JY4.8

Introduction to JY4.8 Series Models
  The main structure of the JY4.8series engine,including the body,cylinder head,crankshaft and connecting rod,has been tested for a long time,ensuring the high reliability of the entire machine.
Characteristics of JY4.8 Main Models
  •Using advanced and mature BOSCH electronic control common rail+high efficiency pressurization and medium cooling technology,accurately control the fuel injection,sufficient intake,ensure that the diesel engine in different load conditions,sufficient combustion,low fuel consumption,less emissions.
  •Using the full-flow oil cooler,improve the heat dissipation efficiency by 30%,effectively reduce the oil temperature,make the oil lubricate the parts at a reasonable temperature,and reduce the friction loss.
  •The cylinder head integrated outlet header is designed to reduce the sealing surface and improve the sealing reliability.The piston is cooled by internal cold oil channel,effectively reducing the piston temperature and having a long service life.Meet the performance G3 grade requirements of the generator set.
