AVL FUEL SYSTEM COMPACT™ (CHINA)

The AVL FUEL SYSTEM COMPACT™ is designed to meet the demands of basic R&D, endurance, quality and end-of-line applications. 


AVL Approach

Fuel efficiency and CO2 reduction are key topics in the automobile world. To ensure minimum fuel consumption, engines are validated on testbeds.

The AVL FUEL SYSTEM COMPACT™ is designed to meet the demands of steady state testing in development, endurance, performance and end-of-line applications. With a measuring range from 0 to 125 kg/h and a conditioning unit with integrated heating, it covers applications from small engines up to heavy-duty diesel truck engines with 600 kW. The AVL FUEL SYSTEM COMPACT™ can be used with a range of fuel injection systems.

Its compact design ensures easy installation on a wall or optionally on a trolley. It is easy to operate, either from its user-friendly control panel, or by means of a testbed automation system.

The fuel supply temperature conditions are easily adjustable and tightly controlled, while automatic bubble detection and forced venting guarantee reliable measuring results at any time.

More than 10,000 AVL fuel measurement devices in the field stand for proven technology. In a complex testing environment, AVL FUEL SYSTEM COMPACT™ provides a simple, precise, and robust solution to measure fuel consumption.

Measuring Principle

AVL Fuel Meter COMPACTTM Measurement Principle
The fuel passes through a U-shaped tube, which vibrates with its natural frequency. This frequency is proportional to the fuel density, which, in addition to the mass flow, is a separate measurement variable and thus allows the output of volumetric measurement values. The time lag of the vibration frequency C1 to C2 is proportional to the mass flow.
