Posted December 31, 2013. The expansion chamber is a bandaid to cover up one of the primary disadvantages of a symetrically timed 2-stroke engine... During the compression stroke, the exhaust ports remain open long after the intake ports have closed so much of the intake charge (power) is lost through the exhaust port.C m = 0.166 x L x N. Where: C m is mean piston speed, in feet per minute. L is stroke, in inches. N is crankshaft speed, in revolutions per minute. Thus, using again the Kawasaki F-5 engine as an example, with L being 2.68-inches and N given as 9000, we find that. Cm = 0.166 x 2.68 x 9000. Cm = 4000 ft/min.Everything with a two stroke is a compromise. While flattening out the pipe doesn't change the power much, the flatter you go the more likely it will have a negative affect. For a 500cc engine I probably wouldn't go thinner than say 2.5". The expansion chamber doesn't need to be straight.visit my new website for automotive contents https://autonews9.com/

A 2-stroke engine is a type of reciprocating engine that uses only two strokes of the piston to complete a power cycle.

When talking about a 2-stroke power band, these dirt bikes have maximum power in the upper-mid range towards their topmost end. …Power bands in a 2-stroke dirt bike and a 4-stroke dirt bike are different. All engines have power bands but not perceivable in the same way; the optimal range varies for each bike. A 4-stroke power band is gradually distributed through the whole RPM range and picks power in a constant mode.A 2-stroke power valve is nothing more than a piece of metal slid into the engine’s exhaust port. Its primary function is to regulate the size of the exhaust port, thus enabling the engine to deliver controlled power throughout the rev range. Back in the day, two-stroke engines had very limited power bands. For example, a 2-stroke utility ATV ...Although both 2-stroke and 4-stroke motors undergo all four phases of combustion to complete each full power cycle, the 2-stroke engine only needs two strokes and of course the 4-stroke needs four.

1) Get going in a particular gear (say, 3rd) and let the engine idle down while still underway. 2) Quickly give it 1/8 full throttle and hold it there throughout the rev range, then slow it back down to idle. 3) Note any stumble or bog from the engine. 4) Repeat steps 1-3 at 1/4 throttle, 1/2 throttle, 3/4 throttle, and full throttle. The exhaust pipe of a two-stroke engine attempts to harness the energy of the pressure waves from combustion. The diameter and length of the five main sections of a pipe, are critical to producing the desired power band. The five sections of the pipe are the head pipe, diffuser cone, dwell, baffle cone, and the stinger. engine components to create the perfect power band. TWO-STROKE PRINCIPLES Although a two-stroke engine has less moving parts than a four-stroke engine, a two-stroke is a complex engine because it relies on gas dynamics.
