Diesel Knock |
|||
| The fuel accumulated during the ignition delay period is burned at one time during the flame propagation period. Thus the pressure inside the combustion chamber rises sharply. The pressure inside the combustion chamber rises sharply in proportion to the amount of the fuel injected during the ignition delay. This pressure wave causes the engine to vibrate and make a noticeable noise. This is called as diesel knock. The diesel engine uses a self-ignition combustion system, so to a certain extent, diesel knock is unavoidable. |
