Injector Driver Circuit for Diesel Engines

As global fuel consumption increases, the requirements for the Environmental Protection Act and policies are getting more rigid. Therefore, the fuel economy and emission performance of internal combustion engines need to be continuously improved. Traditional mechanical fuel injection systems in diesel engines have a long delay due to their mechanical inertia; hence, they cannot meet emission requirements, such as flexible fuel injection timing inside the diesel engine. Thus, electronic control technologies were invented for diesel engines to overcome this shortcoming, as they noticeably improve engines’ performance and reduce total carbon emissions. The Electronic Fuel Injection (EFI) system also allows for flexible control of the fuel injection rate, which makes it simple to modify the diesel engine’s performance to meet predetermined vehicle emission targets. It is very important for the injector to have a flexible control circuit.
