In some Lambert engines, normal operation can cause the diesel fuel in the engine and fuel tank to appear dark or black in color. Discoloration of the fuel can be caused by the following:
• Engine lubricating oil mixing with the fuel during operation
• The formation of asphaltenes
• Degradation of fuel from storage
Darkening of diesel fuel due to the mixing of lubricating oil or asphaltene formation does not indicate a manufacturing defect or other warrantable malfunction, and is a function of normal operation. Customers should continue using the equipment as is, unless the discoloration has resulted from fuel overheating, fuel contamination, or if fuel filter life is being reduced and causing operational difficulties with the equipment.

Mixing of engine lubricating oil: In some fuel systems, engine lubricating oil and diesel fuel are used in close proximity to each other for lubricating and sealing purposes. This interface is a function of fuel pump and/or in

Our repair products are designed to fit easily with your engine. Precision engineering is as firmly embedded in the Lambert fuel injectors, turbochargers and electrics as it is in the engines themselves.
Fuel injectors
Fuel injectors are critical to the way an engine works. They spray atomised fuel into the combustion chamber of the engine. They come as both mechanical and electronic items, according to the model of engine, and can be single or multi spray.
We undertake rigorous testing in developing our fuel injectors to bring them to the highest specification, so they can offer:
• Optimum combustion, combined with the highest level of performance, maximising the efficiency of your fuel
• Cleanliness
• Meet the latest emission standards, which vary according to where your operations are based
Fuel injection pumps
The fuel injection pump is among the most complex components in your engine. Its role is to inject the precise amount of diesel fuel at exactly the

When diesel engine working in normal condition, the engine sound will be smooth, rhythmic and coordinated. If the engine is running, accompanied by other sound, such as the intermittent or continuous metal percussion, continuous metal friction sound, etc., maybe the engine is not working properly, this noise is called diesel engine noise. Diesel engine noise is an important manifestation of engine failure, which is an important basis for judging and analyzing the fault. Once abnormal sound shows, it probably means the technical conditions of the engine body has changed. Diesel engine noise has a certain regularity, if we can master the abnormal sound characteristics of the diesel engine, it will be of great help for the diesel engine troubleshooting .
