Title: Combustion engines' crosswords

Q: Name of the third stroke in a four-stroke engine.
A: POWER
Q: Place where a fossil fuel (such as coal) is burned. The heat produced is normally used to heat water.
A: FURNACE
Q: Machinery in a vehicle that turns engine power into movement forwards and backwards.
A: GEAR
Q: This device allows driving at night.
A: HEADLIGHT
Q: This mechanism is a system of gears that transmits an engine's power to the wheels.
A: TRANSMISSION
Q: The length of the piston movement inside the cylinder.
A: STROKE
Q: The place, in a steam engine, where the water is heated to be transformed into steam.
A: BOILER
Q: This case contains the lubrification oil; it is located under the block engine.
A: CRANKCASE
Q: Name of the fourth stroke in a four-stroke engine.
A: EXHAUST
Q: This mechanism allows the car to run on the roads without lot of movements. The external part is called a tyre and usually is made of plastic (rubber) with air inside.
A: WHEEL
Q: Piece inside a cylinder that has an up-and-down motion.
A: PISTON
Q: This engine is composed of blades, and steam or the gas makes turning its blades to achieve rotation movement.
A: TURBINE
Q: Solid fossil fuel.
A: COAL
Q: Compression-ignition engine that doesn’t need spark plug to initiate the combustion reaction.
A: DIESEL
Q: This engine uses a rotary design to convert pressure into a rotating movement following the thermodynamic Otto cycle.
A: WANKEL
Q: Machine that converts the energy stored in fuel into movement. (Useful work).
A: ENGINE
Q: This mechanism powers the electrical system.
A: BATTERY
Q: This mechanism allows to connect and to disconnect, voluntarily or automatically, a conductor shaft with a conduit shaft. This mechanism is used to change gears (to change the speed).
A: CLUTCH
Q: Gas obtained when the water is heated at more than 100 ºC.
A: STEAM
Q: Fuel used by yhe diesel cars.
A: GASOIL
Q: This car component allows the driver to look back.
A: MIRROR
Q: Component that produces the spark needed to start the combustion reaction in the petrol cars. (2 words)
A: SPARKPLUG
Q: Diameter of the circular chambers cut into the cylinder block.
A: BORE
Q: These mechanisms are an energy dissipater that allows reducing speed. (Plural)
A: BRAKES
Q: Engine used to transform steam into movement. (2 words)
A: STEAMENGINE
Q: Steam engine used to produce electricity. (2 words)
A: STEAMTURBINES
Q: Component of a car used to drive the car and decide the direction the car has to take. (2 words)
A: STEERING WHEEL
Q: Chemical reaction in which a fossil fuel is burned with oxygen to produce water (steam), carbon dioxide and energy (heat).
A: COMBUSTION
(4 letters). The word is the first word of the name of the component in a car used to change the velocity.
