As the air-cooled diesel engine running, relying on forced air to take away the heat, so no need to set the water cooling system, cylinder head, cylinder and other parts do not need to set the water jacket, no water pumps, radiators and thermostats and other parts , Thus simplifying the structure and reducing costs. Compared with the same power of water-cooled diesel engine, the length of the air-cooled diesel engine to be shorter, the height also because of no radiator and low, the width is basically the same, so its weight decreased accordingly.
2. Excellent low temperature performance
The Dawes air-cooled diesel engine uses deep-shaped combustion chamber, porous fuel injection, direct fuel injection combustion, in a 20 ℃ under the environmental conditions, can start without difficulty, especially for cold areas and winter use. The fuel injection pressure required for the combustion chamber is relatively low, the nozzle is not easy to block and stuck, not only reliable but also fuel burned completely, fuel economy, less pollution, the fuel consumption rate, the minimum fuel consumption rate of 212g / (kw · h). Diesel engine in the case of -35 ℃, still very good start and reliable work, there will be no risk of cracking the body, do not need to use antifreeze, the low temperature performance.
3. High thermal efficiency and good economy
As the air-cooled diesel engine to the air less heat, so the cooling air volume is only about 2/3 of the water-cooled diesel engine. This is because the air-cooled diesel engine in the gas temperature is certain circumstances, the higher the cylinder wall temperature, diesel engine emissions to the air less heat, the higher the thermal efficiency, fuel consumption will be reduced, the better the economy. Usually the temperature of the air-cooled diesel engine cylinder wall temperature than the water-cooled diesel engine wall temperature is several degrees higher, therefore, its thermal efficiency is higher than the water-cooled diesel engine.
4. Long service life
Air-cooled diesel engine due to high temperature, high temperature, to maximize the avoidance of acid corrosion and wear, while reducing the diesel engine in the dew point of the following working hours, and thus air-cooled diesel engine parts corrosion, cavitation, corrosion is small, Cover, radiator does not produce the accumulation of scale defects, its long service life. It can be seen, air-cooled diesel engine mobility is good, warm up time is short, easy to start, eliminating the addition of cooling water, release the burden of cooling water, do not worry about the cylinder, cylinder head, radiator and other cracks occurred in the accident, Therefore, its use of high reliability, less failure, long life, easy maintenance.
