The time period during which the vehicle runs on a predetermined amount of fuel, calculates the average value of the flow rate for a certain period of time, and transmits this result to the display. The disadvantages of the device are: the inability to determine the operating mode of the vehicle, the need to determine the amount of fuel each time for a certain distance.

For practical use in evaluating fuel-efficient driving, this device is complex and expensive.

A known device for evaluating fuel-efficient driving. It requires information on the actual fuel consumption of the car and the path traveled by it.

The disadvantage of this device is that it does not allow the driver to determine the zone of minimum fuel consumption.

device, and issuing recommendations to the driver on changing the operating mode.

A disadvantage of the device is its complexity and high cost, which makes it difficult to use it on production vehicles.

A device is also known that contains a sensor for engine speed, a metering position sensor, an indicator with a fixed scale, graduated in units of frequency, rotation, and two rotary indicators, one in the form of an arrow associated with a sensor for engine speed, in the form of a sector with a loaded loading scale connected to the position sensor of the metering body and made coaxially with the first pointer.

A disadvantage of the device is the mechanical connection between the sensor of the metering body and the index of the engine loading scale, which makes it difficult to manufacture and install the combined indicators on the car.

The aim of the invention is to increase the efficiency of use of automobiles and the reliability of the device by reducing the number of measured parameters while driving, simplifying the data processing process for evaluating efficient driving, facilitating installation, mounting the device on a car.

This goal is achieved by installing a measuring element on the vehicle, which includes a tuning position sensor for an all-mode regulator (HBP) made in the form of the same channels, each of which includes a mechanical obturator associated with a HBP lever, an optocoupler and an output signal shaper. The optocouplers are housed in a slotted housing located on the lid of the high pressure fuel pump. The output driver is made in the form of a flat sector with five slots shifted along the radii and mounted on the axis of the HBP lever.

..... In order to provide more accurate information about the position of the HBP lever, the obturator enters the slot, blocking or opening the light stream with the photocell (optocouplers) through the slots.

In order to reduce mechanical stresses and increase the service life, the measuring element is connected to the light signaling unit via electric wires through an converter including an encoder and a decoder.

To facilitate manufacture, installation and its readability, the light ring is made in the form of a ring placed along the outer diameter of the standard tachometer and having bulbs located equidistant to the tachometer scale. The light bulbs are electrically connected to the decoder.
