Catan models all use four-stroke engines while much of the competition is using two-stroke, why?
A. There is a huge difference in four-stroke (also known as four cycle) and two-stroke (also known as two cycle) engines in the way they operate, perform, last, and many other ways. All cars on the road today use four-stroke engines while two-stroke engines are used in chain saws, some lawn mowers, some outboard boat engines, and some off-road dirt bikes. To keep this basic, a two-stroke engine mixes or injects two-stoke oil in with the gas and this gas/oil mixture is used to lubricate the engine and ultimately used in the combustion. Due to the lack of proper valves and that the gas oil mixture can leak out the exhaust this system is very polluting, the lack of a proper lubrication system means a shorter engine life, the oils are expensive, and from efficiencies the fuel economy of a two-stroke engine is not as good as from a four-stroke engine. Two-stoke engines are good for having a low lb/hp ratio and for short bursts of performance as well they are less expensive to manufacture. F
