AI Technical Summary
Existing diesel engine air intake systems for generator sets result in an increased overall height due to separate installation of pre-filters and air filters, leading to an inefficient and non-compact structure.
The air filter is installed on the side wall of the diesel engine flywheel housing through a connecting and transition bracket plate, connected via rubber elbow and straight pipe, reducing overall height and enhancing structural compactness.
The solution achieves a more compact generator set structure by integrating the air filter directly onto the engine, while also enabling early warnings through a sensor interface and preliminary filtration via swirl blades.
