1. Transient Air to Fuel Ratio Response in a Fuel Injected S.I Engine
Sammanfattning : Future emission standards make it necessary to focus on the conditions under which engine emissions are produced, especially before the catalyst light off. During practical driving conditions, such as those represented by the FTP 75 test cycle, the engine is operated very much under transient conditions regarding load and speed. LÄS MER
2. Studies of a Heavy-Duty Diesel Aftertreatment System Based on the NOX Storage and Reduction Technology
Sammanfattning : The legislative limits for NOX emissions in the exhaust gas from heavy-duty diesel engines will be decreased in the European Union from today 3.5 g/kWh (Euro IV) to 2.0 g/kWh in 2008 (Euro V). In the USA and Japan a similar trend can be seen. LÄS MER
3. Experimental Investigations on Natural Gas-Diesel Dual Fuel Combustion
Sammanfattning : Natural gas has been traditionally applied in spark-ignited combustion engines due to similar combustion characteristics for methane gas and gasoline. However, spark ignition requires a low compression ratio to avoid knock problems and therefore, gas engines have lower efficiency than diesel engines. LÄS MER
4. Multiple Diesel Injections - Spray Behaviour and Fuel Injection System Dynamics
Sammanfattning : .... LÄS MER
5. Methanol Diesel Dual Fuel Direct Injection in a HD-CI Engine
Sammanfattning : Laws concerning emissions from heavy duty (HD) internal combustion engines are becoming increasingly stringent. New engine technologies are needed to satisfy these new requirements and to reduce fossil fuel dependency. LÄS MER
