Four-stroke internal combustion engine e.g. thermal pneumatic hybrid engine, operating process for motor vehicle, involves injecting additional air quantity during compression phase to obtain desired engine torque instantaneously

摘要

The process involves injecting, during the operation of a four-stroke internal combustion engine at low torque, an additional quantity of air in a combustion chamber (3) during compression phase of the normal cycle of the engine from an air-brake reservoir (4). The reservoir is connected to the chamber using a charge valve (13). The air is injected to obtain the desired engine torque instantaneously.
