The invention discloses a diesel engine system with resonance air intake, which comprises an air compressor, an air intake main pipe, a diesel engine and a resonance device. The compressor is used to input air to the diesel engine system. The intake manifold communicates with the compressor. The diesel engine has a plurality of cylinders, and the plurality of cylinders are all connected to the intake manifold, and the plurality of cylinders are arranged in parallel. The resonant device is arranged at the end of the intake manifold away from the compressor, the resonant device includes a cavity, the cavity has an open end and a closed end, and the open end communicates with the intake manifold. The resonant device also includes at least two resonant valves, at least two resonant valves are openably and closably arranged in the cavity, so that the space in the cavity communicated with the intake manifold forms a resonant cavity. According to the diesel engine system with resonant intake air of the present invention, a resonant device with closed end is provided, and the intake pressure wave generated by the diesel engine can enter the resonant device and reflect to form a resonant wave, and the resonant wave can at least partially offset the intake pressure wave, and then Improve the intake consistency of each cylinder of the diesel engine.
Description
technical field [0001] The invention relates to the technical field of marine diesel engines, in particular to a diesel engine system with resonance air intake. Background technique [0002] At present, most marine diesel engines are multi-cylinder diesel engines, but the applicant has found that the intake air of multiple cylinders is different from each other, that is, the current multi-cylinder diesel engines have the problem of poor intake consistency. [0003] Specifically, each cylinder has a certain difference in the amount and pressure of the intake air, resulting in a different combustion rate for each cylinder. At present, there are generally two ways to improve the consistency of each cylinder. One is to realize the adjustable fuel injection timing and pulse width of each cylinder through the common rail fuel injection system or electronically controlled unit pump; Throttle valves are installed on the intake manifold of each cylinder to adjust the intake air volu...
