Questions: Analice la gráfica de combustión y explique la importancia que tiene el "punto de inyección" en el retraso del encendido (Fase 1)

Solution Steps

The graph shows the pressure (p) in bars versus the crank angle (α) in degrees. It illustrates the combustion process in an internal combustion engine, divided into three phases: Fase 1, Fase 2, and Fase 3. Points A, B, C, and D mark significant events in the combustion process.

• Fase 1 (Ignition Delay): This phase starts at the injection point and ends at point B. It represents the delay between fuel injection and the start of combustion.
• Fase 2 (Combustion): This phase starts at point B and ends at point C. It represents the rapid combustion of the fuel.
• Fase 3 (Expansion): This phase starts at point C and ends at point D. It represents the expansion of gases after combustion.

The "punto de inyección" (injection point) is crucial in determining the ignition delay (Fase 1). The timing of fuel injection affects the pressure rise and the efficiency of combustion. A well-timed injection ensures optimal combustion, reducing fuel consumption and emissions.
