Abstract
The utility model discloses an oil-gas balance chamber structure of diesel engine cylinder. The utility model comprises a fuel gas balance chamber, an air path of the balance chamber, a cam axle hole, an air path of a crank axle box, a chiller water cavity, a baffle of the chiller water cavity, a baffle of a cylinder hole and a water inlet, a water inlet of the cylinder hole, a crank axle box and a tappet hole. The utility model is characterized in that the fuel gas balance chamber is cast above the tappet hole of the gas cylinder body. The fuel gas balance chamber of the gas cylinder body can balance the pressure of the fuel gas of the crank axle box of the diesel among each cylinder. The gas losing energy of the diesel pump is effectively reduced.
Description
Technical field
The utility model relates to diesel engine oil gas balance cylinder structure, relates in particular to a kind of crankcase oils atmospheric pressure of six-cylinder diesel engine that makes and reach balance oil gas balance cylinder structure between each cylinder.
Background technique
Existing diesel does not design the gas and oil equilibration chamber, can't reduce the pumping loss merit of diesel engine, has caused the diesel engine idle work to increase, and Economy is relatively poor.
Summary of the invention
The utility model has overcome not enough shortcoming of the prior art, and a kind of gas and oil equilibration cell structure that reduces Diesel engine pump gas lost work is provided.
The purpose of this utility model is to provide cylinder of diesel engine gas and oil equilibration cell structure a kind of simple in structure, easily manufactured.Comprise by gas and oil equilibration chamber, balance cylinder's air vent, camshaft hole, crank case vent road, cooler water cavity, cooler water cavity dividing plate, cylinder hole water intake dividing plate, cylinder hole water intake, crankcase, tappet hole.Be provided with the gas and oil equilibration chamber on the top in tappet hole, the side in tappet hole is provided with balance cylinder's air vent.Be provided with the crank case vent road between camshaft hole and the crankcase.By the oil gas in the crankcase is guided in the balance cylinder, make that crankcase pressure tends to balance between each cylinder, thereby reach the purpose that reduces the pumping loss merit.
Compared with prior art, the utility model has reduced Diesel engine pump gas lost work, has improved the Economy of diesel engine.
Description of drawings
It is such that cylinder block gas and oil equilibration cell structure of the present utility model constitutes:
Fig. 1 is a cylinder block of the present utility model balance cylinder sectional elevation.
Fig. 2 presses A-A sectional view among Fig. 1 for the utility model.
Fig. 3 presses B-B sectional view among Fig. 2 for the utility model.
Fig. 4 presses D-D sectional view among Fig. 2 for the utility model.
Fig. 5 presses C-C sectional view among Fig. 2 for the utility model.
Among Fig. 1～Fig. 5, gas and oil equilibration chamber (1), balance cylinder's air vent (2), camshaft hole (3), crank case vent road (4), cooler water cavity (5), cooler water cavity dividing plate (6), cylinder hole water intake dividing plate (7), cylinder hole water intake (8), crankcase (9), tappet hole (10).
Embodiment
The utility model provides a kind of cylinder of diesel engine gas and oil equilibration cell structure, comprising: gas and oil equilibration chamber, balance cylinder's air vent, camshaft hole, crank case vent road, cooler water cavity, cooler water cavity dividing plate, cylinder hole water intake dividing plate, cylinder hole water intake, crankcase, tappet hole.Embodiment is as follows: the top, tappet hole (10) in cylinder block casts out gas and oil equilibration chamber (1), next door in the tappet hole (10) of every cylinder increases balance cylinder's air vent (2), every cylinder casts out crank case vent road (4) between camshaft hole (3) and the crankcase (9), gas and oil equilibration chamber (1) separates by cooler water cavity dividing plate (6) and cooler water cavity (5), and gas and oil equilibration chamber (1) separates by cylinder hole water intake dividing plate (7) and cylinder hole water intake (8).Oil gas trend in the crankcase (9) is: crankcase (9) → crank case vent road (4) → camshaft hole (3) → balance cylinder's air vent (2) → gas and oil equilibration chamber (1), oil gas finally reaches pressure balance in gas and oil equilibration chamber (1).
Claims (1)
1, a kind of cylinder of diesel engine gas and oil equilibration cell structure, comprise gas and oil equilibration chamber, balance cylinder's air vent, camshaft hole, crank case vent road, cooler water cavity, cooler water cavity dividing plate, cylinder hole water intake dividing plate, cylinder hole water intake, crankcase, tappet hole, the top that it is characterized in that tappet hole (10) is provided with gas and oil equilibration chamber (1), the side in tappet hole (10) is provided with balance cylinder's air vent (2), is provided with crank case vent road (4) between camshaft hole (3) and the crankcase (9).
