MD-ASM-150-AWD (4×4) Overview

The MD-ASM-150-AWD (4×4) tests both axles of the test vehicle under the same imposed load; while at the same time providing for front-to-rear axle speed synchronization. Front-to-back roller speed synchronization protects AWD center diﬀerentials, provides for a means to safely test 2WD vehicles with traction control, and allows for testing to be performed under real-world load conditions. The MD-ASM-150-AWD (4×4) accommodates wheelbases from 86 to 128 inches (218 – 325 cm) without moving parts.

High throughput demands of Centralized Emission Inspection require the use of rugged and durable emission inspection equipment. Designed from inception to withstand punishing use and misuse, Mustang Dynamometer has set the performance standards of equipment manufactured and used worldwide for centralized emissions testing. Our pioneering experience has led us to be the world leader in the design and manufacturing of rugged inspection and maintenance hardware and software for the I/M industry. We have centralized testing lanes installed all over the world in climates from cold to hot and from wet to dry. By the end of 2016 we estimate that our equipment has tested nearly 850 million vehicles. Continuous improvement leads us to innovative solutions based on our knowledge of design, service, maintenance, ergonomics and overall functional capabilities. Mustang I/M Centralized Emission Inspection equipment is designed for our customer’s demands. Compliant with EPA, BAR, and CENAM ASM speciﬁcations.
