How do emissions differ in spark ignition and compression ignition?

What type of engine uses compression ignition as it has no spark plugs?

a diesel engine uses compression and has no need of spark plugs

What is the difference between a reciprocating internal combustion engine and compression ignition combustion engine?

Compression ignition is deisel. Otherwise, spark ignition is gasoline.

Why high compression ratios are not used in spark ignition engines?

spark ignition itself can easily burnt the air fuel mixture hence the high compression ratio is not needed.

Spark plugs cause the ignition in Diesel engines?

No, spark plugs do not cause ignition in diesels. The fuel compression causes ignition

In which step of the four stroke engine cycle does the spark plug initiate the combustion reaction?

Compression and ignition

Main advantages and disadvantages between compression ignition and spark ignition engines?

A spark ignition engine is a gasoline engine. A compression ignition is a diesel engine.basic difference between compression and spark ignition engine is ,compression ignition is a diesel engine. spark ignition is a gasoline engine.diesel engines compress the fuel to a point where the fuel explodes, thus giving ignitiongasoline does not compress to explosion, therefore it needs need a spark to ignite the fuelspark ign. is gasoline. comp. ign. is diesel.A compression ignition engine is typically a diesel. It compresses air so much that the heat from the compression is enough to cause the fuel to ignited once injected. A spark ignition engine is your average gasoline-burning car engine. It uses a spark plug to ignite the air/fuel mixture instead of relying on compretssion ignition.A compression ignition engine uses very high compression of the air to heat it self up and the fuel is injected into the cylinder which self ignites (a diesel engine is a compression ignition engine).A spark ignition engine uses a lower compression ratio and requires the use of a spark to ignite the fuel (a petrol engine is a spark ignition engine).Because the oils used for a diesel have a higher calorific value, they have a better fuel economy, They also do not need extra energy usage to keep the engine running, unlike the energy that is lost to power the spark plugs from the generator/alternator which is taken from the useful energy produced by the engine.

What is similar to a gasoline engine except it has no spark plugs?

A diesel engine has the same internal components and works off of compression ignition, not spark ignition.

What is the difference between a SI engine and a CI engine?

An SI engine ignites the fuel with a spark (SI = Spark Ignition) whereas the CI engine ignites the fuel with heat generated from compression (CI = compression ignition)

Ignition will not turn over?

The engine needs fuel, compression and spark (ignition) to run, you are missing one of those.

What is spark ignition or Diesel?

spark ignition engine is also known as petrol engine. but in diesel engines the fuel is burnt due to the high compression of air.so there is no need of spark plug

High Compression ratio not used in spark ignition engine?

S.I Engine lower compression Ratio is 6 to 11
