Rare Rides Icons: The Cadillac Eldorado, Distinctly Luxurious (Part LXII)

The Truth About Cars

The model lasted two additional years after the rest of the Cadillac lineup was downsized for 1977, as GM prepared to modernize the E-body platform that dated to 1966. Emissions regulations increasingly demanded engines spew a lower volume of toxic chemicals from their exhausts. By 1979, the U.S. The consumer base was also changing.

Use of Supercritical Diesel Fuel for Improved Efficiency and Reduced Emissions

Green Car Congress

Heat required to bring the fuel to SC states is recovered from the exhaust gas of the engine. To attenuate that risk, the researchers use a diluent such as CO 2 , H 2 O or exhaust gas. George Anitescu from Syracuse presented the work in a poster at the DEER 2009 conference in Dearbon, Michigan. At SC conditions, however (T?450

Lotus Omnivore Engine Shows Up To 10% Better Fuel Economy Than Spray-Guided GDI Engines; Achieves HCCI At Extremely Light Loads

Green Car Congress

The automotive industry, including Lotus Engineering, has quite rightly advocated engine downsizing for four-stroke engines. Downsizing therefore isn’t vital and, due to the improved light-load efficiency and emissions performance we see with Omnivore, this technology approach and ‘upsizing’ could permit a more efficient engine.
