Powergen engine control
Besides engines we supply systems that enable engines to operate efficiently in their specific applications – from airfilter .
Scope of supply power generation:
Gastrain
Airfilter
Gas mixer system
LAMBDA control system
Throttle valve
Speed governing system
Ignition system
Knock detection
Gastrain
A gas engine requires fuel to operate. This fuel must be offered to the gas engine clean, at the right pressure and safely. This is done by the gastrain.
Airfilter
To combust a fuel oxygen is required. This oxygen is in the air that surrounds us. To use the air the air needs to be clean before it can enter the engine. Therefore an air filter is placed to prevent dust and other harmful particles entering the engine. The air filter usually consists of a airfilter catridge holder, airfilter cartridge and connection material to the gasmixer system.
Gas mixer system
The gas mixer system enables the mixing of fuel gas and air into the correct ratio and creates a homogenous mixture which is ready for combustion. In a static version this mixing ratio is fixed. In a non static version this is called an air-fuel ratio mixer which needs a control unit to operate the ratio which is required.
LAMBDA control system (air/fuel ratio mixer and control system)
When gasses are subject to variation an air fuel ratio mixer and control system allows to compensate for the variations within a certain bandwidth. This ensures that the engine can still perform on power or emission levels when circumstances change.
Throttle valve
The throttle valve is used to regulate the amount of (fuel/air) mixture entering the engine. The higher the speed or load requirements get, the more mixture is required. The control of this throttle valve is done by the speed governing system.
Speed governing system
This system controls the throttle valve. This system consists of an actuator to operate the throttle valve and a control unit which controls the actuator. To match an operating speed or load required this system ensures that the engine gets the amount of fuel supply it needs to perform its task.
Ignition system
The combustible mixture is ignited by a sparkplug in the combustion chamber. This sparkplug must be ignited at the right time with the right energy and the right duration. This is managed by the ignition system. The ignition system generally consists of a sparkplug lead, an ignition coil which can convert the energy required for a spark, a rail where these ignition coils are mounted on which is mounted to the engine and a wiring loom connected to the control box.
Knock detection
Unwanted ignition of mixture in the combustion chamber is called knocking. Knocking is a phenomenon which is to be avoided because any ignition besides the one intended from the ignition system can cause damage to the engine. Utilization of knock detection can prevent damage from occurring by adjusting ignition timing or derating of the engine (or in severe cases stop the engine). Especially fuels that have a low methane number are susceptible for knocking.
