    In the present experimental work the Otto cycle performance of a 1600 cubic centimeter internal combustion engine (MECH) of a private vehicle was evaluated by distributing surface temperatures using thermography. The data was used using technological equipment: thermal camera, thermocouple, digital thermometer, anemometer and absolute pressure meter. In addition, the thermograms were obtained to temperatures, velocity, pressure of exhaust gases. The theoretical performance analysis was performed using an indirect method generating a 65 percent. Due to,there were leaks caused by heat transfer (convection in the engine block and oil pan) and heat leaks in exhaust gases (11.72kilowatt) and the cooling system (8,037 kilowatt). Thus, It was determined a performance of 33.15percent. Meanwhile, exergetic analysis the perfomance was 43.25 percent. Consequently, the evaluation of pollutant production shows that it is in the values of carbon monoxide (CO) and hydrocarbons (HC) do not exceed the limits of the NTE INEN 2204: 2017 standard, which details the maximum limits allowed according to the year of the vehicle.
