CUBIC CAPACITY.
The size of an engine is usually ex- I pressed in terms of its cubic capacity, J measured in cubic centimetres. The capacity of a single cylinder is the, volume swept out by the piston in moving from the top to the bottom of its stroke. Being the volue of a cylinder, it is found by squaring the bore, multiplying the result by the stroke, multiplying again by 3 l-7th and, finally, dividing by four. In the caso of a multi-cylinder engine the total capacity will equal the capacity of one cylinder multiplied by tho number of cylinders. It is important to notice that if the bore and stroke in millimetres are used for finding the capacity bv the above rule, the result must be divided by 1000 to convert it from cubic millimetres to cubic centimetres. Note, also, that one litre is equal to 1000 c.c.
