KAUST team develops method for reliable prediction of abnormal ignition phenomena

Green Car Congress

Researchers at KAUST’s Clean Combustion Research Center have developed a method to predict and to avoid undesirable combustion events in advanced engines, such as knocking and super-knock. Advanced low-temperature-combustion (LTC) strategies of downsized and boosted engines are capable of offering ultra-low emissions and higher efficiencies.

g/bhp-hr in low load operation using the proposed low load certification cycle being developed at Southwest Research Institute under a contract from the California Air Resources Board (CARB). To achieve our country’s air quality goals, we must ensure trucks are as clean as possible as the heavy-duty fleet moves toward electrification.

These extreme downsizing indicates the potential of a SI, knock-free engine, operating at the same peak pressure as the diesel engine and higher engine speeds. However this aggressive downsizing may not be practical because other constraints (durability, exhaust temperatures). In this manner a 3.6 —Bromberg and Cohn.

California ARB amends diesel rules to reduce cost of compliance

Green Car Congress

The California Air Resources Board (ARB) has amended its diesel rules to offer businesses a variety of options to comply with the regulations to reduce soot from diesel engines. Approved in December 2008, this regulation will clean up emissions from the nearly one million heavy duty diesel trucks that operate in California.

This is also an advantage because cooling systems can be downsized or removed altogether. With Dr. Jorgensen’s in-depth understanding of both automotive and clean energy sectors, we will accelerate the company’s path to become a global market leader in providing ultracapacitors and energy saving modules for the automotive industry.

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

Green Car Congress

The assessment came in an annual report to the Clean Energy Ministerial (CEM). To illustrate this inertia, the report, Tracking Clean Energy Progress , introduced the Energy Sector Carbon Intensity Index (ESCII), which shows how much carbon dioxide is emitted, on average, to provide a given unit of energy.
