Embodiment Construction

[0011] figure 1 Shown: A free piston 4 with a hole is installed in the small cylinder combustion chamber 1 of the engine, so that the small cylinder combustion chamber 1 constitutes a front combustion chamber 7 and a rear combustion chamber 8, on the top of the small cylinder combustion chamber 1. There is a spark plug 2 for an ignition device, the free piston 4 has a suitable central small vent 5 and a punched combustion chamber 3, the vent 6 communicates with the engine block 10, and the engine piston 9 matches the engine block 10.

[0012] When the engine of the present invention is in compression and working state: the engine piston 9 moves upward, and the gas first pushes the free piston 4 to the top of the small cylinder combustion chamber 1, and then continues to compress the gas to the set compression ratio; when the engine crankshaft causes the engine piston 9 When the angle is set after running to the top dead center, the spark plug 2 ignites to ignite the gas in the fr...

Abstract

The invention provides a stamping detonation combustion engine with a free piston. The stamping detonation combustion engine is characterized in that the volumes of most combustors in a cylinder head of a gasoline engine are eliminated, the eliminated volumes are replaced with a small cylinder combustor, a spark plug is arranged at the top end of the small cylinder combustor, the small cylinder combustor is divided into a front combustor and a rear combustor by the free piston, the free piston is provided with a central small ventilation hole and a stamping combustor, and the lower part of the small cylinder combustor communicates with an engine cylinder. According to the arrangement, the combustor of the engine is incompletely divided into the front combustor and the rear combustor by the free piston; during the working stroke of the engine, the spark plug is ignited, a gas in the front combustor is ignited, and the free piston is pushed to perform stamping combustion; owing to quick and effective self-pressurized accelerated circulating combustion, the initial free diffusion combustion is quickly converted into detonation combustion, the combustion process is finished and the engine is acted; and the stamping detonation combustion engine realizes quick and safe detonation combustion and is an efficient and clean engine.

Description

Technical field [0001] The invention relates to an engine, in particular to a free piston ram-detonation combustion engine. Background technique [0002] The piston engines currently in use convert the internal energy of oil and gas into mechanical power through ignition or compression ignition. Although great progress has been made after many years of development, there are also disadvantages that are difficult to overcome, such as low combustion efficiency and large exhaust emissions. Realizing an engine with high efficiency, high torque, low fuel consumption and low emissions is a dream that people have been pursuing for many years. Summary of the invention [0003] The purpose of the present invention is to meet the current market’s urgent need for high-efficiency and low-polluting emission engines, and to provide a free piston ram-detonation combustion engine and its combustion technology, which have higher efficiency (detonation combustion) than existing gasoline engines. ...
