Fuel

 

consumption

 

The

 

content

 

of

 

diesel

 

plays

 

a

 

very

 

critical

 

role

 

in

 

diesel

 

engine’s

 

performance,

 

life

 

expectancy

 

and

 

the

 

content

 

of

 

discharged

 

material.

 

In

 

order

 

to

 

achieve

 

the

 

rated

 

power,

 

fuel

 

economy

 

and

 

specified

 

emission

 

standard,

 

only

 

the

 

fuel

 

which

 

refer

 

to

 

international

 

standard

 

or

 

national

 

standard

 

can

 

be

 

used.

 

The

 

parameters

 

of

 

diesel

 

fuel

 

include

 

low

 

temperature

 

feature,

 

sulphur

 

content,

 

specific

 

gravity,

 

water

 

content

 

and

 

foreign

 

material

 

content

 

shall

 

be

 

the

 

first

 

priority

 

when

 

user

 

need

 

to

 

choose

 

the

 

quality

 

of

 

the

 

fuel.

 

Different

 

quality

 

of

 

fuel

 

will

 

directly

 

affect

 

diesel

 

generator

 

set’s

 

start,

 

lubricating,

 

output

 

power,

 

discharge,

 

and

 

fuel

 

filter

 

change

 

cycle

 

etc.

 

Specific

 

requirement

 

for

 

fuel

 

please

 

refer

 

to

 

engine

 

operation

 

manual

 

which

 

attached

 

with

 

the

 

generator

 

set.

 

Warning:

 

!

 

When

 

you

 

intend

 

to

 

add

 

fuel

 

into

 

the

 

fuel

 

tank,

 

please

 

make

 

sure

 

the

 

generator

 

set

 

has

 

been

 

stopped.

 

Only

 

after

 

the

 

added

 

fuel

 

become

 

static

 

for

 

some

 

time,

 

this

 

generator

 

set

 

can

 

be

 

started

 

again.

 

This

 

way

 

to

 

avoid

 

the

 

foreign

 

material

 

in

 

the

 

diesel

 

fuel

 

being

 

sucked

 

to

 

fuel

 

supply

 

hose,

 

which

 

will

 

cause

 

fuel

 

filter

 

stuck

 

and

 

fail

 

to

 

supply

 

engine

 

with

 

sufficient

 

fuel,

 

and

 

in

 

turn

 

decrease

 

the

 

output

 

power.

 

!

 

The

 

malfunction

 

caused

 

by

 

bad

 

quality

 

of

 

fuel

 

does

 

not

 

belong

 

to

 

the

 

scope

 

of

Battery

 

Our

 

generator

 

set

 

standard

 

configuration

 

provides

 

start

 

battery

 

as

 

accessory

 

parts.

 

According

 

to

 

user’s

 

different

 

requirements,

 

our

 

company

 

can

 

provide

 

two

 

types

 

of

 

batteries,

 

that

 

is

 

high

 

efficient

 

plumbous

 

acid

 

battery

 

and

 

maintenance

 

free

 

battery.

 

If

 

maintenance

 

free

 

battery

 

is

 

used,

 

users

 

only

 

need

 

to

 

connect

 

cables

 

for

 

the

 

battery.

 

If

 

plumbous

 

acid

 

battery

 

is

 

used,

 

before

 

being

 

used,

 

users

 

need

 

to

 

use

 

standard

 

battery

 

to

 

electrolyze

 

primary

 

liquid.

 

Untighten

 

the

 

battery

 

cover,

 

slowly

 

pour

 

electrolyte

 

into

 

the

 

battery

 

until

 

the

 

electrolyte

 

level

 

reach

 

the

 

indicating

 

line

 

in

 

the

 

internal

 

polar

 

plates(not

 

allow

 

to

 

exceed

 

this

 

line),

 

then

 

take

 

off

 

the

 

lable

 

from

 

the

 

battery

 

cover’s

 

air

 

hole

 

and

 

close

 

the

 

cover.

 

After

 

the

 

electrolyte

 

being

 

added,

 

please

 

don’t

 

use

 

it

 

immediately,

 

keep

 

the

 

battery

 

in

 

static

 

status

 

for

 

thirty

 

to

 

sixty

 

minutes.

 

In

 

low

 

temperature

 

environment,

 

this

 

time

 

period

 

need

 

to

 

be

 

extended

 

(use

 

battery

 

charger

 

to

 

charge

 

battery

 

when

 

necessary)

 

Users

 

can

 

use

 

the

 

standard

 

connecting

 

cable

 

attached

 

with

 

the

 

generator

 

set,

 

the

 

red

 

color

 

shall

 

be

 

connected

 

to

 

positive

 

polar,

 

black

 

(or

 

blue)

 

to

 

negative

 

polar,

 

correctly

 

connect

 

to

 

the

 

generator

 

set’s

 

start

 

motor

 

.

 

Most

 

of

 

the

 

diesel

 

generator

 

sets’

 

cables

 

have

 

been

 

connected

 

to

 

the

 

engines

 

before

 

shipment.

   

The

 

energy

 

storage

 

capacity

 

of

 

the

 

start

 

battery

 

will

 

determine

 

if

 

the

 

diesel

 

engine

 

generator

 

set

 

can

 

smoothly

 

start

 

in

 

a

 

specified

 

period.

 

During

 

the

 

process

 

of

 

generator

 

sets

 

running,

 

the

 

charging

 

alternator

 

installed

 

in

 

the

 

engine

 

will

 

continuously

 

charge

 

battery

 

to

 

start

 

battery.

 

Warning:

 

!

 

Please

 

ensure

 

the

 

connection

 

for

 

positive

 

and

 

negative

 

polar

 

is

 

correct.

 

Wrong

 

connection

 

will

 

cause

 

malfunction!

 

(Wrong

 

connection

 

will

 

surely

 

cause

 

damage

 

to

 

the

 

charging

 

alternator)

 

!

 

When

 

generator

 

set

 

is

 

running,

 

battery

 

cables

 

are

 

not

 

allowed

 

to

 

be

 

cut

 

down!
