6 Steps for Special Vehicle Engine Maintenance

- Dec 16, 2019-

The engine is the heart of a special car, and maintenance is essential if you want to save money. Learn how to maintain, the "6 steps" of diesel engines is indispensable!

 

Break in first

Why do you have to buy a special vehicle for the first insurance, how many kilometers will be driven after the first insurance? That's because running-in is the basis for extending the service life. Whether it is a new car or an overhauled engine, it must be run-in according to regulations before it can be put into normal operation. If the running-in is done well, the special-purpose vehicle lacks power, high fuel consumption, and early wear and other problems can be effectively avoided, maintaining the vehicle's power and economy. During the running-in period, pay attention to gentle use to avoid excessive speed and excessive engine load.

"Four Nets" Guarantee

Diesel special vehicles account for a large proportion of other fuel vehicles, and diesel is the main fuel of the engine. If the diesel is not pure, it will cause wear and tear of the precise matching body and increase the clearance, which will cause oil leakage, dripping, and oil supply. The pressure decreases, the clearance becomes larger, and even the oil circuit is blocked, and the shaft burnt and other faults are caused. Therefore, we still have to comprehensively measure and use higher quality oil products. In addition to oil, water, gas and airframe can also effectively protect the engine. For example, if the cooling water is pure, it will reduce the probability of cooling system scale blocking, and make the engine heat dissipation easier.

 

Oil foot water foot air foot

To ensure that the diesel and air supply of the special-purpose vehicle are timely and uninterrupted, the special-purpose vehicle can avoid problems such as difficult starting, poor combustion, reduced power, and poor engine operation. Sufficient oil supply can make the engine more lubricated and reduce body wear. Sufficient cooling water can make the engine cool better and prolong their service life.

 

Tightness check

Due to the impact of vibration and uneven load during the use of the diesel engine of the special vehicle, bolts and nuts must be checked for some tightening. It is also necessary to re-tighten the various connecting parts on the vehicle after the break-in period ends to restore the pre-tightening force. For example, clamps on engine accessories, connectors on drive shafts, bolts on tires, frame bolts, and so on.

 

Check adjustment

The places that need to be checked and adjusted can not be ignored! The valve clearance, gas distribution phase, fuel supply advance angle, fuel injection pressure, and ignition timing of the diesel engine of the special vehicle should be checked and adjusted in time to ensure that the engine is always in a good technical condition to save fuel and extend service life .

 

Standard use

Before the special vehicle runs, the lubricating parts such as the bearing pads should be lubricated. After starting, it should be put into operation when the water temperature reaches 40 ℃ -50 ℃, it is best to avoid long-term overload or low-speed operation. Before stopping, unload the load and reduce the speed. The engine maintenance work must be done regularly to keep the machine in good condition.
