Circuit for driving common rail diesel injectors 2020-36-0254
The injector driving strategy influences both the performance and the emission produced by internal combustion engines. The injector driving strategy is the intellectual property of the automotive industry; its disclosure is restricted to the automaker and the injection system supplier. The objective of this paper is to present a drive circuit for common rail diesel injectors. The circuit design is based on transient simulations using an equivalent virtual circuit, to be used on a test bench for injection strategies. The simulated electric current curve has been compared with experimental measurement under the same conditions in the projected circuit, the errors has remained at approximately 6%.
