“…All three strategies were found to be equally effective with temperature rise attributed to an increase in the in-cylinder heat release. Singh et al 7 and Joshi et al 8 describe commonly implemented methods for increasing exhaust temperatures by injecting diesel fuel directly into the exhaust upstream of a diesel oxidation catalyst. Researchers including Brück et al 9 have also tried, with little success, using electric heaters to increase exhaust gas temperatures.…”

“…1 is the schematic plot of the connection between the burner and engine. The pre-DOC can decrease the emission of HC and CO effectively during the operation of the diesel engine [4]; the DOC which is installed at the back of the burner has two advantages: On one hand, the burner can provide the working conditions for the DOC; in other words, the burner can be used to increase the exhaust temperature to DOC ignition temperature; On the other hand, combined heating-up can be realized by burner heating together with DOC catalyzed reaction heating, which provides the system with adjustable heating capacity in a relatively large range. The burners are mainly consisted of two steel drums, the internal and external steel drums.…”

“…Hydrocarbon dosers can also be used to inject fuel upstream of the DOC. 16,17 Roberts et al 18 experimentally observed a 30°C-80°C increase in engine outlet temperatures, and predicted up to a 100°C increase, via early exhaust valve opening (EEVO), at the cost of reduced brake thermal efficiency (BTE), and predicted that the engine outlet temperatures of many low load operating conditions can be increased above 250°C. Bharath et al 19 concluded from simulations that EEVO and exhaust cam phasing yield higher DOC conversion efficiencies with a deterioration in fuel economy.…”
