Abstract
The utility model relates to a direct-injection 192 piston combustion chamber structure, and belongs to the technical field of an internal-combustion engine. The vortex flow formed in existing combustion chamber for products with the same size is unstable, and the match of oil stream is bad, so that the oil fuel consumption of a diesel engine is high. The utility model has the technical scheme that the depth h1 of the combustion chamber is 14.5mm; the bulge depth h2 of the combustion chamber is 10mm; the eccentricity t1 is 5mm; the eccentricity t2 is 2.5mm; the diameter phi 1 of the combustion chamber is 49.5mm; the diameter phi 2 of the combustion chamber is 30mm; the circular arc R of the combustion chamber is 5mm. The utility model has the advantages of reasonable and practical structural design and skillful and original design. The utility model with the structure size can form stable vortex flow, cause the shape of the combustion chamber to be matched with the oil stream, and concentrate air near the oil stream, so that the air in the combustion chamber can be well utilized. The fuel consumption is low. The utility model saves energy resources and is a product with energy saving and environmental protection.
Description
Technical field: the utility model relates to technical field of internal combustion engines, is a kind of straight spray 192 piston combustion cell structures more specifically.
Background technique: the firing chamber of present same model product is because design size is unreasonable, and the eddy current that forms in the firing chamber is unstable and oily Shu Peihe is bad, makes the diesel engine fuel consumption height.
Summary of the invention: for overcoming above-mentioned shortcoming, the purpose of this utility model is a kind of straight spray 192 piston combustion cell structures of design.Its technological scheme is: combustion-chamber depth h1 is 14.5mm, and firing chamber projection degree of depth h2 is 10mm, and degree of eccentricity t1 is 5mm, and degree of eccentricity t2 is 2.5mm, and firing chamber diameter of phi 1 is 49.5mm, and firing chamber diameter of phi 2 is 30mm, and the firing chamber circular arc R is 5mm.The advantage of this model utility is: the reasonable in design practicality, and the novelty that is skillfully constructed is utilized this kind physical dimension, can form stable eddy current, make combustion-chamber shape and oily Shu Peihe, air is concentrated near the oil bundle, but the air in the better utilization firing chamber, fuel consumption rate is lower, in today that petroleum resources growing tension, oil price remain high, low fuel consumption rate can embody the market advantage, obtains user's welcome, its energy saving is the energy-conserving and environment-protective products.
Description of drawings: Fig. 1 plan view, Fig. 2 plan view.
Embodiment:: combustion-chamber depth h1 is 14.5mm, and firing chamber projection degree of depth h2 is 10mm, and degree of eccentricity t1 is 5mm, and degree of eccentricity t2 is 2.5mm, and firing chamber diameter of phi 1 is 49.5mm, and firing chamber diameter of phi 2 is 30mm, and the firing chamber circular arc R is 5mm.Utilize this kind physical dimension, can form stable eddy current, make combustion-chamber shape and oily Shu Peihe, air is concentrated near the oil bundle, but the air in the better utilization firing chamber, and fuel consumption rate is lower.
