Maritime transportation accounts for around 80% of the world freight movements, remarkably contributing to global environmental footprint. Dual fuel engines, running on both gaseous and liquid fuels, represent a viable way toward reduction emissions at cost additional complexity in monitoring activities. Data-driven methods frontier research maritime industrial applications, they usually requir...

The sensors abnormalities, faults, failure detection and diagnosis for marine engines are considered crucial ensuring the engine safe smooth operation. development of such system(s) is typically based on manufacturers experience actuators faults events. This study aims to introduce a novel methodology diagnostics health management in dual fuel by employing combination thermodynamic, functional ...

Two-stroke engines are distinguished by the highest overall efficiency among all main engines. This is not only due to low speed, and large piston stroke, but also high combustion temperature, which result in an increase nitrogen oxides (NO<sub>x</sub>) emission. Technical solutions applied bring into compliance with current NO<sub>x</sub> emission standards set Tier III...

Start of fuel injection and fuel type are two important factors affecting engine performance and exhaust emissions in internal combustion engines. In the present study, a one-dimensional computational fluid dynamics solution with GT-Power software is used to simulate a six-cylinder diesel engine to study the performance and exhaust emissions with different injection timing and alternative fuels...

Diesel engines are widely used to power trucks, buses, passenger cars, locomotives, and ships. These engines power the heavy equipment that plants and harvests crops, tills soil, clears and reshapes land for roads and buildings, and hauls ores from mines to processing centers. Diesel engines generate electricity as portable power sources, peaking units, and emergency backups when line power is ...

Small diesel engines are widely used for commercial vehicle and passenger car applications due to their higher torque requirements, fuel economy, and better thermal efficiency. These engines are exposed to different operating and environmental conditions and hence emissions from these engines are erratic. Strategies are required to enhance performance and reduce engine-out emissions considering...

Indonesia has the potential to develop biomass, such as MSW and wood pellets, a source of energy. Syngas from biomass gasification can be used fuel for dual-fuel diesel engines in order transition We investigated pellets using downdraft reactor with capacity 130–144 kg determine properties produced syngas use engines. Four days are dedicated process preheating sunlight. The experiment was desig...
