Abstract
The utility model relates to a lubricating system of an engine, which comprises an oil cooler communicated with an oil pump and an oil filter. Engine oil after being filtered enters a cylinder body main oil duct; the cylinder body main oil duct is communicated with a main bearing oil duct and a cooling nozzle oil duct and is also communicated with an oil duct with a gear chamber at one end. The cylinder body main oil duct is communicated with an air distribution mechanism in the corresponding position through a cylinder cover oil duct. Because the cylinder body main oil duct is communicated with the air distribution mechanism in the corresponding position through the cylinder cover oil duct, the lubricating system of the engine improves the effective distribution of oil pressure in all parts, in particular to a cylinder cover lubricating part under the condition of no addition of the flow capacity of the oil pump, so that all the parts are uniformly and completely lubricated, thereby overcoming the problems that the cylinder cover main oil duct is too long, and a camshaft and a rocker arm are not lubricated uniformly.
Description
Technical field
The utility model relates to a kind of motor, particularly relates to a kind of engine lubrication system.
Background technique
At present, in engine lubrication system, machine oil forms certain pressure under the effect of oil pump, behind cold filtration, enters cylinder body main oil gallery and cylinder cap main oil gallery, respectively each friction pair is lubricated.In main oil gallery, to cylinder cap oil duct fuel feeding, successively each friction pair is lubricated again by single oil duct.Because cylinder cap oil duct end-to-end distance main oil gallery distance is far away, this place's underpressure often occurs, lubricated inadequate phenomenon.Often cause the terminal premature failure of camshaft, problems such as port timing deviation occur, influence burning and discharging.
Summary of the invention
The purpose of this utility model is to provide a kind of engine lubrication system, solves the underpressure that exists in the available engine lubrication system, uneven problem.The engine oil pressure at reasonable Arrangement oil circuit, each position of distribution lubrication system.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of engine lubrication system, comprise that oil pump is communicated with machine oil cooler and oil filter, machine oil after the filtration enters the cylinder body main oil gallery, the cylinder body main oil gallery is communicated with one group of main bearing oil duct and cooling jet oil duct, and the cylinder body main oil gallery is communicated with an end gear chamber oil duct; It is characterized in that: the cylinder body main oil gallery is the distribution device that is communicated with the relevant position by one group of cylinder cap oil duct.
In the engine lubrication system that described oil circuit is arranged, the machine oil after the filtration enters the cylinder body main oil gallery, and with respect to six cylinder engine, this oil duct is provided with seven main bearing oil ducts, six cooling jet oil ducts, three cylinder cap oil ducts, a gear chamber oil duct.According to the intensity difference of each friction pair, the corresponding change of the area ratio of each oil duct.
Good effect of the present utility model: because the cylinder body main oil gallery is the distribution device that is communicated with the relevant position by one group of cylinder cap oil duct, this engine lubrication system has significant advantage.Under the situation that does not increase oil pump capacity, having improved everywhere, oil pressure effectively distributes, cylinder cap lubricant housings particularly, it is evenly lubricated fully that each position is obtained, overcome because the cylinder cap main oil gallery is oversize, camshaft and rocking arm lubricate uneven problem, thereby ensured the actual life of camshaft, framework, rocking arm, gives full play to the function of lubrication system.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the utility model embodiment lubrication system schematic representation.
Among the figure: 1. oil pump, 2. machine oil cooler, 3. oil filter, 4. cylinder body main oil gallery, 5. cooling jet oil duct, 6. main bearing oil duct, 7. gear chamber oil duct, the 8. first cylinder cap oil duct, the 9. second cylinder cap oil duct, 10. the 3rd cylinder cap oil duct.
Embodiment
As shown in Figure 1, a kind of six cylinder engine lubrication system, comprise that oil pump 1 is communicated with machine oil cooler 2 and oil filter 3, machine oil after the filtration enters cylinder body main oil gallery 4, cylinder body main oil gallery 4 is communicated with seven main bearing oil ducts 6 and six cooling jet oil ducts 5, and cylinder body main oil gallery 4 one ends are communicated with gear chamber oil duct 7; Cylinder body main oil gallery 4 is the distribution devices that are communicated with the relevant position by three cylinder cap oil ducts.
Oil pump 1 provides pressure machine oil for this lubrication system, and machine oil at first cools off through machine oil cooler 2, then enters oil filter 3 and filters; The machine oil of cleaning enters from the neutral position of main oil gallery 4, leads to two ends respectively and is assigned to each lubricant housings and is lubricated.With respect to six cylinder engine, be respectively equipped with seven main bearing oil ducts and six cooling jet oil ducts; Be provided with gear chamber oil duct 7 at main oil gallery one end, this oil duct is that chain, accessory system carry out fuel feeding.Main oil gallery 4 is provided with three cylinder cap oil ducts 8,9,10, and these three oil ducts are separate, and the distribution device to the cylinder cap relevant position carries out fuel feeding.Changed the thinking of traditional single oil duct supply cylinder cap main oil gallery, oil pressure is even everywhere to make cylinder cap, guarantees the normal fuel injection of camshaft and rocking arm.Analyze by CFD, under the situation of identical oil pump capacity, the oil pressure of whole system can rationally distribute, be in the cylinder cap end oil pressure be improved significantly, the reliability of whole lubricating system is further improved.
Claims (3)
1, a kind of engine lubrication system comprises that oil pump is communicated with machine oil cooler and oil filter, and the machine oil after the filtration enters the cylinder body main oil gallery, and the cylinder body main oil gallery is communicated with one group of main bearing oil duct and cooling jet oil duct, and the cylinder body main oil gallery is communicated with an end gear chamber oil duct; It is characterized in that: the cylinder body main oil gallery is the distribution device that is communicated with the relevant position by one group of cylinder cap oil duct.
2, engine lubrication system according to claim 1 is characterized in that: described one group of cylinder cap oil duct is three.
