Dosing Strategy

Urea dosing strategy for SCR is studied for a diesel engine fuelled with bio-diesel BD20. Bio-diesel BD20 is consisted of biofuels made from waste cooking oil and national V diesel, and biofuels accounts for 20% by volume. The results show that, bio-diesel engine torque decreases by a maximum of 0.55%, brake fuel consumption rate increases by a maximum of 0.53% ,when the urea dosing strategy is adjusted and the engine and SCR are not changed. ESC tests show that, the maximum of NOXconversion ratio is 95%, the minimum is 57%, and the average value is 74% under ESC 12 conditions except idling, the maximum of HC decrease ratio is 74%, the minimum is 35%, and the average value is 55%, when the urea is dosed. NOXemission is 1.55 g/(kW·h) in ESC test, NOXemission is 2 g/(kW·h) in ETC test, and NH3slip is lower than 10×10-6, which proves that the NOXemission from the engine fuelled with BD20 can meet national emission standards V by adjusting the urea dosing strategy.

Relationship Of

For the growing importance of future emission restrictions and the expanding requirement for a better fuel economy, the internal combustion engines are forced to be improved for the high strengthening direction. However, the heat loads of the engine is increasing according to the increasing of engine speed and power density, hence, the cooling system is faced to more challenge. For the cooling system is one of the key system which has more effect on the engine efficiency, fuel economy, and exhaust heats; optimize the matching control cooling system becomes one of the key technology to improve the engine performance. In this paper, several overall schemes of the cooling system are analyzed and discussed, and then one design scheme is determined to the optimal for the current diesel engine. A whole engine system is established by the software GT-Power, and the cooling system in the engine system is established by GT-Cool based on the above optimal scheme. During the simulation, the influence on the heat dissipating capability brought by the control parameters, injection advance angle, power, and torque are investigated. At last, the requirement of the heat released under full conditions is analyzed, and the relationship of the fuel consumption and the control parameters is investigated.
