The reduction of fuel consumption is the main target for the automotive industry. The use of lightweight materials can help to reduce vehicle weight and improve fuel economy. The development of Al-Si alloy and its based material for engine application is investigated in this article, focusing on improving the material’s properties, specially fatigue limit and wear resistance, which are important properties for engine block materials. The article introduces a description of the microstructure of Al-Si alloy and its effects on this material’s behavior. Some parameters to enhance these properties are discussed such as modification, grain refinement, casting methods, alloying elements, and composite production. It was found that aluminum is the ideal light-weighting material for automotive industry. Higher silicon content usually increases the wear resistance of Al-Si alloy as it increases the alloy’s hardness. Also, grain refiners and modifiers can form fine precipitates, refine grain size, modify silicon phase morphology, and reduce the effects of defects and thus can usually increase mechanical properties. Composite is another way to improve Al-Si alloy’s properties.
