Description
Technical field
The utility model is related to technical field of engines, especially a kind of double-cylinder V-shape Diesel engine.
Background technology
At present, country carries out non-rice habitats diesel engine state III, the emission request of state IV, drops low exhaust gas emission, improves air quality.
Emission control is required diesel engine, and two cylinder V-type vortex diesel engine discharge capacity 1L, power≤18kW, technology path uses automatically controlled monomer
Pump+axial needle type injector+minor air cell combustion chamber, can effectively reduce discharge, reach the requirement of state III.The two cylinders V-type vortex diesel engine
The monomer pump configuration of use is also V-structure, and the oil inlet pipe of diesel engine is different with oil return pipe pipeline arrangement to diesel engine
Performance impact is very big.In traditional design, oil inlet pipe and two cylinders use series system, and diesel oil enters two cylinder oil pump electricity from fuel inlet fitting
Magnet valve fuel feeding, then enter a cylinder oil pump magnetic valve fuel feeding from two cylinder oil pump magnetic valve by oil inlet pipe, finally by return line
Arrival oil return solenoid valve returns to back leakage connection and enters fuel tank, but such series system has two oil supply cylinders inequality, causes hair
The phenomenons such as the cylinder power of motivation two is uneven, the warm inequality of row, rotary speed unstabilization.
The content of the invention
The purpose of this utility model is that oil inlet pipe and oil return pipe pipeline arrangement in order to solve traditional diesel engine use string
Connection mode, the problem of uneven cylinder power of engine two, the warm inequality of row, rotary speed unstabilization etc. can be caused.
In order to solve problem above, the utility model provides a kind of double-cylinder V-shape Diesel engine, including casing, described
Casing is provided with in-line, and the in-line is divided into return line, a cylinder in-line and two cylinder in-line, a cylinder
In-line is provided with a cylinder oil pump magnetic valve and connects a cylinder oil inlet, and the two cylinder in-line is provided with two cylinder oil pump electricity
Magnet valve simultaneously connects two cylinder oil inlet, and the return line connects back leakage connection by oil return solenoid valve.After two cylinders are in parallel, enter
Two cylinder diesel oil are identical, and quite, engine speed is more steady for the cylinder power of engine two, row's temperature, oil consumption.So two cylinder V-type diesels are electric
Control monoblock pump uses parallel pipeline.Unnecessary oil can also return to fuel tank by return line, save the energy.
Preferably, the cross-sectional area of the in-line is more than a cylinder in-line and two cylinder in-line.Pipeline
Cross-sectional area has after difference, and a cylinder and two cylinder can have sufficient oil pressure, so as to obtain sufficient oil-feed.
Preferably, the return line is provided with pressure valve.Return line is provided with after pressure valve, can guarantee that foot
Enough oil is into a cylinder and two cylinder, and unnecessary ability is returned in fuel tank from return line, it is ensured that two cylinder working fuel deliveries.
The utility model uses parallel way so that identical into two cylinder diesel oil, the cylinder power of engine two, row's temperature, oil consumption
Quite, engine speed is more steady.
The utility model is through using proof, effect is preferable, simple and practical.

Embodiment
A kind of double-cylinder V-shape Diesel engine of the utility model is described further below in conjunction with the accompanying drawings.
As shown in fig. 1, the utility model provides a kind of double-cylinder V-shape Diesel engine, including casing 1, the casing 1
Provided with in-line 2, the in-line 2 is divided into return line 5, a cylinder in-line and two cylinder in-line, the oil-feed
The cross-sectional area of pipeline 2 is more than a cylinder in-line and two cylinder in-line.Line cross section area has after difference, a cylinder and
Two cylinder can have sufficient oil pressure, so as to obtain sufficient oil-feed.The one cylinder in-line is provided with a cylinder oil pump magnetic valve 3 simultaneously
A cylinder oil inlet is connected, the two cylinder in-line is provided with two cylinder oil pump magnetic valve 4 and connects two cylinder oil inlet, the oil return
Pipeline 5 connects back leakage connection 7 by oil return solenoid valve 6.The return line 5 is provided with pressure valve.Return line 5 is provided with pressure
After power valve, it can guarantee that enough oil is into a cylinder and two cylinder, unnecessary ability is returned in fuel tank from return line 5,
It ensure that two cylinder working fuel deliveries.
Identical into two cylinder diesel oil after two cylinders are in parallel, the cylinder power of engine two, row's temperature, oil consumption are suitable, engine speed
It is more steady.So two cylinder V-type diesel electronically controlled unit pumps use parallel pipeline.Unnecessary oil can also return to oil by return line 5
Case, saves the energy.
The utility model uses parallel way so that identical into two cylinder diesel oil, the cylinder power of engine two, row's temperature, oil consumption
Quite, engine speed is more steady.The utility model is through using proof, effect is preferable, simple and practical.
The utility model is not limited to above example and conversion.
