Abstract

UN MOTOR DE CUATRO TIEMPOS QUE COMPRENDE UNA ESTRUCTURA DE MOTOR INCLUYENDO UN BLOQUE (111) Y UNA CABEZA (113), EL BLOQUE FORMANDO AL MENOS UN CILINDRO (114) Y UN CARTER (112). ES MONTADO UN PISTON (116) PARA RECIPROCIDAD EN EL CILINDRO (114), Y UN CIGUEÑAL (117) Y LA BARRA DE CONEXION (118) SON MONTADAS EN EL CARTER (112) Y CONECTADOS AL PISTON (116). EL CARTER (112) INCLUYE UNA PUERTA DE ENTRADA DE COMBUSTIBLE (128) Y UNA PUERTA DE SALIDA, Y UN CONDUCTO CONECTA LA PUERTA DE SALIDA (131) A UN PASO DE ADMISION (132) EN LA CABEZA. LA PUERTA DE ENTRADA (128) ESTA CONECTADA A UN SUMINISTRO DE UNA MEZCLA DE COMBUSTIBLE QUE COMPRENDE COMBUSTIBLE, ACEITE LUBRICANTE Y AIRE. DURANTE LA OPERACION DEL MOTOR, LA MEZCLA FLUYE A TRAVES DEL CARTER (112), EL CONDUCTO (132), Y EL PASO DE ADMISION DE AIRE (128) AL CILINDRO (114). LAS VALVULAS (119,120) Y LOS MECANISMOS DE ACTIVACION DE LAS VALVULAS CONTROLAN EL FLUJO DE LA MEZCLA AL CILINDRO (114) Y EL FLUJO DE SALIDA DEL CILINDRO. EL ACEITE EN LA MEZCLA LUBRICA LAS PARTES DEL MOTOR EN EL CARTER (112), LAS VALVULAS (119,120) Y LOS MECANISMOS DE ACTIVACION DE LAS VALVULAS. EL CONDUCTO (132) PREFERIBLEMENTE FORMA UN TANQUE PLENO O DE ARRANQUE QUE CONTIENE LA MEZCLA BAJO PRESION. EL MOTOR DEBE INCLUIR MAS QUE UN CILINDRO Y EL PISTON, TAL COMO UN MOTOR DE DOS CILINDROS QUE TIENE PISTONES QUE SE MUEVEN EN SINCRONISMO PARA PRODUCIR LA COMPRESION DEL CARTER.
