camshaft, camshafts
def. A shaft fitted with several cams, whose lobes push on valve lifters to convert rotary motion into linear motion. The opening and closing of the valves in all piston engines is regulated by one or more camshafts.

biela, F, bielas
|
connecting rod, connecting rods
def. The metal rod that connects a piston to a throw on a crankshaft.

cárter, M, cárters
|
crankcase, crankcases
def. In an internal combustion engine, is the housing for the crankshaft. The enclosure forms the largest cavity in the engine and is located below the cylinder block.
|
|
cilindrada, F, cilindradas
|
|
|
cilindro, M, cilindros
|
cylinder, cylinders
def. The round, straight-sided cavity in which the pistons move up and down. Typically made of cast iron and formed as a part of the block.

|
colector de admissão, M, colectores de admissão
|
intake manifold, intake manifold
def. The network of passages that direct air or air-fuel mixture from the throttle body to the intake ports in the cylinder head. The flow typically proceeds from the throttle body into a chamber called the plenum, which in turn feeds individual tubes, called runners, leading to each intake port. Engine breathing is enhanced if the intake manifold is configured to optimize the pressure pulses in the intake system.

compressor volumétrico, M, compressores volumétricos
|
supercharger, superchargers
def. An air compressor used to force more air into an engine than it can inhale on its own. The term is frequently applied only to mechanically driven compressors, but it actually encompasses all varieties of compressors—including turbochargers.

intercooler, M, intercoolers
|
intercooler, intercoolers
def. A heat exchanger that cools the air (or, in some installations, the intake charge) that has been heated by compression in any type of supercharger. It resembles a radiator; it houses large passages for the intake flow, and uses either outside air or water directed over it to lower the temperature of the intake flow inside.

pistão, M, pistões
|
piston, pistons
def. Is a component of reciprocating engines, pumps and gas compressors. It is located in a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, it also acts as a valve by covering and uncovering ports in the cylinder wall.
|
|
turbo, M, turbos
|
turbocharger, turbochargers
def. A supercharger powered by an exhaust-driven turbine. They always use centrifugal-flow compressors, which operate efficiently at the high rotational speeds produced by the exhaust turbine.
|
|
válvula, F, válvulas
|
|
|
vela, F, velas
|
spark plug, spark plug
def. Is an electrical device that fits into the cylinder head of some internal combustion engines and ignites compressed aerosol gasoline by means of an electric spark. They have an insulated center electrode which is connected by a heavily insulated wire to an ignition coil or magneto circuit on the outside, forming, with a grounded terminal on the base of the plug, a spark gap inside the cylinder.

|
volante do motor, M, volantes do motor
|
Flywheel, Flywheels
def. A heavy disc attached to an engine's crankshaft to increase its rotary inertia, thereby smoothing its power flow.
