Why do gasoline engines need spark plugs?
Gasoline engines use a spark plug to create the explosion. That higher compression ratio means higher efficiency from the engine, or more miles from the fuel. Advantage: diesel. In gas engines, the fuel is injected earlier, and the air is kept cooler with a lower compression ratio.
Which type of engine uses spark plug?
Spark plugs are used in the petrol engines to ignite the air fuel mixture whereas in diesel engines the presence of spark plugs is not necessary. Technically petrol engines are called as spark ignition engines ( SI ) and diesel engines are called as compression ignition engines (CI ) .
Do 2-stroke engines have 2 spark plugs?
There are 2-stroke, compression-ignition (Diesel) engines that, by definition, don’t employ spark plugs.
Why is a spark plug used in a petrol engine?
It does not produce enough heat so that the air and fuel mixture get ignites, therefore spark plug is needed in Petrol engine. Although , In case of diesel engine, the air is compressed up to 14 to 25 times of their volume. This much compression causes air to get very hot at least 500°C (1000°F) or mo… Loading…
What’s the difference between glow plugs and spark plugs?
All combustion engines need three things: fuel, air and heat or an ignition source. Both spark plugs and glow plugs are the ignition source in a combustion engine. So, what’s the difference? The short answer is the type of engine they’re found in. Spark plugs are only found in gasoline engines and glow plugs are in diesel ones.
How many spark plugs does a gasoline engine have?
Spark plugs are essential components in a gasoline engine because it is required to get the car moving. How many spark plugs does a car have if it’s that important? The answer is 4 for the 4cylider engine, 6 for V6, 8 for V8 it goes on that sequence.
How does a diesel engine use a spark?
A Diesel engine IS a compression-ignition engine. Instead of using a spark to ignite fuel like a gasoline engine, it uses the pressure and temperature reached during compression of the intake gas to ignite the fuel.

Why is the gas not reaching the spark plug?
More powerful mowers, such as ride-along lawn mowers, make use of fuel pumps to pump gas into the engine – instead of the gravity-feeding system that’s common in most push-along mowers. If the filters are clogged, your lawn mower won’t start because gas will not reach the spark plug.

Is it possible to use petrol without spark plugs?
My take on using petrol without spark plugs is maybe mixing it with a bit of diesel or some other kind of higher-carbon fuel to act as a stabilizer. Would that be possible? You get the explosive/ fast reactive power of a petrol engine without the need for spark plugs which can fail. There are already gas direct injection cars in production.
