. Those who handle fleets, they have to know the common fuel consumption of vehicles within their fleet. Of program, the average fuel consumption is not always the same in all scenarios and at times it is necessary to examine vehicles with respect to diesel testers. Also, we test vehicles to be able to prevent or discover fuel exploitation.

In essence, this test consists of three periods:

1. supply of fuel only prior to the start of vehicle operation, 2. vehicle operation and 3. supply of fuel by the end of the automobile operation.

The first thing to look for when testing is a place, that is, the area, on which the car is on, through the diesel testers supply. For a check to be legitimate, the surface should be, straight and level, without any incline or, when the surface isn't horizontal, to the both fuel supply, the gradient has to function as the same. In both gas supply, fuel tank should be filled to the exact same degree. The greatest, and easiest to run it, will be to fill a reservoir to the brim. When pouring the gas in the tank, froth creates. When the fuel level in the reservoir reaches the top, we must wait for foam to remove and, if required (and mostly it is), pour more gas in the tank so that it's full.

When the automobile is correctly supplied with fuel, we must gather the next information:

1. the absolute distance traveled in car kilometers (mpg), 2. total time in hours of vehicle operation, 3. If you have a fuel monitoring device, we must record and data on the entire amount of fuel consumed in liters.

When the vehicle is correctly supplied with gas and when we recorded all needed info, the vehicle can head to work. During process of the vehicle, it needs to be said that the scale that signals the engine speed remains in the green box, that is, should not be in debt carton. It's also wise to pay interest to the sound of the engine. Upon finishing the vehicle perform, we must furnish vehicle using a fuel and record information in the same way. Nonetheless, at about 50 vehicles, as there are in our fleet, which participate in distinct producers, on n-one of the automobiles the device will not show the exact fuel consumption. In evaluations, we get deviations higher than 10%. Additionally, these deviations aren't steady, but the two evaluations vary considerably for one and the sam-e vehicle. These tests are done, by ourselves, and underneath the superintendence of official reps of car manufacturing companies.

As for us, such car manufacturers answers are not satisfactory, we hunted on.

A device that has helped us to figure out the difficulty of abuse of gas on vehicles, was “EDM eco”, produced by VDO.

This device connects with vehicle electronic equipment and supplies, inter alia, the following advice:

1. fuel consumption at every minute while vehicle is proceeding and while vehicle standing, in litres/100km, litres/hour,

2. average fuel consumption because the vehicle is generated, in litres/100km, litres/hour,

3. total consumed quantity of fuel since the automobile is created in litres. Precision of data supplied by EDM eco was 3per cent plus and minus, which was supported by the tests which was satisfactory with the standpoint of the owner of the vehicle fleet.

These devices are positioned at about 50 vehicles in our fleet, and are used about 6 years. During operation, the apparatuses were accurate and reliable. Differences outside the limits prescribed by the manufacturer isn't occurred except in the case of fuel exploitation Discover More.
