Effect of injection parameters and emissioncharacteristics in a common-rail direct injection diesel engine in height conditions: A review

Abstract:

The common-rail direct fuel injection (CRDI), it is currently employed in diesel engines. The objective of this study is analyzing the combined effects of injection pressure and emission of a diesel engine with CRDI fueled with biodiesel in height conditions, for which an exploratory-explanatory investigation is carried out about the main works carried out in relation to this topic, applying the PRISMA methodology. A comparative analysis of emissions between diesel and biodiesel and the effect that height has on emissions is carried out It is concluded that pollutants such as particulate material, carbon monoxide and hydrocarbons are reduced three times less with the use of biodiesel, nevertheless, the value for nitrogen oxide tends to increase drastically up to 5 times more with the use of biodiesel, whereby biodiesel is a fuel alternative to reduce emissions without sacrificing significantly power factors and engines performance. In relation to the design, it is determined that the number of holes, the number of flat springs and the injection pressure are the three factors that have the most influence on the performance of the engine.
