Shut-Off Valve
� The shut off valve represents the first stage in the gas train.
� In addition to the ignition system, this device becomes the safety to shut down the
engine by simply cutting off the fuel supply.
� The gas inlet port is ¾” for the G914L04 or 1” for the G914L06 and TCG914L06
models.
Natural Gas Inlet

Pressure Regulator
� The “Zero” Pressure Regulator receives a gas pressure from 12” to 14” H2O and
reduces the gas pressure level to 0” H2O.
� Outlet pressure to the fuel stepper motor is preset and sealed to 0” H2O
(-0.25” to +0.25”) during the engine production and engine testing process.
� Inlet and outlet ports are 1.0” NPT thread.

Fuel Stepper Motor
� After the pressure regulator, the fuel stepper motor becomes the next component
of the fuel metering sub system. The stepper motor determines the mixture of the
air-fuel ratio.
� The motor gets the signal out of the Engine Control Module (ECM) and varies the
amount of gas mixed with air by the following venturi.
Pressure Regulator

Venturi Mixer (Carb)
� The venturi is the third and last subsystem of the fuel metering system.
� At this stage the gas gets mixed with the air and flows through the throttle into the
combustion area of the 914.
� In conjunction with the pressure regulator and the fuel stepper, the venturi
provides precise control of the desired fuel-air-ratio in response to the oxygen
sensor located in the exhaust system.

Throttle System
� After the venturi, the air-to-fuel mixture passes through the throttle, which
controls the quantity of air-fuel-ratio according to the load and speed of the
engine.
� The throttle has an effective diameter of 40 mm and is operated “fly-by-
wire”. The needed position / angle of the throttle valve is controlled by a
changing voltage from 0 to 12 Volt.
� The throttle opening position will be relayed to the Engine Control Module

Cylinder Head
914 Gas Emission Control System
Air-Fuel-Ratio and Ignition Timing
The G914 is equipped with an advanced monitoring and ignition system in order to run the air-
fuel-ratio precisely. This technology ensures minimized exhaust gas emissions and compliance
with the Environmental Protection Agency (EPA).
The air-fuel ratio quality will be monitored by the first oxygen sensor in the exhaust system,
which is located between the engine and the catalyst.
Exhaust gas quality will be controlled by the second oxygen sensor, mounted behind the
catalyst.
The key to the low emissions of any DEUTZ G914 is the close loop system managed by the
Engine Control Module. Ignition timing and air-to-fuel ratio are constantly monitored and

Engine Control Module. Ignition timing and air-to-fuel ratio are constantly monitored and
adjusted according to speed and load.
Utilized sensors consist of the following:
� Magnetic Pick Up speed sensor (MPU), located at the pulley and flywheel
� Manifold Absolute Pressure (MAP), inside the intake manifold, behind the throttle
� Pre Catalyst O2-Sensor (UEGO), between engine and catalyst
� Post Catalyst O2-Sensor (HEGO), after catalyst
� Oil Temperature (OILT), regular sensors comparable to Diesel Engines
� Lube Oil Pressure (LOP) , regular sensors comparable to Diesel Engines
� Cylinder Head Temperature (CYL) , regular sensors comparable to Diesel Engines
914 Gas Ignition System
Ignition Control
� The ignition timing will be constantly adjusted to the individual load and speed
under all circumstances; this process will be monitored by the central Engine
Control Module (ECM).
� The DEUTZ G914 is equipped with double high energy ignition coils. Each
unit supplies two spark plugs / cylinders with electric energy.
� Speed signal will be picked up magnetically at the flywheel. An additional
index hole provides information on the top dead center (TDC) of the

index hole provides information on the top dead center (TDC) of the
crankshaft, which is important for the ignition system.
914 Gas Exhaustgas After Treatment (EAT)
Catalytic Converter
� DEUTZ is using a 3-Way Catalyst for the EAT System of the G914
� The specified heavy duty catalyst from DCL is designed for tough applications,
such as underground applications.
� The Catalyst is used to reduced exhaust gas emissions:
� Nitrogen oxides to nitrogen and oxygen:
2NOX→ xO2 + N2

� Oxidation of carbon monoxide to carbon dioxide:
2CO + O2→ 2CO2
� Oxidation of unburned hydrocarbons (HC) to carbon dioxide and water:
