Engine Types & Mechanisms

What is the function of a Piston in a reciprocating engine?

• Moves inside the cylinder to transfer energy.

• Controls the fuel intake in the engine.

• Regulates the engine temperature.

• Generates electrical power for the vehicle.

What are Hydrocarbons?

• Organic compounds consisting of carbon and hydrogen found in fuels like gasoline and diesel.

• Inorganic compounds that contain only carbon and oxygen, used in construction.

• Natural minerals that are used as catalysts in chemical reactions.

• Synthetic materials created from plastics and polymers.

What is an Internal Combustion Engine (ICE)?

• A type of engine that operates on electric power.

• A heat engine where fuel combustion occurs inside the engine, producing expanding gases that do mechanical work.

• An engine that uses solar energy to generate power.

• A type of engine that relies solely on external combustion.

What is Biodiesel?

• A type of fossil fuel derived from crude oil.

• A renewable fuel from vegetable oils or animal fats.

• A synthetic fuel made from coal and natural gas.

• A fuel that increases emissions and harms the environment.

What is the Brayton Cycle?

• A thermodynamic cycle used in gas turbines involving continuous intake, compression, combustion, and expansion.

• A refrigeration cycle that uses a compressor and evaporator to cool a space.

• A cycle used in steam engines that involves heating water to create steam.

• A process for converting solar energy into electrical energy.

What is a Rotary Engine?

• A type of engine that uses a triangular rotor spinning in an oval housing to perform intake, compression, combustion, and exhaust.

• An engine that operates on a linear piston mechanism for better efficiency.

• A traditional engine that relies on a circular crankshaft for power generation.

• An engine that uses a series of gears to convert rotational motion into linear motion.

What is a Heat Engine?

• A device that converts electrical energy into thermal energy.

• A machine that converts heat energy into mechanical work, operating on a cycle.

• A system that generates electricity from solar energy.

• A type of engine that runs solely on gasoline.

What is a Connecting Rod?

• Links piston to crankshaft.

• Connects the engine to the transmission.

• Supports the engine block.

• Regulates fuel flow to the engine.

What is Diesel fuel?

• A type of fuel that is denser than gasoline and used in compression-ignition engines.

• A fuel that is lighter than gasoline and used in spark-ignition engines.

• A renewable fuel made from vegetable oils and animal fats.

• A type of fuel that is primarily used in jet engines.

What did Rudolf Diesel invent?

• The steam engine in the 1800s.

• The internal combustion engine in the 1900s.

• The compression-ignition diesel engine in the 1890s.

• The electric engine in the 1900s.
