What causes excessive absolute pressure in the Hyundai ix35 intake manifold?

[DeJake]

Excessive absolute pressure in the Hyundai ix35 intake manifold can be caused by the following reasons: 1. Throttle opening: The smaller the throttle opening, the greater the suction effect created by the piston during intake, resulting in higher intake manifold suction, greater vacuum, and consequently lower intake manifold pressure (the intake manifold suction is opposite to its current suction). 2. Engine speed: The higher the engine speed, the greater the suction effect created by the piston during intake, resulting in higher intake manifold suction, greater vacuum, and consequently lower intake manifold pressure. 3. Sealing performance: This includes the sealing performance of both the intake manifold and the cylinders. Better sealing performance leads to higher intake manifold suction, greater vacuum, and consequently lower intake manifold pressure.
