120KW open type diesel generator yuchai engine YC4A180L
The 120KW diesel generator set is powered by the high-quality diesel engine YC4A180L-D20 produced by Yuchai. The YC4A series engine is a classic power product developed by Yuchai, with more than 400,000 units in the market. The engine for generator set developed on its basis has the advantages of reliability and durability, energy saving and environmental protection, compact structure, strong transient loading capacity, and good maintainability. The main structure of the engine body, cylinder head, crankshaft connecting rod and other main structures have been tested for a long time to ensure the high reliability of the whole machine.
The advanced and mature BOSCH electronically controlled common rail + high-efficiency supercharged intercooling technology is adopted to precisely control the fuel injection amount and ensure sufficient intake air to ensure that the diesel engine has sufficient combustion, low fuel consumption and low emissions under different load conditions.
1. Using a full-flow oil cooler, the heat dissipation efficiency is increased by 30%, which effectively reduces the oil temperature, so that the oil lubricates the parts at a reasonable temperature and reduces friction loss.
2. The design of the integrated water outlet pipe in the cylinder head is adopted to reduce the sealing surface and improve the sealing reliability.
3. The piston is cooled by the inner cooling oil passage, which effectively reduces the temperature of the piston and has a long service life.
4. Meet the G3 level requirements of generator set performance
