Potential Use of LPG in A Medium Capacity Stationary HCCI Engine
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2015, Vol 5, Issue 2
Abstract
Internal combustion engines are extensively used in every field of life in today’s world. Diesel engines being more efficient are preferred in the industrial and transportation sector in comparison to spark ignition engines for their higher efficiency, versatility and ruggedness. The major emissions of diesel engines are oxides of nitrogen (NOx), particulate matter (PM), carbon dioxide (CO2), carbon monoxide (CO). Among these emissions, oxides of nitrogen (NOx) and the particulate matter are the reasons of serious concern. For reduction of oxides of nitrogen (NOx) and particulate matter simultaneously, the use of Homogeneous Charge Compression Ignition (HCCI) have provided a sustainable solution in the present scenario. This paper presents the findings of an experimental investigation into the operation of a compression ignition (CI) engine in homogeneous charge compression ignition (HCCI) mode using LPG as the main fuel and diesel as pilot injection. Factors that were investigated include engine performance and emission characteristics and based on the results, LPG was found to be a possible fuel for operation of a CI engine in HCCI mode. A methodology using a small pilot quantity of diesel fuel injected during the compression stroke to improve the power density and operation control is carried out for an HCCI engine based on a stationary, constant RPM, water cooled diesel engine. The objective of this study is to investigate the performance and emission characteristics of HCCI engine fuelled with LPG and help understand the viability of LPG as an alternative fuel in diesel engines for use in the automotive industry
