Smart injector technology

L’IQ – Intelligent injectors:
A new era in large-engine fuel injection

We have developed smart injector technology – the L’IQ Intelligent Injector – featuring a pressure sensor close to the nozzle which can monitor the injector’s function and condition and communicate its status to the outside world.

FEATURES & FUNCTIONALITY

Due to their modular design, we are able to offer common-rail systems for the most varied engine types and for engine sizes from 100 to 3,920 kW/cylinder. The systems are suitable for heavy fuel oil and diesel.

Since the launch of the first electronically controlled common-rail fuel injection system in 1997, system pressure has more than doubled, primarily due to measures to reduce emissions. Increasingly high injection pressures are challenging for mechanical components. The requirement to ensure compliant emissions over the entire effective life of a fuel injection component represents a further challenge.

With these issues in mind, we have developed smart injector technology – the L’IQ Intelligent Injector – featuring a pressure sensor close to the nozzle which can monitor the injector’s function and condition, and communicate its status to the outside world.

A closed control loop can be built in to monitor the start and end of injection in view of stabilizing the duration of injection over the effective life of the injector, and therefore enabling a timely response to symptoms of wear and tear.

The L’IQ Intelligent Injector ensures optimized utilization of fuel injection components over time.

The new L’IQ injectors are configured to be smart and communicate with their environment. This opens up the potential for a number of components within a system to exchange data and information, which in turn will lead to optimization of the entire system, sub-systems or superordinate systems.

In the future, fuel injection along with combustion will be monitored by electronic systems. This will enable the thermodynamic optimization of combustion based on fuels with strong variations in characteristics, as well as the early detection of unforeseen fuel injection behavior or even engine failure.

With the intelligent injector, the cornerstone is being laid for the digitalization of individual fuel injection components – and for the ongoing evolution of integrated injection technology.
