Jiangsu Changzhou Bost Fuel Injection Equipment Co., Ltd. was
founded in 1990. We specialize in manufacturing diesel fuel
injection spare parts, such as nozzles, elements / plungers,
delivery valves and injection pump assembly. We have a high
reputation in the field. Our company covers an area of 20000 square
meters, with more than 400 persons.
Currently, we have three series of products, that are S, J and P,
and more than 1000 kinds of injection nozzles. Our market share
conquers 40% of the domestic market with medium price and super
quality. And part of them are exported to the Middle East, Europe
and the United States. Based on the first-class equipment, testing
instruments and technology, we can assure our products of specility
and high-quality. At present, we are developing diesel fuel
injectors and have gained ground-breaking results.
In 2004, we passed the certification of ISO9001:2000. Our products
are satisfied by our clients and hold a safe lead in this field. We
have gained 6 science and technology patents. In 2008, we
independently developed high-end production equipment: CNC
8-position end face and mirror automaticly grinder which has online
automatic measurment function. We are the pioneer in this field.
The research result has filled up the blank of the country and
achieve the advanced level in the world. In 2009, we independently
developed special cylindrical grinder for grinding three-conical
surface of needle and special CNC Grinding Machine with the
function of measuring the line pressure at injector side and nozzle
needle lift. They have obtained national patents.
Our company adpots honing technology which can enhance the abrasion
resistance of middle hole of the needle valve body. In order to
ensure all kinds of products are consistent, we adopt three-conical
surface grinder to process the seal seat of needle valve body.
Moreover, we adopt face ultra-precision grinding machine to process
the end face of needle valve body. And the pressure chamber of
needle valve body adhibits the technology of electroanalysis
deburring. Furthermore, we use high speed CNC drilling machine for
the machining of fuel spray nozzle holes. And we use advanced high
pressure honing technology in extruding and honing spray holes. In
this way, it can increase the flow coefficient of spray holes and
make the spraying more uniform, with better gas mixture and more
adequate combustion. So our products can completely meet the
requirements of different engine performance. To choose the Bost
Nozzle is to choose Original power, Original quality and Original
fuel consumption.
From 2011 to 2012, our company will invest RMB50,000,000 to produce
high-pressure common-rail fuel injectors which can meet emission
standard of EuroIV and EuroV. Bost Company insists on the working
philosophy of "pursuing for first-rate quality, living by
innovation". We make an effort to own a common green homeland. Bost
lets the sky bluer and water more beautiful.
Bost is more trustworthy, because of our specialization.
