A silencer quiets the exhaust output from a marine engine by injecting a spray of cooling water into the exhaust passageway to mix with and cool the exhaust gases before output from the passageway. The exhaust passageway preferably enlarges substantially in cross-sectional area in the region where...
Methods, systems, and apparatuses for exhaust silencers for engines, such as microturbines, are described. An exhaust silencer reduces noise produced by an engine. While passing through an exhaust silencer, an exhaust stream from the eng... Yamamoto,Kazuo,Kaita,... 被引量: 0发表: 0年 Exhaus...
TZJ Series Marine Spark Trap Exhaust Engine Generator SilencerProduct Description DN65-DN1800 diesel engine exhaust silencer Product Type: collection type, collision type, negative type extinguisher; resistance, resistance, impedance composite muffler; Design range: diameter 65m...
exhaust gas temperature is needed, a solution exists for additional automatic control of the EGB, the so-called economiser energy control (EEC). Forcing an open EGB at loads where the EGB is normally closed re- sults in a higher mixed exhaust gas temperature, but with an SFOC penalty on...
A wet exhaust has several advantages over a dry exhaust. The injected water lowers the temperature of the exhaust gases from as high as 2000° F. to below 212° F., cooling the gases sufficiently to allow the use of flexible hose at or shortly after the water injection point. Flexible ho...
An exhaust muffler for a marine engine comprises a first vertically oriented tubular member having a lower end sealingly extended through the bottom of a main body chamber and an upper end extending upwardly through the top of the chamber. A second tubular member surrounds and is spaced from ...
PURPOSE: To shorten an exhaust piping from an exhaust manifold and to reduce the noise to the low level by designing a diverting means for diverting the mixture flow in the longitudinal direction of a container, and forcibly diverting the same to an upper part and a lower part till the ...
The invention provides a silencer (1) for a marine engine being arranged for connection to an exhaust outlet (5) of an in board marine engine, the silencer comprising: a housing defining a helmholtz resonator chamber (8) and an expansion chamber (10); and, a baffle (12) arranged within ...
In the paper, exhaust noise control of marine diesel engine was studied by using the hybrid silencer, which was composed of virtually divided array of concentric hole-cavity resonators and conventional absorptive silencer. A series of tests including field tests were performed to investigate the ...
