The inside has achieved an extremely high level of cleanliness.
USIT-SP is the world's first fuel injection pipe adopted for common rail fuel injection systems that are effective in reducing diesel engine exhaust emissions. Since then, to support the advancement of diesel engine technology, Usui International Industry Co., Ltd. has utilized its unique plastic processing technology, heat treatment technology, and inner surface smoothing technology to consistently achieve the world's highest level of pressure resistance. At the same time, we have developed cleaning technology that reduces foreign substances inside the pipe, achieving an extremely high level of cleanliness. 【Features】 ○ Highly regarded and installed in more than half of the common rail diesel engines produced worldwide. ○ To respond to the strengthening of future exhaust gas regulations, the current fuel injection pressure of around 200 MPa is expected to increase further. ○ Development of fuel injection pipes compatible with common rail injection systems exceeding 250 MPa has been completed.
