Abstract
The utility model relates to a diesel engine with cylinders that is capable of limiting the piston stroke and decreasing the engine height and includes cylinders, cylinder sleeves, pitons, braces, connecting rods and other spare parts; wherein, the inner diameter of the wet cylinder sleeved inserted inside cylinder holes is 103mm to 107mm; the central distance between two nearby cylinder is 125mm to 129mm. Through decreasing the piston stroke of the diesel engine to 118mm to 120mm from 123mm to 127mm, the piston compressing height and the central distance of connecting rods is reduced, thus the rotating speed of the diesel engine is increased, the height of the diesel engine is decreased, and the matched suitable scope of the diesel engine is enlarged.
Description
(1) technical field:
The utility model belongs to field of internal combustion engine, relates to a kind of multi-cylinder diesel engine that limits stroke of piston and reduce the body height.
(2) background technique:
At present, the way that China's internal-combustion engine industry (particularly agricultural engine industry) is extensive use of ease off improves the rotating speed of diesel engine and reduces the body height, to adapt to the supporting requirement of vehicular engine, increases the supporting accommodation of diesel engine.But most of producer only depends on the way that shortens stroke of piston to solve, so the reduction of body height is limited, is difficult to satisfy the supporting requirement of main frame.
(3) summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, under the situation that limits adjacent cylinder centre distance, simultaneously stroke of piston is defined as 118mm ± 2mm also can be reduced to the body height 313.5mm ± 2mm by 340mm ± 2mm wet cylinder liner multi-cylinder diesel engine.
The utility model adopts following technological scheme to realize above-mentioned purpose: the stroke of piston of diesel engine is defined as 118mm ± 2mm, bore spacing is defined as 127mm ± 2mm, insert wet liner in this cylinder block cylinder-bore, the internal diameter of its cylinder liner are Φ 105mm ± 2mm.Center, piston Xiao hole in the piston details is reduced to 62.5mm ± 2mm to the distance (being piston compression height) of piston combustion bowl end face by 67.5mm ± 2mm, simultaneously crankshaft of diesel engine connecting rod turning radius is decreased to 59mm ± 2mm by 62.5mm ± 2mm, connecting rod CONCENTRIC REDUCER center hole distance is decreased to 192mm ± 2mm by 210mm ± 2mm, thereby realized under the prerequisite that does not change the cylinder block processing technology, the diesel engine piston stroke is reduced to 118mm ± 2mm by 125mm ± 2mm, and the body height is reduced to 313.5mm ± 2mm by 340mm ± 2mm.
The utility model can reach following good effect:
1, limiting diesel engine piston stroke and adjacent cylinder centre distance and do not changing under the prerequisite of cylinder block parts machining process, realized that the diesel engine piston stroke is reduced to 118mm ± 2mm by 125mm ± 2mm, and the body height has been reduced to 313.5mm ± 2mm by 340mm ± 2mm.Thereby can improve the rotating speed of diesel engine, and reduce the body height of diesel engine significantly.Provide a kind of mentality of designing of innovation with rotating speed that increases diesel engine and the complete machine height that reduces diesel engine for reducing the diesel engine piston stroke.
2, the stroke of this diesel engine is reduced to 118mm ± 2mm and has been reduced the body height by 125mm ± 2mm after, reduced mean piston speed, improved the body rigidity, reduced the vibration of diesel engine, the rotating speed of diesel engine can be improved a lot, the complete machine height is reduced, to satisfy the supporting requirement of diesel engine for automobile, make the utility model reach the raising diesel engine speed, enlarge the requirement of supporting accommodation.
(4) description of drawings: Fig. 1 is a structural representation of the present utility model.
(5) embodiment:
The stroke of piston of diesel engine is defined as 118mm ± 2mm, and adjacent cylinder centre distance is defined as 127mm ± 2mm, insert wet liner 2 in this cylinder block 1 cylinder-bore, and the internal diameter of its cylinder liner is Φ 105mm ± 2mm; Center, piston Xiao hole in the piston 3 is reduced to 62.5mm ± 2mm to the distance H (being piston compression height) of piston combustion bowl end face by 67.5mm ± 2mm, connecting rod 5 turning radius R with crankshaft of diesel engine 6 are decreased to 59mm ± 2mm by 62.5mm ± 2mm simultaneously, the CONCENTRIC REDUCER center hole of connecting rod 5 is decreased to 192mm ± 2mm apart from L by 210mm ± 2mm, thereby be implemented under the prerequisite that does not change the cylinder block processing technology, the diesel engine stroke is decreased to 118mm ± 2mm by 125mm ± 2mm, and the body height A is reduced to 313.5mm ± 2mm by 340mm ± 2mm.
