The diesel engine should be overhauled when

First, the power dropped significantly. When the throttle is in the maximum position, the maximum output power of the diesel engine is only about 60% of the rated power, obviously with no configuration load. For fuel, air distribution, crankshaft linkage, and other related parts, the power cannot be restored after maintenance adjustments.
Second, fuel consumption has increased significantly. When the fuel consumption exceeds the rated value of 30% - 50%, the oil consumption of the oil exceeds the rated value by more than 1 time. The exhaust gas brings out the oil, and the crankcase ventilation port (or fuel filler port) takes the smoke with oil mist inside the crankcase. The temperature increases significantly.
Third, cylinder liners, pistons and other parts wear seriously. The wear of cylinder journal piston and crankshaft exceeds the limit value, and the parts and components of the air distribution mechanism wear badly, which makes the sealing performance of cylinder liner worse and the cylinder pressure decrease.
Fourth, can not start smoothly. After shutting down, when the cooling water temperature is 50-60°C, it can not start smoothly and the working temperature of the diesel engine is 70-90°C. The cylinder also emits sound from the piston and piston pin, main bearing or connecting rod bearing.

The human tongue has a range of specific taste sensation neural receptors called taste receptors which are organized mainly as papillae on the tongue.  When stimulated by chemicals, natural or synthetic, organic or inorganic, cations or anions, the receptors send signals to the brain which interprets the stimulations as sweet, bitter, sour, salty, and savory (unami, meaty taste).   For examples, cations such as Na+ present in the table salt evoke the salty taste, and H+ presents in acids evokes a sour taste. Organic compounds such as sugars, dextrins and glycerol result in sweet taste, glutamate results in  savory taste, while many toxic compounds such as nicotine, morphine, caffeine, quinine, etc. result in bitter taste.  The sensation of tastes is an evolution trait for defense against poisons (normally evoke bitter taste), and for allowance of nutrients intake (normally evoke sweet or savory taste).  


Sugar is a natural sweetener as well as a nutrient consumed in vast quantity around the world.  It is one of the major calorie intakes by humans.  Over consumption of sugar often leads to obesity and other related medical conditions.  High blood sugar level (hyperglycemia) is a manifestation of the disease diabetic mellitus; if not managed properly, it could lead to a range of medical complications. To combat these medical conditions, high potency Sweeteners with no calorie or low calorie intake are often being used to substitute sugar.  Proper control of calorie intake, coupled with the use of these sugar substitutes has been very effective in managing the medical conditions.   


Besides the medical indications, using sugar substitutes brings the economic benefit of lowering the cost of many foods and consumer products, from soft drinks to cakes, pasties, and even toothpastes.  


A variety of chemical compounds, natural or synthetic, can evoke sweet taste, but not all of them are safe (for example lead acetate has a sweet taste but it is extremely toxic), nor are sweet taste specific (for examples, many of synthetic sweeteners can also evoke other senses of taste such as bitterness or metallic sensation).  Therefore, selection of the right sweetener for a specific use depends not only on the cost, but also more importantly on the health and safety, the sweetening potency, the effectiveness under various physical conditions such as cooking temperature (heat stability) and pH, as well as other unwanted tense of tastes of the sweetener.
