A motorist who has installed gas-balloon equipment on his car will constantly learn from various sources, features, details about the proper operation of such equipment.
Gas-powered cars are certainly more environmentally friendly than their gasoline and diesel relatives. In addition, cars with HBO in the operation of its owner cost much cheaper. So what they are, these engines that run on gas?
The first group of equipment equipped with gas-balloon equipment can be attributed to conventional gasoline engines. These engines can operate on both gasoline and
and gas. And among the engines equipped with HBO make up most of it.
The second group includes diesel engines, upgraded to the so-called "gas-diesel cycle." In the cylinders of this type of engine is not just served
clean air, and gas-air mixture. At the end of the compression stroke, as in a conventional diesel engine, fuel is injected, which ignites and ignites this gas-air mixture. It should be noted that with this design of the engine diesel fuel will require quite a significant amount.
The following group may include diesel power units converted to spark ignition. An air-gas mixture ignited by the spark plugs is fed into their cylinders. Diesel engines of the previous and this group are equipped with city buses and long-haul trucks.
The last fourth group includes engines specially designed to operate on gas fuel. In this family one can meet both transport and stationary motors, with the latter being the majority.
The most common are two types of automotive gas fuel:
- compressed natural gas (methane) or CNG (compressed natural gas) or CNG (Compressed Natural Gas);
- liquefied petroleum gas (propane-butane) or LPG (liquefied petroleum gas) or LPG (Liquified Petroleum Gas);
Depending on the installed equipment, the engines of the first group are operated on methane or propane-butane.
Engines of all other groups are exclusively on methane.
What is the effect of gas on the properties of motor oil?
Let's start with a positive impact.
- When the engine is started, the oil film from the walls of the cylinders is not washed off, there is no oil dilution with fuel, as a result, the aging of the oil slows down;
- Thermal load on the oil film on the walls of the cylinders when working on gasoline is higher than on gas and again, as a consequence, a slower aging of the oil.
There are results of studies confirming that when operating on gas, the service life of engine oil for passenger car engines can be increased by 80–100%. But this does not mean that the oil can be changed twice less. It is necessary to be guided first of all by the recommendations of the plant - a manufacturer of equipment. But it is safe to say that when the engine is running on gas, the oil loses its quality side much more slowly.
We give a few negative features of the influence of gas fuel.
Compared to conventional motor fuels, more gas and nitrogen oxides are formed when gas is burned. In this regard, the oil for the engine operating on gas fuel must be resistant to watering and the effects of nitrogen oxides (nitration). In addition, engine oils for gas engines should contain a limited amount of organometallic additives, have a lower sulphate ash content, as compared with conventional oils. This is necessary in order to prevent the formation of
on valves, piston heads, spray nozzles and in high-temperature deposits of combustion chambers that adversely affect the operation of the engine.
But this is not all the troubles that threaten moisture. Some base oils (eg esters) start to decompose when exposed to water. The same can happen with some oil additives. Therefore, if a synthetic oil is chosen for a gas engine, it is necessary that it does not contain esters.
In the TM TEMOL product range, there are LUXE series universal oils, namely TEMOL LUXE 5W-30 and TEMOL LUXE 5W-40 oils with high oxidative stability and low sulphate ash content, which allows them to be used in gas-powered automobile engines, as well and TEMOL GAS 10W-40 oil, in the production of which special additive packages were used, which increase resistance to negative factors arising from the operation of an automobile engine on gas.
TEMOL GAS 10W-40 is a semi-synthetic all-season motor oil intended for lubrication of engines of automotive vehicles running on compressed natural gas (CNG) and liquefied petroleum gas (LPG). Suitable for use in cars and small trucks, buses. It has high antifriction properties. It guarantees a high level of protection against oxidation and nitration of oil. It prevents the formation of deposits.
The considered positive and negative aspects affecting the required properties of motor oils for gas-fueled engines are themselves regulating factors in choosing the right lubricant. These factors significantly affect the required properties of the engine oil and its further impact on engine parts. Therefore, it is so important the right choice of engine oil for gas vehicles.
