Description

Technical Field

[0001] The invention belongs to the technical field of engine intake mechanisms, and in particular relates to an intake mechanism for a motorcycle engine. Background Art

[0002] A motorcycle engine air intake device realizes air replenishment to the engine combustion chamber by combining an air filter, an intake manifold, and an intake valve mechanism, thereby improving the engine's air intake efficiency and performance. The device comprises an air filter intake pipe connected to the air filter inlet, and the air filter outlet is connected to the carburetor intake port through the air filter outlet pipe. The carburetor outlet is connected to the engine combustion chamber through the engine intake pipe. In particular, a sealed air supply tank is fixed on the air filter outlet pipe, and its inner cavity is connected to the inner cavity of the air filter outlet pipe through the air inlet and the air outlet. The air inlet of the air supply tank is equipped with an air intake valve that enables gas to flow from the air filter outlet pipe to the air supply tank in one direction, and the air outlet is equipped with an air outlet valve that enables gas to flow from the air supply tank to the air filter outlet pipe in one direction. This design can replenish air to the engine's combustion chamber through the air supply tank to improve the engine's intake efficiency and ensure that the oil-gas mixture ratio in the engine's combustion chamber always meets the requirements so that the mixture can be fully burned, thereby increasing the engine's power and torque and ensuring the engine's performance.

[0003] The prior art provides an intake mechanism for a motorcycle engine (Announcement No.: CN220869545U), which includes an intake passage having a first branch of the air passage and a second branch of the air passage, a first valve cooperating with the first branch of the air passage, a second valve cooperating with the second branch of the air passage, and a first camshaft for driving the first valve and a second camshaft for driving the second valve; the cross section of the first branch of the air passage is larger than the cross section of the second branch of the air passage, and the first camshaft and the second camshaft are engaged and disengaged.

The rotating rod drives the filter plate to rotate, and the impurities on the surface of the filter plate are thrown out by rotation to avoid clogging of the filter plate. When the filter plate rotates, the sealing frame seals the connection between the filter plate and the mounting block, which can avoid the problem that the air filter needs to be removed for cleaning after the air intake shell has been used for a period of time.
