"Detonation" is the term used in chemistry to describe the combustion behavior, and "knock" is the older and more-commonly used word in the automotive industry. Either is OK to use, and commonly found inASEmaterials. Detonation is when the air : fuel mixture burns at an extremely fast rate...
Detonation is when the air : fuel mixture burns at an extremely fast rate due to combustion chamber conditions resulting in a sharp rise in cylinder pressure and temperature. Detonation can vary in intensity from light, moderate, to severe depending on several factors. Here’s a more technical ...
The knock-in mice also displayed clear sensory defects, while no abnormalities in the motor performance were observed. In addition, accumulation of mitochondria and an elevated energy metabolic state was observed in the knock-in mice. Taken together, our study indicates that the Dhtkd1Y486* ...
Alzheimer’s disease (AD) is one of the most prominent age-related diseases and the major cause of elderly disability, with progressive impairments in memory, personality, and other cognitive functions. AD has brought the heaviest social burden to the modern aging society.1,2The pathological hallm...
The muscle-specific kinase (MuSK) was originally proposed to mediate the signal from the motor neuron-derived synaptogenic factoragrinto cluster AChRs at the muscle end plates and induce postsynaptic differentiation (McMahan, 1990; Sanes and Lichtman, 1999; Valenzuela et al., 1995). The central...

The most common things to make a knocking sound areexhaust leak(rulled out, we think) valve train (excessive clearance, either out of adjustment or leaky lifter, or flat cam) or a connecting rod lower bearing. A good clue here is that the noise happens when the motor warms up. The oi...
An electronic control unit (7) is determined on the basis of an output signal of a knocking sensor (79), which a vibration event in the motor (1) detects whether a knocking episode takes place, and changes of a motor control amount based on the result of the knocking determination. When...
