PETROL ENGINE MODEL FOR PORT TIMING DIAGRAM

Product Description

PETROL ENGINE MODEL FOR PORT TIMINGDIAGRAM

Demonstrationof valve and port timing in internal combustion engines, the apparatus shallconsist of one Spark Ignition (SI) engine model and one Compression Ignition(CI) engine model integrated into a combined demonstration unit. The systemshall feature a precision-engineered rotating disc mechanism, enabling accuratevisualization of the complete engine cycle. It shall provide clear indicationof inlet valve/port opening and closing, exhaust valve timing, ignition timingfor the petrol engine, and fuel injection timing for the diesel engine. A fixedpointer or indicator shall be provided for precise crank position trackingduring operation. The front side of the apparatus shall be fitted with atransparent acrylic/plexiglass cover to ensure safe operation while allowingunobstructed observation of the working mechanism. The rotating disc shallpermit smooth manual operation and shall also have provision for optionallow-speed geared motor drive. All discs and timing markings shall bemanufactured from corrosion-resistant materials with durable engraved orpermanently printed graduations. The complete unit shall be mounted on aheavy-duty powder-coated mild steel frame with a stable base support, making itsuitable for classroom demonstrations as well as laboratory practical trainingin engine timing and working principles.
