#CMT# #/CMT# The chamber has a fuel injector (3) placed in a cylinder head (1), and a piston (2) slidably mounted in a cylinder along an axis (Z). The piston has a front surface presenting a tulip (22) defined between a central dog-pilot point (21) and a peripheral crown (23). The front surface and the cylinder head provide a radial Venturi shape to the chamber, where the shape presents convergent and divergent zones (C, D) separated by a collar (K). A heater plug (6) is placed in the cylinder head and comprises a heat end (60) placed in the collar. #CMT#USE : #/CMT# Sonic throat combustion chamber for a four stroke, internal combustion, compression ignition heat engine such as cold starting oil engine (claimed) e.g. direct injection oil engine. #CMT#ADVANTAGE : #/CMT# The heater plug rapidly triggers self-combustion of the fuel. The configuration of the combustion chamber improves cold starting capacity of the engine. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a semi axial sectional view of a combustion chamber.
