Working Model Of Valve Timing Torquemaster-22 is a multicylinder engine valve timing cutaway model demonstrating the precise opening and closing of poppet valves controlled by the overhead camshaft. This Working Model Of Valve Timing shows a 4 stroke, 4 in-line cylinder engine with indirect injection, turbo supercharger, and toothed belt distribution. It enables measurement and diagramming of valve timing sequences and demonstrates variable valve timing concepts. Mounted on a sturdy powder coated metal stand, it is built for classroom demonstration.

Construction and Design
The Working Model Of Valve Timing Torquemaster-22 is built as a fully functional cut section system installed in a mobile solid frame. The engine is a 4 stroke unit with 4 in-line cylinders, featuring indirect injection fed by a turbo supercharger and a VE Bosch type rotary injection pump. An overhead camshaft driven through a toothed belt controls the valve timing. The mechanism is manually operated to demonstrate the precise timing of opening and closing of poppet valves. Parts are professionally painted in different colours to differentiate components, cross-sections, lubricating circuits, fuel system, and cooling system, with several parts chromium plated and galvanized for durability. The unit is mounted on a sturdy powder coated metal stand.
