeding are two strategies that can be applied to gasoline and diesel engines to improve vehicle fuel economy. In the study described in the paper—which was a continuation of previous work on pursuing fuel economy improvements via downspeeding—the team used a turbocharged 2.0L

Though the PHEV combines the two types of energy and power, it is not merely a temporary “transition” between gasoline and diesel cars to pure electric cars. Since it can refuel from a standard household outlet and from a gasoline station, it needs no new infrastructure. It is much more than that. Conclusions. slow charge.
