Abstract
The utility model relates to a direct-injection inlet channel for a 195 diesel, which belongs to the technical field of the internal combustion engine. The inlet channel of the existing product having the same model with the utility model has the defects that the dimensional design is unreasonable, and the shape adopted in the inlet channel is not ideal, making the flow resistance of gases large, the produced vortex intensity small and the fuel oil consumption rate of the diesel enhanced. The utility model has the technical scheme that the distance h1 from a boss of a valve guide pipe to the bottom plane of a cylinder cover is 35 mm; the diameter phi 2 of an inlet port is 45 mm; the distance h2 from the center of the inlet port to the bottom plane of the cylinder cover is 48 mm; the distance h3 from the center of a valve seat ring to the end surface of the inlet port is 51.1 mm; the diameter phi 1 of an outlet port is 39.5 mm. The utility model has the advantages that because the structural dimension is utilized, and the inlet channel adopts a spiral inlet channel, the flow resistance is small, the vortex intensity is large, and stable vortex can be formed, making the shape of a combustion chamber matched with that of an oil bundle; air is centralized near the oil bundle, and the air in the combustion chamber can be better utilized, making the fuel oil consumption rate lower.
Description
Technical field: the utility model relates to technical field of internal combustion engines, is a kind of 195 diesel engine direct injection intake ducts more specifically.
Background technique: the intake duct size design of same model product is unreasonable now, and the undesirable gas flow resistance that makes of shape that intake duct adopts is big, and the strength of vortex of generation makes the fuel consumption rate of diesel engine improve for a short time.
Summary of the invention: for overcoming above-mentioned shortcoming, the purpose of this utility model is a kind of 195 diesel engine direct injection intake ducts of design.Its technological scheme is: 1 is 35mm from the valve guide bushing boss to cylinder head bottom plane distance h, suction port diameter of phi 2 is 45mm, is 48mm from the suction port center to cylinder head bottom plane distance h 2, is 51.5mm from the air valve seat ring center to suction port end face distance h3, and air outlet diameter of phi 1 is 39.5mm.The advantage of this model utility is: the reasonable in design practicality, the novelty that is skillfully constructed is utilized this kind physical dimension, in the limited position of cylinder head, intake duct adopts spiral inlet duct, it is little that it has flow resistance, and the advantage that strength of vortex is big utilizes 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 makes fuel consumption rate lower.
Description of drawings: Fig. 1 plan view, Fig. 2 plan view.
Embodiment: is 35mm from the valve guide bushing boss to cylinder head bottom plane distance h 1, suction port diameter of phi 2 is 45mm, is 48mm from the suction port center to cylinder head bottom plane distance h 2, is 51.5mm from the air valve seat ring center to suction port end face distance h3, and air outlet diameter of phi 1 is 39.5mm.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 makes fuel consumption rate lower.
