Engine Endurance and Durability Testing

Engine endurance and durability testing, for engine manufacturers and their suppliers.

Intertek is an industry leader in engine durability and endurance testing.  Programs primarily include performance and validation testing on engines and engine components. Customers include all of the automotive and heavy duty engine manufacturers, and their suppliers.

Intertek engine test stand configurations meet diverse testing requirements and needs. Precision data acquisition and control systems provide flexible and repeatable engine control. Data acquisition rates vary depending on customer requirements, with typical rates at once/minute and once/stage.  Intertek uses “flight recorder” data acquisition, gathering data at a high rate (such as 100 Hz) to help determine root-cause due to engine or engine component failure. Some test stands are also equipped with emission measurement equipment.  Humidity and temperature intake air control is available, as well as precise control of various other temperatures and pressures such as engine oil and coolant using PID loop control. 

Intertek tests a variety of engine configurations,  including single cylinder, multi-cylinder, research, prototype, and production engines. A variety of fuels are used, including gasoline/gasoline blends, diesel, alternative fuels and natural gas (including CNG). 

Engine and engine components are constantly evolving, becoming more sophisticated, and are being developed at a more rapid pace and at less cost than ever before. Intertek's facilities allow our customers to meet these new challenges.
