oil pan click to hear

Container closing the bottom of the engine block; it is the reservoir for the oil that lubricates the engine’s moving parts.

air conditioner compressor click to hear

Component of the air-conditioning system circulating coolant, which cools the air in the passenger compartment when it is hot outside.

flywheel click to hear

Disk connected to the crankshaft, which uses the kinetic energy produced at combustion to regulate the crankshaft rotation during the rest of the cycle.

exhaust manifold click to hear

Set of pipes at the exit of the cylinders, capturing the combustion gases to conduct them to the exhaust pipe.

spark plug cable click to hear

Electric wire carrying the high-voltage current from the distributor to the spark plugs, which produce sparks igniting the explosion.

cylinder head cover click to hear

Part of the engine covering the cylinder heads, where the fuel is burned.

vacuum diaphragm click to hear

Device connected to the distributor cap specifying the precise moment ignition must be produced relative to the engine’s rotation speed.

distributor cap click to hear

Unit supplying the electric current necessary for producing sparks that ignite the fuel in the engine.

oil drain plug click to hear

Plug closing the hole at the bottom of the oil pan through which used oil is evacuated.

fan belt click to hear

Rubberized bands mounted on a pulley and linked to the engine, driving the fan and the alternator.

pulley click to hear

Part attached to a shaft, whose rotational movement it transmits by means of a belt.

cooling fan click to hear

Mechanism with blades blowing air across the radiator in order to cool the liquid it contains.

alternator click to hear

Current generator driven by the engine, which recharges the battery to supply the electric system.

spark plug click to hear

Electric device whose two electrodes produce the spark necessary to ignite the air/fuel mixture in the cylinder.

rocker arm click to hear

Lever, activated by the camshaft, that drives the inlet and exhaust valves to open them.

piston click to hear

Metal moving part in the cylinder and attached to the connecting rod; it compresses the air/fuel mixture, then receives the thrust from the burned gases.

engine block click to hear

Main engine casing, which encloses the cylinders.

exhaust valve click to hear

Part that opens to allow the burned gases to escape.

oil pan gasket click to hear

Packing providing the seal between the oil pan and the engine block.

crankshaft click to hear

Shaft consisting of a series of cranks, which convert the alternate rectilinear motion of the piston/connecting-rod assembly into a continuous circular motion.

connecting rod click to hear

Articulated shank powered by the gas explosion; it transmits the thrust from the piston to the crankshaft.

piston skirt click to hear

Side surface of a piston guiding it along the inside of the cylinder.

piston ring click to hear

Circular ring mounted on the piston providing a seal between it and the cylinder.

combustion chamber click to hear

Part of the cylinder in which the pressurized air/fuel mixture is ignited and burned.

inlet valve click to hear

Part that opens to let the air/fuel mixture into the cylinder.

camshaft click to hear

Axle driven by a belt, a chain or gears connected to the crankshaft, controlling the opening and closing of the valves.

timing belt click to hear

Strap connecting the crankshaft to the camshaft.

valve spring click to hear

Spring that brings the valve back into the closed position.

intake manifold click to hear

Passages through which the air/fuel mixture enters the cylinder.

fuel injector click to hear

Device pulverizing the fuel in the combustion chamber.
