Externalities in North–South technology transfer: the case of CNG engines in Iran
This contribution focuses on illuminating the challenges and difficulties of North–South technology transfer. The central message of this paper is that North–South technology transfer is not simply a contract between two transacting firms and does not depend only on intra–firm and inter–firm factors. The process may also be influenced by a number of external factors, beyond the control or power ...

Case study - Pierce County, Washington: home of the first public transit fleet in the country to run on renewable natural gas
Summary: Li 1986 Pierce Transit was one of the first public transit agencies in the U.S. to trade in its diesel and gasoline-powered buses for buses fueled by compressed natural gas (CNG). 27 years later, this pioneering Agency has just finalized a new contract with the local utility, Puget Sound Energy, to buy an even better fuel: the renewable compressed natural gas (R-CNG). This fuel is ...

How Waste Fleets Can Maximize Fuel Savings While Adopting CNG
Natural gas and, specifically, compressed natural gas (CNG) fueling stations and vehicles running on CNG were all over the industry news in 2012. Organizations such as Republic and Veolia added CNG collection vehicles to their fleet makeup in Pennsylvania, Texas and Wisconsin, while Waste Management opened more than a dozen CNG fueling stations to support its growing fleet of CNG vehicles. While ...

A study on the amount of pilot injection and its effects on rich and lean boundaries of the premixed CNG/air mixture for a CNG/diesel dual-fuel engine
A sequential port injection, lean-burn, fully electronically-controlled compressed natural gas (CNG)/diesel dual-fuel engine has been developed based on a turbo-charged and inter-cooled direct injection (D.I.) diesel engine. During the optimisation of engine overall performance, the effects of pilot diesel and premixed CNG/air mixture equivalence ratio on emissions (CO, HC, NOx, soot), knocking, ...

Natural gas as a promising alternative fuel for passenger cars
The present work (as a field study) investigated the role of compressed natural gas (CNG), as an automotive fuel in CO, HC and CO2 emissions in vehicle exhaust. Besides evaluating the influence of the fuel-feed systems into their cylinders on a vehicular emission level, two different systems were examined; electronic fuel-injection and well-carburetted engines. The chosen vehicles were already in ...

Case study - Grand Junction sets the pace with Colorado’s first biogas-to-vehicle fuel project at the Persigo wastewater plant
In Georgia, renewable compressed natural gas (R-CNG) fuels sanitation vehicles and generates income for DeKalb County. Summary: Designed, built, and operated by the Energy Systems Group, the DeKalb County Renewable Fuels Facility became operational in Apiil 2012. It is die first facility in the US to have a fueling station on-site and generate electricity, renewable natural gas (RNG), and ...

Captive power plant efficiency for Africa
Power distribution networks across Africa are notoriously unreliable. Frequent power interruptions can be enormously costly for many of the continent’s factories. Not only do power outages disrupt production batches, they can also damage or reduce the life of important plant components such as kilns. This too has a knock-on effect on wider the country’s gross domestic product – ...
