Because they use spark plugs and associated parts to create a spark which ignites the fuel-air mixture in the cylinder whose combustion and expansion of gasses is what makes the engine run.

Why is stabil added to gasoline for small air cooled engines?

Stabil is added to gasoline in small air cooled engines to reduce heat that builds up.


What gasoline tho they use for small engines?

For the most part all small engines require 87 octane regular. Some 2 cycle engines require 89 octane gasoline. Refer to your owners manual.


What are the Uses of unleaded gasoline?

Unleaded gasoline is used as fuel for vehicles with spark-ignition engines, such as cars, motorcycles, and light trucks. It is also used in some small engines like lawnmowers and generators. Unleaded gasoline helps reduce harmful emissions and protect catalytic converters in modern vehicles.


Is it OK to use premium gas in small engines?

Most small engines are designed to run on regular unleaded gasoline; the higher octane premium gasoline may eventually be harmful to the engine.


Is diesel better then gasoline?

Not necessarily, they have different uses. Gasoline is better in small, high revving engines and diesel is much better for larger, slower engines in general.


Is diesel fuel the same as distillate?

No, 'distillate' is not the same as diesel fuel. It is more like kerosene and is used in engines that have spark plugs for ignition rather than high compression to ignite the (injected) fuel. Distillate engines often have a small gasoline tank so they will start col on gasoline and you switch it to distillate after it warms up.


Why are diesel engines so noisy when they are running?

Diesel engines are inherently noisy due to the method in which they burn fuel. Unlike spark ignition engines, compression ignition engines run much higher compression ratios, about 18:1 as opposed to gasoline engines which typically run a 10:1 ratio. This means that a diesel compresses a larger volume of gas into the same space as an gasoline engine of the same size, this compression heats up the air to such a high temperature that when the diesel fuel is injected into the cylinder it spontaneously explodes, releasing a lot more energy than the equivalent gasoline engine. the large amount of rapidly expanding gas is what causes the loud operating noise. Modern diesel engines can get around this by incorporating a small premixing chamber before the cylinder connected by a small passage. This slows down the explosion and makes the engine quieter and smoother.

How were your lives improved by the invention of gasoline?

Gasoline engines allowed the development of automobiles and trucks, which provide personal travel and simplify transportation for goods and services. Small gasoline engines power recreational vehicles (snowmobiles, jet skis, ATV's) as well as garden tools and emergency generators.


Can a helicopter use petrel?

Yes, may small helicopters have piston engines that use petrol (gasoline in USA )


What are the two types of hybrid car engines?

Typically the two types of engines deployed in the modern hybrid car is a small gasoline engine combined with an electric engine.


Are VW 1.9 liter TDI interference engines?

Gasoline engines can be designed so that even if the timing belt breaks, the valves will not contact the pistons, regardless of what position the camshaft stops in (a so-called non-interference engine). Not all gasoline engines are non-interference ... but they can be. This is impossible with a diesel engine because of the high compression ratio, and the small space between the piston and head in order to achieve that compression ratio. All 4-stroke diesel engines are therefore interference engines.
