In another study, Rychter et al [5] observed that rate becomes so high that the overall proces is limited the use of a catalyst in an SI engine resulted in the by the rate of species tranport between the bulk gas extension of the lean misfire limit and a significant flow aid the catalyst surfae. This is known as the m reduction in the cycle to cycle pressure variations, transfer limited regime.…”

“…Catalytic combustion has already been applied to reduce NOx emissions below 1500 o C in furnace burners and gas turbine engine combustors. However, catalytic combustion is minorly examined in the transportation sector due to the additional mass, bulk catalysts can add to the system [24][25][26]. Today, this disadvantage is overcome by the progress in nanoscience and nanotechnology to formulate nanosized catalysts whose enhanced catalytic activity requires small amounts.…”

In this work, the effect of the nanosized CZA2 (cerium-zirconium-aluminium) on the performance and emissions in a two-cylinder indirect injection (IDI) diesel engine, was studied. CZA2 was dispersed in diesel (D100) and waste cooking oil and tallow origin biodiesel-diesel blends (B10, B20, B30) and tested at different engine loads and constant speed. The nanocatalyst (CZA2) increased the brake specific fuel consumption (BSFC) and decreased the brake thermal efficiency (BTE, %) of all tested fuels, at all loads, except B20 at the lowest load. CZA2 reduced nitrogen oxides (NOx) from D100 at low and high engine loads, as well as carbon monoxide (CO) and unburned hydrocarbons (HC) at medium and high tested loads. The dispersion of CZA2 promoted the combustion of the biodiesel blends by almost eliminating HC while reducing NOx and CO emissions at various loads. Thermogravimetric analysis (TGA) coupled with Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy revealed that the addition of CZA2 in diesel and biodiesel under pyrolysis and oxidation conditions resulted in the presence of saturated species like ketones and final oxidation products such as CO 2 , supporting their improved combustion and emissions' reduction in the engine tests.

“…Thereafter, as the need to improve the combustion process in highly diluted conditions became more critical, many of the technological advances focused on using other strategies to complement the passive pre-chamber system. One example from the early 1980's is the lean-burn SI engine with a catalytic prechamber investigated by Rychter et al [99]. The cylinder head configuration with the passive catalytic pre-chamber is presented in Figure 2.13.…”
