            High-quality, cost-effective four-stroke, single-cylinder              Operating environment: 
            diesel engine for use with TecQuipment’s Small Engine Test             Well ventilated laboratory
            Set (TD200). Adapted specially for education to enable                 Storage temperature range: 
            effective laboratory testing and demonstrations, the 
            engine includes an exhaust thermocouple, a half-coupling               –25°C to +55°C (when packed for transport)
            to link to the test bed dynamometer and all essential hoses            Operating temperature range:
            and fittings. 
            In addition, each engine includes a colour-coded fuel                  +5°C to +40°C
            tank with self-sealing couplings. The couplings ensure                 Operating relative humidity range: 
            the engine can be connected and disconnected quickly                   80% at temperatures < 31°C decreasing linearly to 50% at 
            and efficiently with minimum loss or spillage of fuel. For             40°C
            convenience and safety, the fuel tank can be removed                   Noise levels:
