The ISUZU
4HK1 fuel injector is one of the precise parts of the 4HK1 diesel
engine. The injector is particularly vulnerable to get damage due to wear and
overpressure. The 4hk1 engine is the widely use of in Case, Hitachi and other
machinery equipment, which is in particularly large demand. Because of the
demand, the fuel injectors in the market will pass away the sham as the
genuine. We need to pay special attention to the following tips when we
buy 4HK1
fuel injectors of ISUZU engine parts.
1.Original or Refurbished?
The 4hk1 injectors are generally from
ISUZU and Denso factor y. If you buy it from the original agent in low
quantity, the injectors from both would be particularly expensive. But there
are refurbished injectors. So the original and the refurbished products coexist
at the same time in the market. Before your payment, you should think carefully
and make a choice, buy the original or the refurbished injector.
2. Is the refurbished injector in bad
quality?
In general, the quality of refurbished
products will be relatively lower compared with the original products. But in
fact, the work life of a refurbished injector will last about 80 to 90 percent
of the original one. If the refurbished manufacturer’s production technique
meets the original requirements, it is generally possible that the refurbished
injector can achieve standard quality.
3.Package can trick you.
Although we mentioned that manufacturers
with better manufacturing technique would be able to bring the refurbished
injectors up to standard quality. However, because of different manufacturers,
the quality of injectors is uneven. And it is a great damage to the interests
of customers that many refurbished injectors are originally packaged and in the
market. Therefore, it is necessary to cooperate with big brand suppliers in
long-term relationship.
4. Are 4HK1 Fuel Injector and 6HK1 Fuel
Injector in common use?
Yes, the
fuel injectors of the 4HK1 and the 6HK1 engines are in common use.
5. Please pay attention to the item
number.
As we said above, both ISUZU and Denso
suppliers provide 4HK1 fuel injectors, but there are many parts numbers of
them. The parts number of Isuzu fuel injector is like x-xxxxxxxx-x, and the
parts number of Denso fuel injector is xxxxxx-xxxx. During purchasing, it is
necessary to make sure the corresponding part number in order to buy product of
correct part number.
6. Can I exchange the old broken
injector with the new one?
SINOCMP provides replacement activities for
old injectors. We will make quotations based on the quality of the injectors we
received. We accept the old broken injector in exchange for the refurbished
one. But the original injector will not participate in the exchange activity.
7. Do I need to embed the code with ID?
The pure original parts have the code
setting, which aims to make ID code information recognized and learned by ECU,
and then accurately master injection flow of fuel injector and other specific
parameters, so as to achieve accurate matching effect. That is done from a
professional perspective, which requires a series of detection equipment
setting. However, the original injector and ECM will be self-matching during
installation, which aims to master the appropriate injection state. So we do
not need to set the ID code. The fuel injector also can be installed and used
directly because original injector factory will make the fuel injector set for
calibration to ensure that it can be used.
Special tips: The electric fuel injector
has higher requirements on oil. So we should use fuel oil in good quality; Fuel
filters must also be checked and replaced regularly to avoid clogging the oil
circuit with impurities and affecting the precision of the injector.
