NCT Emission Test for a 10 year old landrover

I recently got a copy of this NCT emission test result and when I showed it to a few motor mechanics they were amazed that the emission test showed a result of 0.00/m in a 3 litre diesel powered Landrover with a turbo charger that had 127,000 miles on the clock. The pass threshold for the emission test on this type of car is 3.00/m This vehicle has been using Dipetane fuel treatment regularly. This is clear proof that Dipetane can significantly reduce  emission levels in cars and other motor vehicles. See the full NCT test result report below.    

Fuel Injector Problems – How to Diagnose Them and How to Fix Them

For many years, motor vehicles used a carburettor  to regulate the flow of air and fuel into the engine cylinder. From 1990 onwards stricter vehicle emissions requirements were introduced. This led to the introduction of catalytic converters which required a better method of controlling the air to fuel ratio in order to operate properly. Fuel Injectors  were then developed to replace carburettors. Understanding Fuel Injectors In order to achieve the correct mix of oxygen and fuel in the combustion chamber and enable catalytic converters to operate effectively, fuel injectors were developed to replace the carburetor in motor vehicles. Other machines such as lawnmowers, chainsaws and outboard motors still use a carburetor system. An individual fuel injector is used for each cylinder. Each fuel injector is essentially a pressure valve that monitors the flow of oxygen to the engine and dynamically controls the volume of fuel needed to maximizes combustion and minimize emissions from the combustion chamber. Why Fuel Injectors Cause Problems These can be caused by any one of the following issues: Clogged or dirty injectors: Symptoms of this include a loss of power, engine misfiring, alternating high and low engine revving Faulty injectors: Reasons could be a failure of an injector valve to open, to close or to leak fuel. This can result in a misfiring engine and a lower mileage performance.</span></li> Poor quality fuel: This will often lead to clogged injectors resulting in poor engine performance as outlined above. Other signs of poor diesel fuel quality include dark cloudy fuel or excessive smoke emissions. How To Avoid Fuel Injector Problems These problems can be very expensive on the pocket.

Solving Fuel Combustion Problems:

All hydrocarbon fuels have a fundamental problem of incomplete combustion. What happens is that oxygen in the vehicle combustion chamber is unable to completely burn the hydrocarbon chains. The result of this is the production of carbon (in the form of soot or ash) carbon monoxide, carbon dioxide, water and small amounts of several nitrogen oxides, commonly referred to as NOx. The gases and water (in the form of steam) are ejected through the exhaust but the unburnt carbon builds up in the combustion chamber to form a deposit. These deposits are called “Combustion Chamber Deposits” or CCD’s. These CCD’s are the main cause of wasted fuel, increased noxious emissions and fuel inefficiency. The result is increased fuel costs and greater engine and component part and wear and tear. Engine cylinder rings and engine oil must be replaced more frequently and the engine simply wears out before its time. Many additives have been developed to attempt to minimise this problem but they function by washing or removing the carbon deposits “after” combustion takes place. Dipetane is fundamentally different insofar as it interacts with the carbon “before” combustion occurs and enables the carbon to be burnt more completely. The result is more efficient combustion. This leads to reduced fuel usage and cost and a lower level of emission gases. The result is a saving in fuel costs and less atmospheric pollution for each vehicle using Dipetane.
