The requirements of reliability verification for new products and technology are increasing more and more in accordance with the trend of climate change prevention and GHG reduction technology, functional skills. SCA(Swirl Control Actuator) is the important part of a car intake manifold system. This device generates swirl that is mixing the fuel and air into the engine combustion chamber. This is to improve output for engine and reduce the emission for exhaust. In this article reliability assessment criteria for swirl control actuator for automobiles are established in terms of basic HALT and life time test.
