Why to buy the PPG meter?

 

I’ll describe you the basic information that could help you to decide about the PPG meter purchase.

So, why buy the PPG meter:

  • because you’ll make me happy....which is actually not important for you
  • to have an overall view of the technical state of your paramotor in order to enjoy a safe, calm and long flight

A little bit of history – we have started to produce our PPG meter with the foundation of the company called Flyengines. The reason was pretty clear – to measure all the necessary parameters in order to check what is happening with motors used in different regimes that are characteristics of paragliding.

  • maximum engine power
  • maximum service life
  • fine motor operation in a medium speed – the flight in a horizon
  • minimum consumption

We could say that these parameters are mutually exclusive. The maximum engine output can be reached at the expense of the service life. And the maximum service life can be reached at the expense of the maximum engine output.  The fine motor operation in a medium speed in the horizontal flight with the minimal consumption (that is given by the setting of the working of the motor with the weak mixture) is in opposition to the maximum service life and the engine power.

How to get out of this? Simply – Golden Czech hands

There is a wide range of motors for paragliding on the market. Unfortunately the most of them is standing under the principle of the maximum service life. This state of the motor can be easily recognized by the temperatures in which the motors are moving - these are:

- the temperature of the head of cylinder - CHT

- the temperature of exhaust gases - EGT

The standard motors are moving around the temperature until 150 degrees of the cylinder head of the motor (passing away the wrong engine cooling and the influence of the surrounding temperature) and the temperature around 550 degrees of exhaust gases (in this case there is no influence of the ambient temperature).

The temperature of more efficient motors is ranging from 200 degrees to 600-650 degrees. Just to mention, the temperature of the racing motor can reach 850 degrees, but it has to agree with the engine operation (the unstable run in the same rotation speed).

Just this stable engine operation (the same rotation speed for the long term in the regime of the weak mixture) is a very hard burden to carry for the motor.

To make a long story short, enough theory, the Flyengine motors grappled with the problem and you can see the result on the web.

The measuring of the temperature of the exhaust gases serves to signal you the state of your motor. How?  Simply, any changes of the induced blend and of the engine power can be realized on the temperature of the exhaust gases, immediately.

In warm conditions the temperature of the cylinder head will identify the hazing of the motor, so you can decelerate it.

 

Example:

You have been using your paramotor with the PPG meter for a quite a long term and you know exactly the movement of the exhaust gases temperature. You know both the temperatures in the stable regime and the temperatures in the maximum power. These temperatures are quite appropriate but suddenly you realize their growth.

You do not have to remember the number because there is a possibility to set up an alarm for the temperature monitoring so that the limit of the closure is a little bit higher than is your standard value of the satisfied flight.

Often happens that you take some wrong fuel or dirty petrol which have an influence on the ration of the bland of motor. Bad the fuel hose or fuel-line leak also.

The view of the fuel gauge is the information you need for your long and calm flight and for the early return from trip.

I’ve just tried to provide you with some useful information to get prepared for a new season because this one-2014 will be awesome!!!
