- At Mitsubishi Motors, a thin-walled exhaust manifold, made of stainless cast-steel, has been developed with the aim of achieving higher heat-resisting reliability as well as weight reduction. The new exhaust manifold is made of ferritic stainless cast-steel, employing an advanced vacuum casting (CLAS). Its geometry was designed using finite element analysis and its durability was confirmed by testing both on various test devices and on a vehicle.The exhaust manifolds has been adopted on a production engine model and has proven the following advantages over a conventional cast-iron ones;
-
excellent heat resistance. weight reduction of over 20%.
-
possible exhaust emission reduction as a result of lower heat-capacity of the exhaust manifold.
