Overview

Engine performance is not a datasheet claim.

An engine's rated RPM, torque and power figures only mean something once they are measured under controlled, repeatable load. The Dynamometer Engine Test Rig exists to put an engine under exactly that load and capture the numbers that matter, on the bench, before the engine ever ships.

The Neometrix Dynamometer Engine Test Rig is built around an Eddy current dynamometer — an electromechanical energy conversion device that converts the mechanical energy delivered by the engine under test into electrical energy, using Faraday's Law of electromagnetic induction as its working principle. This lets the rig apply a smooth, controllable braking load across the full operating range of the engine.

The system tests engines across a range of RPM, torque in N·m, and power, with all parameters displayed on the control panel. An engine monitoring system with digital meters tracks oil pressure, lube oil temperature, water temperature and engine RPM in real time, while a computer-based data logger records engine control parameters and a printer generates a printout report of all engine parameters.

Torque, speed and power validated against a real, controllable load — not against a spreadsheet.

In parallel, the rig records supporting engine parameters — lube oil pressure, engine temperature and water temperature — giving test engineers a complete picture of engine health alongside the primary performance figures.

System Architecture

Four subsystems, one test rig.

Load absorption, mounting structure, control and instrumentation, and data acquisition each do one job well — integrated into a single engine dynamometer test rig, run from one control panel.
