Engine speed and load have great influences on emissions when operating on diesel-GTL blends and diesel fuel in the turbocharged diesel engine.
      
Cycle fuel energy distribution and combustion characteristics of early in-cylinder diesel homogenous charge compression ignition (HCCI) combustion organized by modulated multi-pulse injection modes are studied by the engine test.
      
Study on emissions reduction of DMCC engine with oxidation catalyst
      
However, HC, CO and NOx were dramatically decreased with a catalytic converter, and PM was also decreased compared with that of diesel engine.
      
The testing results illustrated that, combined with oxidation catalyst converter, DMCC could improve engine emissions.
      
Effects of compression ratio on the combustion characteristics of a homogeneous charge compression ignition engine
      
The effects of homogeneous charge compression ignition (HCCI) engine compression ratio on its combustion characteristics were studied experimentally on a modified TY1100 single cylinder engine fueled with dimethyl ether.
      
The results show that dimethyl ether (DME) HCCI engine can work stably and can realize zero nitrogen oxides (NOx) emission and smokeless combustion under the compression ratio of both 10.7 and 14.
      
Study of combustion and emission characteristics of turbocharged diesel engine fuelled with dimethylether
      
An experimental study of a turbocharged diesel engine operating on dimethyl ether (DME) was conducted.
      
The combustion and emission characteristics of the DME engine were investigated.
      
However, the maximum cylinder pressure, maximum pressure rise rate and combustion noises of the DME engine are lower than those of diesel.
      
Compared with the diesel engine, NOx emission of the DME engine is reduced by 41.6% on ESC data.
      
In addition, the DME engine is smoke free at any operating condition.
      
Application of micro-genetic algorithm for calibration of kinetic parameters in HCCI engine combustion model
      
It is concluded that though the performance of an air-powered engine is inferior to that of the traditional inert combustion engine, an airpowered vehicle is fit for future green cars to realize the sustainable development of society and environment.
      
Selective catalytic reduction of NOx from exhaust of lean-burn engine over Ag-Al2O3/cordierite catalyst
      
The catalyst performance was tested on a real lean-burn gasoline engine.
      
Addition of diesel fuel and waste engine oil to soil was found to stimulate hydrocarbon-oxidizing microorganisms.
      
A Fuel-Optimal Control by the Velocity Vector of a Multi-Engine Flying Vehicle in the Base of Engine Velocities
