ICE Engine operation Flashcards
(26 cards)
What does ICE stand for in the context of engines?
Internal Combustion Engine
True or False: An internal combustion engine operates by burning fuel and air to create heat and pressure.
True
Fill in the blank: The four main strokes of a four-stroke engine are intake, ______, power, and exhaust.
compression
What is the purpose of the intake stroke in an internal combustion engine?
To draw in a mixture of air and fuel.
What happens during the compression stroke?
The air-fuel mixture is compressed, increasing its temperature and pressure.
Which stroke is responsible for the power output in a four-stroke engine?
Power stroke
What occurs during the exhaust stroke?
The burnt gases are expelled from the cylinder.
Multiple Choice: What type of fuel is commonly used in internal combustion engines? A) Diesel B) Electricity C) Hydrogen D) All of the above
A) Diesel
Define ‘spark ignition’ in relation to internal combustion engines.
A method where a spark plug ignites the air-fuel mixture.
True or False: Diesel engines use compression ignition.
True
What is the role of the crankshaft in an internal combustion engine?
To convert linear motion of the pistons into rotational motion.
Fill in the blank: The ______ system provides the air-fuel mixture to the engine.
fuel injection
What is the function of the camshaft?
To operate the engine’s valves.
Multiple Choice: Which of the following components is NOT part of an internal combustion engine? A) Cylinder B) Alternator C) Piston D) Spark Plug
B) Alternator
What is the significance of the engine’s displacement?
It indicates the total volume of all the cylinders in the engine.
True or False: A turbocharger increases the engine’s efficiency by forcing more air into the combustion chamber.
True
What is the purpose of the cooling system in an internal combustion engine?
To maintain the engine at a safe operating temperature.
Fill in the blank: The ______ converts the energy from combustion into mechanical energy.
piston
What is a common method used to measure engine power?
Horsepower or torque measurement.
Multiple Choice: Which component controls the timing of the engine’s valves? A) Piston B) Camshaft C) Crankshaft D) Fuel Injector
B) Camshaft
What is the primary function of the exhaust system in an internal combustion engine?
To expel exhaust gases and reduce noise.
True or False: The air-fuel ratio is critical for optimal combustion in an internal combustion engine.
True
What does the term ‘octane rating’ refer to?
The measure of a fuel’s ability to resist knocking during combustion.
Fill in the blank: The ______ is a component that helps regulate the engine’s air intake.
throttle
