In the late IVO setting, the intake valves remain closed during the initial part of the intake stroke resulting in a drop in the cylinder pressure.
Many, if not most, DI engines use a strategy that injects fuel during the intake stroke under most operating conditions.
At that point, a bigger lobe on the crankshaft engages the rockers, increasing the duration and exposure of the intake stroke, effectively increasing horsepower.
0K2, featuring Honda s EXlink (Extended Expansion Linkage Engine), featuring an expansion stroke longer than its intake stroke, resulting in a high expansion ratio for greatly increased thermal and fuel efficiency.

The left drawing shows water entering a typical automotive engine cylinder during the intake stroke.
From the literatures, authors found that the effect of geometry has a negligible effect on the airflow during the intake stroke and early part of the compression stroke.
To determine the total air charge pumped into the cylinders, the simulation integrates the mass flow rate from the intake manifold and samples it at the end of each intake stroke event.
First, oxygen is combustible therefore, the more oxygen you put into the cylinders on the intake stroke, the better the gasoline will burn and the greater the power stroke will be.
The intake valve can be opened briefly during the exhaust stroke, the exhaust valve can be opened slightly during the Intake stroke, or exhaust can be recycled by simply postponing the exhaust valve closing.
Unfortunately, though this lengthens the power stroke relative to the effective intake stroke and extracts more energy from the fuel, it also lessens the amount of torque the engine produces (129 lb-ft @ 4,500 rpm for the hybrid vs.
Researchers initiate the simulations at the beginning of the intake stroke.
