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 (

Engine Fault Code Messages - Volvo Penta Engine

Volvo Penta Engine Fault Code When a malfunction has occurred and the diagnostic system has generated one or more fault codes, these are read out differently depending on the equipment used. Please refer to “Fault code messages”. If the system indicates that a fault code has been set: 1 Cut engine speed to idle, or shut the Volvo engine off. 2 For DCU/DU Read the fault code from the display, please refer to Reading fault codes via the DCU or Reading fault codes via the DU. For CIU press the diagnostic button and read the fault code, by observing the flashing of the diagnostic lamp. Refer to Reading fault codes via the diagnostic lamp, CIU. 3 Look up the fault code in the Fault Code Register chapter and take the recommended measures. Reading fault codes via the DU (Display Unit) Depending on the severity of the fault the text, either WARNING! or ALARM STOP (a buzzer sounds) will be shown on the display 1 Press any button to come to the fault list. The f

Types of Diesel Engine and Application of Diesel Generator

This article will guide you to learn diesel engine types and important role of diesel generator. If you are interested, please keep reading. What Are Diesel Engines? A type of internal combustion engine more accurately known as a compression ignition engine is designed to provide power by compressing the fuel at high temperature and significant pressure until it ignites. Diesel engines are either two-stroke or four-stroke . ‘Stroke’ means the movement of the piston in the engine. Two-stroke This engine uses one stroke in each direction. The first stroke being compression, which results in the ignition of the compressed fuel. The return stroke brings new fuel into the cylinder. Four-stroke This engine has one compression stroke and one exhaust stroke and each one of those has a return stroke – hence, four-stroke. The compression stroke compresses the fuel/air mixture prior to ignition. The exhaust stroke pushes the burnt gases out the exhaust. The
