If gear A turns clockwise, what will happen to gear B directly connected to it?

Gear B will turn counterclockwise

Gear B will turn faster in the same direction

What happens to the speed of a larger gear when it drives a smaller gear?

The larger gear spins faster than the smaller gear

It reverses the direction of the next gear

It keeps the direction the same

It stops the next gear from moving

It only affects gears that are far away

What is the effect on a gear train if the input gear is smaller than the output gear?

Camshaft: A rotating shaft in an engine that controls the opening and closing of the intake and exhaust valves. Aftercooler (air to air): A device that cools the compressed air from a turbocharger using outside air. Glow Plugs: Heating elements used to aid in starting diesel engines in cold temperatures. Timing Cover: The cover that protects the timing gears and belt or chain in an engine. Exhaust Manifold: A component that collects exhaust gases from multiple cylinders and directs them to the exhaust pipe. Oil Suction Tube: A tube that draws oil from the oil pan to the oil pump. Air Compressor: A device that increases the pressure of air and is often used to power air brakes or pneumatic tools. Oil Cooler: A device that cools the engine oil, helping prevent it from overheating. Supercharger/Blower: A device that increases the pressure of the air-fuel mixture entering the engine to boost power. Piston Rings: Rings around the piston that seal the combustion chamber, control oil consumption, and conduct heat. Crankshaft: A shaft that converts the linear motion of the pistons into rotational motion to power the vehicle. Oil Pan: A reservoir at the bottom of the engine that collects and holds the engine oil. Connecting Rod: Connects the piston to the crankshaft, converting the piston's motion into rotational motion. Stroke: The distance the piston travels within the cylinder, from top dead center to bottom dead center. 2 Cycle: A type of engine that completes a power cycle in two strokes of the piston. Crankshaft Main Bearing: The bearing that supports the crankshaft in the engine block. Aftercooler (water/coolant): A device that cools the compressed air from a turbocharger using water or coolant. Water Pump: A pump that circulates coolant through the engine and radiator to prevent overheating. Oil Filter: A filter that removes contaminants from the engine oil. Vibration Dampener: A device attached to the crankshaft to reduce engine vibrations. Piston Wrist Pin: The pin that connects the piston to the connecting rod. Valve Cover: The cover that protects the engine's valves and camshaft. Cylinder Block: The main structure of an engine that houses the cylinders and other components. ECM/ECU: Electronic Control Module or Electronic Control Unit, which controls various engine functions. Cylinder Head: The top part of the cylinder that contains the combustion chamber, valves, and spark plugs. Oil Pump: A pump that circulates oil through the engine to lubricate moving parts. Cylinder Liner: A sleeve inside the cylinder that protects it from wear and corrosion. TDC (Top Dead Center): The highest position the piston reaches in its stroke. Bore: The diameter of a cylinder in an engine. Flywheel: A heavy wheel that stores rotational energy to smooth out engine operation. Crankshaft Rod Bearing: The bearing that connects the crankshaft to the connecting rod. Push Tube / Push Rod: Rods that transmit motion from the camshaft to the valves. Piston: A cylindrical component that moves up and down within the cylinder to create power. Flywheel Housing: The casing that surrounds and supports the flywheel. Valve Lifter or Cam Follower: A component that follows the camshaft lobes to open and close the valves. Turbo: A device that increases the engine’s power by forcing more air into the combustion chamber. Intake & Exhaust Valves: Valves that control the intake of air and the exhaust of gases in the engine. Intake Manifold: A manifold that distributes the air-fuel mixture or air to the cylinders. Rocker Arm: A lever that transfers camshaft motion to the valves. Wastegate: A valve that controls the exhaust gases flowing to the turbocharger, preventing excessive boost pressure. Fuel Injector: A device that sprays fuel into the combustion chamber. Fuel Pump: A pump that moves fuel from the fuel tank to the engine. BDC (Bottom Dead Center): The lowest position the piston reaches in its stroke. 4 Cycle: A type of engine that completes a power cycle in four strokes (intake, compression, power, exhaust). Articulated Piston: A piston with two pieces (crown and skirt) joined by a pivot, allowing some flexibility in movement.
