benzineinjectors
Benzineinjectors are components of modern fuel-injection systems that meter precise amounts of gasoline and deliver them to the engine where they mix with air for combustion. They replace older carburetors and are used in most petrol engines worldwide. Their accuracy and spray characteristics influence power, fuel economy, and emissions.
Two main configurations exist: port fuel injectors, which spray gasoline into the intake port where it mixes
Construction and operation: Most injectors consist of a nozzle, a valve, a coil or actuator, a housing,
Control: The engine control unit (ECU) determines injector on-time from sensor data (engine speed, load, air mass,
Maintenance and reliability: Injectors can clog from varnish and deposits, especially with ethanol-containing fuels. Symptoms include
Modern engines have benefited from precise injector control, enabling lean burn strategies, turbocharged efficiency, and lower
