In this project we deal with the implementation of an idea related to a four-stroke engine with a centrally positioned ring-shaped valve. Such a design uses one annular valve for both intake and exhaust and achieves substantially increased flow parameters….
A two-stroke engine has many advantages and a number of manufacturers are developing a two-stroke engine currently. The main advantage is higher specific power output, smaller dimensions and weight, higher mechanical efficiency etc. The main problem of a two-stroke engine…
