Navigant forecasts global road transportation energy consumption to increase 25% by 2035; 84% from conventional fuels

Green Car Congress

Navigant also projects that investments in alternative fuel and fuel efficiency improvements will reduce annual energy consumption in the United States year-over-year. The alternative fuels market share will grow from roughly 7.4% quadrillion Btu projected to be consumed in 2014.

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

Green Car Congress

Mahle has developed a new thermal spray coating for modern high-output direct-injection turbocharged gasoline engines (GTDI). Under development since 2011 at Mahle’s thermal spray development labs in Michigan, the new process initially was designed for high-output GTDI engines currently in production by two US domestic automakers.

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

Green Car Congress

In one paper, published in the journal Fuel , they investigated the use of alcohols–gasoline DFSI Combustion for knock suppression and high fuel efficiency using a gasoline engine with high compression ratio. Alternatively, in the second study, gasoline–alcohol DFSI is based on PFI of gasoline and DI of alcohols.).

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

Green Car Congress

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.

This is also an advantage because cooling systems can be downsized or removed altogether. in Chemical Engineering at Stanford University in 1985. This factor is crucial as it greatly increases the efficiency of the cells by reducing the amount of energy that is lost as heat.

Split injection Miller cycle with boost decreases knock tendency and increases torque in downsized engine

Green Car Congress

Researchers at Tianjin University in China report that combing split injection to the Miller cycle with boost pressure can effectively decrease the knock tendency and increase the engine torque in a downsized spark-ignition engine. Their paper is published in the journal Fuel. —Wei et al. —Wei et al.
