1. Emission and Deposit Formation in Direct Injection Stratified Charge SI Engines
Abstract : 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. READ MORE

2. Low Emission Concepts for Diesel Engines
Abstract : In the recent past, the Diesel engine has been improved considerably in the areas of performance, fuel efficiency and exhaust emissions. In Europe, these improvements have resulted in a strong increase in the sales of passenger cars equipped with a Diesel engine. READ MORE

3. Experimental and kinetic studies of H2 effect on lean exhaust aftertreatment processes: HC-SCR and DOC
Abstract : With a growing concern to lower greenhouse gas emissions from road transportation, lean burn and diesel engines will keep playing an important role in the future. Development of a highly efficient and durable process to reduce NOx to N2 becomes a challenging issue especially in the presence of ample O2 concentration as in lean burn exhaust. READ MORE
