Renault Trucks’ Optifuel Lab 2 lab vehicle integrates technologies for more efficient big rigs; road test results coming in 2015

Green Car Congress

These figures will be announced during the first quarter of 2015. The idea is to take as little energy as possible from the internal combustion engine. We therefore electrically powered several of the vehicle’s auxiliary items of equipment such as the air-conditioning, water pump, fuel pump and the steering pump.

LiquidPiston unveils 70cc rotary gasoline engine prototype embodying HEHC; power dense, low-vibration

Green Car Congress

HEHC is an improved thermodynamic cycle optimized for fuel efficiency that combines features of four existing cycles: high compression ratio (Diesel); constant volume (isochoric) combustion (Otto); over-expansion to atmospheric pressure (Atkinson); and internal cooling with air or water (Rankine). Shkolnik, A., Littera, D., Nickerson, M.,

Behind Audi’s new “rightsized” efficient EA888 Gen.3B family

Green Car Congress

Highlights of the Gen2 TFSI were the Audi exhaust valve lift system and a pressure- and volume-flow-controlled oil pump. 3B idea is to combine a shortened compression with a normal—i.e., mm, and moved the intake and exhaust valves—slightly reduced in diameter—axially downward. Audi says that the new 2.0L

First look at all-new Voltec propulsion system for 2G Volt; “the only thing in common is a shipping cap”

Green Car Congress

The power electronics and the motors use separate cooling: water for the PE and ol for the motor unit. 1, cooled exhaust gas recirculation and a variable displacement oil pump. We had the idea in first gen that we would have a full-size battery and a half-size engine. Click to enlarge.

Climate Expert: Don't Call It Geoengineering

Cars That Think

Everyone solemnly agreed, again, to follow the science, which has shown in exhaustive detail that humanity will suffer from heat, fire, floods, and droughts if the world warms beyond 1.5° In 2015, the U.S. C above pre-industrial levels. Yet if countries continue on their present course, the world will likely have warmed by 2.7°

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

For offsets to be credible, a ton of CO 2 -equivalent emissions from an offset project should equate to a ton reduced from a covered emission source, such as a smokestack or exhaust pipe. To be credible, as noted above, an offset should equate to an emission reduction from a direct emission source, such as a smokestack or exhaust pipe.

What are Fuel Cell Electric Vehicles? Will They Replace BEVs?

Get Electric Vehicle

Like BEVs, FCEVs’ exhaust produces no smog-forming or climate-changing emissions; the sole result is water. There is currently no hydrogen fuel station in India but countries such as Japan, China, the United States of America, Korea on the other hand, have begun to embrace the idea of a hydrogen-based society.
