| dc.description.abstract | This textbook on selection and installation of fishing boat engine has been compiled for the Regional Training Course for Extension Officers and also for use by the Marine Engineering Course trainees of the SEAFDEC Training Department. The spark ignition volatile-fuel engine, excellent as it is, is wasteful when compared with the diesel engine in terms of thermal efficiency. The latter delivers 30-38 percent while the spark ignition engine 22-25 percent, and consequently, it is economical with fuel. It is also a good puller (high torque), reliable and robust and its mechanically accurate metering pump replaces the carburettor and electrical ignition apparatus which is vulnerable in rough sea conditions. | en |
