Expo interview: Nituj Bhatnagar

Nituj Bhatnagar, affiliate business manager, AVL List GmbH, explains some of the challenges involved with fuel consumption measurement


Tell me about your presentation at Automotive Testing Expo India 2014, and why it's important for the industry.
Rising fuel prices, strict legal limits for CO2 reduction, increasingly complex engines and growing cost pressure means that measuring fuel consumption efficiently and precisely is becoming more and more important. In addition, fuel consumption is a key factor in the vehicle choice that consumers make. This means fuel consumption measurement is an important area in engine development.

What are some of the challenges faced in optimizing fuel consumption?
Development engineers are under a great pressure to find an ingenious balance between fuel economy, performance, emissions and cost. On the one hand, minimum fuel consumption of the engines must be covered, and on the other hand, even with the lowest fuel flow rates, an exact and reproducible determination of the fuel consumption must be ensured with only one measurement system.

What are the key ways to achieve fuel consumption optimization?
For efficient development of combustion engines, it requires a repeatability of +/-1g/kWh in specific fuel consumption at engine part load (low rpm, low torque). For this it’s necessary to consider the overall measurement chain including engine torque and speed measurement, fuel measuring device, fuel conditioning unit, installation and application.

How can your tools help vehicle developers achieve this?
AVL devices are built to ensure the requisite repeatability and accuracy for every application in the engine as well as for the vehicle. This allows development engineers to shorten the time it takes to achieve development objectives with high levels of availability of the engine testbed and reducing the test effort: one example is the reduction of the measurement time during automatic engine calibration. With its state-of-the-art fuel calibration system AVL offers a measurement quality program to calibrate the overall fuel circuitry.

How can fuel consumption optimization continue to be improved?
Only by taking a holistic approach to the entire system (measuring device, test bed setup, engine, application) efficient fuel consumption measurements can be further impoved.
