SOCA-CABRERA, José Ramón; CHAVARRIA-IRIGOYEN, Salvador  and  MARTINEZ-ROCHA, Marcos. Speed and Load Characteristic Curves of the Volkswagen 1.9 SDi Engine. Rev Cie Téc Agr [online]. 2019, vol.28, n.2 ISSN 2071-0054.

The diesel engine tests are standardized and are governed by standards that allow determining the main parameters of the engine's operation. This paper shows the results of the tests carried out on the Volkswagen 1.9 SDI engine with the Armfield CM12 test bench, carried out in the Diesel engine laboratory of the Department of Agricultural Mechanical Engineering (DIMA) of the Autonomous University of Chapingo (AUCh). The SAE J1995 methodology was used to adjust the characteristic curves of torque and gross power, as well as the hourly and specific fuel consumption using the methods of scanner and balance. In addition, the lambda λ index variation was obtained. It was obtained that the maximum power regime varies by 4.1% and the maximum power by 16.7%, in relation to the nominal; the average minimum specific consumption is 179.5 g / kWh.

Keywords : engine; testing; effective parameters.
