What is ALPHABOX?

ALPHABOX is JAQUET’s predictive diagnostic system for combustion engines and only requires the input signal from a crankshaft speed sensor to analyze torsional vibrations as an early indication of mechanical failure in your engine.

No more unexpected breakdowns

Transport and logistic companies using diesel engine fleets are highly dependent on reliable and on timely delivery of the goods. Breakdowns of trains, vessels or trucks can lead to significant economic losses. JAQUET can help fleet owners to prevent such economic losses during its operation, by monitoring the engine with an ALPHABOX diagnostic system. The system is able to detect engine problems well in advance and gives you time to plan a maintenance cycle to prevent mechanical breakdowns.

Extended engine lifetime and quick return on your investment

ALPHABOX is a cost-effective engine diagnostic system with powerful functionality. It is easy to retrofit to combustion engines, providing a complete picture of the engine health including the effects of the whole power train. The ALPHABOX is based on analysis of the torsional vibration of the crankshaft. The system helps fleet owners to optimize maintenance cycles, extend engine life, avoid expensive breakdowns and reduce operational and maintenance costs.

Life cycle of a diesel engine

Easy to install and put into operation

Only a single speed sensor is necessary to obtain the general engine health status. For a detailed cylinder-specific health analysis, two speed sensors are required, one on the crankshaft and one on the camshaft. The built in webserver allows easy configuration by a standard web browser (no software installation on your PC or other devices required).

Clear diagnostic reports

Major engine and power train parameters (combustion, compression, injection, bearings, …) are indicated in green/yellow/red colors for clear interpretation. Green means “all ok”, yellow highlights a condition that might need a follow-up in the next maintenance cycle and red indicates a severe problem which requires immediate intervention.

A modular concept

The ALPHABOX can be configured with various hardware modules (GSM and GPS, memory extension, I/O modules, bus connections etc.) to make it easy to integrate the diagnostic unit in an existing environment.
