3.4 Air Intake System
If the gas engine is without the air filter, operator should fit the air filters and filter status
indicator. The air intake system must avoid the followed material entry into it:

Water or rain.

Dust.

Exhaust gas.
The air filter should be kept an enough distance from the heat resource.
The allowed temperature increasing before the turbocharger compressor inlet is 5
℃
.
The filter should be matched with indicator to monitor its resistance status.
The initial resistance of the new filter should be
≤
3 kPa. The resistance of the dirty filter
should be
≤
5 kPa.
The filtration efficiency should be
≥
99.7% during the filter life.
The minimum diameter of the filter outlet pipe should be
≥
160mm.
3.5 Exhaust System
The exhaust system must meet the following requirements:

Exhaust back pressure must not exceed 7.5kPa.

Exhaust system components should not exert excessive stress on the exhaust manifold
or turbocharger. The exhaust system parts' weight, inertia, relative movement between
components, and dimensional change due to thermal load can exert excessive stress.

Avoid the exhaust pipe having sharp turns. The bend radius of the pipe should be big as
much as possible and sharp corner is not allowed.

When the exhaust pipe is close to the intake pipe, rubber parts, plastic parts, fuel tanks,
etc., an insulation board must be added in the middle and the distance should be in-
creased as much as possible.

The inner diameter of the exhaust pipe should be
≥
220mm.

The exhaust system must be able to prevent rain, snow or splashed water from entering
the engine.

The exhaust gas must be ventilated to ensure engine performance and the operator's
health.

Permitted max bending moment at the turbocharger flange is 10N·m.

The highest exhaust gas temperature after the turbocharger is 680
℃
.
3.6 Cooling System
In order to ensure excellent engine life and cooling performance, the installation of the radiator
must meet the following criteria:

When installing the radiator, install the vibration absorber.
