Many marine vessels do not provide a way for captain and crew to measure and monitor fuel usage while underway. An optimum system onboard would include the ability to instantaneously monitor fuel burn rates from the wheelhouse. Individual engine and generator burn rates would be included, as well as fuel tank levels.
Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats , most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller , or less frequently, in pump-jets , an ...
2006: Westport HD Engine and LNG Fuel System for heavy-duty trucking applications was launched. The HPDI technology is based on the 15-litre Cummins ISX but is adaptable to other OEM engines as well. 2008: Westport formed a joint venture with Weichai Power, China's largest heavy-duty engine manufacturer, and Hong Kong Peterson (CNG) Equipment ...
The podded design typically achieved a 9% better fuel efficiency than the conventional propulsion system when it was first installed in the 1990s. In the meantime, improvements to the conventional designs have shrunk the gap to 6–8%, but on the other hand the hydrodynamic flow around the Azipod has been improved by fin retrofits and a dynamic ...
One drawback was the instability and scarcity of the fuel involved. Another was that while the system produced high underwater speeds, it was extravagant with fuel; the first boat, V-80, required 28 tons of fuel to travel 50 nautical miles (93 kilometres), and the final designs were little better.
It has twin double overhead camshafts.A marine version was planned for 522 kW/700 hp at 3,900 rpm. [10] The cylinder banks' angle is 80 degrees. [11] The RED A03-200 series is a derivative developed for very high-altitude operation up to 15 km (49,000 ft), with a maximum rating of 460 hp (340 kW) at FL250.
