what is GAS 4 CYCLE?

Question

what is a 4 cycle gas engine, what type of gas does it us???

Answer 1

Are you talking about the Otto Cycle?
The standard 4 stroke cycle of most automotive gasoline engines.
1. Intake Stroke
2. Compression Stroke
3. Power Stroke
4. Exhaust stroke.

The type of gas it uses is the standard gasoline that you purchase from a gasoline station. Typically 2 stroke engines you have to mix some 2 cycle oil into the fuel to ensure proper lubrication of parts.

The 4 stroke engine uses the standard gasoline from the gas station, and typically the 87 octane will work fine. If the engine is a high compression engine, you'll have to go to a higher octane level, but they are all 4 stroke engines.

Answer 2

Depending what type of engine it is, regular gasoline will normally do. If it is an air cooled engine then a gasoline with a higher octane (supreme, gold , silver etc.) could be used but usually regular fuel is fine. An engine that is liquid cooled and is naturally aspirated can use a fuel with a regular octane rating too. Only high performance engines or engines that get really hot really need a higher octane fuel. Hope this helps.

Answer 3

it's usually called a 4 STROKE engine, instead of a 2 stroke engine commonly used in motorcycles

a 4 stroke engine uses the gas which you can get at your local gas station.

4 stroke engines are used in cars because it creates less emissions compared to the 2 stroke engine

the 2 stroke engine, commonly used in motorcycles, create more power, but more emissions too, but they use a mixture of gas and oil
