Dwell time is directly proportional, while the tool feed rate is inversely proportional to the amount of heat generated by the friction among the tool and magnesium alloy billet. The interaction effect is highly significant for the strength values of tubes produced with dwell time less than 30 s and tool feed rate higher than 25 mm/min.

A stock, 5 hp. Briggs & Stratton engine uses a 3.875" rod and has a 2.437" stroke which equals a 1.59 rod ratio.We know that by changing the rod to 4.475" and using the same stroke, the ratio increases to 1.863 and the engine produces more power and rpm. The most important thing that a longer rod does is increase the dwell time of the piston ...

There is an ideal rod length to stroke ratio. The 4 strokes commonly used today are so far away from that perfect ratio, I doubt that .020" is going to help any. People will tell you that it will help the dwell time at TDC. I have a spreadsheet that checks that dwell time.

Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2″ feed and making a product as fine as 35-48 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.

The rod-to-stroke ratio also impacts the dwell time of the piston at TDC, measured in crankshaft rotational degrees. With a longer dwell period, the piston will stay at TDC for more degrees of the crankshaft's rotation before moving down toward BDC. The benefits of a longer dwell at TDC are myriad.

I just hunted up a Stover K pic, and it looks like the valve open dwell time adjustment is made by adjusting push rod length back near the flywheel. Valve open dwell time should be about 220 degrees of flywheel rotation (35 degrees BBDC +180 degrees of exhaust stroke + 5 degrees ATDC). Last edited: Nov 3, 2021. A.
