automobile systems: main parts
A vehicle is composed of basic mechanical parts and devices making up its systems; each of them fulfills a specific function.
Rubberized bands mounted on a pulley and linked to the engine, driving the fan and the alternator.
Mechanism with blades blowing air across the radiator in order to cool the liquid it contains.
Vessel in which the coolant, which circulates around the engine, is cooled by means of flowing air.
spark plug cable
Electric wire carrying the high-voltage current from the distributor to the spark plugs, which produce sparks igniting the explosion.
Current generator driven by the engine, which recharges the battery to supply the electric system.
Unit storing the electricity produced by the alternator and releasing it to supply the vehicle’s electric system.
Unit supplying the electric current necessary for producing sparks that ignite the fuel in the engine.
Control for the gearbox that is manually activated by the driver to govern the actions of the gearbox.
Unit changing the ratio between the rotation speed of the engine and that of the wheels in the forward gears, or reversing the rotation in the reverse gear.
Mechanism disengaging and reengaging the engine and the gearbox in order to change gears.
Lever that the operator presses with the foot to activate the brake system.
Mechanism amplifying the force exerted by the driver on the brake pedal.
Lever in the passenger compartment that is connected to the rear wheels; the driver manually activates it to stop the vehicle or in case of emergency.
System of tubes containing a fluid that activates the brakes when they come under pressure from the pedal.
Braking mechanism comprising a disc attached to the wheel, whose rotation is slowed down when the brake pads exert friction on it.
Mechanism transmitting the steering wheel’s rotational motion to the steering gearbox.
Circular instrument used by the operator for steering the guide wheels.
Device removing dust from the air entering the engine.
cylinder head cover
Part of the engine covering the cylinder heads, where the fuel is burned.
Tubular conduit conducting the combustion gases from the exhaust manifold to the catalytic converter.
Set of pipes at the exit of the cylinders, capturing the combustion gases to conduct them to the exhaust pipe.
Conduit connected to the tank for filling it.
Reservoir containing the fuel that makes the vehicle self-sufficient.
Tubes connecting the tank with the engine and supplying it with fuel by means of a pump.
Transversal axle transmitting the rotation from a differential to a wheel.
Gear system located between the two wheels, allowing them to rotate at different speeds and compensating for the difference in distance that they travel when the car turns.
Axle transmitting the rotation of the transmission to the differential.
Unit joining the suspension components to the vehicle’s body.
Telescopic cylinder, pneumatic or hydraulic, reducing the spring’s oscillations.
Elastic metal shank wound up in a spiral, supporting the weight of the vehicle and absorbing the shocks caused by any unevenness in the road.
Conduit expelling the combustion gases from the muffler to the ambient air.
Tubular conduit carrying the combustion gases from the catalytic converter to the muffler.
Compartmentalized chamber in which the escaping gases expand, thus reducing the noise from the engine.
Chamber in which toxic substances contained in the escaping gases are broken down to make them less toxic.
gas supply system
Set of components supplying the fuel to the engine.
Set of components transmitting the motion produced by the motor to the wheels.
Set of components that joins the wheels to the vehicle’s body while reducing shocks caused by the road’s unevenness and improving the hold on the road.
Set of components that reduce the vehicle’s speed, eventually to a halt, and keep it in place while parked.
Set of components that direct the front wheels to guide the vehicle as it moves.
Engine in which a mixture of air and gasoline is compressed and ignited to produce an explosion whose energy is converted into mechanical energy.
Set of components that prevents the temperature of the engine from rising excessively.
Set of components supplying the necessary current for starting the vehicle and operating its electric accessories.
Set of components designed to expel the engine’s burned gases into the ambient air.
