Mazdas new SKYACTIV gasoline and diesel engines are steps on the road to its Ideal Engine; focus on compression ratio

Green Car Congress

However, while Mazda plans to offer hybrid vehicles in the medium-term, its engineers are pushing hard to increase the efficiencies of both the gasoline and diesel platforms, moving toward what they call “the ideal Internal Combustion Engine.” Extreme compression ratio rather than downsizing. Although downsizing—i.e.,

Study finds highly-turbocharged alcohol-fueled DISI engines could be more efficient than diesels

Green Car Congress

Alcohol-based transportation fuels from a wide range of biomass feedstocks including agricultural, forestry, municipal and industrial waste and specially grown crops and trees can potentially offer a substantial substitute for oil derived fuel. More modest downsizing up to 5 liters could offer a practical solution. In this manner a 3.6

DENSO Develops Exhaust Gas Temperature Sensor With Improved Temperature Detection Accuracy

Green Car Congress

With the improved temperature detection performance, the new sensor helps regenerate DPFs more efficiently, resulting in cleaner emissions, as well as increased fuel efficiency due to less fuel required in the DPF regeneration process.

IEA: carbon intensity of global energy supply has barely changed in last 20 years; “window of opportunity in transport”

Green Car Congress

The global energy supply became 6% cleaner from 1971 to 1990,in response to the oil shocks of the 1970s. The world must slow the growth of energy demand as well as make its energy supply cleaner, the IEA said. The world must slow the growth of energy demand while making the energy supply cleaner. tCO 2 /TJ (2.39

Daihatsu develops e:S Technology for 30 km/l in JC08 Mode; equivalent to 71 mpg US or 3.3 L/100km

Green Car Congress

The company anticipates that it will be the only gasoline-powered vehicle delivering fuel economy of 30 kilometers per liter (equivalent to 71 mpg US or 3.3 and the downsizing of the particles sprayed from the injector. L/100km) in JC08 mode. This new mini vehicle will have an entry price of less than ¥800,000 (US$10,200).

Use of Supercritical Diesel Fuel for Improved Efficiency and Reduced Emissions

Green Car Congress

Given the high reactivity of diesel fuels compared to gasoline, the ignition and combustion of pre-mixed fuel-air charges poses a challenging control problem. The technology is optimized with modern high compression diesel architecture engines, near-term running on gasoline while longer-term utilizing advanced low carbon footprint bio-fuels.

They use cheap, clean, and domestic electricity for short trips and daily commutes, displacing or eliminating oil consumption and CO2 pollution. What changes do we make to convert a gasoline-only hybrid to a Plug-In Hybrid? Electric Vehicles not only keep our Earth cleaner, their use preserves the earths natural resources.
