Fuel injection system at Diesel engines

Diesel motor s izravnim ubrizgavanjem goriva krajem 20. stoljeća preuzeo je vodstvo i u automobilskoj industriji, zbog niže potrošnje goriva u odnosu na motore s komorom, te tako potvrdio da je najekonomičniji toplinski stroj. Kako su kriteriji o dozvoljenoj štetnoj emisiji ispuha bili sve stroži, uvedeni su sustavi koji elektronički upravljaju radom motora i elektronički reguliraju ubrizgavanje goriva pod nazivom EDC (elektronička kontrola). Kod njih su mehanički uređaji za reguliranje zamijenjeni mehatroničkim regulatorima pri čemu su zadržane mehaničke pumpe za ubrizgavanje. Kao rezultat visokog stupnja razvoja na mnogim tehničkim područjima pojavio se sustav s izravnim ubrizgavanjem goriva – Common Rail sustav.Diesel engine with direct fuel injection at the end of the 20th century took over leadership in the automotive industry due to lower fuel consumption compared to chambers engines, thus confirming that it was the most economical heat engine. As the pollutant emission allowance criteria were tighter, systems that electronically control engine operation and electronically regulate fuel injection called EDC (electronic control) were introduced. With them, the mechanical regulating devices are replaced by mechatronic regulators where mechanical injection pumps are retained. As a result of the high degree of development in many technical areas, a direct injection system has appeared - the Common Rail system
