**3.2 Diesel engine**

The Diesel engine used for this study is an air cooled, 4-cycles, single cylinder and 8 horse power Robin Engine. The Diesel engine is compact, lightweight and designed for generators, air compressor, water pumps, pressure washer and light construction machines (see Figure 6). The engine has a fuel tank of a capacity of approximately 14.5 liters (3.83 gallons), and a maximum horsepower rating of 8 HP at 3600 rotation per minute. The piston displacement is 348 cubic centimeters. The bore and stroke are respectively 82 and 78 mm. The engine combustion system has a direct injection. The engine dimensions are 435x370x478 mm and the engine weight is 46 Kg. A fuel flow meter is connected to the engine (see Figure 7) to record in real time the fuel consumption during engine testing.
