intake stroke

intake stroke

[′in‚tāk ‚strōk]
(mechanical engineering)
The fluid admission phase or travel of a reciprocating piston and cylinder mechanism as, for example, in an engine, pump, or compressor.

Also, temperature swing TBCs enable lower insulation temperature during intake stroke which would prevent heating intake air.
Through the intake stroke and early part of the compression stroke, the particle temperatures drop, consistent with the heat transfer to the much cooler fuel-air mixture for an intake air temperature of 20[degrees]C.
At that point, a bigger lobe on the crankshaft engages the rockers, increasing the duration and exposure of the intake stroke, effectively increasing horsepower.
found that a small injection of fuel during the NVO interval and a second injection during the intake stroke result in internal fuel reformation, which improves the ignitability of the cylinder mixture [103].
The unit underwent a full model change in 2011 as MCHP1.0K2, featuring Honda's EXlink (Extended Expansion Linkage Engine)(2), 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. Water, unlike the fuel/air mixture, is incompressible and, during the compression stroke, locks the piston in place as shown in the drawing at the right of Figure 1.
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.
