Detailed Description

The present invention will be described in detail with reference to fig. 1 to 4, and the technical solutions in the embodiments of the present invention will be clearly and completely described, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the present invention provides an engine, including an engine assembly and engine accessories, an air nozzle 1.1, a fuel nozzle 1.2 and a spark plug 1.3 are respectively installed on a cylinder head 1.12 of the engine assembly, an exhaust passage 1.11 is opened in a combustion chamber in the cylinder head 1.12, an exhaust valve 1.5 is installed at an exhaust port of the exhaust passage 1.11, and the exhaust valve 1.5 is connected below an exhaust camshaft 1.4 arranged on the cylinder head 1.12;

below the combustion chamber 1.6 in said cylinder 1.7 is a piston 1.8, which piston 1.8 is connected to a crankshaft 1.10 by means of a connecting rod 1.9.

In the present embodiment, as shown in fig. 2, the engine assembly is externally connected with an air compression pump 2.4, and the air compression pump 2.4 is connected with the crankshaft through an engine accessory belt; the air compressor pump 2.4 compresses air and then feeds the compressed air into an intercooler 2.2 of the engine, a part of the cooled air is directly fed into the air nozzle through a pipeline, and redundant cooling air enters a storage tank 2.3 which is connected with the air nozzle 2.1 through a pipeline.

The air compression pump is connected with an engine crankshaft through an engine accessory belt, when the engine works, the air compression pump also works, the air compression pump pressurizes air and then inputs the air into the intercooler through a pipeline, a part of the cooled compressed air enters the air storage tank to be stored and used when the ignition is performed next time, and the other part of the compressed air goes to the air nozzle through the pipeline and is used for air inlet of the engine.

As shown in fig. 3, the air nozzle 3.1, the fuel nozzle 3.2 and the spark plug 3.3, at the upper end of the cylinder, represent the time nodes of their operation, which are close to the point where the piston reaches the top dead center, but not the top dead center.
