AN INTERNAL COMBUSTION ENGINE

摘要

In a V-engine a reactor (24; 24') for reducing the content of undesired compounds in the exhaust gas, such as NOx, is disposed between the two rows of cylinders (4). With this positioning the reactor does not occupy space in the engine room around the engine and at the same time the reactor is kept hot by the radiation and convection heat generated by the engine when the exhaust gas is not flown through the reactor. The reactor (24') may be integral with the exhaust gas receiver (18') of the engine, preferably so that the internal cavity of the receiver is separated from the reactor by means of a partition wall (28'), thereby making it possible to pass only exhaust gas through the reactor when there is a need for purification of the gas.
