Abstract
The growing concern for the environment, as the sustainable use of non-renewable resources and the desire in reducing fuel consumption by consumers, comes against the constant increase of demand on emission standards and new creations programs. The Innovate-Auto, which has in its objectives, support the protection of the environment and promote energy efficiency through tax incentives to the automotive industry. Thus, it becomes essential to the need for the development of more efficient engines. Thus, some parameters to be observed during a calibration of an internal combustion engine are the temperature and humidity of the intake air. Since this temperature may influence during combustion, which can result in loss of power and /or increased fuel consumption. This study evaluates one of the influences of air admitted into an engine, which works on Otto cycle temperature. Thus, it was analysed the power of the engine through the test results through variation and control of air admitted to the same temperature. The tests were conducted using a small counter dynamometric based on the concept applied the Prony brake connected to an internal combustion engine with a cylinder, four-stroke Otto cycle running at maximum output of 5.5 hp, and a control device for temperature variation of air admitted.
