Dynas3 LI (Low Inertia)

Overview

DYNAS3 is specially designed to satisfy today’s and future testing demands formulated by the automotive and supplier industry. The power ranges represent the torque characteristics of advanced gasoline and Diesel engines for passenger cars and commercial vehicles. Using a torque measuring flange and top mounted independent blower keeps the dynamometer compact and saves space. The DYNAS3 LI is part of the DYNAS3 series and were developed for testing small in-line up to high-output engines.

 

Features

DYNAS3 LI is a range of absorbing and motoring machines for all test applications in the field of spark ignition and compression ignition engines. Low moments of inertia and high overload capacity together with speed gradients above 12.000 rpm/s guarantee a highly dynamic response.

The DYNAS3 LI is part of the DYNAS3 Series and were developed for testing a wide range of modern engines. Air cooling by blowers simplifies dynamometer installation and does not require tapping into other cooling systems inside the test cell. The state-of-the-art and future-oriented technology of the DYNAS3 Series guarantees a long-term dynamometer solution at a low-cost investment.
