The Knocking in the Gas Dual-fuel Engine with Liquid LPG Injection into the Intake Manifold
Original language description
This article deals with a detection of the knocking in the gas dual-fuel engine converted from the original Cummins diesel (compression ignition – CI) engine. The dual-fuel engine is equipped with a Solaris (LPG-diesel) control system that adjusts the amount of LPG with diesel fuel to retain the same power as the original diesel engine. The maximal percentage of LPG supplied to the dual-fuel engine depends on the engine operating mode and prevents detonation in the engine cylinders. The combustion process of the fuel content and the detection of the knocking were checked by high-pressure indication in the cylinder. The knock-peak method is commonly used to detect knocking by the maximum pressure variation in working cycles. This is the absolute value of the maximum pressure oscillating at the high-pass filtered signal. The knock-peak limit is found to be 5 bar on the engine with Cummins dual-fuel using the knock-peak method. In general, this method can quickly detect the phenomenon of knocking and adjust the amount of LPG injection for improving engine power and reducing emissions.
