CARBON DEPOSIT SIMULATION BENCH AND METHODS THEREFOR

摘要

A carbon deposit simulation bench (10) for evaluating effects of an engine system liquid (70) on an engine surface (82,92) that experiences an engine pressure and an engine temperature includes a test chamber (12) having a high surface area test specimen (14) positioned therein. The carbon deposit simulation bench (10) also includes an air supply system (16) including an air supply conduit (18) fluidly connecting an air supply source (20) with the test chamber (12), and a liquid circulation loop (26) configured (to) circulate the engine system liquid (70) through the test chamber (12). A temperature control subsystem (42) simulates the engine temperature within the test chamber (12), and a pressure control subsystem (46) simulates the engine pressure within the test chamber (12).
