Internal Combustion Engine

The main function of the engine _______ is to let air in and out of the cylinders.

• Camshaft

• Valves

• Rocker arm

• Connecting Rod

A four-stroke cycle engine is an internal combustion engine that utilizes four distinct piston strokes to complete one operating cycle. What are the 4 basic steps in the correct order?

• Intake, Power , Compression, Exhaust

• Compression, Power, Intake, Exhaust

• Intake, Exhaust, Compression, Power

• Intake, Compression, Power, Exhaust

A four - stroke engine generates power _____ time(s) during a complete cycle.

• 1

• 4

• 2

• 3

During the intake stroke, ________________________________.

• Spent gases are forced out of the combustion chamber from the piston's travel from BDC to TDC

• Fuel is supplied to the combustion chamber

• Air - fuel mixture is deposited into the combustion chamber

• The piston travels from BDC to TDC to compress the fuel charge prior to ignition

Ignition of the charge occurs in between the following two strokes: _________________ and _________________.

• Intake, Power,

• Compression, Power

• Power, Exhaust

• Intake, Compression

Compression is a key element of an internal combustion engine. Which engine component supplies the compression needed to power an engine?

• Crankshaft

• Ignition Armature

• Connecting Rod

• Piston

The piston travels from BDC to TDC with the exhaust open on which stroke?

• Exhaust

• Compression

• Intake

• Power

The CYLINDERS where the PISTONS are housed are in one line (1 Bank) and upright.

• Boxer

• Inline

• V-Engine

• Rotary Engine

During a power stroke the piston moves down with_____

• A Vaccum

• Valves Opened

• Great Force

• Large Spark

Which of the following is not an internal combustion engine

• 2-stroke petrol engine

• steam turbine

• 4-stroke petrol engine
