Energy from <strong>Gas</strong><br />
<strong>Gas</strong> is clean<br />
Low emissions and high efficiency in<br />
energy production play a key role in<br />
investment decisions.<br />
As emission requirements and regula-<br />
tions become more and more stringent,<br />
gas offers many advantages:<br />
>> low CO 2 emissions<br />
>> low NO X emissions<br />
>> minimal SO X emissions<br />
and<br />
>> no particle emissions.<br />
<strong>Gas</strong> is efficient<br />
Producing energy with gas is highly ef-<br />
ficient. The operation and maintenance<br />
costs of a gas power plant are lower<br />
than those burning other fossil fuels.<br />
<strong>Gas</strong> is flexible<br />
No matter what your requirements are:<br />
production of electricity, combined heat<br />
and power or Tri-Generation. <strong>MAN</strong><br />
B&W gas engines reliably supply you<br />
with cost-effective energy.<br />

<strong>PGI</strong> – <strong>Otto</strong> engine<br />
<strong>without</strong> spark plugs<br />
“Performance <strong>Gas</strong> Injection” – or just<br />
“<strong>PGI</strong>”. Behind this abbreviation is<br />
hidden a new, revolutionary gas engine<br />
concept which makes spark plugs<br />
completely unnecessary. With its <strong>PGI</strong><br />
engine, <strong>MAN</strong> B&W Diesel succeeded to<br />
develop an <strong>Otto</strong> engine with the effec-<br />
tive mean pressure of a state-of-the-art<br />
Diesel engine.<br />

The innovative<br />
<strong>PGI</strong> principle<br />
The patented <strong>PGI</strong> concept is based on<br />
the ignition, at a hot spot of a small<br />
amount of pilot gas, injected under high<br />
pressure, in a pre-chamber.<br />
This will lead to the ignition of the gas/<br />
air mixture in the main combustion<br />
chamber of the lean-burn gas engine.<br />

Basic principle of technologies<br />
No more replacements<br />
of spark plugs<br />
As our <strong>PGI</strong> engine no longer has spark<br />
plugs, you will not have to invest any<br />
time in replacing these.<br />
By using only reliable and approved<br />
industrial components for the <strong>PGI</strong><br />
ignition system, we insure long periods<br />
between overhauls (TBO).<br />
Clean combustion<br />
With its NO X -emissions<br />
(< 250 mg/nm 3 ) our <strong>PGI</strong> gas<br />
engine undercuts the “TA Luft”<br />
specifications by 50%.

Applications<br />
It does not matter which kind of energy you require or in which form. Power plants<br />
with <strong>MAN</strong> B&W <strong>PGI</strong> gas engines guarantee highest efficiency at lowest emission.<br />
This is of advantage for your business and good for the environment.<br />
Urban<br />
In densely populated urban agglomera-<br />
tions, the requirements concerning<br />
space, emissions and noise protection<br />
for a power plant are restrictive.<br />
To further increase the efficiency, more<br />
combined heat and power plants (CHP)<br />
are being built every year.<br />
Industrial<br />
Industrial areas normally have less<br />
restrictions concerning space and noise<br />
protection. Depending on the applica-<br />
tion, heat from the production process<br />
of electricity can be used in many diffe-<br />
rent ways.
Remote<br />
Power plants in remote areas do not<br />
normally have to cope with space-<br />
limiting restrictions. The environmental<br />
requirements in these areas fulfill the<br />
Worldbank environmental specificati-<br />
ons.<br />

Modular Design<br />
Flexible<br />
<strong>MAN</strong> B&W gas power plants are built in<br />
a modular manner. This offers you maxi-<br />
mum flexibility, whatever you require:<br />
urban, industrial or remote zone design –<br />
or for the future extension of your plant.<br />
Fast<br />
Modular construction means that only<br />
standardised and well-proven modules<br />
will be utilised in the construction of<br />
your power plant.<br />
This helps to save time in project plan-<br />
ning and construction <strong>without</strong> losing<br />
quality and reliability.<br />

Efficient<br />
Standardised modules, our competence<br />
and experience lower the costs of pro-<br />
ject planning, assembly, operation and<br />
maintenance due to consistent and<br />
integrated planning from one source.<br />

Operation and Maintenance<br />
Today <strong>MAN</strong> B&W Diesel , s 32/40<strong>PGI</strong> gas engines meet tomorrow , s expectations and<br />
requirements for operation and maintenance.<br />
The engines grant high flexibility to the operator and make long maintenance-free<br />
operating periods possible.<br />
Low costs<br />
>> No spark plugs mean no more<br />
time is spent on spark plug<br />
replacement.<br />
>> All engine components have long<br />
periods between overhauls (TBO)<br />
as gas burns cleanly.<br />
>> High efficiency with low<br />
emissions.<br />
Ease of maintenance<br />
>> All engine parts are designed to<br />
grant easy and quick access.<br />
>> Spacious openings to the<br />
camshaft and crankcase.
