O&M Manual for PowerKit
M26 Series Diesel Engine


If the PowerKit is installed in a soundproof box, seal rubber is installed around the radiator
to prevent the hot air in the engine compartment from flowing back into the air intake
channel.

Radiator grounding measures must be taken to eliminate potential differences and pre-
vent electrical corrosion (aluminum radiators do not require this).

The direct windward surface of the radiator should not be blocked, and the direct wind
area should be greater than or equal to 80% of the radiator's positive area.
3.7 Lubrication System
Users must follow the requirements in 6.2 Lubricant recommendation.
3.8 Fuel System
The installation of the fuel system must comply with the following requirements:

When the engine is stopped, the fuel system does not allow the fuel to flow into the en-
gine through the fuel inlet pipe or the injector return line due to gravity.

The injection resistance of the fuel injection pump shall not exceed the specified value
with a clean fuel filter. The resistance is based on the half-full fuel tank.

The return oil must not generate pressure fluctuations in the pipeline.

The fuel tank must have a vent and fuel return connection to allow air and other gases to
properly separate from the fuel without pressure in the fuel tank. The vent must also pre-
vent the entry of dirt and water.

The temperature of the fuel entering the engine must be lower than the specified value in
the engine data sheet.
3.8.1 Fuel Tank

The lowest position of the fuel tank shall be no less than 1m(3.3ft) from the fuel pump of
the engine, and the location shall be far away from the heat source. The fuel tank shall
have proper space and ventilation;

The device should be set up to periodically drain the condensed water in the fuel tank and
the filter, and signs should be placed to remind the user of such;

The fuel tank has ventilation function to prevent the pressure inside the tank from being
too high and the vent hole should be dustproof and waterproof;

The fuel tank must have 5% liquid thermal expansion space to prevent the fuel from
overflowing after it expands.
3.8.2 Fuel line

The fuel line shall comply with the requirements of the fuel line matching specification.
