Title (EN) CONVERSION OF A 4-STROKE INTERNAL-COMBUSTION ENGINE TO A 2-STROKE INTERNAL-COMBUSTION ENGINE
(FR) TRANSFORMATION D'UN MOTEUR À COMBUSTION INTERNE À 4 TEMPS EN UN MOTEUR À COMBUSTION INTERNE À 2 TEMPS
(PT) TRANSFORMAÇÃO DE UM MCI DE 4 PARA 2 TEMPOS
Abstract: front page image
(EN)The present application for a patent of invention (PI) can be summarized in terms of the inventive step (IS) of converting a 4-stroke internal-combustion engine to a 2-stroke internal-combustion engine, as explained in the description, by adapting the valve control camshaft thereof to have identical projections on the two sides of the camshaft (5-Figure 2), and also by sealing the inlet of direct atmospheric air via the intake (6-Figure 1), said air then coming from the reservoir (7) for compressed air conveyed to the heat exchanger (6), said energizing operations being utilized to boost the energy supplied by fuel combustion in the cylinder (3-Figure 1).
(FR)En résumé, le présent brevet d'invention (BI) consiste, en termes d'activité inventive (AI), à transformer un moteur à combustion interne à 4 temps en un moteur à combustion interne à 2 temps, comme expliqué dans la description, par adaptation de l'arbre de commande de soupapes avec des saillies égales sur les deux côtés de l'arbre (5, fig. 2), et par fermeture hermétique de l'entrée d'air atmosphérique direct par l'admission (6, fig. 1), l'air venant alors du réservoir d'air comprimé (7) et étant acheminé vers l'échangeur de chaleur (8), d'où la mise à profit des alimentations en énergie pour renforcer celle produite par la combustion dans le cylindre (3, fig. 1).
(PT)Resume-se este Pedido de Patente de Invenção (PI) na Atividade Inventiva (AI) de se transformar um MCI de 4 para 2 tempos como explicado no Relatório Descritivo, adaptando-se o seu EVC com ressaltos iguais nos dois lados do eixo (5-fig.2). E também estancando-se a entrada do ar atmosférico direto pela admissão (6-fig.1) passando o mesmo a vir do reservatório de ar-comprimido (7), encaminhado ao trocador de calor (8) aproveitando-se essas energizações para somar à da combustão no cilindro (3-fig 1).
