Por qué la cabina de un camión tiene dos bocinas distintas

There's a detail most drivers overlook when overtaking a truck on the highway: the position of the exhaust pipe. Some exit from the side of the cab, others point straight up. And this difference isn't accidental or a manufacturer's whim; it has a technical, economic, and even regulatory reason behind it. What it means when a truck's exhaust exits from the top instead of the side is a question few ask, but the answer reveals how large-displacement diesel engines work, how heat and gases are managed in heavy transport vehicles, and why certain countries or transport sectors prefer one configuration over the other. In this video, we break down each factor: the direction of the exhaust gases, protection from rain and dirt, the impact on cab temperature, emissions regulations, and the types of trucks that use each system. An explanation that seems minor but hides meticulously planned engineering.
