spark-ignition engine

Later spark-ignition engines developed from the 1920s could be directly coupled.

Some specific applications of small spark-ignition engines are not covered by the Regulations.

Gasoline (petrol) is a fuel for use in a spark-ignition engine.

Canada imported $471 million worth of small spark-ignition engines and machines in 2000.

The national emissions mark is required for small spark-ignition engines manufactured in Canada.

U.S. emissions standards for small spark-ignition engines have been in place since 1997.

Regulations for marine spark-ignition engines and recreational vehicles are under development.

A spark-ignition engine needs a particular air-fuel ratio in order to operate.

Small spark-ignition engines contribute approximately nine percent of mobile air emissions in Canada.

Pollution from small spark-ignition engines can be significant compared to automobiles which have been subject to emissions standards for over 30 years.

Like a spark-ignition engine, its fuel enters the cylinder premixed with air.

It represented the first use of direct gasoline injection on a spark-ignition engine used to power a road going vehicle.

For spark-ignition engines the fuel has an octane rating.

• large spark-ignition engines (covering industrial applications such as forklifts).

It is blended with conventional petrol, usually as a 5 % additive, and can be used in modern spark-ignition engines without modification.

As a result, carbon dioxide (CO2) emissions from small spark-ignition engines are expected to be reduced by about nine percent.

"The proposed regulations will reduce the level of smog-forming emissions from off-road small spark-ignition engines by about 44 percent."

Unfortunately, most microbially-sourced fuels can be used only as a small fraction of gasoline in conventional spark-ignition engines.

Planned vehicle and engine emission regulations for off-road machines powered by large spark-ignition engines are under development.

Spark-ignition engines typically operate on gasoline, compression-ignition on diesel fuel.

Canada has met all of its regulatory commitments except for the planned regulations to address emissions from marine spark-ignition engines, which are currently under development.

A four-stroke spark-ignition engine is an Otto cycle engine.

Smaller units were generally powered by spark-ignition engines, which were cheaper to buy and required less space to install.

Spark-ignition engine (commonly found as gasoline engines)

In spark-ignition engines the gases resulting from combustion of the fuel and air mix are called exhaust gases.
