The Anatomy of the Two-Stroke Engine: Part Five

Now that you’re well acquainted with the two-stroke cycle and its advantages, it’s time to look at the downside—because let’s be honest, there’s always a downside.  Here are a few reasons we don’t see the two-stroke engine used in automobiles and for other large-scale applications:

~Longevity: the fact that you have to mix the Evinrude XD 100 oil with the gasoline means that there isn’t a direct means of lubrication to the system, which leads to expedited wear and tear.

~Efficiency: two-stroke oil can be expensive, and the engine guzzles it up. As an example, you would use about one gallon of oil every 1,000 if there were a two-stroke engine in your car. You’d also notice a decrease in your gas mileage.

~Pollution: as stated above, two-stroke engines burn a lot of oil, equating to a lot of pollution.
