The bore is reduced while the stroke is not lengthened to maintain the required displacement. [Solution] If we consider a square combustion chamber with a displacement of approximately 500cc, a bore and stroke of 54mm x 54mm x 4 pistons results in a very small bore and stroke of 494.6cc, compared to a normal single-piston engine with a bore and stroke of 85.72mm x 85.72mm and a displacement of 494.6cc. With an area ratio of 2.52 to 1 compared to a normal single-piston engine, the 4 pistons will experience more than 2.5 times the combustion pressure if the compression ratio is the same. If a normal single-piston 3-cylinder 1484cc engine produces 100 horsepower, then a 4-piston engine would theoretically produce 250 horsepower. And all this with the fuel efficiency of a naturally aspirated 1.5L engine. Although there are considerable mechanical losses due to the movement of four pistons and two crankshafts, the resulting increase in power more than compensates for these losses.
