Particulate emissions from a highly boosted gasoline direct injection engine

Influence of Three-Way Catalyst on Gaseous and Particulate Matter Emissions During Gasoline Direct Injection Engine Cold-start

The development of gasoline direct injection (GDI) engines has provided a strong alternative to port fuel injection engines as they offer increased power output and better fuel economy and carbon dioxide emissions. However, particulate matter (PM) emission reduction from GDI still remains a challenge that needs to be addressed in order to fulfil the increasingly stricter environmental regulatio...

Studying Simultaneous Injection of Natural Gas and Gasoline Effect on Dual Fuel Engine Performance and Emissions

According to the Global Fuel Crisis, it seems necessary to use alternative fuel instead of gasoline. Since the natural gas is cheaper, have higher frequency than gasoline and less pollution, it is a suitable fuel. Many efforts have been done in order to replace gasoline with natural gas. One of the methods is to inject natural gas and gasoline fuel simultaneously and to use the benefits of both...

Characterisation of Particulate Matter Emitted from Aviation Gas Turbines and Spray-Guided Direct Injection Gasoline Engines

Effect of Injection Characteristics on Emissions and Combustion of a Gasoline Fuelled Partially-premixed Compression Ignition Engine

Conventional compression ignition (CI) engines are known for their high thermal efficiency compared to spark ignited (SI) engines. Gasoline because of its higher ignition delay has much lower soot emission in comparison with diesel fuel. Using double injection strategy reduces the maximum heat release rate that leads to NOx emission reduction. In this paper, a numerical study of a gasoline fuel...

Modeling and Programming for a Computer Controlled Direct Gasoline Fuel Injection System of SI Engine

A computer controlled direct gasoline fuel injection (DGI) system has been modeled, programmed and constructed for a four-stroke SI engine. Locally available materials have been used for this experimental model. All the old model vehicle were equipped with carburetor for air fuel mixing and later on electronic fuel injection system has been introduced for maintaining better air fuel ratio and m...
