Weichai WD618 series marine diesel engine is in WD615 series diesel engine to increase power on the basis of the development of increased travel into. I used to broaden the scope of WD618 series diesel engine, combined with the ship machine requirements, in accordance with the relevant national standards and shipping regulations, developed WD618C series marine diesel engine.
Weichai WD618 series marine diesel engine has a great power reserves, low fuel consumption, emissions of good , high reliability, simple operation and convenient maintenance. Power range 180-275kW, speed range 1500-2150r/min, can be used in a variety of marine power. Unit Optional MP270A, 300, D300 and other models gearbox. Ratio 2:1-7:1.
structural advantages of marine diesel engine
1.'s unique main bearing frame structure, body rigidity, vibration and low noise.
2. A cylinder of a cover for vehicle maintenance, reduce maintenance costs.
3. The main components of global sourcing from time to time to achieve high engine configuration.
4. Engine accessories installation is complete, air cooler, sea water heat exchanger installed in the engine for easy cabin layout.
5. Diesel engine cooling system inside and outside the two-cycle water-cooled, diesel engine with fresh water circulating cooling, external circulation of fresh water with seawater through the sea of fresh water cooling heat exchanger improved engine life.
6. Improve the protection and control system that uses diesel engine function monitoring device, can the engine speed, water temperature, oil temperature and pressure measurements show automatically when the engine Parameter overrun alarm and automatically shutdown when, optional remote control device.
7. Using exhaust pipe the water jacket to keep the cabin temperature is low.
8. Supporting adaptability, WD615C, WD618C series diesel engine flywheel, flywheel housing, engine monitoring instruments, water, exhaust pipe cover, sea water pump and other components common. Engine mounting dimensions, flywheel and flywheel housing are the same size, convenient for supporting and maintenance.
9. Crankshaft pulley slot is reserved for the front pulley and flange connection for users to use external power output device.
fuel system
1. diesel filter: fine filter paper core in series with double-barrel type, with water separation function, increase filtration effect;
2 . Injector porous small aperture to improve the physical and chemical quality.
intake and exhaust system
1. General structure of the appearance of bread with the exhaust pipe insulation to reduce cabin temperature. The peripherals are insulated room to improve the appearance quality and safety.
2. Exhaust pipe water jacket structure as a whole, the use of sea water cooling exhaust pipe backlight to reduce the cabin temperature;
lubrication system
shell and tube oil cooler replaced by a plate-fin type, good cooling effect and reduce the oil temperature;
electrical control systems
Diesel Monitor diesel engine operating parameters for the visiting team automatic measurement display, parameter overrun alarm shutdown.
marine diesel engine performance benefits
low fuel consumption : the minimum fuel consumption 198g/kW.h, rational design of the intake system, fuel supply and so broaden the diesel engine operating range.
flat curve with low fuel consumption, speed in the range of common conditions can maintain low fuel consumption.
strong impetus : a large power reserve, the maximum output power up to 275kW, fast speed , speed high.
low noise, low emission, low smoke degrees : noise less than 108dB (A ), Euro II emission standards can be achieved, and smoke less than 1.2Rb.
