A Doodle Takes the Lead | What's in the "Small Schoolbag" of the Fourth Doosan Model?

The Fourth National Emission Standard will be fully implemented soon

You with eyes like torches

You can tell at a glance from a distance.

Is there a difference between the third and fourth models?？

Press“Standard”Regulation

Power at 37kW-560kWYes

Non-road mobile machinery and equipment of the fourth national standard

Particulate traps shall be installed（DPF）

That's our main character today.“Small schoolbag”

Let's take a look.

The fourth national model“Small schoolbag”Medium

What exactly is there“Mystery”

↓↓↓

If you open it curiously“Small schoolbag”

You will find particle traps.（DPF）

Inside is a filter with ceramic as the main body.

How it works.

It is a filtering device through surface and internal mixing.

“Hold on”Particulate matter in emissions

Uch as diffusion precipitation、Inertial sedimentation or linear interception, etc.

Don't underestimate this guy.

It effectively purifies 70%-90%Emissions of particles

Reduce the generation of harmful tail gas

So here's the problem again.

As working hours increase

More and more harmful particles will be captured.

Will lead toDPFThe internal pressure increases.

At this time, the regeneration function is needed.

The regeneration function may

Harmful in tail gas、PMLarge particle interception

And high temperature“Cremation”

Make the exhaust gas comply with the regulations、Reduce pollution

With Doosan Excavator, the fourth new machine of the country

DX150W-Take 10 as an example

With the new 6-cylinder engine

And post-processing system“Small schoolbag”A combination of

Not only in terms of power and fuel economy

Easier to reduceNOx(Nitrogen oxides)、

HC(Hydrocarbon)、PM(Carbon、Ash and other particles)

Discharge of harmful substances

PMEmissions can be reduced by 90%Above！

It is worth mentioning that

This system also supports

Active regeneration and manual regeneration function

Active regeneration function approximately every 60 hours

It can be completed in about half an hour.

Manual regeneration function

Complete in about 40 minutes

How's it going？

The back of the original fourth national model.“Small schoolbag”Li

There are so many mysteries.

However, in the face of the fourth national emission standards,

Face manual、Active regeneration

There's no need to panic.

The Doosan Excavator is ready for everyone.

Modern Doosan Construction Machinery

It is not only the first one to pass the approval of the Fourth National Environmental Protection Standard.

Foreign-funded construction machinery enterprise

More before the launch of the product

After the single machine 4000+Hours of rigorous testing

And repeated calibration verification

The fourth era of the country，Strive to be the first

Choose the fourth national model

Just keep using the Doosan Excavator.！
