Study finds “markedly” high levels of diesel exhaust present in commuter trains powered by locomotives in pull-mode

Green Car Congress

However, both measurements also act as proxies for the complex mixture of gases in diesel exhaust, which is an established carcinogen and associated with respiratory, cardiovascular and reproductive health effects. They also took measurements while walking along busy streets in downtown Toronto for comparison.

FEV testing finds Transient Plasma ignition system increases fuel efficiency and decreases emissions

Green Car Congress

Data was collected with the stock ignition system with a representative ignition strategy, followed by comparison to a drop-in replacement with the TPS nanosecond pulsed power ignition system (coil and plug). The Toyota 2.5L engine was tested at FEV North America and results indicate improvements over the stock ignition system.

ICL briefing paper estimates that 52% of all small particle pollution from road transport comes from tires and brakes

Green Car Congress

Despite this, research on the environmental and health impacts of tire wear has been neglected in comparison to the research and innovations dedicated to tackling fuel emissions. Six million tonnes of tire wear particles (TWP) are released globally each year, and in London alone, 2.6

Audi testing find e-ethanol and e-diesel produced by Joule often perform better than conventional counterparts

Green Car Congress

During each of up to 3,000 revolutions per minute in the research engine, a minute amount of fuel shoots into the glass cylinder, is compressed and ignited, and the exhaust gas then expelled. As a result, the synthetic fuels assure a more effective mixture preparation process, cleaner combustion and lower emissions.

Study finds biodiesel use in HD trucks in Canada will result in very minimal changes in air quality and health benefits

Green Car Congress

However, the impact of these changes in HDDV exhaust emissions on ambient atmospheric pollutant concentrations and, more importantly, on human health outcomes across Canada have not been evaluated. exhaust emission control devices and vehicle efficiency) outweigh changes in emissions associated with the use of blends lower than B20.

New Icon-class ships from Royal Caribbean to be powered by LNG with 2022 delivery; testing hydrogen fuel cells in 2017

Green Car Congress

Royal Caribbean is making progress on energy efficiency and reduced emissions through such technologies as air lubrication, which sends billions of microscopic bubbles along the hull of a ship to reduce friction, and advanced emissions purification (AEP) scrubbers, which clean exhaust gases before they leave the ship.

Comparison of brake thermal efficiency and specific fuel consumption at rated power (ICOMIA Mode 5), hydrogen vs. gasoline engines. This is due to raw, externally premixed fresh charge comprising air, fuel and lube oil being short-circuited into the exhaust during the scavenging process. Oh and Plante. Click to enlarge.
