Abstract

The invention discloses a pre-combustion chamber, an engine and a vehicle. Waste gas in the pre-combustion chamber is stably and uniformly exhausted, the influence of residual waste gas on combustion stability is reduced, the combustion heat efficiency is improved, and emission is improved. The pre-combustion chamber comprises a cavity, a gear, a triangular rotor and an ignition device. The cavity is provided with a pre-combustion cavity, the gear is rotationally installed on the cavity wall of the cavity and located in the pre-combustion cavity, the triangular rotor is arranged in the pre-combustion cavity, the triangular rotor is provided with an inner gear ring and meshed with the gear through the inner gear ring, and the inner molded surface of the pre-combustion cavity is matched with the motion trail of the triangular rotor. A mounting hole communicating with the pre-combustion cavity is formed in the cavity wall of the cavity, and the ignition device is mounted in the mounting hole; and more than two spray holes penetrating through the cavity wall are formed in the cavity wall of the cavity, the pre-combustion cavity communicates with a combustion cavity of a main combustion chamber of the engine through the spray holes, waste gas in the pre-combustion chamber is scavenged through the triangular rotor, residual waste gas in the pre-combustion chamber is reduced, and combustion in the pre-combustion chamber is more stable.

Description

Technical field [0001] ENGINE TECHNICAL FIELD The present invention relates in particular to a precombustion chamber, the engine and vehicle. Background technique [0002] Precombustor is a small internal combustion gasoline engine combustion chamber, a precombustion chamber may be connected through orifice penetrating the main combustion chamber, the combustible mixture into the precombustion chamber in the intake stroke, the ignition by the electrode. After the formation of the flame front igniting air-fuel mixture from the pre-chamber orifices outflow surface, and igniting the combustible mixture in the main combustion chamber. A plurality of ignition sites within the combustion chamber can be sufficiently air-fuel mixture burned faster and more. [0003] The exhaust gas after the combustible mixture combustion in the precombustion chamber will affect the stability of combustion, thereby affecting the thermal efficiency and emissions. However, the prior art combustion exhaust ...
