We are all accustomed to standard forms of measurement, be it kilometers per hour or amperes per hour. But pilots of small-caliber vehicles are concerned about completely different indicators – motor hours. I think not everyone knows what it is.
– Oh, okay, how many hours the motorcycle has worked for you and how many hours! – someone will say.
I admit, there was such an opinion and I had, they say, how many minutes the engine rumbled, divided by 60 and got the number of hours – wow. But no. It is clear that the newer the model of equipment, the more likely it is that the sensor is installed, which ticks and counts the hours. However, this does not in any way prevent amateurs from looking for comparisons and equivalents, they say engine hours are how many kilometers or how many liters of gasoline consumed, how many times do you need to rush to the nearest village for salt to end the engine hours?
Let’s start with a simple one, it is useless to determine the hours in kilometers, because measuring in the usual units of kilometers or miles is a banal mileage. Hence the first discovery, mileage and engine hours are completely different indicators. I will say more, not only motorcycle engines are tied to engine hours, but also many other small-scale household units. But what about a technique that moves a little, which wears out its resource, and adds mileage from a gulkin’s nose? How are you going to measure in kilometers the service life of, for example, a welder or a compressor? Is it like how many hours we roll them around the garage, how many hours will it pass? Moreover, measuring the engine life over the distance traveled is a completely one-sided approach, even if I drive all the time in search of happiness, who said that the engine always runs at the same speed?
Hours are tied to the ratio of time and power. The engine hour runs through an hour of operation of the engine at its maximum capabilities, since wear in this case will be most noticeable. And if you do not force the engine, you have enough moderate speed, then the engine hour will pass for a longer period of time.
Once again, the engine hour is the rate of wear per hour of operation at the upper limit of the output power, if you want – the number of engine revolutions and rotational speed, the higher they are, the sooner the engine hour comes to an end. With quiet operation, the resource is also wasted, but not so quickly, therefore, to the desired ratio in one motor hour, you can drive longer at lower speeds than at increased ones. Hence such a frequent hassle with consumables on motocross motorcycles.
With the amount of fuel consumed, in theory it can be calculated very, very relatively. Because the more aggressive the driving, the greater the gas mileage, and this can be remotely related to engine hours for a couple of tens of light years.
What is this for?
Everything is trite. The resource is being developed, which means you need to mentally prepare for the replacement of consumables. The more hours are measured, the closer is day X, when you will have to do the inevitable MOT, change oils and much more. This is a very logical approach, because it is the nature of the operation of our motorcycle that will show how soon you will have to run to the store and fork out for new oils and consumables. After carrying out all the necessary work, the clock is updated and can be counted again.
For each engine, these indicators are individual, in the manuals for the use of equipment, it is necessary to indicate after how many hours of operation it is necessary to make replacements.
