JSAE 2006

-Next Generation Engine Intake and Exhaust System Applications
-New engine intake and exhaust system has been developed by adopting existing devices such as turbo actuators and reed valves for EGR system.

-Reed Valve for EGR System: It is possible to flow exhaust gases only in one direction from the exhaust side to the intake side, reducing  NOx emissions substantially
-Variable Nozzle Actuator: The angle of a nozzle vane of a variable wing turbocharger can be controlled.
-Waste Gate Actuator: This actuator controls opening and closing of a waste gate valve so that turbo pressure of a turbocharger may not rise to a dangerous level. 
-Chromium-free Material for Cylinder Head Gaskets (Photo)
-Chrome-free materials have been developed to meet EU regulations.
-Either pre-coating or screen coating is applicable depending on the customer's needs.
-New FKM O-rings(Photo)
-Entirely new fluorocarbon rubber O-rings that have higher low temperature resistance than previous fluorocarbon rubber materials, which can withstand up to nearly minus 50 degrees Celsius. Products are under development for delivery.
-Excellent low temperature resistance.
-Oil Seal(Photo)
-Low friction by small X-section (Cross section) seal lip
-Compact design (6X6mm) compared with conventional seals
-Seal Ring for AT & CVT Rotation(Photo)
-A T-shaped surface of the seal ring cross section has reduced pushing load against the opposite surface, and a special step cut pattern has reduced leaking amount. Both stable low leakage and low torque have been achieved.
