The Swiss limit for NOx exhaust gas emissions from decentralised electrical power and heat cogeneration units using stationary I.C. engines operating on natural gas, despite a recent increase from 80 to 250 mg/mN3 (5% O2), remains the most severe in force ...
Nowadays, most of the natural gas conversion systems available on the market for bifuel vehicles are based on the venturi principle or on the continuous injection principle for the carburation of the engine. Even if the driveability of these systems is sat ...
Tests were undertaken with a Renault Express 1.4 litre converted to natural gas operation. The effect of cold starts at cold temperatures and vehicle weight on tail pipe emissions were investigated with petrol and natural gas operation over the FTP75 and t ...
In Switzerland there is a significant interest to use natural gas as a vehicle fuel. This interest stems from both a desire to reduce the environmental pollution caused by automobiles and a wish to diversify the sources of energy supply. The current “state ...
Ausgehend von der im Abschlussbericht des OMEGAZ Projektes geschilderten Arbeit wurde eine umfassende Testreihe mit verschiedenen Fahrzyklen durchgefuehrt, um die tatsaechlichen Emissionen von mit Erdgas betriebenen Fahrzeugen mit den von benzinbetriebenen ...
A medium size diesel engine converted to natural gas operation on the Otto principle has been studied under stoichiometric and lean burn operation in order to evaluate the potential to reduce the NOX exhaust gas emissions below the stringent limit prescrib ...
Test were undertaken with a Renault Express 1.4 litre converted to natural gas operation. The effect of cold starts at cold temperatures and vehicle weight on taile pipe emissions were investigated with petrol and natural gas operation over the FTP75 and 9 ...
The title of this paper, “Against the Odds - Switzerland and the Emergence of NGV’s”, written some time ago reflects an expectation based on test results and considerable market interest. Unfortunately at the time of writing Switzerland is still awaiting t ...
In the frame of the decentralised electrical power and heat cogeneration with stationary I. C. engines operating on natural gas, the Swiss limit for exhaust gas emissions, with 80 mg/mN3 (5% O2), is the most severe in force on an international level. On th ...
