Marine Diesel Engine
Brief introduction of Marine diesel engine :
Most of the time for a marine host is to work at full load, sometimes in variable load conditions. The ship is often sailing in the bumps, so the marine diesel engine should be able to tilt in the 15 ° ~ 25 ° and dumping 15 ° ~ 35 ° under the conditions of reliable work. Most ships use supercharged diesel engines (see internal combustion engine pressurization), low-power non-pressurized diesel engine only used in small boats. Low-speed diesel engine for the majority of two-stroke machine, medium-speed diesel engine for the majority of four-stroke machine, and high-speed diesel engine are both. Marine two-stroke diesel engine in the form of scavenging scouring gas, gas-valve-type DC scavenging and opposed piston-type gas scavenging. High-power, low-speed diesel engine widely used as fuel, high-speed diesel engine is still more light diesel.
Low speed diesel engine
Direct drive propeller, in order to make the propeller has a high propulsion efficiency, require a lower speed. In the high-speed diesel engine through the gear box to drive the propeller, gear box is also equipped with inverted drive mechanism to achieve propeller reversal, but low-speed diesel engine and some medium-speed diesel engine itself can be reversed. In the high-speed diesel engine also through the generator – motor – propeller to achieve electric drive. When the demand for power can also be used when the multi-machine, low-speed navigation can only work with a host, thereby enhancing the operational economy and reliability. When two main engines are installed on the same boat, they are divided into left and right (depending on the installation position and propeller).
The main trends of marine diesel engines are: to improve the supercharging technology (secondary pressurization, supercharging and supercharging and so on, etc.) to improve the stand-alone power; improve the combustion process, burning low-quality fuel and the use of waste heat to improve Economy; improve reliability and extend the service life; use fault prediction and monitoring, in order to achieve diesel engine automation remote control.
