System identification of a natural gas engine
Proceedings of the 1998 American Control Conference. ACC (IEEE Cat. No.98CH36207), 1998Simulation results are shown for linear system identification carried out to identify key model parameters of a lean-burn natural gas engine with transmission. The natural gas engine can be described by a nonlinear plant with three states. The dynamic state equations of the model involve parameters that might vary depending on ambient conditions, type ...

Highly Efficient Natural Gas Engines
SAE Technical Paper Series, 2017<div class="section abstract"><div class="htmlview paragraph">The 2020+ CO<sub>2</sub> and regulated noxious emission limits will impose drastic technological choices. Even though in 2030 65% of road transportation vehicles will be still powered by internal combustion engines, a progressive increase of hybrids and battery ...

The Public Utility and the Natural Gas Engine
SAE Technical Paper Series, 1964<div class="htmlview paragraph">The natural gas engine is a superb method of gas utilization from the aspect of load factor improvement on gas utility company lines. The importance of fuel economy on long running units is shown to be the major component in the cost of generating mechanical energy.

Operation of gasoline engines on natural gas
2014The Association of European Vehicle Manufacturers (ACEA) has undertaken a commitment to reduce average CO2 emissions to 140 g/km by the year 2008. This represents a reduction of 25% when set against the figures recorded back in 1995. Vehicle concepts based on CNG (Compressed Natural Gas) contribute to lowering CO2 emissions.

Controlling emissions of natural gas engines
Proceedings of the Air and Waste Management Association's Annual Conference and Exhibition, 2017Different selective catalytic reduction (SCR) and oxidation catalyst systems were assessed to study the effects of these catalysts on the NO x, the hydrocarbon and the particle emissions from natural gas engines. High NO x reductions were observed at low ammonia slips. A separate oxidation catalyst was used downstream of the SCR.
