Abstract
Characteristics of Emissions from a Portable Two-stroke Gasoline Engine
Highlights
Environmental greening is a critical construction project in metropolitan cities around the world
Experimental results show that the HC and Carbon monoxide (CO) emission factors (EFs) decreased with increasing engine speed, while nitrogen oxides (NOx) EFs exhibited the opposite trend
This study focuses on the use of different 2-stroke engine oil additives in a P2SGE with operation loads of idling
Summary
Environmental greening (such as park green space and planting) is a critical construction project in metropolitan cities around the world. In the maintenance of green landscapes, small or light engine powered apparatuses are often adopted to save human resources and increase work efficiency. These devices (such as mowers and leaf blowers) must be lightweight to reduce the cost in production, so they are often equipped with portable two-stroke gasoline engines (P2SGE), which have almost no exhaust gas treatment equipment. This fact generally results in the emission of large amounts of air pollutants, including carbon dioxide (CO2), volatile organic compounds (VOCs), polycyclic aromatic. The added 2-cycle engine oil is frequently hard to be entirely burned in such a short time in the
