This video looks to answer many questions surrounding internal combustion engines and how they operate different with various air fuel ratios, ranging from lean to rich. A lean mixture means the engine does not have enough fuel to burn all of the air. A rich mixture means there is more fuel than needed in the combustion chamber, and not enough air to burn all of it. An ideal air fuel mixture is such that all the air and fuel is burned completely, with nothing left over. For a gasoline engine, this ratio is about 14.7:1. This video will answer the following questions: 1) At what air fuel ratio do engines burn the hottest? 2) Why do engines burn colder when rich? 3) Why do lean burning engines run colder? 4) Why do people believe that an engine running lean will actually burn hotter and cause problems?
