A stroke is the action of a piston travelling the full length of its cylinder.In a two-stroke engine, one of the two strokes combines primarily the intake stroke and the combustion stroke, while the other stroke primarily combines the compression stroke and the exhaust stroke, though technically since both ports are exposed during both the combustion and compression strokes, some reversion ...
When the transfer is complete, the piston is on the compression stroke but the exhaust port is still open, an unavoidable problem with the two stroke piston port design. To help prevent the piston pushing fresh mixture out the open exhaust port the strong acoustic wave (produced by the combustion) from the expansion chamber is timed to arrive ...
Commander Limited includes air ride suspension, an am/fm radio with four speakers, an iPod adapter, XT package and built-in touch screen GPS. All Can Am ATVs except the DS-70 and the DS-90 feature four-stroke Rotax engines. The maverick side by side was introduced to stand up to the Commander's rival the Polaris RZR XP 900.
Polaris then recalled the sleds and quickly developed a new prototype to avoid bankruptcy. [8] The new model, the 1965 Mustang, became a hit as a family snowmobile and boosted Polaris sales. Polaris continued to develop snowmobiles similar to this model throughout the 1960s-1970s, and went on to become one of the leaders in the snowmobile industry.

Cylinder and ports, viewed from above. Schnuerle porting [1] [2] is a system to improve efficiency of a valveless two-stroke engine by giving better scavenging.The intake and exhaust ports cut in the cylinder wall are shaped to give a more efficient transfer of intake and exhaust gases.
