Abstract: The experimental investigation of Diesel engine 6135ZCa equiped with pressure exchanger are presented. In comparison to engine 6135Ca which is unsupercharged, the power of 6135ca with pressure exchanger is raised and the fuel consumption is decreased. Its performance is better than the engine 6135ZCa equiped with Turbo-supercharger 10ZJs-2 in the lower engine speed conditions.

Key words: combined cyclogram, constraint metamorphic mechanisms, equivalent resistance, forms of metamorphic joint, task-motion mapping
