• Enables a wide range of investigations into the characteristics of four-stroke, single-cylinder petrol
and diesel engines
• Four-stroke diesel and four-stroke petrol engines available separately
• Includes comprehensive instrumentation
• Optional ancillaries available to extend the range of study even further
• Test bed trolley mounted for mobility
• Quick, convenient and accurate engine mounting and changeover
• Robust, simple hydraulic dynamometer
• No need for large electrical supplies
• Instrumentation and test bed are separate to avoid vibration being transmitted to measuring devices
• Self-sealing couplings enable quick and efficient connection and disconnection of fuel lines with
minimum loss or spillage of fuel
• Works with TecQuipment’s Versatile Data Acquisition System (VDAS®
