Detección de alteración de motores ubicados en motocicletas

Abstract

The alteration of motorbike engines can be defined as the change of the original engine in order to achieve an improvement in the performance of the motorcycle. These changes can occur due to engine failure and the need for a replacement, which is initially legal, or a change to a higher engine which would give the motorbike more power, but also greater instability as the other components are not prepared for the increased power. Inadequate brakes may mean that the rider unwittingly puts his own safety and that of other road users at risk by using the altered engine. There is a criminal aspect to engine swapping. The origin of the engine may not be lawful and, although the driver of the vehicle is not directly responsible for a theft offence as he did not directly involve in the theft of the vehicle, he may be responsible for receiving it if he does not have the documentation justifying that he is a legitimate purchaser. Such documentation would shift the responsibility for the offence to the seller. The determination of criminal liability is secondary when the main difficulty is to know whether or not the installed engines belong to that motorbike. To this end, a study has been carried out to approximate, using mathematical methods that determine the degree of ownership, whether the engine fitted to a motorbike is the one that was originally installed in the motorcycle or whether it comes from another motorbike
