REVIEW OF COMPLIANCE WITH EUROPEAN MACHINERY
SAFETY REGULATIONS AND "CE" MARK

4.5.3. FORCED INDUCTION
In the supercharging circuit (downstream of the turbocharger), the components are sealed is mechanically with
Viton O-rings. Rubber sleeves and other materials have been totally discarded.
4.5.4. MANIFOLDS AND EXHAUST PIPE
To limit leak risks, the engine exhaust manifolds are mechanically sealed with special metal-reinforced joints.
For the purposes of protecting the operators from accidental contact, we have designed a cooled exhaust
manifold with the engine cooling water circulating outside and around it so that the temperature on the exhaust
manifold surface, otherwise 400 to 500 ºC, falls to the coolant temperature levels of 80 to 90 ºC.
As for the turbocharger, the turbine casing (exhaust side) is also very hot and cannot be cooled but is protected
with a heat-insulating blanket (or jacket) limiting the surface temperature to less than 90 ºC. This solution also
applies where the engine application requires the use of hot (uncooled) exhaust manifolds.
A similar type of protection covers that part of the exhaust elbow or pipe extending to the connecting flange on
the hose for connection to the external exhaust pipe. The installation project must protect this exhaust pipe.
When supplying the installation, we check for any contact with this piping and, where appropriate or for exhaust
heat recovery if desired, we protect the pipe with a stainless steel lined heat-insulating blanket.
4.6. VIBRATION
Engine vibrations do not affect operator safety, although they could be transmitted through the engine mounting
to other machines or to the building, causing a nuisance for people in the neighbourhood. Engines for
applications where structure-borne vibrations are likely to occur will be isolated from their support by elastic
vibration absorbers.
We also use flexible elements to connect all the utilities (water, fuel, oil, etc) to the outside of the engine.
4.7. NOISE
Noise generation is inherent to the engine and is generally inevitable although design approval is conditioned to
a sustainable sound level when adequate and necessary means of protection are used.
Ear protection is necessary for all the people present in the engine room when the engines are running.
Therefore, at the entrance to the engine room, there must be a clear and visible warning of the obligation for the
operators to wear ear protection.
No type of ear protection is specified, as the certified personal protective equipment usually available on the
market is considered suitable.
As regards noise outside the engine room (environmental noise pollution), it is necessary to install - and we do
install in all cases - adequate exhaust silencers to meet the local or environmental rules and regulations in force
where the engines operate.
4.8. ELECTRICAL INSTALLATION
The engine’s electrical installation consists of one terminal box for the connection of 24 V DC and 220 V, 400 V,
480 V, etc, devices, including sensors, contacts, etc. This terminal box and the wiring for these devices comply
with the low voltage wiring regulations and Directive 73/23/EEC as amended by Directive 93/68/EEC. There is a
switch on the front of this box for immediately stopping the engine in an emergency.
