How to Deal with a Caterpillar Engine That Won't Start in Cold Temperatures

When the weather is getting colder, large vehicles that are stored in uninsulated sites will face problems that make them difficult to start, and the same goes for the Caterpillar Engine. Maybe you are experiencing the same problem, don't worry, it is very common, this article will help you to solve the problem effectively.

When the outdoor temperature is around 0°C, the difficulty in starting the caterpillar engine may be due to the following reasons:

1. Insufficient actuation pressure of the hydraulic pump. Oil and lubricating oil will lead to hydraulic pump power problems, in simple terms, when the hydraulic pump of the caterpillar engine is not enough oil in the hydraulic pump, often resulting in clogged lines, there is not enough oil to pressurize the engine lubricating oil is equally important, in the use of the excavator, it is easy to generate sludge, varnish and other deposits, oil such as not being replaced in a timely manner, the deposits entrained in the The micro-metal particles in the sediment exacerbate the wear and tear between the hydraulic pump plunger and cylinder, and in severe cases, the pressure regulator valve is jammed. All of these will result in insufficient actuation pressure, so in the use of caterpillar engine, must be regularly checked and replace the oil, oil replacement time needs to be reasonably adjusted according to the actual working conditions, for example, the work intensity of the machinery needs to replace the oil more frequently, the work intensity of the small machinery is the opposite.

2. Using the wrong kind of oil. There are many types of motor oil oil, the difference between the various oils is also very large, poor quality oil may also cause the engine in the low temperature environment can not start. Therefore, you need to be very careful when choosing and buying, you need to follow these principles:

(1) Selection according to engine type. Engine oil is also depending on the different types of engines into two kinds, one is called gasoline engine oil, another is called diesel engine oil, the two can not be mixed; (2) according to the provisions of the use of automobile selection. Should be based on the working conditions of the automobile engine, choose the appropriate oil varieties and use level. (3) According to the use of automobile environment selection. In the low temperature selection of drilling too much when it is easy to cause the oil solidification, the engine in the starting oil mobility is poor, easy to cause the dry friction of the axle tile, resulting in burning tile, holding the shaft and so on.

In addition, some machinery using battery ignition, winter, battery electrolyte viscosity increases, mobility and diffusivity deterioration, so that the chemical reaction can not be fully carried out, resulting in insufficient power, affecting the start.

For the above reasons, there are several solutions:

For oil, the general principle is to find a way to increase the supply of oil at startup to make up for the lack of oil due to low temperature and poor volatility of gasoline; for lubricant, in order to reduce startup resistance, you can change some lubricants with low viscosity in winter;

As for the current, if the power is insufficient, it should be charged in time to ensure that it has sufficient power. In addition, the electrode gap of the spark plug can be reduced.

3. Failure of caterpillar engine parts

If you are sure that the above points do not exist, then there is still a possibility that your caterpillar engine parts have malfunctioned. When the caterpillar engine parts fail, you need to replace the parts in time.
