-Fuel Cooler
-Due to a thin-type and compact size, this fuel cooler can be installed on a one-ton pickup with a limited space.
-It is installed on the Isuzu "D-MAX" in Thailand and produced locally.
<Line up>
Compact type (Steel and aluminum), Fin-tube type (Steel) and Extended tube type. (ULLT)
-ECFD: Externally Controlled Fan Drive <Filing for patent>
-A valve is opened or closed by the magnetic coil in accordance with signals from the external control unit (ECU) to control freely the number of a fan rotation.
-Electrical control of a valve can provide a more speedy response than a conventional bimetal coupling,
-Optimal control of a valve improves fuel consumption, acceleration and noise level.
-Delivered to a Ford SUV.
-UFRID: Fuel Rail with Damping Effect <Filing for patent>
<Features>
-Noise reduction in the cabin; Fuel pressure pulsation is reduced and abnormal pulsation noise coming out of fuel tubes can be controlled..
-Cost and weight reduction; Other noise absorbing devices such as pulsation dampers and fuel tube damper clippers can be eliminated.
-Stabilized air-fuel ratio; Improvement in air-fuel performance is expected because fuel pressure pulsation can be reduced in main tubes.
<Effects>
*Test vehicle; 4-cyliner 1,000 cc engine
Test condition; During idling
-USIT-SP( High Pressure Fuel Injection Tube <Filing for patent>
-Fuel injection tube suitable for a high pressure diesel engine, especially with a common rail system.
-Single layered steel tube made of high tensile steel equivalent to EN E355.
-Used by major domestic truck manufacturers.
EUSIT-SP VS1A (Designed for inner pressure below 160 MPa):
-This tube has an excellent cleaning performance in the inner pipe surface capable of eliminating a foreign metal particle under 150m.
EUSIT-SP VS1H (Designed for inner pressure of 160MPa and 180MP):
-This tube uses higher tensile steel than the current USIT-SP VS1A, increasing inner pressure fatigue strength.
EUSIT-USP VS1H (Designed for inner pressure 180MPa and,200MPa):
-Application of special treatment to the inner surface has increased inner fatigue strength. (At the preparing stage for production)
-Due to a thin-type and compact size, this fuel cooler can be installed on a one-ton pickup with a limited space.
-It is installed on the Isuzu "D-MAX" in Thailand and produced locally.
