概要

• 論文の詳細を見る

• The present investigation evaluates the effect of the auxiliary fuel on the performances of a diesel engine by changing the shape of prechamber, and reveals the following points : (1) The maximum output of the engine with intake fuel addition rises almost to the same level independently of the prechamber types. (2) This increase of the output is caused by the improvement of overall thermal efficiency owing to rapid combustion in the main chamber, though the aspirated mixture gives no effect on the utilization of the oxygen contained in the cylinder. (3) The exhaust smoke is beneficially affected by the manifold introduction of auxiliary fuel. However, various unburned hydrocarbons can be detected in abundance.
