【Abstract】 The exhaust pipe of 8 cylinder diesel engines with Mixpc turbo-charging system is separated according to its possible firing order, and some basic principles are presented for the optimization of structural parameters. Performance simulation is carried out with finite volume method whick numerical flux is calculated with total variation diminishing scheme, and based on this, structural design of MIXPC system is made for varies type of diesel engines. Some general rules are obtained for the design of MIXPC system and suggestion is given to its series production.更多还原
