In MADI, investigations are carried out in the field of diesel engine working
process perfection for complying with prospective ecological standards such
as Euro-6 and Tier-4. The article describes the results of the first stage of
experimental research of the influence of injection pressure up to 3000 bar
on working processes of diesel engine and its fuel system. Justification of
the design of a Common Rail injector for fuel injection under 3000 bar
pressure is presented. The influence of raising injection pressure (up to
3000 bar) on the fuel spray propagation dynamics is demonstrated. The
combined influence of injection pressure (up to 3000 bar) and air boost
pressure on fuel spray propagation dynamics is shown, including on engine
emission and noise.
