Abstract
A cylinder block of an engine comprises a gantry type cylinder block provided with a crankcase inner wall and a main oil gallery hole. The cylinder block of the engine is characterized in that the crankcase inner wall of the cylinder block is provided with a spray nozzle connecting hole communicated with the main oil gallery hole and a spray nozzle mounting hole. By the aid of the cylinder block of the engine, a piston cooling oil injection device can be mounted conveniently and stably and can be communicated with a main oil gallery of an engine lubricating system, and accordingly necessary lubricating oil can be provided to a piston in high-temperature, high-load and high-speed movement for cooling , and the cylinder block for the engine is favorable for reducing friction loss of the piston, reduces cylinder score probability, and increases economical efficiency and reliability of the engine. In addition, the cylinder block of the engine is mainly used for matching power of a light go-anywhere vehicle, a light passenger car, a light lorry and a light passenger and goods double-service truck, and can meet requirements of gasoline engines with low pollution and low fuel oil consumption and the like in Euro III emission standard.
Description
Technical field
The utility model belongs to petrolic cylinder block, relates to a kind of cylinder block of motor, is the improvement of prior art.The cylinder block that be specially adapted to planer-type, do not have cylinder sleeve, comprise the oil spout structure, satisfy the low pollution of Europe III emission standard, low fuel oil consumes petrol engine adopts.
Background technique
Along with the highway in China transportation is hanged down the pollutionization development towards high speed, economic, comfortable reaching, and the deflation day by day of national energy policy, for satisfying the fuel limit rules of all kinds of light buses, light duty cross-country car, light-duty notchback, light truck, Economy to motor is had higher requirement, realize that these requirements will carry out architecture advances by this class important spare part of countercylinder body, to satisfy the engine performance requirement.
Summary of the invention
The purpose of this utility model is intended to overcome deficiency of the prior art, and a kind of simple in structure, cylinder block of comprising the motor of connection piston cooling fueling injection equipment structure is provided.Adopt in the cylinder block that be specially adapted to planer-type, do not have cylinder sleeve, comprise the oil spout structure, satisfy the low pollution of Europe III emission standard, low fuel oil consumes petrol engine.
Content of the present utility model is: a kind of cylinder block of motor, comprise: the planer-type cylinder block that crankcase inwall and mail gallery holes are arranged, its feature part is: the nozzle attachment hole (3) that is connected with described mail gallery holes (2) is arranged on the crankcase inwall (1) of described cylinder block, be used for mail gallery holes (2) is connected with piston cooling fueling injection equipment.
In the content of the present utility model: on the crankcase inwall (1) of described cylinder block nozzle mounting hole (4) can also be arranged, be used for fixing piston cooling fueling injection equipment is installed.
Described piston cooling fueling injection equipment sees that the invention and created name of submitting simultaneously with the application is the record of the utility application file of " a kind of cooling jet of engine piston ".
Compared with prior art, the utlity model has following characteristics and beneficial effect:
(1) adopts the utility model, can make things convenient for and piston cooling fueling injection equipment firmly is installed and is connected with the main oil gallery of engine lubrication system, thereby the piston that can be high temperature, high load and high-speed motion provides necessary lubricant oil to cool off, help reducing the friction loss of piston, reduce the scuffing of cylinder bore probability, improve the Economy and the reliability of motor;
(2) simple in structure, cost is low, makes easily, process easy to use, be mainly used in the mating power of light duty cross-country car, light bus, light truck and light-duty notchback, can satisfy the needs of the low pollution of Europe III emission standard, low fuel oil consumption petrol engine etc., practical.

Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Embodiment 1: referring to each accompanying drawing.
A kind of cylinder block of motor comprises: the planer-type cylinder block that crankcase inwall 1 and mail gallery holes 2 are arranged; The nozzle attachment hole 3 that is connected with described mail gallery holes 2 is arranged on the crankcase inwall 1 of described cylinder block; On the crankcase inwall 1 of described cylinder block nozzle mounting hole 4 is arranged.
This embodiment's cylinder block adopts alloy cast iron, and planer-type, no cylinder sleeve structural type can make its compact structure like this, and rigidity and intensity are better, and cylinder block is classified array as, and the cylinder bore dia is 95 millimeters, and cylinder core distance is 102.5 millimeters, 271.5 millimeters of cylinder body height overalls.
When adopting this embodiment's cylinder block, piston is cooled off on the crankcase inwall 1 that fueling injection equipment is installed in cylinder block.Described piston cooling fueling injection equipment sees the record for the utility application file of " a kind of cooling jet of engine piston " of invention and created name that the application submits simultaneously; The cooling jet of this engine piston, by the hollow valve body that annular table is arranged in oil inlet hole and the oil inlet hole and oil outlet is arranged is arranged, place the spring in the valve body, place steel ball between valve body inner spring and the annular table (under the pressure of spring, steel ball stops up and the sealing oil inlet hole), one end and valve body fixed seal connection, another section be positioned at valve body and with the obstruction of spring pivot bush unit, jet pipe that an end and the oil outlet of valve body fixedly are communicated with and the mounting plate that is fixedly connected on the valve body constitute.During assembling, with valve body and nozzle attachment hole 3 be tightly fixed understanding, the oil inlet hole of valve body is connected with the mail gallery holes 2 of engine lubrication system, mounting plate is connected firmly with the nozzle mounting hole 4 fixedly connected piston cooling fueling injection equipments that make, and jet pipe is connected with the lubricating cooling oil road of engine piston.During work, get oil, cool off fueling injection equipment directly lube pistons inwall, cooling piston top by piston from the main oil gallery of engine lubrication system.
Adopt the petrol engine after the utility model improves, emission performance reaches EUR0 III rules, satisfy GB18352.3-2005 " light-duty vehicle pollutant emission limit and method of testing (the III) " mandatory standard that country is about to enforcement, satisfy the local emission standard in DB11/105-1998 and DB11/044-1999 Beijing simultaneously.
