The diesel fuel carburation process considerably reduces the pollutant emission from spark ignition engines, thereby making an important contribution to the current environmental problem. The high temperature needed for the carburation process is produced by the self-generated high exhaust temperature of the engine. This exhaust heat is fed to the external duct. The highly heated external duct transmits its heat to the internal duct, since this is enclosed by the external duct. The preheated air in the internal duct drawn in from the air filter mixes with the injected diesel fuel and vaporises to form a homogenous ignitable fuel-air mixture. In the working cylinder the fuel-air mixture is completely burnt. Due to this precise combustion of the diesel fuel, an environmentally harmless engine exhaust emission is produced with increased engine power and fuel savings.
