Summary: | The performance of a Diesel engine is influenced by various parameters like
compression ratio, fuel air ratio, speed etc... The performance of a diesel engine increases with
increase in compression ratio. Variable compression technologies in IC engines are used to
increase fuel efficiency under variable loads. Cooled exhaust gas recirculation is a common way
to control in-cylinder NOx production and is used in most modern high speed direct injection
diesel engines. However the effect of EGR on performance, combustion and emissions
production at different compression ratios are difficult to depict. In the present work an attempt
was made to study the effects of cooled exhaust gas recirculation on performance, combustion
and emissions of a variable compression Diesel Engine. The test was conducted at different
compression ratios with different loads (no load to full load) and for different EGR rates
(0-10%). |
