The internal combustion engine starting pressure reducing device comprises a mechanism for controlling opening and closing of an exhaust valve, and the mechanism for controlling opening and closing of the exhaust valve enables the exhaust valve of the internal combustion engine to be gradually transited from a pressure reducing opening state to a closing state in the starting stage. The hand-pulling starting success rate of the internal combustion engine, mainly a diesel engine, can be effectively increased, safety is improved, and accidents caused by reverse force are prevented. On the basis, the device also has other possible positive effects, such as improvement of the power section of an internal combustion engine, mainly a diesel engine, capable of being started by hand pulling. 本发明公开了一种内燃机启动减压装置，包括控制排气门启闭的机构，所述控制排气门启闭的机构是使内燃机排气门在启动阶段从减压打开状态逐渐过渡到关闭状态的机构。本发明可以有效提高内燃机、主要是柴油机的手拉启动成功率，提高安全性，防止反向力造成意外事故。在此基础上，此装置也可能产生的其他积极效果，比如提高能够手拉启动的内燃机、主要是柴油机功率段。
