Intake system of an internal combustion engine |
摘要 |
An internal combustion engine comprising a carburetor having a throttle valve. A secondary throttle valve is arranged in the intake passage at a position located downstream of the throttle valve of the carburetor. When the engine is operating under a light load, the secondary throttle valve remains fully closed. When the engine is operating under a heavy load, the secondary throttle valve remains fully opened. The intake passage located upstream of the secondary throttle valve is interconnected with the intake passage located downstream of the secondary throttle valve via an auxiliary intake passage having a cross-sectional area which is extremely smaller than that of the intake passage.
