Our 4WD and twin axle truck/bus dynamometers allow Cornell’s to thoroughly test every on-highway application from a small passenger car through to a Heavy Duty truck. Combined with our full range of diagnostic scan tools, this allows us to monitor exactly what your engine is doing and isolate the problem.

Regular maintenance of your Diesel engine and integrated sub-systems (such as the fuel injection system) will ensure optimum performance is maintained. As the Diesel engine uses compression ignition, a simple compression test can be conducted to determine the integrity of the engine as an initial step, prior to making any other repairs or adjustments. The dyno test becomes another method of determining engine health and identifying underlying issues that may be present.

Most vehicle owners overlook the importance of a dyno test and think that a test will only provide you with more power and torque. A comprehensive dyno test will allow a technician to adjust your vehicle settings in a controlled environment where they will ensure your vehicle is running as optimally as possible. This may include adjusting air/fuel ratio (AFR) to gain the optimum fuel economy.

Whether your vehicle is suspected of running too rich or too lean, a technician can first identify the problem and then work out an effective resolution.

Cornell’s have installed two Dynolog Dynamometers from Mainline. This includes an All-Wheel Drive Chassis Dynamometer and a Heavy Vehicle (Bogie Drive) Chassis Dynamometer.

The AWD chassis dynamometer is a heavier duty version of the popular AWD1200 premium model, with larger than standard rollers, and upgraded roller shafts to handle higher vehicle weights. The unit can be used for RWD, FWD, AWD & 4WD light vehicle applications and medium trucks and buses.

The Heavy Vehicle Chassis Dynamometer is for testing single or twin axle (bogie drive) trucks and buses, with axle weights up to 20 tonnes. The bogie drive wheel base distance is motorised and automatically adjusted via the dynamometer control software system. This unit incorporates large twin eddy retarders on each axle (Quad Retarders) providing a massive torque capacity of 15200Nm, and a power absorption rating of over 4000kW (5360Hp).

Both units feature a multitude of data acquisition inputs, including the very latest “Emission Testing Technology” from Mainline DynoLog Dynamometers, including operator prompted drive cycle simulations for various emission standards for detailed exhaust analysis and fault finding.

The Heavy Vehicle Dynamometer also has the ability to interface directly to the vehicles on board diagnostic system and communicate via an SAE J1939 protocol, which is commonly used by many diesel engine manufacturers.
