1. Emission and Deposit Formation in Direct Injection Stratified Charge SI Engines
Sammanfattning : A promising approach to increase the efficiency of the spark ignition (SI) engine is to inject the fuel directly into the cylinder to form a stratified charge. There is a potential to reduce the fuel consumption at low speeds and loads by 20 - 25% compared with conventional SI engines with stoichiometric homogeneous charge. LÄS MER
2. Chemistry of Combustion Products Investigation of Combustion Chamber Deposits Formed in a Gasoline Direct Injection Stratified Charge SI Engine
Sammanfattning : The aim of this work was to characterize deposits formed in the combustion chambers of a gasoline direct injection stratified charge SI engine. The engine was run with several types of gasoline fuels and a special reference engine oil. LÄS MER
3. Challenges and Advantages of Stratified Combustion in Gasoline Direct-Injected Engines
Sammanfattning : The modern world is based on an extensive transport network in which passenger vehicles play a major role. Although passenger vehicles have improved significantly in recent decades, they still contribute to the pollution of our environment and global warming. Consequently, new ways of reducing their emissions are needed. LÄS MER
4. Gasoline Engine HCCI Combustion - Extending the high load limit
Sammanfattning : There is an increasing global focus on reducing emissions of greenhouse gases.For the automotive industry this means reducing CO2 emissions of the vehiclesmanufactured, which is synonymous with reducing their fuel consumption oradapting them for using renewable fuels. LÄS MER
