Indians For Guns

My humble query before all Gurus: What does dieseling the gun means? How it is done? Is it safe?

Dieseling in an air rifle is when the oil inside the chamber / gun detonates due to compression. It increases the pellet velocity and will in the long run damage the breach seal and the piston seal. You can voulntarily cause dieseling by adding a drop or two of combustable liquid in the hollow behind the pellet.

Thanks a lot and regards.

It is called "dieseling" because diesel engines do not have spark plugs and simply compressing diesel vapour in air will make it burn and explode. Compounds similar to diesel - like oils will cause dieseling when compressed in an air rifle. Dieseling is noisy, smelly and useless and I would not recommend deliberately causing it in an air rifle for any reason.

Having said that, a well known refernce book on air rifles claims that some degree of dieseling is invariably present in every normal air rifle and this is proved by a specially built mechanism to document that. But still - deliberately causing dieseling is unproductive and damaging.

Thanks a lot.
