Embodiment Construction

[0014] Such as figure 1 and figure 2 As shown, a negative pressure engine is composed of body, cylinder 2, cylinder head 7, piston 3, combustion system, gas distribution mechanism and crankshaft connecting rod mechanism 1 and other components. The gas distribution mechanism is in the cylinder head 2 is equipped with an intake valve 5 and an exhaust valve 4; wherein, the gap between the piston 3 and the cylinder head 7 when the piston 3 is at the top dead center can ensure that the piston 3 cannot touch the cylinder head 7, generally not greater than 2mm, that is, only set Small free clearance, the contact sealing surface of the intake valve 5 and exhaust valve 4 and the cylinder head 7 is set on the top surface of the cylinder head 7, the entire cylinder space when the piston 3 is at the bottom dead center is used as the combustion chamber 8, and the injection of the combustion system The oil nozzle and the spark plug 6 are installed at the bottom dead center of the piston 3...

Abstract

The invention discloses a negative pressure engine and its working cycle process. It is composed of a body, a cylinder, a cylinder head, a piston, a combustion system, a gas distribution mechanism and a crankshaft connecting rod mechanism. There are intake valves and exhaust valves on the top; the gap between the piston and the cylinder head when it is at the top dead center is enough to ensure that the piston does not touch the cylinder head, and the contact sealing surface of the intake valve, exhaust valve and the cylinder head is set on the cylinder. The top surface of the cover, the entire cylinder space when the piston is at the bottom dead center is used as the combustion chamber, and the fuel injector and spark plug of the combustion system are installed at the bottom dead center of the piston on the cylinder wall. In the present invention, under the condition of the same fuel consumption, as long as the cylinder diameter is appropriately increased, the power generated is much larger, the noise is reduced, and the fuel is saved.

Description

technical field [0001] This invention relates to engines. Background technique [0002] The engine is the power source of the car, and the engine is also widely used in various aspects such as transportation machinery, agricultural machinery, construction machinery and generator sets. There are many types of engines, among which two-stroke and four-stroke engines are the most common, belonging to reciprocating piston internal combustion engines. The internal combustion engine converts the heat energy generated by fuel combustion into mechanical energy by means of the state change of the working fluid. According to the type of fuel used, it is divided into three categories: gasoline engine, diesel engine and gas fuel engine. They all rely on the high temperature and high pressure generated by fuel combustion to perform work. [0003] The main structure of the engine is composed of the body, cylinder, cylinder head, piston, combustion system, valve mechanism, crankshaft and...
