Abstract
An internal combustion piston engine has one or more cylinders each having a main combustion chamber and an auxiliary combustion chamber connected by a torch nozzle. Exhaust gases from the main chamber are used to heat the intake mixture for the auxiliary combustion chamber. Contiguous thin wall pipes, one carrying hot exhaust gases and one carrying a rich mixture for the auxiliary chamber, are both enclosed within a thick wall outer housing. A riser for the auxiliary intake pipe is also enclosed within said housing. The thin wall exhaust pipes join an exhaust chamber secured to the thick wall housing at a central location to minimize deformations caused by thermal expansion.
