What component collects and directs burned gases in the exhaust system?

The exhaust manifold is a critical component of the exhaust system that collects burned gases from the engine's cylinders and directs them into the exhaust system. It is typically located on the engine’s cylinder head and is designed to channel the exhaust gases efficiently away from the engine to prevent back pressure that could hinder engine performance. The design of the exhaust manifold plays a vital role in the overall efficiency of the exhaust system, helping to streamline the flow of gases and thereby improving engine output and response.

Other components listed, such as the muffler, turbocharger, and radiator, serve different purposes. The muffler’s main function is to reduce the noise produced by the exhaust gases as they exit the vehicle. The turbocharger uses exhaust gases to increase engine power by forcing more air into the combustion chamber. The radiator, on the other hand, is part of the cooling system and helps maintain optimal engine temperature rather than managing exhaust gases. Thus, the exhaust manifold is uniquely responsible for collecting and directing burned gases.
