Spherical motorcycle engine combustion chamber

Abstract

The invention discloses a combustor of ellipsoidal motorcycle engine, which is constituted by the space between the cylinder cover and the piston. There are intake and outtake channels set at two ends of cylinder cover. The intake channel is high-level tangent air channel and the outtake channel is screw curved air channel. The top face of piston is cone-like convex face. On the cone-like convex face two concave surfaces are set, which are intersected with the cone-like convex face. The space formed by the first concave surface is the collision prevention pit of intake door and the space formed by the second concave surface is the collision prevention pit of outtake door. The space with petal-shape at the side face is formed by the bottom of cylinder cover, spherical concave pit and ellipsoidal pit, which are communicated from the top to the bottom. The space with petal-shape at the side face of cylinder cover is corresponding to the cone-like convex face at the top of piston. After the piston is assembled with the cylinder cover, the ellipsoidal combustor with petal-shape squish flow face is formed by the cone-like convex face on the piston and the space at the side face of cylinder cover. The combustor can strengthen the air flow disturbance of mixed air very well. It can improve burning and decrease HC discharge.

Description

technical field [0001] The invention relates to an engine combustion chamber, in particular to a motorcycle engine combustion chamber. Background technique [0002] The combustion chamber of the engine is a key part of the engine. Ordinary pistons are generally flat-topped, and the combustion chamber formed between it and the cylinder head is usually a relatively regular space similar to the shape of a bell. This kind of piston and cylinder head combustion chambers are generally more It is a spherical combustion chamber on the cylinder head. Its shape is simple, and it is not easy to make the piston fit well with the wall of the cylinder head to form a turbulent flow that is conducive to better combustion of the mixture. How to make the engine combustion chamber well strengthen the spark plug? The airflow disturbance of the mixed gas accelerates the flame propagation, improves the combustion, and reduces the emission, which has become a key technical problem in the current r...

Problems solved by technology

[0003] In order to solve the technical problem that the piston and the cylinder head combustion chamber in the combustion chamber of the motorcycle engine in the prior art are not easy to cooperate well to form a turbulent flow motion that is beneficial to the better combustion of the mixed gas, an ellipsoidal motorcycle is provided. Car engine combustion chamber, the elliptical combustion chamber can well strengthen the gas flow disturbance of the mixture near the spark plug, accelerate flame propagation, improve combustion, and reduce emissions
