Effect of fuel injection timing and pressure on combustion, emissions and performance characteristics of a single cylinder diesel engine.

Highlights: [•] Fuel injection pressure & timings affect engine performance, emissions and combustion. [•] Rapid combustion, higher cylinder pressure & ROHR at advanced injection timings. [•] Superior performance at lower FIP giving lower BSFC & emissions, & higher BTE. [•] Emission characteristics improve with advanced fuel injection timings. [•] Particulate number concentration in a CI engine increases with increasing engine load. [Copyright &y& Elsevier]
