Description:

This is the world first in mass production Gasoline Direct Injection system which can reach 1000bar working pressure. Very high-pressure gasoline direct injection (GDI) can enable high efficiency and clean combustion while overcoming standard GDI drawbacks such as knocking and soot and improve the engine thermal efficiency. it is the must technical roadmap in order to meet the future E7/C7 emission standard, reduce fuel consumption and carbon emission. Marelli created a complete system consist of a pump, fuel rail, injector, and an electronic control unit (ECU) with software. This system has won the 2021 PACE award.

Unique advantages: 

•        World first in mass production GDI system reaching 1000bar working pressure

•        High efficiency and clean combustion, significant reduction of emissions

•        Reduction of engine knock, improvement of thermal efficiency, devoted to achieving carbon neutrality

•        Effective solution to improve substantially the efficiency of ICE, that can still be an important alternative in the evolution of mobility

Application:

It can be used on various Gasoline Direct Injection engine application, including hybrid, Plug-in Hybrid, it can reduce significantly the emission (especially the particulates) , inhibit the knocking and improve the engine thermal efficiency, this is particular sensible for hybrid applications.

Prospect:

Especially used for high thermal efficiency engine, it can also work with other engine technologies (e.g. super lean combustion, active pre-chamber technology), to further improve engine thermal efficiency up to 50%.
