If gasoline is injected only in the 3rd stroke of a four-stroke engine, the combustion process will not be efficient. This is because the fuel needs to be present in the cylinder during the compression stroke (2nd stroke) to mix properly with the air for combustion. Injecting gasoline only in the 3rd stroke may result in incomplete combustion, reduced power output, and increased emissions. It can also potentially damage the engine due to irregular combustion patterns. **
