The mandatory implementation of the standards laid out in Energy Efficiency Existing Ship Index (EEXI) and Carbon Intensity Indicator (CII) requires ships to improve their efficiency thereby reduce carbon emissions. To date, steam Rankine cycle (RC) has been widely used recover wasted heat from marine main engines energy-conversion ships. However, current low-speed diesel are usually highly eff...

The tire pyrolysis oil is a waste-derived fuel with lower cetane number and higher den-sity than diesel fuel, but this promising waste-based for compression ignition en-gines. In the European Union, it necessary to increase bio-share of fuels, second-generation blend components are essential achieving 2030 goals. injection characteristics were investigated on Bosch solenoid type common rail (CR...

background: waste produced in dental clinics has been the topic of investigations for many years. these waste materials have important health impacts and are hazardous to humans and the environment. objective: to investigating solid waste production and its management in dental clinics in gorgan, northern iran. methods: in this cross-sectional study, 45 of 143 public dental practices and 5 of 2...

Water injection strategy is considered a promising technique to improve the performance of boosted engine and reduce NOx emission via latent heat water vaporization. Numerous research on has been conducted in-cylinder intake port injection. However, focusing spark ignition (SI) exhaust system still lacking. This study proposed pre-turbocharger turbine (PTWI) concept inlet temperature. was done ...
