DARDANOS Controls for Electronic Fuel Injection
The DARDANOS range includes universal EFI control units for engines with electronically controlled injection systems. These solenoid valve control systems are primarily used to control the speed. They help to optimise fuel consumption and this, in turn, results in less environmentally harmful emissions. They can also be used for basic monitoring functions, thereby increasing the operational reliability and availability of engines.
- For diesel, gas & dual-fuel engines
- Precise injection control
- Configurable to suit specific applications
MVC 01-24
A solenoid valve control system for industrial diesel, gas and dual-fuel engines with a maximum of 24 cylinders. Enables up to seven precise injections per cylinder and stroke; large number of I/Os enables optimum engine operation and monitoring; can be used with any control system based on solenoid valves; combined with MEGASOL injection valves for gas injection systems. What’s more, up to 3 actuators can be actuated directly, for instance to control the air volume (throttle valve, turbocharger bypass, wastegates). It can be expanded as a redundant system for use in ship engines.

MEGASOL Gas Admission Valves
MEGASOL valves are designed to operate with a comparatively high differential pressure of supplying air and gas. They are characterized by excellent load response, precise dosage and individual adjustment of gas quantity for each cylinder. MEGASOL valves have a very low leakage when closed and are easy maintain.
- Precise metering of gas quantity for each cylinder individually
- Fast response and excellent load behaviour of engine
- Suitable for new engines as well as for retrofit solutions
- No risk of backfires

Engine Types & Applications
Gas Engines Dual-Fuel Engines
CHP GensetsSpeed sensors
Both inductive sensors and Hall sensors are available with different lengths and thread sizes. Thanks to their robust design, inductive sensors are ideal for use in harsh ambient conditions. Compared to inductive sensors, the advantage of Hall sensors is that the output signal is independent of the speed and the distance from the sensor.
Knock Sensors
HEINZMANN’s piezoelectric vibration sensors detect high-frequency vibrations that are typical of engine knocking. By detecting the knocking noises, the ARIADNE knock detection system can prevent damage to the engine.
