How to Choose Fuel, Lubrication Oil and Coolant of Yuchai Diesel Engine

Don't know how to select engine fuel, lubrication oil and coolant? Don't worry, this post will guide you to select the right one.
① Fuel
The fuel should be selected according to ambient temperature. The selection should comply with light Diesel Fuel(GB252 choice fuel and first class fuel).
Ambient temperature


② Oil
Lubricating oil should be selected according to the ambient condition. The class of oil should not be lower than CD class of GB11122–1997
Ambient temperature




③ Coolant
The coolant should be anti-freezing, especially when the engine is used in the plateau and in cold weather(below 0℃). It is good for the engine. The most used anti-freezer is glycol-water, which is a mixture of glycol and water( soft water is best. such as well water, spring water or other hard water, it should be mixed 2g tri-sodium phosphate with one liter water for softing). Selection of different proportionality coolant should vary with the ambient temperature.




Note:
When the percentage of the glycol is above 68%, its freezing point rises. So the percentage of the glycol should not be above 68% when you make up anti-freezer. Glycol is a transparent, viscid, poisonous liquid. Wash your skin with water immediately if it contacts your skin. Glycol is flammable. So, do not weld or light fire when there is coolant leakage.
When there is an emergency, anti-freeze can be replaced by soft water, such as tap water and rain water. Otherwise there will be scale on the wall of water jackets of diesel engine and the deposit will weaken cooling effect and cause the engine to over heat.

What Is the Difference Between Electric Motor and Electric Generator

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and winding currents to generate force. In certain applications, such as in regenerative braking with traction motors, electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction. An electric generator operates in the reverse direction, converting mechanical energy into electrical energy. Electric generator can be divided into various type, open type, silent type, trailer type, portable type and container type, etc. Electric generator is mainly composed of diesel engine & alternator. Electric generator set is mainly composed of engine, alternator, control module, and common base. Electric generator :- Electric generator is a type of machine which converts mechanical input (energy) into electrical output (...
