While the engine is running, the circulating oil constantly touches these parts, removing the heat from the hot parts and dissipating the heat to the atmosphere through the cylinder block, cylinder head and oil cooler. Several ways to connect the oil radiator In the lubrication system, oil radiator connection has a great influence on the lubrication system, oil radiator in series in the main oil, lubricating oil are through the oil radiator, this connection On the cold start engine oil temperature has an impact, the extension of the lubricating oil resistance to increase oil pressure attenuation. Oil cooler in parallel in the main oil circuit, will lead to the main oil flow and reduced oil flow, affecting the engine lubrication, resulting in excessive wear and tear on the engine, bearings, oil pump internal and external rotor clearance increases, especially when the pump flow is insufficient, This phenomenon is more serious In order to solve the above problems, to ensure reliable lubrication system, the design uses 1 oil pump, one for the lubrication pump, the other for the cooling pump, and dedicated to the radiator oil. According to the conditions of time, the corresponding one-to-one (circle) elastic connection condition and amplitude curve meet the requirements, so the engine and the frame flexible connection scheme is feasible, hanger device parameters, engine water pipes and circuit layout to meet the requirements , To avoid the hanger device and vehicle parts interference, to ensure the rear center plane, the vehicle center plane consistency. Hanger device has sufficient rigidity, damping structure and material to ensure the damping effect of the device, the buffer rubber block has a suitable amount of buffer, durability over. Uniaxial double body oil pump structure Uniaxial double body oil pump, including lubrication pump and cooling pump, are respectively installed on both ends of oil pump drive shaft. The inner and outer rotors of the two pump bodies are respectively provided with two inner rotors Axis, as shown in Figure 7. The oil cooled by the oil cooler is sprayed through the nozzle in the cylinder head cover to the outer wall of the combustion chamber of the cylinder head to directly cool the combustion chamber, meanwhile, it also cools and lubricates the moving parts on the cylinder head and finally returns to the crankcase, as shown in FIG. 1 . Simple design, compact structure, low cost, easy to popularize and popularize, uniaxial double body oil pump is one of the effective measures to improve the ability of engine cooling and lubricating system. This design has now won the national patent. It is understood that this Σ models performance upgrades and pace far exceeded their peers expected.
