Diploma thesis on "Analysis of output parameters spark ignition engine operated on ethanol and gasoline", focuses on the issue of the operate of motor vehicles on the fuel mix of ethanol and gasoline. The theoretical part describes the use of biofuels as a fuel for internal combustion engines in the automotive industry and simultaneously focuses on the use of bioethanol, applied as an alternative fuel for spark ignition engines. The practical part is focused on evaluating the resulting changes of output parameters of the spark ignition engine of a car operated on fuel specified by the manufacturer and fuel consisting of a mixture of ethanol and gasoline at a ratio of 1:1. Based on the results of practical measurement it has been found, that during combustion mixtures of ethanol and gasoline has decreased significantly the content of harmful emissions in the exhaust gases, but also to a decline in performance and torque of the engine in comparison with gasoline. Due to the different properties of ethanol and gasoline is required when combustion of ethanol resp. its mixture to secure greater quantity of fuel injected. The increase of injected fuel results in higher fuel consumption.
