![]() The only correct cure is a set of cylinder heads that incorporates the latest improvements to mixture motion. Perkins atomizers or injectors and the replacement nozzles with mechanical or electronic control that offer single or multi-spray patterns. When good choreography of swirl and quench doesn't happen, detonation does. Charge that is trapped between the piston and the cylinder head deck is squished into the open part of the combustion chamber at the last moment before ignition, giving the charge one last good chance to mix. Quench is another related action that occurs just at the moment the piston reaches TDC. The movement of air and fuel through the port, valve pocket, and combustion chamber is complex, and if the fuel cannot mix evenly with the air through a process called swirl (tumble in the case of a four-valve engine), poor performance and detonation will be the result. ![]() I've found that most cases of detonation can be traced to a combustion regime that tempts fate through port flow that causes separation of the fuel from the air. Testing Diesel Fuel Injectors for Peak Performance You will need a bench mount pressure release tester to do this yourself. All the fixes we've mentioned thus far are what I like to call "downstream" fixes, meaning they are more like a bandage than a real cure.
