Diesel engine basic operating principle
The diesel engine is a compression - ignition (CI))engine operating on
the principle of air inducted through the intake valve sucked in to the engine combustion chambers by
downward movement of the piston then being compressed on the upward stroke of the piston.
The air temperature increases to around 800 degrees centigrade as it is compressed.
Diesel engine basic maintenance
For the diesel engine to operate efficiently it is essential that the
fuel injection equipment is maintained in good order.
We can supply a range of diesel fuel line equipment including filtration, hose, sealing washers, delivery equipment, fuel injectors, fuel pumps and test equipment etc.
Diesel fuel injection pumps operate at very fine tolerances and
require accurate calibration with highly specialised equipment.
There are many types of diesel pump from different manufacturers
ranging from single cylinder fuel pumps to large multicylinder pumps.
To identify a fuel pump for repair replacement or service part numbers are almost always required.
Computerised diesel engine diagnostics
Automobile diesel engine technology has progressed away from the association with sluggish performance, noise and fume pollution, towards quiet running, fuel efficient ,low emission , high torque performance engines with sophisticated electronic control.
Modern diesel engines relay on complex electronic control systems.
We can supply & fit:
The diesel fuel injectors are a key component in delivering fuel into the combustion chambers
of the engine and require periodic servicing / calibration to prevent problems with misfire,
excessive smoke, uneven running, etc.
Diesel injectors operate at high working fuel pressure and can suffer
from wear and carbon fouling which may result in fuel leakage , wrong opening pressure & incorrect spray pattern
To achieve low carbon particle exhaust emissions and maximised performance diesel engine design must include increased fuel injection pressures and precise control of the timing of the fuel injection in the engine operating cycle.
Further enhancements include purification of exhaust gases by special filtration (diesel particulate filters) and chemical fuel additive treatment in the exhaust system to allow vehicles to meet strict european emission legislation.
