Product Description

CAMA (Luoyang) Electromechanic Co., Ltd (Original named Nanfeng), affiliated with China Airborne Missile Academy, is the biggest and leading dynamometer and power test bench manufacturer in China.
CAMA exclusively introduced eddy current dynamometer technology from Germany ZOLLNER GMBH in 1988. With military manufacturing history of fifty-year, advantage of quality control system in airborne enterprise, CAMA successfully sold about 6000 engine test benches to more than 800 customers all over the world.
Nowadays CAMA eddy current dynamometers hold over 85% market share in China, products are exported to America, Australia, Russia, Turkey, Malaysia, Singapore, Vietnam, Iran, Mongolia, Laos, etc. About 6,000 sets of CAMA eddy current dynos are running in CAMA's more than 800 customers' company.

Besides of various power test bench system, CAMA produce various measurement equipment for engine,  motor, gearbox, transmission test, including dynamometer, fuel mass flow meter, intake air flow meter, engine blow-by meter, engine coolant temperature conditioning device, engine fuel conditioning device, boost air system,  air conditioning system, chilling water system, etc.


The YLQ series blow-by meter is used for the continuous measurement and monitoring of the blow-by gas flow that escape via leaks from the pistons and piston rings ( also from the bearing and bearing gaskets of turbo-charged engines). Based on the differential pressure principle, the meter consists of flow sensor, differential pressure transmitter, and pressure steadying system, features high measurement accuracy and large test range, applying to different types of engines.

Application Areas:
  • Monitoring engine operation
           - condition of the pistons, piston rings and cylinder wall;
  • Engine endurance testing and running-in monitoring
           - manufacturing quality control; acceptance testing;
  • Engine development
           - piston adjustment, lubrication improvement;
  • Engine research
          - engine oil testing (piston temperature, oil deposits,etc).
