What is the function of the camshaft in a diesel engine?

The camshaft's primary function in a diesel engine is to control the opening and closing of the engine's valves. This is crucial because the precise timing of these actions ensures optimal airflow into the engine and exhaust gases out, which directly affects the engine's performance and efficiency.

In the context of German traffic rules, maintaining an optimally functioning engine is important for ensuring that vehicles meet emissions standards and operate safely. A well-functioning camshaft contributes to these aspects by ensuring that the engine runs smoothly and efficiently, which aligns with regulations aimed at minimizing environmental impact and ensuring road safety. Understanding the full functionality of engine components is essential for vehicle maintenance and compliance with German traffic laws.
