Manifold pressure, temperature and density of the air, and engine speed are all considered by the computer before it calculates the correct amount of fuel to inject into the cylinders.

Question

Quizplus · Accepted Answer

Modern fuel injection systems in vehicles use a computer (ECU - Engine Control Unit) that takes into account various parameters such as manifold pressure, air temperature, air density, and engine speed to calculate the precise amount of fuel to inject into the cylinders for optimal combustion and efficiency.
