Gas Mixer

Features
Mixes gas and air to a very
homogenous mixture

DATA SHEET

Automatic metering of the
gas at any air flow according to Bernoulli’s law

Description

Cost effective and maintenance-free fuel system
component without moving parts

The gas mixer is an indispensable
component of the fuel system.
Whilst the throttle valve controls
the quantity of the mixture, the
mixing unit takes care for quality of
the mixture.

Very low pressure drop
due to the almost ideal
shaped Venturi insert

HEINZMANN mixers provide a
very homogeneous air and gas mixture and an optimal Air to Fuel Ratio (AFR)
over the entire speed and load range of the engine. HEINZMANN also can supply the remaining components of the fuel system such as main adjusting screw,
zero pressure regulator, throttle valve, speed and load control, AFR controls for
stoichiometric as well as for lean burn, adaptors, levers etc..

Power at draw-through carburetion. In blow-through application the output will be 50
% to 150 % higher, dependent on the boost pressure

** Power at an Air to Fuel Ratio of about 1,6

Technical data
Í Operating temperature: -20 to +150 °C
Í Max. boost pressure: 4 bar abs.

The carburettors can be
configured as draw-through
as well as blow-through
The carburettor models
are also available for dual
gas, EGR and low calorific
gasses
Supplied with balance
line connector in order to
compensate for air filter
restriction
For corrosive gases the
components are also
available in anti-corrosive
versions
The mixer insert can be
configured and removed
by the customer
