What do you need to know about crankshaft position?
Make certain that the Battery is in a fully charged condition. You’ll need to test for spark at all cylinders to be certain that there’s no Spark present at all. If Spark is present, the Crankshaft Position is working properly. Test for Fuel Injector Pulse, although depending on the fuel system design this is not always possible.
What do you call a rod exiting through a crankcase?
Whether its a rod exiting through the side of a crankcase, valves imprinting into the piston, or any other major catastrophe, these events illicit fear, confusion, and gratitude among engine owners.
What should the voltage be when cranking the engine?
Finally the rule of thumb, if you’re using Volts DC mode; is that this Signal should output the amount of Voltage that comes into the Sensor on the Power Circuit. So, when you crank the engine, you should see anywhere between 9 to 12 Volts. If the (CKP) or (CMP) Sensor is BAD, you’ll get no reading.
Where is the piston located on a 4 stroke engine?
Pressurized air is administered via the spark plug hole and two pressure gauges are used to make the comparison. The piston is positioned at top dead center on the power stroke. Air exiting the combustion chamber can then be traced back to the valves, head gasket, or piston rings.
Why does a stroker crank need a shorter piston?
The specialized stroker crank has dramatically increased the amount of stroke you can add to your stock bottom end. Stroker cranks require a shorter piston to keep the factory sized piston from extending beyond the deck surface, it is also shortened to accommodate a longer rod.
How do you increase stroke on a stock crank?
One of the methods used to increase stroke with a stock crank, is called offset grinding. By offset grinding the rod journal you move the centerline of the rod journal away from or toward the centerline of the main journal. This will result in increased or decreased stroke.
How does a stroker motor affect the displacement of the engine?
Though a bit exaggerated for effect, the stroked cross section in Figure 2 incorporates: Keep in mind that rod length does not affect the displacement of the engine, it is common to have a stroker motor that uses an increased crank throw, decreased piston compression height, and stock rod length to achieve additional stroke.
What does Def mean on a stroker motor?
Stroker Motor (def.) A motor that has greater than stock displacement due to an increase in the factory crank throw. An increase in crank throw increases stroke (the difference between the piston’s top dead center and bottom dead center position).
