Four Cylinder Diesel Engine Dynamometer

 General Description

Simple to use and safe to operate, this lab trainer is extremely friendly.  Equipped with a variable load dynamometer and computer linked for accurate data capture and analysis, this unit will provide many hours of accurate, repeatable data that can be used in a variety of problem-solving activities. The engine can be operated remotely via a LAN Network with the remote control option.

Standard Equipment:

The base model Four Cylinder Dynamometer comes complete with the following:

Includes Dell Computer with 17” Flat Panel

Four Cylinder Diesel engine Test Stand with Yanmar 4TNV88-BDSA Engine

Reliable & Durable

The TNV engines now proudly take up the running as Yanmar’s premium small industrial diesel. They offer even more enhanced durability due to better block cooling, a stiffer crank and pistons, finer tolerance in the journal and more. CAE analysis has brought lower vibrations and higher strength to the mounting structure for even better reliability in heavy-duty jobs
