Sentences with phrase «hydraulic tappets»
Hydraulic tappets are tiny components in an engine that help ensure smooth and efficient operation by controlling the opening and closing of valves. They use fluid pressure to maintain the correct clearance between the tappet and the valve, allowing the engine to run smoothly and quietly. Full definition
