Further, described cooling liquid outlet and water pump are arranged at cylinder body the same side;
Further, described cooler intake pipe water intake section is fixed with adpting flange.
The beneficial effects of the utility model are: engine-cooling system of the present utility model, cylinder body water jacket is provided with cooling liquid outlet, and this cooling liquid outlet is communicated with machine oil cooler water intake, when cooling liquid is from water pump enters cylinder body water jacket of engine, a cooling liquid part is by cylinder body water jacket and cylinder cover water jacket, carry out cooling to cylinder body and cylinder cap, another part cooling liquid flows to machine oil cooling liquid by cooling liquid outlet, two-part cooling liquid is finally converged formation circulation loop at pump intake place, because the cooling liquid of the machine oil cooler of flowing through is to draw from cylinder body water jacket, cooling liquid is not because cooling cylinder body and cylinder cap heat up, therefore flow through, the coolant temperature of machine oil cooler is lower, cooling capacity to machine oil is stronger, thereby significantly reduce the wearing and tearing of motor.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is circulation schematic diagram of the present utility model;
Fig. 2 is structural representation of the present utility model.
Embodiment
Fig. 1 is circulation schematic diagram of the present utility model, Fig. 2 is structural representation of the present utility model, as shown in the figure, engine-cooling system in the present embodiment, comprise water pump 5, cylinder body water jacket, cylinder cover water jacket and machine oil cooler 2, cylinder body water jacket and cylinder cover water jacket are interconnected, cylinder body water jacket is provided with cooling liquid outlet 6, cooling liquid outlet 6 is connected with machine oil cooler 2 water intakes by cooler intake pipe 1, machine oil cooler 2 water outlets are communicated with water pump 5 water intakes by cooler outlet pipe 3, water pump 5 water outlets are connected in cylinder body water jacket water intake, when cooling liquid enters cylinder body water jacket of engine from water pump 5, a cooling liquid part is by cylinder body water jacket and cylinder cover water jacket, carry out cooling to cylinder body and cylinder cap, another part cooling liquid flows to machine oil cooling liquid by cooling liquid outlet 6, two-part cooling liquid is finally converged formation circulation loop in water pump 5 water inlets, because the cooling liquid of the machine oil cooler 2 of flowing through is to draw from cylinder body water jacket, cooling liquid is not because cooling cylinder body and cylinder cap heat up, therefore flow through, the coolant temperature of machine oil cooler 2 is lower, cooling capacity to machine oil is stronger, thereby significantly reduce the wearing and tearing of motor.
In the present embodiment, also comprise thermoregulator and radiator, cylinder cover water jacket water outlet is connected in water inlet of radiator by radiator inleting pipe, radiator outlet is connected in thermoregulator water intake by radiator outlet pipe and thermoregulator water outlet is connected with water pump 5 water intakes, thermoregulator on available engine is arranged on cooling liquid outlet pipe place conventionally, not only structurally layout is more loaded down with trivial details, and can make motor job insecurity between warming up period, the wearing and tearing of booster engine.Be stranded for asking in the engine warm-up phase, device is larger in thermoregulator amplitude of accommodation in the time regulating engine cooling water temperature at engine water outlet place, in the time that the main valve of thermoregulator has just been opened, cooling water in radiator just promptly pours in engine cylinder-body, water temperature in primosome cylinder body just declines suddenly, the main valve of thermoregulator is closed again, until when the water temperature in engine cylinder-body raises again, main valve in thermoregulator is opened once more, cold water in radiator pours in engine cylinder-body once more, water temperature in engine cylinder-body is declined again suddenly, thermoregulator main valve is closed once more.So periodically repeatedly, until in radiator and when the cooling water temperature of motor is all increased to the open temp of thermoregulator, just switch water outlet no longer so repeatedly of the main valve of thermoregulator.During engine warm-up, cooling water temperature in engine cylinder-body sharply changes so repeatedly, bad while making engine gasoline atomization fashion, thereby make the motor can not steady running, and therefore, the engine-cooling system in the present embodiment, thermoregulator is arranged at water pump 5 inlet end, thereby more responsive to water inflow of the engine control, degree of regulation is higher, can not make the water temperature in engine cylinder-body produce large fluctuation, thereby make engine running steady.
