Abstract
The utility model discloses a kind of multi-cylinder diesel engine, comprise multi-cylinder diesel engine body, described multi-cylinder diesel engine body comprises cylinder, valve mechanism cover and crankcase, described valve mechanism cover is located on cylinder, and be communicated with by valve actuating push rod hole between valve mechanism cover and crankcase, described valve mechanism cover is provided with the first resuscitation apparatus, the second resuscitation apparatus, is also provided with the 3rd resuscitation apparatus on described cylinder, and described the 3rd resuscitation apparatus communicates with crankcase.This multi-cylinder diesel engine, can ensure crankcase inside and external pressure balance, reduces the fault of multi-cylinder diesel engine.
Description
Technical field
The present invention relates to a kind of multi-cylinder diesel engine.
Background technique
Diesel engine is that burning diesel oil obtains exergonic motor, traditional multi-cylinder diesel engine adopts compressed-air actuated way to improve air temperature, make air temperature exceed the self-ignition point of diesel oil, at this moment own ignition when spraying into again diesel oil, diesel spray and air mixing, therefore, diesel engine is without ignition system.The oil supply system of multi-cylinder diesel engine is also relatively simple, and therefore the reliability of diesel engine is better than petrolic.
Resuscitation apparatus is the important component part of diesel engine, resuscitation apparatus is that the crankcase for preventing motor produces high pressure, the inside of playing motor is identical with external pressure, thereby reach the object of cooling, to improve the working environment of crankcase inside, diesel engine in the market generally adopts one or two resuscitation apparatuss, because the gas in crankcase is mainly to enter by valve actuating push rod hole in valve mechanism cover, process resistance is larger, easily exhaust not in time, especially supercharging type bulk temperature is higher, machine oil is by after pressurized machine, the interior temperature of crankcase can be higher, pressure is larger, therefore exhaust just easily causes various multi-cylinder diesel engine faults not in time.
Model utility content
The utility model, for the deficiencies in the prior art, provides a kind of multi-cylinder diesel engine, can ensure crankcase inside and external pressure balance, reduces the fault of multi-cylinder diesel engine.
In order to solve the problems of the technologies described above, the technological scheme that the utility model provides is:
A kind of multi-cylinder diesel engine, comprise multi-cylinder diesel engine body, it is characterized in that: described multi-cylinder diesel engine body comprises cylinder, valve mechanism cover and crankcase, described valve mechanism cover is located on cylinder, and be communicated with by valve actuating push rod hole between valve mechanism cover and crankcase, described valve mechanism cover is provided with the first resuscitation apparatus, the second resuscitation apparatus, is also provided with the 3rd resuscitation apparatus on described cylinder, and described the 3rd resuscitation apparatus communicates with crankcase.
By above technological scheme, with respect to prior art, the utlity model has following beneficial effect:
By design of the present utility model, only be provided with at original multi-cylinder diesel engine on the basis of the first resuscitation apparatus, the second resuscitation apparatus, on cylinder, increase by the 3rd resuscitation apparatus, and the 3rd resuscitation apparatus is directly communicated with crankcase, therefore the pressurized gas of crankcase can lower by resuscitation apparatus fast, thereby better ensure crankcase pressure and external pressure equilibrium of forces, reduced the fault of multi-cylinder diesel engine.
Brief description of the drawings
Figure 1 shows that the first resuscitation apparatus of the utility model setting, the overall schematic of the second resuscitation apparatus;
Figure 2 shows that the structural representation of the 3rd resuscitation apparatus of the utility model setting;
Wherein: 1 is the first resuscitation apparatus, 2 is the second resuscitation apparatus, and 3 is the 3rd resuscitation apparatus.
Embodiment
Accompanying drawing discloses the structural representation of the related preferred embodiment of the utility model without limitation; Explain the technical solution of the utility model below with reference to accompanying drawing.
The setting of resuscitation apparatus, has prevented that the crankcase of motor from producing high pressure, and the inside of playing motor is identical with external pressure, thereby has reached the object of cooling, and to improve the working environment of crankcase inside, the concrete effect of resuscitation apparatus is as follows:
1, prevent that machine oil is rotten;
2, prevent crank shaft oil seal, crankcase liner seepage;
3, prevent that in body, part is corroded;
4, prevent various oil vapor pollution atmosphere;
5, prevent the too high burn oil of internal pressure.
Shown in Fig. 1-Fig. 2, a kind of multi-cylinder diesel engine, comprise multi-cylinder diesel engine body, multi-cylinder diesel engine body comprises cylinder, valve mechanism cover and crankcase, valve mechanism cover is located on cylinder, and is communicated with by valve actuating push rod hole between valve mechanism cover and crankcase, and valve mechanism cover is provided with the first resuscitation apparatus 1, the second resuscitation apparatus 2, on cylinder, being also provided with the 3rd resuscitation apparatus 3, the three resuscitation apparatuss 3 communicates with crankcase.
Because the 3rd resuscitation apparatus 3 directly communicates with crankcase, therefore the pressurized gas of crankcase can lower by resuscitation apparatus fast, thereby have better ensured the balance of crankcase internal pressure and external pressure, have reduced the fault of multi-cylinder diesel engine.
