Here; loading of the engine was done by a water brake, the brake moment was determined electronically, the fuel consumption was measured by mass. In the experimental setup; ambient air, lubrication oil, fuel, exhaust temperatures and inlet and outlet temperatures of cooling water, exhaust gases and cooling water in and out to exhaust calorimeter temperatures were measured by using of type K thermocouples. Also, an exhaust calorimeter produced by Cussons
was mounted onto the test system.
