Why does the Mercedes-Benz make a loud noise when starting?
1 Answers
Mercedes-Benz makes a loud noise during cold starts because the arrangement of the exhaust manifold places the catalytic converter too far back. The catalytic converter must reach a certain temperature to effectively filter exhaust gases. Therefore, to quickly heat up the catalytic converter, the exhaust valve closure is intentionally delayed during cold starts, causing the air-fuel mixture to enter the exhaust manifold and combust, resulting in the loud noise during cold starts. Here is some related information: History of Mercedes-Benz: Mercedes-Benz was founded in 1926 by Karl Benz and Gottlieb Daimler. Its predecessors were the Benz & Cie. and Daimler-Motoren-Gesellschaft, established in 1886. The two companies merged in 1926 to form Daimler-Benz AG. Mercedes-Benz Logo: The Mercedes-Benz logo is a three-pointed star, symbolizing the ambition to dominate land, sea, and air. This emblem was created after the merger of Daimler and Benz. The original Daimler logo featured a three-pointed star, while the Benz logo had the word "BENZ" inside a double circle. After the merger, the Daimler-Benz logo became a three-pointed star inside a single circle. Making the three-pointed star shine globally has been Mercedes-Benz's dream for over a century and remains its relentless pursuit.
