Trucaje de la culata del motor G10 del vehículo SUZUKI FORSA I y validación en un dinamómetro de rodillos para verificar el cambio de las curvas paramétricas de torque y potencia

Abstract

This technical project aimed to repower the engine of a Suzuki Forsa I with a trick in the cylinder head through the oversizing of the intake ducts and the manufacture of a header for a fast gas outlet without turbulence. Regarding the engine G10 an investigation was made of issues related to the vehicle's tampering, a torque-power test to determine the initial operating parameters, then disassembled the electrical and mechanical components to be able to remove the header. After this, a sizing was carried out. A study of fluids was carried out in the same to determine the volumes, flows, and speeds to be obtained; continuing with the trickling process and following the set dimension parameters. With the rigged head, he settled into the engine and placed their new electrical and mechanical components, as well as a header that replaced the exhaust manifold. A torque-power test was developed with the butt plug, employing a graphical and statistical analysis with the data to compare the before and after values, highlighting considerably an increase in torque and power values. And the stability of these values as the engine operating regimes increase is observed a 153% increase in these values. It was concluded that the gender differences considerable torque and power; in addition to considering that the test engine is in optimal conditions. It is recommended to carry out bibliographic reviews on the effects of cylinder head oversizing that may affect engine power and torque.
