A study was conducted to evaluate the effects of various precombustion chamber design, operating, and control parameters on the exhaust emissions of a natural gas engine. Analysis of the results showed that engine-out total hydrocarbons and oxides of nitrogen (NOx) can be reduced, relative to conventional methods, through prechamber design. More specifically, a novel staged prechamber yielded significant reductions in NOx and total hydrocarbon emissions by promoting stable prechamber and main chamber ignition under fuel-lean conditions. Precise fuel control was also critical when balancing low emissions and engine efficiency (i.e., fuel economy). The purpose of this paper is to identify and explain positive and deleterious effects of natural gas prechamber design on exhaust emissions.

A fibre optics combustion intensity detection sensor is developed for the purpose of monitoring and controlling natural gas engines. The sensory system, which is based on the detection of the intensity of the combustion event, is mounted on the top of the engine block. Prior to implementation of the detection system, the accurate kinematics of the sensor probe within the combustion chamber needs to be identified while taking account of the geometric complexity of the engine design. This requires the understanding of the kinematics of probe position within the spatial relations of the engine block geometry that is likely to give a good coverage of the combustion processes. This paper therefore presents a new model that was implemented on natural gas engines but could also be used for identifying the appropriate location within the combustion chamber of any modern engine. An application example using the model is presented. The model provides the ability to monitor completely the stages of combustion within the cycle-to-cycle operation of the engine and use the signal thereof for management and control of the engine. Experience gained from the application of the model resulted in the development of the probe deployment rule discussed in this paper.
