Abstract
The utility model relates to a double-layer cylinder cover shell for an electronic control common rail diesel engine, belonging to the internal combustion engine technical field. The utility model is mainly composed of an upper layer cylinder cover shell and a lower layer cylinder cover shell connecting together as a whole body. A wiring socket connector is arranged on the lower layer cylinder cover shell. The utility model has the advantages that: the wiring socket connector is arranged on the lower layer cylinder covers shell, which is convenient for installation; people only needs to detach the upper layer cylinder cover shell when in routine maintenance, which is convenient for maintenance, and the plugging time of the wiring socket connector of a fuel injector is reduced, so that the service life of the wiring is prolonged, and the diesel leakage accident is reduced, the reliability of the whole engine is increased.
Description
Technical field
The utility model relates to the double-deck cylinder head case of a kind of electric-controlled co-rail use for diesel engine, belongs to technical field of internal combustion engines.
Background technique
At present, domestic discharging reaches a lot of electric-controlled co-rail systems that adopt in the motor of national grade III Standard, has increased oil sprayer wire harness in the cylinder head case.Because oil sprayer wire harness need be introduced outside the cylinder cap case in the cylinder cap case, need run through the cylinder head case oil sprayer wire harness plug is installed, for individual layer cylinder head case, the plug of this oil sprayer wire harness not only installs very inconvenience, and all will plug this wiring harness connector when opening the cylinder cap case at every turn and making General Maintenance.Frequent plug has not only reduced the working life of this wire harness, also causes the leakage of oil of connector assembly position through regular meeting.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provides a kind of electric-controlled co-rail use for diesel engine double-deck cylinder head case, can simplify installation, prolongs wire harness working life, improves whole aircraft reliability.
Main solution of the present utility model is achieved in that
The utility model comprises the cylinder head case, it is characterized in that: the cylinder head case connects to form installation wiring connector assembly on lower floor's cylinder head case by upper strata cylinder head case and lower floor's cylinder head case two-part.
Compared with the prior art the utility model has the following advantages:
Since adopt the wire harness connector assembly to be installed on lower floor's cylinder head case, very convenient during installation; Only need pull down upper strata cylinder head case during General Maintenance, both maintain easily, reduce the plug number of times of oil sprayer wire harness connector assembly again, prolong the working life of wire harness, reduce the generation of oil accident, improve the reliability of complete machine.
Description of drawings
Fig. 1 is the utility model upper strata valve mechanism cover shell structure schematic representation.
Fig. 2 is the utility model lower floor valve mechanism cover shell structure schematic representation.
Embodiment
As shown in Figure 1 and Figure 2, the cylinder head case connects to form one by upper strata cylinder head case 1 and lower floor's cylinder head case 2 two-part.Installation wiring connector assembly 3 on lower floor's cylinder head case 2.
Only need during installation directly wire harness connector assembly 3 to be installed on lower floor's cylinder head case 2, only need pull down upper strata cylinder head case 1 during General Maintenance.
Claims (2)
1. the double-deck cylinder head case of electric-controlled co-rail use for diesel engine comprises the cylinder head case, it is characterized in that described cylinder head case is connected to form by upper strata cylinder head case (1) and lower floor's cylinder head case (2).
2. the double-deck cylinder head case of a kind of electric-controlled co-rail use for diesel engine according to claim 1 is characterized in that upward installation wiring connector assembly (3) of described lower floor's cylinder head case (2).
