emissions

Category: Jet Ski

The 2 stroke engine has always had a problem with hydrocarbon (unburnt gas) emissions. The amount of overlap, the time when the intake and exhaust are both open, can not be controlled as well as a 4 stroke can with it’s valves. This is the same problem that has plagued the rotary engine until recently, when a new port configuration was used on them. Unfortunately another problem with two strokes is that most people want to build them up and make more horsepower. Normally a tuned exhaust is one of the first modifications done, due to a large increase in power for a reasonable amount of money. The purpose of an expansion chamber is to reflect a pressure wave back to the cylinder. If timed correctly in a certain rpm range, this strong pulse will be reflected away from the cylinder which creates a vacuum at the cylinder. The overlap period takes atvantage of this situation as the fresh intake air rushes into the cylinder. As the air fuel mixture fills the cylinder it does a great job of increasing the volume which translates to power.
