Tsinghua studies on alcohol-gasoline dual fuel engines show fuel efficiency and particle number benefits

Green Car Congress

AUGUST 10, 2015

Researchers at Tsinghua University in China are studying the effects of Dual-Fuel Spark Ignition (DFSI) combustion fueled with different alcohols and gasoline. Alternatively, in the second study, gasoline–alcohol DFSI is based on PFI of gasoline and DI of alcohols.). —Liu et al. —Liu et al.

Navigant also projects that investments in alternative fuel and fuel efficiency improvements will reduce annual energy consumption in the United States year-over-year. Conventional fuels (e.g., gasoline and diesel) represent the bulk of energy consumption throughout the forecast period. Click to enlarge.

FEV’s two-stage VCR system; 5-7% increase in fuel economy using variable length conrods

Green Car Congress

APRIL 22, 2013

Use of a variable compression ratio (VCR) could be one technology approach to reducing fuel consumption in highly boosted (e.g., 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.

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.

New Mahle piston ring coating for high-output GTDI engines; chromium nitride using high-velocity oxygen fuel process

Green Car Congress

SEPTEMBER 16, 2015

Mahle has developed a new thermal spray coating for modern high-output direct-injection turbocharged gasoline engines (GTDI). The new coating also was developed to help meet requirements for new production engines planned for 2018-2020, which call for less cylinder-bore friction and the use of lower-viscosity oils and alternative fuels.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

JULY 17, 2015

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. 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. It is much more than that.
