Airbags deploy in a fraction of a second to provide a soft barrier between occupants and hard interior surfaces during a crash.The spark plug creates the spark that ignites the air-fuel mixture in the combustion chamber, starting the engine’s power cycle.The air filter traps dust, pollen, leaves, and other debris so only clean air reaches the engine for proper combustion.Brake pads press against the brake rotors (discs) when you step on the brake pedal, creating the friction that slows and stops the vehicle.Windshield wipers clear rain, snow, dirt, and other debris from the windshield so the driver can see the road clearly.The gearshift (or gear lever/stick) allows the driver of a manual-transmission vehicle to select different gears.The oil filter removes dirt, metal particles, and other contaminants from the engine oil so the oil can keep lubricating and protecting the engine.Pistons move up and down inside the cylinders. The force from combustion pushes them down, and that motion is converted into the rotation that ultimately turns the wheels.The radiator transfers heat from the engine coolant to the outside air, preventing the engine from overheating.The car battery supplies the high current needed by the starter motor and also powers electrical systems when the engine is off.Shock absorbers (and strut assemblies) dampen the up-and-down motion of the springs so the car doesn’t keep bouncing after hitting a bump.The muffler is part of the exhaust system. It uses chambers and baffles to quiet the loud pulses of exhaust gases leaving the engine.Tires provide the contact patch with the road for traction, braking, and handling, and they also absorb some road shock.The flywheel stores rotational energy from the engine’s power strokes and releases it during the non-power strokes, smoothing out engine operation and helping with gear shifts in manual transmissions.Fuel injectors spray a precise amount of fuel into the engine’s intake or combustion chamber at the right moment for efficient burning.The alternator converts mechanical energy from the engine into electrical energy to keep the battery charged and run lights, radio, and other accessories.The catalytic converter uses chemical catalysts to convert harmful exhaust gases (like carbon monoxide and nitrogen oxides) into less harmful substances.The starter motor is an electric motor that engages the flywheel or flexplate and spins the engine until it starts running on its own.The timing belt or chain links the crankshaft to the camshaft(s) so the valves operate in precise timing with the pistons.The crankshaft has offset journals connected to the pistons via connecting rods; as the pistons go up and down, the crankshaft spins.The camshaft has specially shaped lobes that push on the valve train components to open the valves at the right moments in the engine cycle.The steering wheel is connected (through the steering column and linkage or electric assist) to the front wheels so the driver can steer the vehicle.Headlights illuminate the road in front of the vehicle and also make the car more visible to other drivers.The exhaust system (pipes, muffler, catalytic converter, etc.) routes hot exhaust gases safely away from the engine and passengers.The transmission multiplies engine torque and provides different gear ratios so the car can accelerate, cruise efficiently, and reverse.The clutch allows the driver to temporarily disconnect engine power from the transmission so gears can be shifted smoothly.The brake rotor spins with the wheel. When the pads squeeze it, friction converts the car’s kinetic energy into heat and slows the vehicle.The fuel tank safely stores the vehicle’s supply of gasoline or diesel until it is pumped to the engine.The water pump is driven by the engine (usually via a belt) and keeps coolant flowing through the engine block, cylinder head, and radiator.The thermostat stays closed when the engine is cold so it warms up quickly, then opens to allow coolant to flow to the radiator once the engine reaches operating temperature.The serpentine belt snakes around several pulleys and transfers engine power to the various accessories that keep the car running and comfortable.This sensor tells the engine computer and the dashboard gauge how hot the coolant is so the system can adjust fuel mixture, fan operation, and warn the driver if needed.The oil pan forms the reservoir at the bottom of the engine where oil collects when the engine is not running and from which the oil pump draws oil.The hood is the hinged panel that covers the engine compartment and provides access for maintenance.Bumpers are designed to absorb low-speed impact energy and help protect more expensive body and mechanical components.The interior rearview mirror and exterior side mirrors give the driver essential visibility of traffic behind and beside the car.Seat belts keep occupants in their seats during hard braking or a crash, greatly reducing the risk of serious injury.The dipstick is a marked metal rod that is pulled out of the engine so you can see how much oil is present and whether it needs to be topped up.Fuses are sacrificial devices that melt and open the circuit if an overload or short occurs, protecting wiring and components from damage.The grille lets cooling air flow to the radiator while also contributing to the vehicle’s appearance and protecting the radiator from larger debris.You scored 0 out of 40You scored 1 out of 40You scored 2 out of 40You scored 3 out of 40You scored 4 out of 40You scored 5 out of 40You scored 6 out of 40You scored 7 out of 40You scored 8 out of 40You scored 9 out of 40You scored 10 out of 40You scored 11 out of 40You scored 12 out of 40You scored 13 out of 40You scored 14 out of 40You scored 15 out of 40You scored 16 out of 40You scored 17 out of 40You scored 18 out of 40You scored 19 out of 40You scored 20 out of 40You scored 21 out of 40You scored 22 out of 40You scored 23 out of 40You scored 24 out of 40You scored 25 out of 40You scored 26 out of 40You scored 27 out of 40You scored 28 out of 40You scored 29 out of 40You scored 30 out of 40You scored 31 out of 40You scored 32 out of 40You scored 33 out of 40You scored 34 out of 40You scored 35 out of 40You scored 36 out of 40You scored 37 out of 40You scored 38 out of 40You scored 39 out of 40You scored 40 out of 40
