Four Stroke

Two types of Strokes are (HOTS)

• Heat stroke, paralysis

• Ischemic stroke, Hemorrhagic stroke

• FAST, SLOW

• Hemiplegia, paraplegia

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

A petrol engine, during intake stroke draws

• petrol only

• a mixture of petrol and air

• air only

• none of the mentioned

What position are the valves in during the intake stroke

• Intake Closed, Exhaust Closed

• Intake Open, Exhaust Closed

• Intake Open, Exhaust Open

• I have no idea

What direction is the piston traveling during the Power-Stroke?

• Up

• Left

• Down

• Right
