Abstract
The utility model relates to a four-stroke internal combustion engine body which comprises a cylinder body and a crank case. A water jacket and a cooling water circulation cooling cylinder jacket are arranged around the cylinder body, and the air admission side of the cylinder body is provided with a large water cavity. The water cavity and the water jacket are communicated by water holes, and a machine oil cooler is installed on the end surface of the water cavity. A plate-fin type machine oil cooler in the machine oil cooler is arranged in the large water cavity.
Description
The utility model relates to the body of a kind of internal-combustion engine, particularly quartastroke engine, and described body structurally has certain improvement for solving the lubricated of moving element.
As known to the public; body is a vitals of internal-combustion engine; it is the skeleton of internal-combustion engine; usually body is made up of cylinder block and crankcase; be provided with water jacket around the cylinder block, cooling water circulation cooling cylinder sleeve is arranged, piston is housed in the cylinder; by connecting rod bent axle is passed in the to-and-fro motion of piston, bent axle is made high speed rotating.Connecting rod is connected with bent axle, reaches crankshaft journal and all is equipped with bearing shell with the sliding bearing contacting point of fixing, and these parts all must have lubricated fully.Machine oil adopts the suitable trade mark, and keeps the characteristic of machine oil in suitable temperature, and temperature is too high and cross low all improper.But the above-mentioned moving element of mentioning closely links to each other with cylinder body mostly, cylinder block is a high-temperature component, machine oil is heated up in greasing inevitably, sometimes above 130 ℃, the too high oil of the temperature of machine oil is diluted, can not form oil film and lose lubrication, cause bearing shell and axle journal to carry out dry friction and bearing liner burnout, damage device.So must control the temperature of machine oil, the setting of machine oil cooling unit just seems particularly important like this.But most of internal-combustion engines all do not have cooling unit.In known internal-combustion engine, for example six cylinder machines of Dong Feng Auto Corporation's production are provided with a kind of machine oil cartridge type cooling unit, and the cylinder machine oil cooler is carried on the back outside machine, with connections such as pipelines, structure is not only not compact, but also does not sternly leak because of sealing for tubing joints easily.Therefore, a kind of machine oil cooling unit of suitable construction is actual needed.
The purpose of this utility model is to provide a kind of body of quartastroke engine, and the structure of described body and additional device thereof are convenient to the cooling of oil temperature, thus the temperature of control machine oil, to reach good lubricating effect.
For achieving the above object, scheme of the present utility model is: the air inlet side in cylinder block is provided with a big water cavity, communicated by the water hole between water cavity and the water jacket, the machine oil cooling unit is installed on the end face of water cavity, and the plate fin oil cooler in the machine oil cooling unit is placed in the big water cavity.
Adopt such scheme, from cooling-cycle device for example the water that pumps of water pump at first enter big water cavity, enter cylinder block by three water jacket holes then, the not high water of temperature this moment flows through plate fin oil cooler, by entering the water jacket circulation in the cylinder block, the temperature of machine oil is controlled like this, has guaranteed lubricating quality.
Below by diagram and embodiment scheme is described in more detail.
Fig. 1 is equipped with the outline drawing of machine oil cooling unit for the quartastroke engine body.
Fig. 2 is machine oil cooling unit mounting point figure on the quartastroke engine body.
The machine oil cooling unit assembly erection drawing of Fig. 3 for installing on the quartastroke engine body.
Fig. 4 be among Fig. 3 the plate fin oil cooler A in the machine oil cooling unit assembly to view.
Be illustrated in figure 1 as the body (1) of quartastroke engine and be installed in machine oil cooler (2) on the body (1).The top of body (1) is cylinder block, the bottom is a crankcase, studs with cylinder sleeve on the cylinder block, and cooler is installed in the air inlet side of cylinder block, machine oil cooler has a board-like housing (3), and rotary oil filter annexes such as (4) closely is installed on the board-like housing.
See the internal combustion (IC) engine airframe of Fig. 2, on the next door (5) of former air inlet side, be with the sidewall (6) of a circle sealing, to form the approximate rectangular big water cavity (7) of an opening, water enters water cavity by body front-end face (8) hole, with after water cavity is diverted between each water jacket circulates, have the mouth of a river (9) that three pore sizes do not wait on the next door (5) of formation water cavity bottom surface, arrange from front to back by body.Open on the water jacket position between two cylinders at each mouth of a river, has pipeline to be connected with cooling waterpump in (8) hole.Be provided with the basal plane (10) installed for machine oil cooler (2) and fix at the end face of water cavity by securing means.
See the machine oil cooler of Fig. 3, described machine oil cooler has a board-like housing (3), and housing (3) is the rectangular enclosure of an opening.Promptly constitute by a ring wall (11) and a base plate (12), there are two flange plate with holes (13) and (14) in the inside, Kong Yuyi the oil filter (4) of dish (13) communicates, plate fin oil cooler (15) is installed between two flange plate, (15) have two flanges with holes (16) and (17), the position is corresponding with flange plate (13) and (14) respectively, so that tighten together by screw.The end face (18) of housing (3) is the attachment face of an astragal screw hole, and housing (3) also is separated with a circle liner (19) with water leakage when being installed on the body.
View shown in Figure 4 has been represented the principle that plate fin oil cooler cools off machine oil, described cooler has three overlapping placements and the cooling fin of certain intervals is arranged, fin all is hollow, two ends are connected with (21) with pipeline (20), the end face of pipeline respectively has adpting flange (16) and (17), the oil that comes from rotation filter cleaner (4) enters three stacked fins by flange (16), enters the pipeline (21) of opposite side again, and the pipeline that connects from flange (17) flows out.Because fin is to be bathed in the water, so machine oil is well dispelled the heat and is cooled.
Machine oil cooling unit of the present utility model owing to adopt said structure, makes the mean temperature of machine oil reduce 15-20 ℃ approximately than the type that cooling unit is not set, thereby has improved the lubricating condition of moving element, seldom occurs because of the lubricated inappropriate fault of bringing.
In sum, the utility model is effective.
