Abstract

The invention discloses a method for adjusting detonation, which comprises the following steps: first, obtaining detonation test signal and detonation threshold value, then, affirming detonation strength according to the detonation test signal and the detonation threshold value, last, obtaining the ignition delay angle corresponding to the detonation strength, adjusting ignition time according to the ignition delay angle. The invention also discloses an adjusting device of the detonation, which comprises a detonation test signal generation unit, a detonation threshold value generation unit, an ignition delay angle acquisition unit and an adjusting unit. The invention affirms the detonation strength according to the detonation test signal and the detonation threshold value and adjusts the ignition time according to the detonation strength corresponding to the ignition delay angle, which makes the detonation of different strengths do fitful ignition time adjusting, further, the detonation occurrence can be inhibited effectively and the engine capability and the motor efficiency can't be reduced.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to a knock adjustment device and method. Background technique [0002] When the combustible mixture of the internal combustion engine is ignited by the high-pressure spark, the burning flame centers on the spark and spreads outward, igniting all the mixture in the combustion chamber. If before the flame arrives, the remote mixture is compressed due to the pressure of the gas expansion after combustion, resulting in a reduction in volume and an increase in temperature and pressure, so that a part of the mixture is compressed before the flame reaches the place. The temperature has reached the self-ignition point, and this part of the mixture will ignite by itself after reaching the self-ignition point, and spread outward rapidly. When its flame wave meets the normal combustion flame wave, it will produce violent gas vibration and form a detonation. [0003] The de...
