Abstract
<B>"MOTOR DE COMBUSTãO INTERNA DO TIPO DOIS TEMPOS DE CáRTER LIMPANTE"<D>. A presente invenção trata de um motor de combustão interna do tipo dois tempos de cárter limpante, intencionado para uma ferramenta de trabalho, preferivelmente uma serra de corrente (moto-serra) ou um cortador (podador), e provido com um abafador (2) leve e compacto. O motor é arranjado com uma particularmente alta compressão do cárter nele criada em pelo menos um enchimento (3), (4), (5), (6) que é localizado dentro da área de compressão (7) sob o pistão do motor (8) na forma de um enchimento de balanço (3) e/ou um enchimento de pistão (4) e/ou um anel perfurado de pistão (5) e/ou um enchimento estacionário (6), ao mesmo tempo que o motor é provido com um estrangulamento especialmente forte criado na região de exaustão do motor, isto é, no seu orifício de exaustão (9) e/ou em um possível duto de exaustão (10) e/ou em um abafador (2).
