Abstract
The utility model relates to a multi-cylinder diesel engine capable of limiting a body height and increasing a stroke, which comprises a diesel engine body (1). At least two wet cylinder sleeves (2) are fixed on the diesel engine body (1), a piston (3) is inserted in the wet cylinder sleeves (2), a connecting rod (5) is fixed on a pin shaft (31) of the piston (3), the pin shaft (31) is hinged on the piston (3), and a crankshaft (4) is hinged on the connecting rod (5). Since the stroke of the piston of the diesel engine is increased, the displacement of the diesel engine is increased, and the output power of the diesel engine is increased; and the requirements of small engineering machinery and agricultural machinery for high load and high power at a low speed can be satisfied. Moreover, fewer changes are adopted in the structure of the diesel engine, and design and manufacturing costs are minimized.
Description
Technical field:
The utility model relates to the diesel engine technologies field, more specifically to a kind of more powerful multiple cylinder diesel motor.
Background technique:
At present, China is Φ 90mm for small engineering machinery and farm machinery provide the cylinder bore that mostly is of mating power, piston stroke is two valves, four-stroke, water cooling, the toroidal swirl type wet liner diesel engine of 100mm, and small engineering machinery and farm machinery are power character and Economy to the basic demand of mating power.And because the power of engineering machinery and farm machinery is installed and Environmental Conditions is more special, so diesel engine structure and power are all had strict demand.And provide the power of diesel engine of power less relatively at present, the leeway of expansion is still arranged.
The model utility content:
The purpose of this utility model is exactly the deficiency at prior art, and a kind of multi-cylinder diesel engine that limits the body height and increase stroke is provided, and its piston structure helps reducing depth pistion, increases stroke, thereby improves the power of diesel engine.
Technology solution of the present utility model is as follows:
Limit the body height and increase the multi-cylinder diesel engine of stroke, comprise diesel engine body, be fixed with on the diesel engine body and be no less than two wet liners, the piston sleeve is in wet liner, connecting rod is fixed on the bearing pin on the piston, bearing pin is hinged on the piston, and bent axle is hinged on the connecting rod.
Described diesel engine body height is 275mm, and adjacent two wet liner centre distance are 112mm, and the distance of end face to the piston of the bearing pin center line on the piston is 52mm, and the turning radius of bent axle is 52.5mm.
The beneficial effects of the utility model are: owing to after the increase of diesel engine piston stroke, the discharge capacity of diesel engine is increased, thereby the diesel engine output power is increased; Can satisfy the powerful requirement of big load under the slow-speed of revolution of small engineering machinery and farm machinery.Diesel engine structural change minimum, design and manufacture cost are minimum.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Among the figure: 1, diesel engine body; 2, wet liner; 3, piston; 31, bearing pin; 4, bent axle; 5, connecting rod.
Embodiment:
Embodiment: see shown in Figure 1, limit the body height and increase the multi-cylinder diesel engine of stroke, comprise diesel engine body 1, be fixed with on the diesel engine body 1 and be no less than two wet liners 2, piston 3 sleeves are in wet liner 2, connecting rod 5 is fixed on the bearing pin 31 on the piston 3, and bearing pin 31 is hinged on the piston 3, and bent axle 4 is hinged on the connecting rod 5.
Described diesel engine body 1 highly is 275mm, and adjacent two wet liner 2 centre distance are 112mm, and the distance of end face to the piston 3 of bearing pin 31 center lines on the piston 3 is 52mm, and the turning radius of bent axle 4 is 52.5mm.
Working principle: on the bearing pin 31 on connecting rod 5 fixed pistons 3, bearing pin 31 is hinged on the piston 3, be convenient to connecting rod 5 under the situation of changing position not, be fixed together with bearing pin 31 easily, diesel engine body 1 highly is 275mm, wet liner 2 centre distance are 112mm, bearing pin 31 center lines on the piston 3 distance of end face to the piston 3 is reduced to 52mm by original 54.5mm, simultaneously the turning radius of bent axle 4 is brought up to 52.5mm by 50mm, the center hole of the CONCENTRIC REDUCER of connecting rod 5 is apart from remaining unchanged, thereby realized not changing under the prerequisite of body processing technology, the diesel engine stroke is increased to 105mm by 100mm.
