Vehicles The development of the NONOX1 engine started in

1996 with the formation of the NONOX company.

The company developed and built its own engine

test bench facility and is therefore independent to

develop and adapt new technologies. NONOX

employs a powerful team of highly skilled and

experienced engineers with expertise in the field ofengine- and micro-electronic-technology.

One of the innovative NONOX-developed techno-

logies is the Electromagnetic Operated Control

Valve [EOCV] system, a system which substantial-

ly improves the efficiency of SI Natural Gas engi-

nes up to diesel like values.

The EOCV system was first applied and tested on

a single cylinder test bench where the concept pro-ved its validity. Following those results, a second

and third generation of the valve was developed

and finally applied to a 300 kW DEUTZ V6 engine.

The EOCV system replaces the throttle plate of a

conventional SI Natural Gas engine it avoids pum-

ping losses and it enables the application of signi-

ficant higher compression ratios.

A very important feature of the EOCV valve asused in the NONOX engine is that it operates com-

pletely electronically controlled without mechanical

drive from the engine. The EOCV valve uses its

own actuator which is controlled by its own valve

control system. This means that the operation of

the valve can be controlled independently. No

structural mechanical redesign of the original engi-

ne is necessary.

Of course the NONOX engine also has its own

engine management system in which total control

of all engine functions are co-ordinated. The valve

control electronics are interfaced with the overall

engine management system by means of a CAN

J1939 based interface.

The advantages of the NONOX engine:

- Fuel cost benefits compared to HDDE

- Same power as HDDE

- Specific fuel consumption within scatter of

0-5% compared to HDDE over entire map

- Reduction in CO2 emission of 25%

compared to HDDE

- Emission legislation level EURO 4 and

EURO5 / EEV

- Air-Fuel-ratio control

- Anti knock control

- Misfire detection control

The NONOX NG application

The NONOX NG engine has been developed usinga 1015 DEUTZ base engine.

The NONOX engine is a dedicated Natural Gas

Engine. A LPG version can be made available on

demand.

This NONOX/DEUTZ engine has been fully tested

and qualified and is now ready for series production.

Although the NONOX technology has been develo-

ped on a DEUTZ engine, the technology as such can

be applied as an add-on system to any series pro-

duction engine.
