Abstract

a presente invenção se refere a um método para interromper um motor de combustão interna (101), sendo que o dito motor de combustão interna (101) tem pelo menos uma câmara de combustão (209) e um eixo de manivela (112) que é disposto para ser propelido pela dita pelo menos uma câmara de combustão (209), em que a admissão de gás para a dita pelo menos uma câmara de combustão (209) é controlada por pelo menos uma válvula de admissão (211), e em que a evacuação da dita pelo menos uma câmara de combustão (209) é controlada por pelo menos uma válvula de escape (213). o método inclui, quando o dito motor de combustão interna (101) deve ser interrompido: - desligar a injeção de combustível, - com a injeção de combustível desligada, controlar uma válvula de admissão (211) e/ou uma válvula de escape (213) da dita pelo menos uma câmara de combustão (209) de modo que, após a compressão na dita pelo menos uma câmara de combustão (209), a pressão na dita câmara de combustão (209) seja reduzida para reduzir uma potência propulsora de eixo de manivela (112) causada pela expansão de gás posterior à dita compressão.The present invention relates to a method for stopping an internal combustion engine (101), said internal combustion engine (101) having at least one combustion chamber (209) and a crankshaft (112) which is arranged to be propelled by said at least one combustion chamber (209), wherein the gas inlet to said at least one combustion chamber (209) is controlled by at least one inlet valve (211), and wherein The evacuation of said at least one combustion chamber (209) is controlled by at least one exhaust valve (213). The method includes, when said internal combustion engine (101) must be stopped: - Turn off the fuel injection, - With the fuel injection off, control an inlet valve (211) and / or an exhaust valve (213 ) of said at least one combustion chamber (209) such that, after compression in said at least one combustion chamber (209), the pressure in said combustion chamber (209) is reduced to reduce an axle thrusting power. crank (112) caused by expansion of gas after said compression.
