The capacitor stores air compressed by the turbocharger during the
exhaust stroke, then uses the pressure in the vessel to force air into the cylinder during the intake stroke.
The power stroke occurs 0-180 degrees CA followed by the
exhaust stroke (180-360 degrees CA), intake stroke (360-540 degrees CA), and compression stroke (540-720 degrees CA).
During the four-stroke cycle, you might find that the
exhaust stroke is not fully successful some of the exhaust gases remain within the cylinder, which might mix with the incoming intake charge.
meaning that the mag doesn't fire into the
exhaust stroke, but it does fire into a fuel/air charge that's already well into combustion.
Thus during the
exhaust stroke there is a chance for the exhaust gases to escape from the combustion chamber which increases the volumetric efficiency of the engine.
The membrane, which is constructed from corrosion-resistant spring material, is larger than the piston and is fixed in such a way that it can be bumped by the piston at the extreme of the
exhaust stroke and flexed open while producing little or no noise and incurring no mechanical damage.
The
exhaust stroke occurs when the leading decreasing chamber volume (as the chamber moves uphill) forces the exhaust out, starting the cycle anew.
Figure 28, Figure 29 and Figure 30 demonstrate the oil film thickness on the liner after the first ring, the second ring, and the OCR respectively during the
exhaust stroke. In the expansion stroke, the ring pack had good conformability to the liner due to an increase of surrounding pressure.
The fail-safe cam profile is achieved by the brake gas recirculation event during the positive power
exhaust stroke being higher lift than the valve lash in the exhaust valvetrain (so higher lift than the other 3 brake cam events) when the actuator piston is retracted.
The
exhaust stroke cam profile has changed for required position of the follower under acceleration and retardation motion.
They operate on the same 4-stroke principle as your car engine or other 4-cycle engines, that is, intake, compression, power and
exhaust strokes, The Gade difference is that it does not have a traditional
exhaust stroke where, after traveling to bottom dead center on the power stroke, the piston pushes the hot burned gases up out of the top of the cylinder on the
exhaust stroke.
The inlet valve opens 4.5deg before TDC during
exhaust stroke
