Effects of alternative marine diesel fuels on the exhaust particle size distributions of an off-road diesel engine
The main objective of this study was to find out how alternative fuels affect the exhaust gas particle size distribution. The fuels are later intended for marine applications. Along with low-sulfur marine light fuel oil ...
Seabed sediment : a natural seasonal heat storage feasibility study
(Estonian Agricultural University, Faculty of Agronomy, 2017)
The new discovery among renewable energy resources, seabed sediment, has been utilised as a heat source for 42 houses in Vaasa since 2008. Sediment heat is annually loaded by the Sun. In this study the amount of annually ...
Low emission engine technologies for future tier 3 legislations : options and case studies
