Abstract
The invention discloses an engine cooling system. The invention is characterized in that the cylinder body of an engine is installed with a cooling water distribution pipe; the distribution pipe is provided with a plurality of channels; and one channel corresponds to one cylinder. The cooling water enters the cylinder body of the engine through each channel for the cooling of the engine, then the cooling liquid enters the cylinder cover through the cylinder body to cool the cylinder cover of the engine, then the cooling liquid returns to a water collector through the cylinder cover, returns to a thermoregulator and finally returns to a water pump. In the invention, a distributive pipe is additionally added under the ordinary engine cylinder body, which ensures that each cylinder corresponds to each channel of a distributive pipe and ensures that the water inflow of each cylinder is identical and the water inflow pressure and the water inflow speed are identical, thus ensuring identical cooling effect of all the cylinders, improving the cooling effect of the engine, simultaneously improving the homogeneous distribution of the cooling liquid in the engine body, improving the fuel economy of the engine and optimizing the discharging of the engine.
Description
Technical field
The invention belongs to automotive field, particularly be applicable to the motor car engine cooling of big discharge capacity.
Background technique
Say for most of motors at present, they are employed all to be the common type of cooling, promptly from 1 cylinder to a last cylinder then cooling liquid get back to thermoregulator from cylinder cap, so just caused 1 cylinder and last cylinder cooling effect poor, also make coolant distribution inhomogeneous.Thereby make discharging and fuel economy not reach more excellent.At present domestic also do not have that engine production producer to can solve above two engine cooling shortcomings.This two aspect is perplexing engine production producer all the time, does not also solve up to now.
Summary of the invention
In order to address the above problem, the invention discloses a kind of engine-cooling system, it is characterized in that: the cooling water distribution piping is installed on engine cylinder-body, has a plurality of passages on the described distribution piping, the corresponding cylinder of passage.
Cooling water enters engine cylinder-body by each passage, carries out engine cooling, and cooling liquid enters cylinder cap by cylinder body engine cylinder cover is cooled off then, and cooling liquid is got back to water-collecting machine by cylinder cap then, returns thermoregulator 4, finally gets back to water pump 3.
Further, described distribution piping is two, be arranged at engine cylinder-body below.
Further, cooling water comes these parts are cooled off, on the pipeline that the backwater mouth of above-mentioned a plurality of parts is all received with radiator is connected by machine oil cooler, cooler for recycled exhaust gas, generator, EGR control valve, turbosupercharger, warm-air drier.One of them water return pipeline of warm-air drier connects swelling water tank.
Further, the air outlet hole of described cooling system is connected on the cylinder cap.
The present invention is by installing distributed water pipe additional below common engine cylinder-body, make each passage of the corresponding distributed water pipe of each cylinder, the inflow that makes each cylinder is identical and intake pressure all is identical with water intake velocity, thereby so just guaranteed the identical cooling effect that improves motor of all cylinder cooling effects, the coolant distribution uniformity in the engine body also is improved simultaneously.Fuel economy to motor increases like this, makes the discharging of motor obtain optimization.

Embodiment
Below in conjunction with accompanying drawing the present invention is specifically described.
As shown in Figure 1, the thermoregulator 4 of this cooling system is that the inlet formula is installed, cooling water is through water pump 3, utilize action of centrifugal force, water pump 3 arrives water pump two distribution pipings 1 installing in the bottom of cylinder body, in 2, as shown in Figure 1, distribution piping 1,2 have a plurality of passages, the corresponding cylinder of each passage, and cooling water enters cylinder body by each passage, carry out engine cooling, cooling liquid enters cylinder cap by cylinder body engine cylinder cover is cooled off then, and cooling liquid is got back to water-collecting machine by cylinder cap then, gets back to thermoregulator 4 at last, finally get back to water pump 3, thereby realize the circulation of cooling system.
The water that water pump 3 comes out also comes the cooled engine outer attachment by the branch road that flows to cylinder body, as shown in Figure 1, water also by annexes such as machine oil cooler 6, EGR (exhaust gas recirculation) cooler 7, generator 8, EGR control valve 9,14, turbosupercharger 10,13, warm-air driers 12, comes these annexes are cooled off.The backwater mouth of these annexes is received on the pipeline that is connected with radiator 5 entirely, thereby participates in the big short circle of cooling water channel, as major cycle A and short circle B.
The air outlet hole of cooling system of the present invention is to be connected on the cylinder cap, has individual branch road to connect swelling water tank 11 on warm-air drier 12 water return pipelines.
