Multi-cylinder internal combustion engine of fuel injection type |
摘要 |
An induction system for a multiple cylinder internal combustion engine embodying a simplified fuel injection arrangement that reduces the number of injection nozzles. The engine is provided with a relatively large cross sectional area main induction system and a relatively small cross sectional area auxiliary induction system. A valving arrangement is incorporated so that a major portion of the engine charge requirements are supplied to the chambers through auxiliary induction system at idle and low speed. As a result, turbulence in the combustion chamber at the time of ignition is increased to provide improved fuel economy and exhaust emission control. One fuel injection nozzle is positioned in an inlet passage of the auxiliary induction system which serves a plurality of chambers. In this way, one injection nozzle can serve multiple chambers without adversely affecting mixture distribution. In accordance with another embodiment of the invention, pairs of injection nozzles are provided in this common inlet which are fired alternately so that each nozzle serves separate cylinders.
