OPERATION PRINCIPLE,
LEAN-BURN GAS ENGINE
Introduction
The Bergen engine lean burn spark ignition (s.i. gas
engine operates according to the lean-burn Otto
cycle, i.e. a lean mixture of gas and air is compressed
and ignited by an electric system.
A lean-burn engine operates at a.e.r’s (air excess
ratios , of 1.8 and higher, and as the illustration
shows, this gives increased power, efficiency and
reduced NOx-emissions.
To achieve this, a special combustion system has
been developed that gives a strong increase in
ignition energy capable of firing such lean mixtures
reliably. Also, a highly efficient turbo-charging
system is used to take advantage of the possible
power increase offered by the extended knock limit
of lean mixtures
Principle of operation in brief
Air is drawn in by the turbocharger, through the
charge air cooler and into the cylinder. A timed
mechanical gas valve injects gas under over-pressure
into the inlet air stream to ensure a homogeneous
and lean mixture of air and gas.
Air flow is controlled by the variable turbine geome-
try, VTG, while gas flow is controlled by mechanical
valves before each cylinder.
The gas pressure is set electronically by the pressure
regulating valve on the fuel gas supply module
ahead of engine.

An air flap for each cylinder restricts the air supply
during start-up and low load operation.
As the pressure in the cylinder is low, gas is
admitted into the small pre-chambers - one in each
cylinder head, electronically controlled by the pre-
chamber pressure unit. During compression, the
lean charge in the cylinder is partially pushed into
the pre-chamber, where it mixes with the pure gas
to form a rich mixture that is easily ignited by the
spark plug. This powerful ignition energy from the
pre-chamber ensures fast and complete combustion
of the main charge in the cylinder.
Advanced electronic engine management ensures
the operating parameters of the engine are
adjusted and optimised in relation to each other.
The system sets the optimum main, and pre-
chamber gas pressures, the AFR (air/fuel ratio , the
fuel rack position, the ignition timing and air throttle
position.
The alarm and monitoring part of the system
features many built-in safety functions. It combines
safe operation with high availability, protecting the
engine and signalling any fault. It includes a mis-
firing detection system based on analysing different
operational parameters and a knock
detection system. The system detects and eliminates
knocking individually for each cylinder.
The complete engine management, control and
monitoring system fits into a cabinet next to the
engine and communicates with the plant control
through one simple cable.
