This work presents a methodology to adjust the electronic control system of a reciprocating internal combustion engine test bench and the effect of the control parameters on emissions produced by the engine under two extreme situations: unadjusted and adjusted, both under transient operation. The aim is to provide a tuning guide to those in charge of this equipment not needed to be experts in c...

in this literature, a combined method has been employed to simultaneously reducesmoke (soot) and oxide of nitrogen (nox) and maintain the performance parameters of dieselengine. this includes creating an air jet by designing an air-cell inside the piston body, advancedinjection timing and using cold exhaust gas recirculation. the tested engine was an mt4.244engine that worked as natural aspirat...

homogenous charge compression ignition (hcci) is a mode of combustion in ic engines in which premixed fuel and air are ignited spontaneously. there is a belief that hcci engines have a great potential to improve fuel consumption and reduce nox emissions. in this study, a single zone, zero dimensional, thermo-kinetic model has been developed and a computer program with matlab software is used to...

using instrumented tractors to monitor and record spatial variations in performance parameters of tractor and implements during field operations, could improve productivity and the tractor efficiency. in the context of precision farming, this information can be used to map spatial variability of the parameters and to find the relations with changes in soil attributes (texture, moisture contents...

Various research groups across the globe have developed models for engine condition monitoring and fault diagnosis based on the data from steady state performance measurements over the last two decade. However, these performance data are not amenable for easy collection in some situations and some of the data may show little performance deviation at the steady state conditions of operation. In ...

in this study the performance and emissions characteristics of a heavy-duty, direct injection, compression ignition (ci) engine which is specialized in agriculture, have been investigated experimentally. for this aim, the influence of injection timing, load, engine speed on power, brake specific fuel consumption (bsfc), peak pressure (pp), nitrogen oxides (nox), carbon dioxide (co2), carbon mon...
