Industrial Engine Specifications

This document provides specifications for a 4JB1 four cylinder, four cycle, water cooled diesel engine. It lists details like the bore and stroke, displacement, compression ratio, weight, dimensions, coolant and oil capacities, rotation direction, and standard features like the alternator, starter, and flywheel housing. It also provides the industrial power ratings of 70 intermittent and 61 continuous horsepower at 3000 RPM, as well as 132 lb-ft of maximum torque at 2000 RPM. A power curve graph shows the torque and horsepower curves for intermittent and continuous operation.
