Inputs

Use either a decimal point or comma where needed.

Model assumption

The model assumes a fixed mechanical coupling between the engine and the wheels and actual combustion. Clutch slip, torque-converter slip, tyre slip and fuel cut-off during overrun are not considered.

Results

Power strokes are treated as evenly spaced across all cylinders.

Power strokes per second
Power strokes per kilometre
Distance until the same cylinder's next power stroke
Time between consecutive power strokes

How it is calculated

Vehicle speed is converted to metres per second. A four-stroke engine produces z / 2 power strokes per crankshaft revolution; a two-stroke engine produces z.

f = (n / 60) × strokes per revolution
s = (v / 3.6) / f

Power strokes along the road

Power strokes along a scaled road Enter valid values to display the scaled road.

The actual cylinder sequence is engine-specific. Only the calculated recurrence of the same cylinder is highlighted.

Vehicle not to scale. Road and power strokes are.

Aerodynamics is not allowed to be involved.
