Abstract
Increasingly stringent limits on CO2 emissions and toxic exhaust components are a challenge for the automotive industry as well as for research centres working in this area. A number of measures are in place to reduce the above-mentioned compounds in internal combustion engines, e.g. optimisation of the combustion process to achieve lower emissions, use of external exhaust aftertreatment systems, application of advanced combustion systems and use of biofuels with a low carbon footprint. Hydrotreated oils (HVO) are one such type of biofuel, produced mainly by hydrotreating vegetable oils. HVO can be produced from waste raw materials from the food industry, so that we can then classify it as a 2nd generation renewable fuel. The use of HVO produced from 100% renewable raw materials can result in up to 90% fewer greenhouse gas emissions (GHG or CO2e) over the entire life cycle of the fuel compared to fossil diesel. Similar properties to diesel allow the use of hydrotreated oils in compression-ignition (SI) engines. The absence of aromatic hydrocarbons, the low sulphur content, or the lower ratio of carbon atoms to hydrogen atoms can favourably influence the emissions performance of engines fuelled with HVO. The high cetane number of HVO requires an appropriate approach to combustion control for proper engine operation. In this study, combustion and exhaust emissions were analysed for pure diesel (ON), hydrotreated oil (HVO) and a 1:1 mixture of HVO and ON. The single-cylinder research engine was subjected to a series of experiments under partially homogeneous mixture combustion conditions (PCCI).
