| Abstract: | In connection with the tube band type intercoolers widely adopted by vehicle diesels, the relation between engine running parameters and intercooler cooling efficiency and resistance coefficient is detected through simulating calculation and experimental test. An air to air intercooler model, which connects intercooler cooling efficiency and resistance coefficient with turbo charge pressure ratio, intake air mass flow, environment temperature and pressure, is presented. It has a good coincidence with the experimental result. And the simulating calculation results of turbocharge intercooling engine is also satisfied when it is used. |
