A thermally stable component formed of a tempered aluminum alloy casting which reduced costs is provided. The aluminum alloy typically has an elongation of at least 8% after casting, which is preferred for self-piercing rivet processes. The aluminum alloy leaves a casting facility in the as-cast (F temper) condition.

The artificial aging process typically includes electrodeposition coating and curing. The components that can be formed by the reduced cost method include lightweight automotive vehicle components, including structural, body-in-white, suspension, or chassis components, such as front shock towers, front body hinge pillars, tunnels, and rear rails.

A regenerative power generation device uses engine exhaust gas to spin a turbine to generate electricity, improving a vehicle's fuel efficiency. Solution: Exhaust gas is generally about 800 degrees, so its specific heat will damage the belt and generator 19. Therefore, by utilizing the turbine engine invented previously, the turbine is rotated at a temperature of about 60 degrees to prevent problems from occurring, and the problem is solved. For example, in a 660cc turbine engine for a light vehicle, the turbine has an outer diameter of 74cm, an inner diameter of 68cm, and a thickness of 2.9cm, the area through which the combustion gas passes is 3cm wide and 9mm thick, and the combustion chamber volume is 25cc. If the power is generated only by the regenerative power generation device and the turbine engine is used only for driving, the vehicle is expected to travel 200km on the highway per 1L of regular gasoline. Since 100% of the electricity used is generated only by the regenerative power generation device, the estimated fuel efficiency is expected to improve by 20% to 30%.
