WebFeb 18, 2024 · The exhaust gas is substantially inert. Thus, introducing a portion of the exhaust gas into the combustion chamber of an internal combustion engine dilutes the mixture of fuel and air to be combusted, and resultantly lowers the peak combustion temperature and excess oxygen. WebOct 20, 2024 · As a result, the diluted mixture burns slower, lowering temperatures in the combustion chamber by almost 150°C. Consequently, reducing NOx production, for a cleaner more efficient exhaust. But, having a (EGR) valve can have a downside as well. Consequently, it leads to a gradual accumulation of carbon particles, inside the inlet. WebLow temperature combustion (LTC) is a flameless, staged burning of the fuel (gasoline, diesel, or biofuel) in an engine's combustion chamber at temperatures that are lower than what occurs during conventional engine combustion.
